Production systems are being restructured to close production cycles via implementing circular economy (CE) practices. The planted tree industry in Brazil has shown potential for applying CE practices due to its efficient use of resources and inclination towards environmental innovation. However, some gaps and difficulties have been observed in several industrial segments so that the logic of the circular production system is put into practice more effectively and intensely. In this context, the aim was to investigate the use and impacts of CE practices in the Brazilian planted tree industry by sector of operation and scale of enterprises based on the ReSOLVE framework. Data were collected from 34 companies that answered a questionnaire, corresponding to 47.2% of Brazilian planted tree industry companies. Data analysis involved univariate and multivariate statistical techniques, considering the grouping of companies by sector of activity (forest producer, pulp and paper, and timber processing) and scale (small, medium, and large). The results revealed that "pulp and paper" and medium- and large-scale companies had the most significant application of CE practices and reported more significant impacts. [Display omitted] • Explores a segmented analysis of the circular economy by scale and sub-sector groups. • Scores of circular practices and their impacts are presented according to the groups. • The association between circular practices and impacts by group are analyzed. • Propositions to enable the adoption of circular practices are presented.

This paper describes a cradle-to-gate life cycle assessment of offset paper production in Brazil. The production system is classified into two subsystems: a forest production subsystem, which involves seedling production, soil preparation, seedling planting, forest maintenance, and wood harvesting and transport processes; and an industrial production subsystem, involving wood pulp extraction and bleaching, chemical recovery, and offset paper manufacturing processes. The environmental analysis includes the primary energy demand, environmental impact assessment, and land use indicators. The primary energy demand indicated that the largest amount of both renewable and non-renewable primary energy is consumed by the industrial production subsystem, accounting for 91.0% of the total energy demand. The potential environmental impact assessment included eight impact categories: acidification, ecotoxicity, global warming, human toxicity – cancer effects, human toxicity – non-cancer effects, nutrient enrichment, ozone depletion, and photochemical oxidation. Most of the potential impacts are attributed to the processes of pulp extraction and bleaching, and offset paper manufacturing, mainly due to the production of electricity and thermal energy. As for impacts on land use during the forest activities, a recent developed approach was applied for the regionalized assessment of impacts. Land occupation impacts on erosion resistance, physicochemical filtration, and mechanical filtration showed a reduction in the soil ecological functions, whereas groundwater recharge indicated a credit for the performance of the soil function. With a view to reducing the main life cycle impacts of the industrial production subsystem, an evaluation is made of alternative production scenarios. The best scenario was the substitution of biomass and diesel in the energy generation unit by biomass gasification and optimization of the recovery boiler. [ABSTRACT FROM AUTHOR]

Environmental Product Declaration (EPD) and EPD-like demands have been gaining importance, particularly due to the release of Product Environmental Footprint by the European Union (EU). EPDs could be demanded in international trade, potentially creating a technical trade barrier for emerging economy countries. Thus, those countries should evaluate their readiness to successfully meet this demand. In this sense, this paper aims to analyse and propose strategies for EPD promotion in Brazil. Brazil's situation regarding life cycle assessment (LCA) and EPD development was analysed considering its business, academic, public policy and consumers contexts. In addition, an analysis of the strengths, weaknesses, opportunities and threats (SWOT) was elaborated based on interviews with EPD stakeholders in the country. These allowed some strategies to be proposed considering the principle of connecting strengths and opportunities, compensating for weaknesses and neutralizing threats. The results showed that Brazil has a technical and institutional context that enables EPD growth due to the initial stage of LCA database, EPD programs, stakeholders' engagement, and availability of experts. However, in general, these aspects aren't in an adequate level for successful EPD promotion. There is still a large path for EPD understanding and life cycle data availability. Besides, financial and technical restriction, especially considering small and medium-sized enterprises (SMEs), present structural barriers. Nevertheless, by promoting EPD, Brazil could have gains in terms of credibility, access to global markets and environmental awareness. The opposite could happen if the country doesn't seize these opportunities. Furthermore, to influence Product Category Rule (PCR) definitions was said to be a key opportunity to avoid rules that disregard Brazilian singularities. Strategies for EPD promotion should focus on sensitizing and engaging different stakeholders in strategic sectors (civil construction, paper and pulp, coffee, ingredients derived from soya and livestock), enhancing technical capacities and life cycle data generation, and strengthening EPD programs to boost the Brazilian internal market and PCR development. Brazilian institutions should be encouraged to follow international discussions on EPD and internalize them, fostering sustainable production and consumption in the country. [ABSTRACT FROM AUTHOR]

This paper aims to introduce a new sustainable business excellence model, called Knowledge Management Excellence Model 21 (KMEM21), a theoretical framework that combines Knowledge Management and Business Excellence Models (BEMs), proposing an approach applicable to organizations to directly contribute towards achieving the United Nations Sustainable Development Goals (SDGs). The paper through a qualitative-exploratory methodology makes an analysis and benchmarking, emphasizes the integration of Knowledge Management and three specific Business Excellence Models (Management Excellence Model (MEG) from Brazil, Baldrige Excellence Framework, and EFQM). This integration uncovers relationships between organizational concepts associated with Knowledge Management and BEMs, which contributes to new insights in the literature regarding these concepts' interplay. BEMs are presented as tools that can catalyze the power of Knowledge Management towards achieving SDGs. However, it's noted that the existing BEMs might not be adequate, as the goal extends beyond organizational improvement and excellence to encompass sustainable development aligned with SDGs. The article suggests that specific organizational concepts, identified through a literature review and aligned with Knowledge Management and BEMs, can be selected as indicators associated with the constructed KMEM21 and the SDGs. These indicators are intended to form a bridge between the new model and the SDGs. However, given the comprehensive nature of the theory, model development, application, result acquisition, and analysis, the article's primary contribution will be in its focus on elaborating the instrument and technique, demonstrating the creation of a theoretical framework for the SDGs. Future works will showcase the application of the proposed KMEM21 method in five Brazilian organizations, members of Global Compact, to compare the achieved objectives and the results obtained with the organizations' performance and their sustainability reports. [Display omitted] • There is a visible relationship between knowledge management and business excellence models, aided by shared organizational concepts. • Achieving the SDGs in organizations can be done by using the traits incorporated into knowledge management and business excellence models. • The Knowledge Management Excellence Model 21 represents an original approach, acting as a new sustainable business excellence model. • A comprehensive model can be constructed using a methodology that incorporates an instrument, a technique, and a method. • KMEM21 presents a strategic path that aligns with business excellence principles and the sustainable development objectives, offering a framework for organizational success.

Tropical climate-smart agriculture could be a cost-effective and scalable nature-based solution toward achieving net-zero greenhouse gas (GHG) emissions in the coming decades. Nevertheless, the lack of integrated on-farm CO 2 , CH 4 , and N 2 O flux measurements remains a barrier to including these systems in certification programs and the carbon (C) market. This systematic literature review critically examines field-measured GHG emission studies within climate-smart agri-systems in Brazil, aiming to: (i) integrate GHG-measured data, (ii) explore geographical representativeness and connections between organizations and authors, (iii) analyze distributions of studied GHG molecules, climate-smart system types, and productive components, (iv) conduct a meta-analysis on the adoption of climate-smart agriculture, and (v) identify methodological and scope gaps, providing insights for future research directions. The systems considered include no-till, well-managed pasture, integrated crop-livestock, and integration with trees (i.e., crop-forestry, livestock-forestry, crop-livestock-forestry, and multistrata agroforestry). Out of 1200 papers mentioning GHGs and climate-smart systems, 74 contained reliable on-farm flux measurements. Most authors were Brazilians affiliated with Embrapa and public Universities. Studies concentrated on the Atlantic Forest and Cerrado, with scarce data for other biomes. Over half of the trials assessed individual GHG molecules and only one climate-smart system. Urochloa spp. and Avena spp. were the most studied forage genera, while soybeans and corn dominated annual crops. Eucalyptus spp. and beef cattle were common trees and animals. No-till, integrated crop-livestock, and agricultural integrations involving trees showed soil C–CH 4 influx from 0.8 to 1.0 kg ha−1 y−1. Transitioning from pasture monoculture to integrated systems decreased N–N 2 O emissions by up to 1.63 kg ha−1 y−1. Converting extensive grazed land to intensified-integrated systems reduced animal CH 4 intensity, with cuts of up to 122 g CH 4 per kg of average daily weight gain. Future research must urgently address methodological issues, such as de-standardization (e.g., 8–10 flux units found per GHG molecule) and the absence of crucial ancillary variables. In conclusion, adopting diversified climate-smart agri-systems shows potential to mitigate GHG emissions, but caution is advised when extrapolating our numerical findings due to limited data across Brazilian edaphoclimatic conditions. We urge scientists to prioritize frequent on-farm measurements of all three GHGs (CO 2 , N 2 O, and CH 4) along with agroecosystem C sequestration across multiple climate-smart systems, enabling reliable and comparable net GHG flux calculations to identify the most sustainable option. Advancing and standardizing GHG measurements in Brazil offer an opportunity to enhance GHGs inventory accuracy, calibrate models, and promote policies and investments that expand refined tropical climate-smart agriculture. [Display omitted] • We systematically reviewed GHG measurements in Brazilian climate-smart agri-systems. • Well-managed pastures, no-till, and integration-based systems mitigate GHG emissions. • Brazilian GHG dataset incompletely represents systems and environmental complexities. • Producing agri-GHG field data is still vital for policies, investments, and C market. • Future GHG research should standardize flux units and include ancillary variables.

This paper aims to investigate the supply chain and reverse channels of expanded polystyrene packaging connection in Brazil and their roles to discuss the main challenges towards circular economy. In order to achieve this goal, we propose a four-step method, anchored in the literature, technical visits, and interviews with experts in the expanded polystyrene (EPS) industry. First, the EPS supply chain was characterised and mapped, and secondly, the stakeholders and logistics activities in reverse channels were analysed. Third, the Brazilian legislation and chain structure was reviewed to obtain an understanding of how this can influence the activities developed in reverse channels. Fourth, with an analysis of the data collected before, the barriers to implement EPS reverse chain were presented. The main results establish that the EPS can complete one cycle of the circular economy, which is recycling, but products need to be separated and washed. The most significant waste generators are public and private institutions, residences, and retailers. Notable barriers to its recycling are a lack of understanding of the nature of expanded polystyrene recycling by Brazilian people, high transport cost due to material density, and the dispersion of post-consumer expanded polystyrene in several regions of the country linked with the small number of recycling facilities. Finally, this issue could be explored in industries and companies that require their managers to adopt strategies to improve reverse logistics in order to promote the circular economy. The companies' actions could facilitate a stronger circular supply chain since they could increase recycling efforts, reduce expanded polystyrene waste, and present new business models. The resulting generation of employment would contribute to the quality of life of contemporary society. The findings presented in the paper enable industries to identify and guide the most demanding significant steps and processes, and to shift the reverse chain and expanded polystyrene recycling to ensure that they operate more efficiently. • Reverse logistics as the first step towards circular supply chain. • The paper maps the expanded polystyrene packaging supply chain and its reverse logistics. • This paper presents the barriers that hinder the reverse logistics in Brazil. • The main challenges are related to the consumers and the recycling industries.

Urban solid waste management (SWM) is a central problem in major cities worldwide. This topic is particularly relevant for developing countries, given the constant growth of slums. SWM is an essential part of sustainable supply chain management (SSCM), which appears to be a viable method of incorporating social, environmental and economic goals as pillars for the sustainable development of an organization and its supply chain. Although the literature offers a large and growing number of publications in SSCM and SWM, there is not yet a study that addresses SWM in a slum of a developing country from the SSCM perspective and there still a need for more sustainable waste management strategies involving all relevant stakeholders. Through a longitudinal case study conducted in the largest slum of Brazil (Rocinha), this paper aims to address these research gaps by developing a framework for SWM from the SSCM perspective in areas of slums. The research findings indicate that to tackle environmental problems related to SWM in such areas, it is necessary to solve basic social issues related to education, security, and infrastructure, with the integration and support of government, local community and industry. Although some progress has been observed in the last 10 years in Rocinha, the studied real-life setting shows that in practice, the performance of SWM stakeholders, particularly industry, is far from fulfilling the social and environmental pillars of SSCM. The proposed framework encompasses government and the community viewpoints in addition to the industrial focus and points to practical actions based on SSCM enablers, reinforcing a holistic and multi-perspective view, and the need for integrated management for better SWM in slum areas in developing countries. As it is a first attempt in this direction, additional research in similar settings is required to evolve the analysis towards more generalizable findings. • This paper analyses urban SWM from the SSCM perspective in developing countries. • A real-life setting of SWM in a large slum is analysed. • The industry should be more active in the social and environmental pillars of SSCM. • The paper offers actions for SWM in Rocinha in a model supported by SSCM's enablers. • A SWM framework is offered from a SSCM perspective orientated for areas as slums.

Two economic activities have been integrated in southern Brazil: olive cultivation and sheep farming. The favorable edaphoclimatic conditions in the southern region for cultivating olive trees and cultural preferences for the consumption of sheep meat make this integration a valuable strategy. Considering that every activity causes environmental impact and the exploitation of natural resources, new systems that promote sustainable development and the efficient use of these resources become necessary. This paper presents the first study of the carbon footprint of the life cycle of integrating of sheep and olive farming, with the objective to build an inventory based on primary data collected on olive and sheep farms in Brazil, determine the carbon footprint of the conventional and integrated system and estimate the potential for mitigating GHG emissions. The evaluation was performed using the life cycle assessment (LCA) methodology. The study focuses on the detailed analysis of the processes and activities that are responsible for GHG emissions, including enteric methane emissions, methane emissions from manure management, emissions from nitrogen fertilizer use and limestone application and energy consumption. For this, two major scenarios were considered, the first centered around on the traditional olive cultivation and sheep farming systems individually, and the second involved their synergistic integration. The findings indicate that the conventional system is associated with a global warming impact of 6.8 kg CO 2 eq per liter olive oil and kg live weight. In contrast, the integrated system demonstrates a significant mitigation potential of 27.7%, resulting in a reduced global warming impact of 4.92 kg CO 2 eq. This advantage is a consequence of the synergy between the systems, as they now occupy the same area, which allows the sharing of agricultural activities and agrochemical inputs, in addition to optimizing nutrient recycling and complementing each other. Additionally, the results of a sensitivity analysis showed that enteric methane from sheep and the application of limestone to the soil are the most influential parameters on the carbon footprint, indicating that they are key parameters for the development of GHG mitigation strategies, some of which were discussed in the article. • First life cycle assessment of integration between olive and sheep farming in Brazil. • The inventory was constructed with primary data collected in situ. • The study assesses the carbon footprint of the olive and sheep farming system. • The results show environmental advantages of the integration of olive and sheep farming systems.

Pastureland maintenance is seen as a land-based measure to reduce dependency on feed concentrates and mitigate greenhouse gas (GHG) emissions from livestock production in the EU, while providing other ecosystems services. This paper assesses potential market-mediated impacts, including global Land Use Change (LUC) and GHG emissions, from increased subsidies to pasture-based livestock production in the EU. A tax recycling strategy (TRS) is simulated against a baseline up to 2030 under the shared socioeconomic pathway 2 (SSP2). This implies a budget-neutral increase in the level of pasture subsidies in individual Member States, as land subsidies for other cropping activities decrease. We employ the computable general equilibrium (CGE) model GTAP in its recursive-dynamic version, GTAP-RDEM, extended with the Multi-Regional Input-Output (MRIO) database FABIO to disaggregate agri-food sectors from 21 to 31. This approach allows considering price- and income-dependent feedbacks when assessing long-run changes in the global economy, improving the sectoral resolution relative to GTAP v10. The policy increases pastureland areas and cattle production in almost all EU Member States, whereas cropland and crop production decrease, causing significant changes across EU agri-food markets. Crop prices increase, leading to the reduced output of intensive animal production sectors, mainly pig and poultry. Cropland areas decrease and most EU countries increase imports of grain, oilseeds, and cakes, essentially soybean cake from Brazil and North America. While GHG emissions decrease in those EU countries where pasturelands expand mainly at the cost of croplands, GHG emissions increase in those countries where pastureland expansion comes with forest loss. As a result, net GHG emissions increase in the EU-27 in 2030 (+2.49 Mt CO 2 -eq). Emissions from LUC in major non-EU grain- and oilseed-exporting countries increase, e.g., by 102.52 Mt CO 2 -eq in Brazil and by 129.17 Mt CO 2 -eq in North America. The simulated policy shows that promoting extensive livestock per se does not meet the objectives of the Common Agricultural Policy and the EU Green Deal. The TRS should be complemented with policies to foster crop diversification and promote the use of domestic feed sources (e.g., legumes) to effectively ensure feed self-sufficiency and that extensive cattle production in the EU does not lead to deforestation in carbon-rich countries.

Distributed generation (DG) plays a strategic role in transitioning from a fossil to a renewable energy matrix, encouraging the reduction of energy poverty and access to green energy in traditional communities. This paper proposes a statistical model based on structural equations to analyze the influence of DG on Well-Being (CWB), and to estimate the causal relationships between the latent variables: economic (ECO), environmental (ENV), social (SOC), distributed generation system (DGS) and well-being (CWB) in a rural area in Brazil. The research is carried out in a Quilombola Community located in the south of Brazil. In the data collection process, a questionnaire was used in a Likert scale format, applied in loco to the residents of the Quilombola community. This database was imported into the SmartPLS software for analysis using a partial least squares approach. Structural equation-based modelling (SEM) results confirmed 66% of the hypotheses. The latent variables SOC and DGS directly and positively affected CWB with (β = 0.573) and (β = 0.433), respectively. The Economic variable with (β = 0.396) had a direct and positive effect on the DGS variable, and the DGS variable with (β = 0.404) had an immediate and positive impact on the CWB. The variables observed with the highest participation in the latent variables were: belonging (62%), social capital (31%), greenhouse gases (56%) and incentive policies (45%). The proposed model demonstrates that socioeconomic changes, carried out from specific public policies around the installation of DG, should contribute to the well-being of traditional communities and the reduction of energy poverty. • An analysis of the well-being development of a rural community was done. • For data collection process was used a Likert scale. • Only the social dimension had a direct effect on the well-being of the community. • The designed model demonstrated that the variables are susceptible to changes, influencing on public policies. • DG promotes well-being beyond technical issues and should encourage its installation in rural communities.

Green Buildings Labels (GBL) are indicated as one of the means with the potential to contribute to sustainable development. Worldwide, more than 850,000 green buildings have already had their project and development helped by just three of the GBLs (LEED, BREEAM, and BASIX). Brazil, however, has only 874 LEED-certified projects. Aiming to propose strategies to foster the adoption of GBL in the country, this paper developed an interpretative model involving barriers to them in Brazil. For this, the technique of Validated Interpretative Structural Modeling (VISM) was developed aiming to add statistical validity to interpretative models even in situations of research with small sample sizes. VISM is a modeling technique that incorporates the simplicity of Interpretative Structural Modeling (ISM) with the significance testing procedures of Partial Least Squares - Structural Equation Modeling (PLS-SEM). Adopting the VISM, the barriers model was then developed in five steps: (1) identification of indicators; (2) definition of constructs; (3) identification of relations between constructs; (4) validation of relations between constructs; and (5) creation of the conceptual model. As a result, VISM proved to be an effective innovative modeling technique in the development of models for exploratory research and presents results consistent with the reality studied. Regarding the model developed, the main barriers identified by the study to the adoption of GBL in Brazil are: "environmental protection mechanisms"; "costs and return on investment"; "mistrust of the benefits from GBL"; "corporate and public awareness"; "maturity and market economics"; and the "project, construction, and operation of green buildings". • The paper develop a model of barriers to adoption of green buildings labels in Brazil. • The paper present the technique of Validated Interpretative Structural Modeling. • The technique can help exploratory research with small sample sizes. • ISM models with circular and cross relationships can be validated. • Environmental protection mechanisms and costs hinder green buildings labels.

The obligations arising from legislation and other instruments affect the macro-level decision-making related to the transition toward a circular economy (CE), which is a multifaceted topic since it tries to aggregate the interests of different stakeholders. In this context, this paper aims to analyse the current policies, strategies and initiatives related to the CE transition from a multicriteria perspective and under the lens of NIT (New Institutional Theory). This is the first approach that analyses which CE strategies and related practices boost the transition from a macro-level perspective, using a multicriteria method and considering developed and emerging economies. For this reason, this paper can be helpful for researchers and practitioners involved in implementing strategy and policymaking aimed at the transition toward a CE. It also contributes to the discussion on the global transition to the CE by identifying differences and similarities between countries. The proposed methodology has been applied to compare the realities in Italy and Brazil. The perceptions of several stakeholders from the two countries have been gathered through a questionnaire to evaluate numerous strategies against several social, environmental, economic, and technical criteria. The main results are: Italy presents a proactive behaviour, a higher level of institutionalisation, and a coercive isomorphism related to European regulations and strategies. In contrast, Brazil has reactive behaviour, a lower level of institutionalisation, and is impelled by mimetic isomorphism. Although it is possible to observe several advances in the last years in Brazil, the transition to a CE is still in the early stages compared to Italy. [Display omitted] • Transitioning to a new economic model is not a quick and straightforward process. • Transition requires changes in countries, regions, cities, supply chains and companies. • Some strategies and related practices have been adopted to enable the transition. • National legislation and Action Plans can boost the transition toward a circular economy. • In developing countries, the exploration of CE concept and its potential benefits has been rare.

Climate change impacts in one country can lead to impacts in distant locations, for example, via internationally traded crops. Previous work has highlighted a need to include cross-border climate change impacts in climate risk assessments, to describe the exposure and transmission of cross-border climate risk across actors, and understand options for managing this risk. In a case study of the Brazil-Europe soy supply chain, this paper aims to explore how stakeholders perceive past and future shocks, how climate change impacts affect stakeholders differently, and how they might respond. Soy is a key internationally traded commodity and Europe relies on imports for the majority of its soy consumption, used widely in livestock feed. Via 96 semi-structured expert interviews, we found different stakeholder groups are vulnerable to different types of weather shocks, experience different price and supply consequences, and have different capacities to respond. While some responses can reduce risk of impacts across the supply chain (e.g. new soy cultivars, improving transport infrastructure), we also identified examples where responses exacerbate risk for other stakeholders (e.g. export bans, changing demand). A holistic cross-border approach to analysing risk in the soy supply chain can help avoid maladaptation and offer opportunities for more collaborative adaptation. [ABSTRACT FROM AUTHOR]

Technical qualification is required to adequately meet the responsibilities related to solid waste management (SWM). Given that the successful SW policies requirements implementation at the local level relies on the ability to plan and the efficient management of public services, this paper aims to verify if municipalities have working teams that are prepared for this challenge. To accomplish this goal, three indicators were proposed to evaluate these human resources: Professional Qualification Level (PQL), Multidisciplinary Level (ML) and Leadership Level of Education (LLE). A proportional stratified sample with SWM leaders from 156 Brazilian municipalities participated in a survey. The results showed that although some municipalities were able to provide teams and find solutions to implement plans and actions, some smaller municipalities were not able to organize themselves adequately for this implementation. This paper provides a diagnosis of the human resources dimensions associated with the administrative capacity of municipal governments for the successful implementation of the Brazilian Solid Waste Policy (BSWP) at the local level. There is a need to improve the administrative capacity of municipalities to ensure the satisfactory implementation of the BSWP. The shortcomings identified in this paper should be addressed by the government to ensure that the constitutional right to waste management is achieved. [ABSTRACT FROM AUTHOR]

The shift from a fossil-based to a bio-based economy (bioeconomy) requires more efficient utilization of the biomass generated from agricultural production. This can be achieved through the cascading use of biomass, which also offers the potential of creating additional value from biomass by developing novel products. Taking sugarcane as a case study example, this paper aims to analyze how well Brazil, the world’s leader in sugarcane production, is positioned to reach these goals. The paper combines two conceptual tools: one is the ‘biomass-based value web’, which was developed as an extension of the value chain concept with the aim to capture the links within and between value chains that arise from the cascading and joined use of biomass. The other concept is that of the ‘national innovation system’ (NIS), which serves to identify the different types of actors involved in the biomass value web and the linkages between them. For empirical data collection, the study combined three methods: a mapping of the physical biomass flows in the value web, in-depth interviews with the actors involved, and the application of the ‘Net-Map’ tool to identify the actors in the NIS and their linkages. The findings show that the development of Brazil’s international competitiveness in sugar and ethanol was based on political incentives that resulted in a strong network of institutions that focused on these two products. However, to become a front-runner in the future bioeconomy, the existing innovation network needs to be expanded. In particular, it is important to integrate national and international private sector organizations. The findings also suggest that industries need stronger incentives to collaborate with knowledge institutions. Long-term consistent policies and funding opportunities for risky investments are also required to further strengthen Brazil’s innovation network to meet future opportunities and challenges of the bioeconomy.

This paper analyzes the significance of international conferences for higher education institutions (HEIs)’ promotion of sustainability. The paper has undertaken a detailed review of the scientific literature on strategies of HEIs to promote sustainability, hence identifying eight HEIs strategies that these institutions can adopt to become more sustainable (developing an Institutional Agenda, promoting Research, improving Teaching, enhancing green Campus Operations, stimulating community Outreach, and promoting Knowledge Dissemination). Based on this review, and focusing on knowledge dissemination, particularly on the academic events (conferences, seminars and workshops), 69 international academic conferences on sustainability were selected for analysis (from 2012 to 2016). From these conferences 21 proved suitable for a text mining analysis due to the data availability - i.e. articles published online. These articles were organized and submitted to the Collocations Extraction process, creating a list of important terms for each conference, based on their frequency in the articles. Furthermore, the relevance of these terms was tested using the Google Trends tool, to evidence the frequency of their Google searching. Finally, two conferences were selected for a more in-depth analysis, exploring their results and contributions (REGSA and LINKS conferences) to promote sustainability. The main results of the paper outline that international conferences have become important HEIs’ strategies to promote various issues of sustainability, through sharing knowledge, experiences, projects, initiatives and methods. It can be noticed a high interdisciplinary and multidisciplinary character of these events, illustrated by the multitude of promoted topics and participation, but also an increasing interest to actively involve stakeholders in discussing and promoting sustainability and sustainable development.

Alternative fuel vehicles (AFV) are a promising alternative to reduce greenhouse gas emissions in the transportation sector and ultimately, to contribute to a more sustainable society. Within the current commitments of the Brazilian Government to international agreements, in terms of emissions reductions by 2030, some new policies have been implemented, in order to incentivize the diffusion of AFV in the country. Yet, how will these policies contribute to the goal of increasing its fleet in the long-term, how long will it take and what are the differences (if any) among the policies, in terms of their effectiveness, are questions that remain unanswered. In this sense, the main aim of this paper is to investigate the impact of public policies in the long-term diffusion dynamics of AFV in Brazil. In order to do so, a system dynamics model is developed, based on the Generalized Bass Diffusion model, the Cobb-Douglas function and the learning curve theory. The model is used to test four different policies and some uncertainties related to: (i) the exemption of the import duty; (ii) the reduction of the motor vehicle property tax; (iii) the exemption of the tax on manufacturing goods; and (iv) a banning regulation for internal combustion engine vehicles in the long-term. The results highlight the importance of the current incentive policies but at the same time call for reinforcing efforts in order to increase the AFV fleet to significant values by 2030. Conversely, the banning regulation obtains a higher diffusion rate, but only achieves significant values by 2060. The paper concludes by showing the main contributions and policy implications of the effectiveness of the four policies studied as well as some suggestions for future work. [ABSTRACT FROM AUTHOR]

Technology parks promote science, technology and innovation through their components, such as high-tech companies, universities and incubators. They show a significant increase in the number of units, especially in emerging countries such as Brazil. Unlike the industrial and logistic parks that, due to functional requirements, have their pre-determined and standardized architectural and urban characteristics, technological parks have in the innovation, their main characteristic, the possibility of proposing more suitable spaces for urban innovation. The Roof Mosaic is an approach that seeks self-sufficiency in urban areas from the food-energy-water nexus, using rooftops to produce food, renewable energy and rainwater harvesting. The integration between technology parks and Roof Mosaic can be advantageous since their roofs have a lower slope and greater design flexibility than other parks and can, therefore, contribute to the sustainable development of cities. The aim of this paper is to evaluate the potential of technology parks when implementing the Roof Mosaic. A case study underway was used, which is the Federal University of Rio de Janeiro (UFRJ) Technology Park (Rio de Janeiro, Brazil). The results from the case study show the potential for: 100% food self-sufficiency using hydroponic production of lettuces and tomatoes, meeting the demands of approximately 3,300 people; 45.2% for energy generated from photovoltaic panels; and 43% for water reusing rainwater harvesting. The potential of avoided CO 2 emissions using rainwater for non-potable purposes, food production and renewable energy, presented of nearly 805 tons of avoided CO 2 equivalents.

Studies have demonstrated the energy savings potential of mixed-mode ventilated office buildings. Yet, it is important to widen the knowledge about how those buildings have been designed and built in practice, and which design parameters have greater influence on its energy performance. The aim of this paper was to evaluate how building envelope design parameters influence the energy performance of cellular mixed-mode office buildings, in order to identify key design variables. The analysis presents a comparison among literature research studies and typical construction practices from a sample of buildings located in the city of Sao Paulo, Brazil. According to a base case model, established based on the real buildings sample, three sensitivity analysis techniques were performed to obtain relative parameter sensitivity to thermal loads: OFAT, Morris and Monte Carlo. Results showed the importance of the window opening effective area and the reduced impact of the window-to-wall ratio on the energy performance of mixed-mode office buildings. By applying a multivariate regression model, it showed significant in predicting 78.1% of the variance in annual thermal loads. The accurate determination of annual thermal loads into mixed-mode office buildings can be used to optimize the envelope characteristics based on a combination of input data and the building geometry. Findings from this study could also be applied to other locations, provided that similar climatic environment and urban context are taken into account. • We evaluate the energy performance of mixed-mode office buildings. • A base case and its characteristics were defined based on a sample. • Typical construction practices versus theoretical studies were compared. • Three sensitivity analysis methods were applied and compared. • Multivariate regression model predicted 78% of the variance in annual thermal loads.

Enhanced silicate rock weathering for long-term carbon dioxide sequestration has considerable potential, but depends on the availability of suitable rocks coupled with proximity to suitable locations for field application. In this paper, we investigate the established mining industry that extracts basaltic rocks for construction from the Paraná Basin, Sao Paulo State, Brazil. Through a Life Cycle Assessment, we determine the balance of carbon dioxide emissions involved in the use of this material, the relative contribution of soil carbonation and enhanced weathering, and the potential carbon dioxide removal of Sao Paulo agricultural land through enhanced weathering of basalt rock. Our results show that enhanced weathering and carbonation respectively emit around 75 and 135 kg carbon dioxide equivalent per tonne of carbon dioxide equivalent removed (considering a quarry to field distance of 65 km). We underline transportation as the principal process negatively affecting the practice and uncover a limiting road travel distance from the quarry to the field of 540 ± 65 km for carbonation and 990 ± 116 km for enhanced weathering, above which the emissions offset the potential capture. Regarding Sao Paulo State, the application of crushed basalt at 1 t/ha to all of the State's 12 million hectares of agricultural land could capture around 1.3 to 2.4 Mt carbon dioxide equivalent through carbonation and enhanced weathering, respectively. This study suggests a lower sequestration estimate than previous studies and emphasizes the need to consider all process stages through a Life Cycle Assessment methodology, to provide more reliable estimates of the sequestration potential of greenhouse gas removal technologies. • First assessment of the burdens associated with enhanced weathering and carbonation. • Transportation of the material greatly impacts the sequestration potential. • The quarry to field offsetting distance is 550 ± 65 km for carbonation. • On Sao Paulo average, the practice emit 0.110 kg CO 2 eq per kg of CO 2 removed. • The setup burdens of the practice reduce previous sequestration estimates.

For environmental reasons, the production of plastic from renewable sources is gaining importance worldwide. In the case of polyethylene made from sugarcane-based ethanol, Brazil, being the world leader in sugarcane production, plays a fundamental role. Nevertheless, the absence of national regulations for monitoring the manufacturing process or verifying the biogenic fraction of what is already on the market raises concerns in Brazil. The main reason for the lack of such regulations is that the only approach fully capable of distinguishing identical chemical compounds of biogenic or fossil origin is the measurement of radiocarbon concentrations using an expensive and time-consuming method. Nevertheless, the measurement of stable carbon isotopes ratios has proven to be an acceptable approach to distinguish between C4 plant-derived plastics and petroleum-derived plastics. The present study compares the potential of the conventional mass spectrometry and radiocarbon accelerator mass spectrometry techniques as tools to determine the biogenic fraction of green polyethylene in Brazil. For plastics derived from either corn or sugarcane sources, δ13C values less negative than −20‰ indicate biofractions of 51% or higher. Other values would indicate the need to follow up to the radiocarbon accelerator mass spectrometry measurement, since it would not be possible to distinguish between lower biofractions and the presence of wheat or soy. The conventional mass spectrometry method can be employed for the preliminary screening of bio-based materials in manufacturing industries, representing a relatively cheap and accessible way of inspecting these products in developing countries. • Plastic marketed as bio-based may have petroleum as a significant source. • Biofractions of plastics derived from C4 plants can be resolved via IRMS analyses. • Sugarcane based plastics were measured by both IRMS and 14C-AMS techniques. • IRMS represents a cheaper alternative to 14C-AMS analyses in biofraction studies.

Due to its low global share of direct energy consumption and greenhouse gas emissions (1–2%), the implications of technological transitions in the agricultural and forestry sector on the energy system have been overlooked. This paper introduces the Agriculture and Land Use Sector module part of the ModUlar energy System Environment (MUSE), a novel energy system simulation model. The study presents a generalisable method that enables energy modellers to characterise agricultural technologies within an energy system modelling framework. Different mechanisation processes were characterised to simulate intensification/extensification transitions in the sector and its wider implications in the energy and land use system aiming at providing reliable non-energy outputs similarly to those found in dedicated land use models. Additionally, a forest growth model has been integrated to explore the role of reforestation alongside decarbonisation measures in the energy system in achieving carbon mitigation pathways. To illustrate the model's capabilities, Brazil is used as case study. Outputs suggest that by 2030 under a 2 °C mitigation scenario, most of Brazil agricultural production would move from 'transitional' to 'modern' practices, improving productivity and reducing deforestation rates, at the expense of higher energy and fertiliser demand. By mid-century Brazil has the potential to liberate around 24.4 Mha of agricultural land, where large-scale reforestation could have the capacity to sequester around 5.6 GtCO 2 , alleviating mitigation efforts in the energy system, especially reducing carbon capture and storage technology investments in the industry and power sector. • A novel energy-oriented agriculture and land use systems model has been developed. • Mechanisation levels are characterised using cluster analysis and linear optimisation. • Role of reforestation alongside measures in the energy sector in Brazil are studied. • By 2050, modern mechanisation could represent 54–63% of agricultural production. • Brazil has the potential to sequester around 5.6 GtCO 2 through reforestation.

Adoption of sustainable agriculture practices (SAP) has the potential to mitigate climate change's effects, while at the same time minimize degradation of natural resources and increase food production. However, recent policies based on economic incentives alone have largely failed to increase SAP adoption rate at farm level. Understanding farmers' perceptions towards environmental issues and climate change is essential to change this situation. This study aims to categorize farmers in different types, according to their perceptions on environmental issues and on climate change in a sample of Brazilian farmers (n = 172). Principal Component Analysis (PCA) and Cluster Analysis were used. Results showed four clusters of farmers: "Worried", "Apathetic", "Anthropocentric" and "Ecocentric". Contrasting to "Worried" and "Apathetic", farmers in "Anthropocentric" and "Ecocentric" clusters presented pro-environmental behavior, which suggests a high likelihood to adopt SAP. While farmers with an anthropocentric view are oriented to increase their economic gains, ecocentric farmers are motivated by environmental concerns i.e. non-economic factors. Insights of this paper can be used to facilitate effective policy development and strategies to increase the adoption rate of SAP. Image 10125 • The study examines the classified environmental behavior of farmers in Brazil. • Statistical analysis was used for the study. • Farmers who are ecocentric and anthropocentric exhibited pro-environmental behavior. • Pro-environmental behavior is not motivated exclusively by financial incentives. • Results will help to increase the adoption rate of sustainable agricultural practices in Brazil.

In 2015, the United Nation (UN) launched 17 Sustainable Development Goals (SDG) as part of an Agenda to be achieved by 2030. The target is having a global plan of action, aiming at universal peace and social and environmental justice. For this, 169 goals were drawn. The objective of this research is to discuss the congruence between mining activity and the SDG, starting from experiences of the scientific literature and the observation of one mining activity. For this purpose, the Web of Science and Scopus databases were used, with the keywords "sustainable development goals" and "mining". The Coordination of Improvement of Higher Education Personnel (CAPES) Portal was used to search papers that relate each one of the SDG to mining. Visits were made to three crushed stone mining industries, located in Monsenhor Gil, Piauí, Brazil, in order to follow the production process of the diabase mineral. From the research in the literature, it was possible to verify that there are several possibilities of reaching the 17 SDG in the mining sector, such as in the promotion of jobs (SDG 8), contributing to the reduction of poverty (SDG 1) and hunger (SDG 2), among others. From the visits, it was observed that the compliance with SDG related to the promotion of jobs, the improvement of income for community's residents, and the infrastructure of the environment are common to all mining or business activities that reach remote and poor areas. This is clear when identifying mining regions that have lost their economic importance once the local development ceases. If the visited industries left the place, it would cause great loss to the residents that depend on them for their jobs. There is a small number of women on the staff, setting up disrespect for SDG 5 regarding the achievement of gender equality. The nature of the activity itself does not justify the asymmetry that possibly happened under the influence of a sexist culture that imposes what is a man's job or a woman's job. Another point is the lack of investment in inclusive education for employees and for residents of the region. In addition, these industries do not recover the degraded areas, compromising the achievement of SDG 13, in regard to combat climate change and its impacts. [ABSTRACT FROM AUTHOR]

There are many definitions for the term Corporate Social Responsibility (CSR), but it can broadly be understood as a commitment that an organization must have towards society, expressed through actions and attitudes that affect it positively. In Latin America, in particular, this field is still at an initial stage, and few companies have actually developed and integrated CSR practices as part of their management system. This paper aims to present a set of CSR initiatives and projects developed by a Brazilian aircraft manufacturer, Embraer, considered an example of best practice in sustainable management practices. The paper also verifies if these activities are integrated into the company's management model in a mature way, as proposed by the literature. The research method used here was a case study with semi-structured interviews with a set of employees responsible for CSR at the company. The results gathered allow the projects developed at the company to be clustered around six main areas: excellence in education, social partnership programmes, entrepreneurship, corporate social responsibility, volunteering and preservation of the history of the Brazilian aeronautics industry. All these projects are exemplary managed and critically analyzed in relation to aggregation of value they provide to society, thus ensuring suitable results. As a conclusion of the survey, it was observed that Embraer has integrated the CSR practices with other existing management systems in a harmonious and mature form. The scientific value of this research lies in the presentation of CSR practices developed by one of the most important companies in Brazil, with a management system directed to excellence. Other companies and researchers can use these practices as a benchmark, or as examples of good CSR practice leading to tangible results. [ABSTRACT FROM AUTHOR]

The National Policy of Solid Waste, recently approved in Brazil, establishes the implementation of reverse logistics networks for several residues, such as electronic waste. One of the primary points of the legislation is the principle of ‘shared responsibility’, which establishes that all actors in a supply chain are responsible for the reverse logistics, such as manufacturers, distributors, importers, retailers, the government and the final consumer. This situation characterizes a group decision context and, emphasises the need of aggregate different and often conflicting viewpoints. Thus, this paper proposes the use of a specific Problem Structuring Method, the Strategic Options Development Analysis, which is based on the construction of cognitive mapping techniques, for developing strategic analysis based on the decision-makers' viewpoints. In order to apply the methodology, we conducted online workshops with 8 representatives of the stakeholders involved in this decision context. At the end of the process, four categories of actions to be implemented were found and developed: strategic, environmental, economic and social. These categories are based not only to technically assessment, but also on stakeholder's perspectives. The contribution of this paper is mainly related to the analysis and structuration of the problem of reverse logistics of electronic waste under a problem structuring methodology, which is few explored in the literature. This paper also contributes to researchers estudying reverse logistics of electronic waste, mainly in developing countries. [ABSTRACT FROM AUTHOR]

South Asian countries are the main players in the recycling industry, there are problems linked to contamination, occupational health, and procedures that are not sustainable. Due to recent regulations in the recycling industry, shipyards outside Asia with sustainable practices can be authorized by the European Union to participate in this market. Considering the fact that, Brazilian shipyards have not been contracting for new ship orders, their production capacity could be used to ship recycling. Then, the novelty of this paper's contribution is that it is the first study to examine the legal, technical, and economic aspects of ship recycling for Brazilian shipyards. The research strategy adopted was based data collected from ships recycled in south Asia in 2016 and the Brazilian fleet with the potential to be recycled over the next 25 years. Semi-structured interviews with maritime sector professionals, as well as shipyard stakeholders and ship owners, were conducted to identify the perception of this activity in Brazil. A statistical descriptive analysis was conducted and an estimate of global market value was determined considering the ships recycled. The findings indicate that, in 2016, India, Bangladesh, Pakistan, Turkey, and China were responsible for 96.64% of the global market. In the same year, approximately 27 ships were recycled out of South Asia showing a change in the predominant countries in ship recycling. The potential Brazilian fleet to be recycled over the next 25 years represents approximately 340 ships with an estimated market value of US $587 million. Brazilian shipyards are an environmentally and technically qualified industry, with an idle capacity of ±900,000 Tons per year. However, local and international stakeholders suggest that Brazilian shipyards need to acquire expertise and expand feasibility studies to develop ship recycling locally. [ABSTRACT FROM AUTHOR]

Abstract This paper aims to evaluate the possibility of using the roofs of habitations in Caruaru city in the semiarid region of Pernambuco, Brazil, for two purposes: as green roofs to mitigate extreme temperatures inside the houses and for rainwater harvesting and storage for potable purposes. For this, a preliminary study was carried out with inside and outside temperature monitoring of rooms with a green roof and conventional roof to verify the thermal variation in a real situation. Furthermore, the potential of rainwater harvesting for Caruaru city was evaluated based on precipitation data provided by the Water National Agency and an estimation of the available roof area (buildings and houses). In this context, two scenarios were analysed: (scenario 1) the whole roof surface was used for rainwater harvesting and saving and (scenario 2) green roofs were implanted in part of the roofs. The results of this preliminary study indicated that the use of green roofs resulted in lower temperature variations throughout the day, decreased internal temperatures, and decreased thermal amplitude in relation to a conventional roof (with tiles). Regarding the reduction of the catchment area because of the recommended use of green roofs in a semiarid region, considering green roof application just over the bedrooms (which was considered to cover 16 m2 in total), the water saving potential of the public supply system decreased, with a monthly average of 23.13% versus 28.43% (without green roofs). Implanting green roofs in part of the roofs of houses, although there is a reduction in the rainwater volume that can be harvested, can result in an increase in thermal comfort, whereas this is not feasible with the use of the entire roof area to harvest potable water. Thereby, the results indicate that the simultaneous use of the two kinds of roofs (conventional and green) is feasible even in a semiarid climate. Graphical abstract Image 1 [ABSTRACT FROM AUTHOR]

Abstract The objective of this paper is to test a procedure for assessing the adoption of sustainable practices in higher education technological institutions services, known as institutes of technology and polytechnic universities. The model, named Sustainability Assessment for Higher Technological Education (SAHTE), consists of 134 criteria that cover five aspects: 1) Governance/Policies, 2) People, 3) Food, 4) Energy/Water, 5) Waste/Environment. This structure is based on international frameworks and standards as GRI, AISHE, SAQ, GreenMetric, Green Report Card, and Campus Ecology. Seven higher technological education institutions are studied, providing data for testing the SAHTE model, as well as auditing the adoption of sustainability practices. The case studies, besides direct observations and document analysis, collected data from 170 interviews to faculty, staff, and students, and they show the lack of governmental incentives toward sustainability in Higher Education Institutions (HEI). Although, there is no external incentives that contribute for the adoption of best practices as green offices, the studied institutions show isolated initiatives that mostly are related to solid waste management. There is a consensus among the studied HEI directives that their educational programs does not address properly sustainability issues, which create a barrier for the academic community to perceive the importance to develop a sustainability model for managing HEI institutions. Sustainability in these organizations could be approached in the perspective of service operations and connect their contribution to value creation. In turn, that hinders the implementation of selective waste collection, for instance, a basic service operation that is still incipient in at least six of the seven institutions analyzed. In technological education, the correct treatment and disposal of laboratory waste offer a great opportunity to raise awareness among students, collaborators, and the community while preparing students for situations they will possibly face in companies. The results obtained by the SAHTE model may be useful for planning and developing policies concerning sustainable development, especially in service operations at the HEI examined.

Abstract This paper is a multi-case study of three oil and gas projects in Brazil that investigates the tacit knowledge on how to best manage energy use during the construction phase. Twenty-two in-depth interviews form the primary evidence of the case studies. The methodology incorporates network analysis of concepts that influence energy use to formalize the case studies and collect additional knowledge. The framework comprises thirteen construction activities and twenty-one systems and factors related to design, resources and site characteristics, specific to the construction domain. This set of concepts can influence the energy consumption during the construction phase. Although these concepts are present in nearly every project, their dynamics and their inter-relations with project-specific systems change, depending on the context of the project. The proposed method, which employs network analysis, help identify their interrelationships and relative importance of these concepts. In addition to the opportunities and lessons learned that can guide future energy assessments and improve energy use in construction projects, the results show how promising network analytics is to obtain knowledge usually difficult to perceive in traditional knowledge processes. Besides, this work highlights the importance of supporting collaboration between project team members to study and decide on the plans to manage/reduce energy consumption during the construction phase in oil and gas facilities. While the energy savings are smaller than the upstream and operation phases, it has received much less attention. It is also a phase with much more subjective and contextualized knowledge – making the use of case-based analyses more suitable. Highlights • Supports collaboration in studying and planning energy use during the construction phase of O&G projects. • Three case studies are conducted supported by in-depth interviews. • Network analysis is used to represent construction activities, factors and systems. • The approach represents a meaningful way to formalize the knowledge in the cases. • Can help formalize the knowledge contained in a text case.

Abstract This research paper identifies and quantifies the main criteria that define Corporate Sustainability (CS) based on data from large Brazilian companies participating in B3 (Brasil , Bolsa , Balcão), the Brazilian stock exchange. The data is derived from the 2015/2016 Corporate Sustainability Index (ISE) report. Initially, we applied Principal Component Analysis (PCA) on a sample comprised of sixty companies. Then, we organized and classified the scores for each criterion. Doing so, we are able to create a list of eighteen preponderant CS criteria, with respective components and dimensions. This list can be used as a reference for academic or practitioner studies. Notwithstanding, the main contribution of the present research is to unveil the inefficiency with which the social dimension is managed on CS issues. This gap related to the difficulties of assess and valuate social actions invites new studies on the way these aspects are being addressed on corporate level. [ABSTRACT FROM AUTHOR]

Abstract A number of governance mechanisms address socio-environmental challenges associated with commodity agriculture in tropical forested countries. Governance mechanisms that prove effective in one agricultural sector are often applied to other sectors as well. For example, voluntary certification programs have been adopted by producers of commodities as diverse as beef, coffee, palm oil, and soy. However, there are substantial differences in the extent to which governance mechanisms scale up and achieve impact in different sectors. This paper analyzes how the potential for scaling up a particular governance mechanism is influenced by environmental, market, and social geographies that differ between sectors. Through stakeholder interviews, farm-level surveys, and a literature review, we examine two types of voluntary governance mechanisms (third-party certification, and sustainable intensification programs) in the coffee and cattle sectors in Brazil, to understand why the two governance mechanisms have scaled differently between these two sectors. We find that third-party certification programs have scaled up relatively well in Brazil's coffee sector, more so than its cattle sector, in part owing to differences in sustainability priorities, market orientations, supply chain traceability, and social networks between the two sectors. We also find that pilot sustainable intensification programs in the cattle sector have had more success than certification in engaging farmers, in part because they involve less investment from participating farmers. We conclude that the distribution and quality of environmental resources, markets, knowledge, actors, and networks can play an important role in the ability of a governance mechanism to effectively take root.

The ethanol production chain is a complex system with a considerable number of actors and relationships. While Brazil stands out as a major producer of sugarcane ethanol, the production model in the north-eastern and southern regions is typically formed by small and medium production units, mostly associated to family-farming and associative production. This feature changes the relationships and profiles of the production chain, requiring understanding for the development of appropriate environmental, political, economic, social, ethical, and technological actions. This paper systemically maps variables that act in ethanol production chain in Southern Brazil, seeking to understand the interrelationships among its actors. Data collection was based on a review of the technical and academic literature and semi-structured interviews with different experts and actors of the chain. Systems dynamics diagrams model how the chain is configured and the main cause-effect interrelationships between the actors identified. Scenario analysis supports the analysis and discussion of the modelled context, seeking to contribute to the discussion about the competitiveness and economic sustainability of biofuel chains integrating associative production and family-farming.

This paper presents the first inventory and environmental impact study of the life cycle of coal obtained from a surface mine in Brazil. Significant reserves of coal in Brazil have attracted the attention of investors interested in building chemical and power generation plants. This inventory was developed to serve as a database for Life Cycle Assessment (LCA) studies, considering especially the impact of greenhouse gases, since there is no such information in the literature. The inventory collected data in situ, regarding the main pieces of equipment, inputs to the plant, and the direct emissions of greenhouse gases (GHG), covering different stages of the coal mining and processing, as well as the indirect emissions of GHG from the production and transportation of inputs. The coal life cycle emissions were equal to 3.29 × 10 −2  kg CO 2eq per kg of coal, of which direct emissions accounted for 98.3% of GHG, in which the major part was due to fugitive methane emissions from surface mining and post-mining coal crushing and handling operations. Additionally, the results of a sensitivity analysis showed that the diesel oil consumption was the most influential parameter of life cycle emission in terms of the inputs regarded.

Research on behavioral motivation for green product consumption has greatly advanced in recent years, but many unknowns remain, particularly regarding consumers' willingness to pay premium prices for products with ecological appeal. In this context, this paper reports an experimental research that investigates the relationship between consumer perceived value for green products and price elasticity. The research was performed using an adaptation of the model proposed by Zeithaml (1988) and it was applied in the automotive and furniture sectors. It was found that perceived value of green products increases willingness to pay in the purchasing decision. It was also observed that demographical variables, such as gender, age and revenue positively impact perceived quality and the consequent purchase intention. Considering the population sampled, results indicate that the effect of ecological appeal is similar to a 10% price reduction. It means that, according to the declared preference, respondents were willing to pay, on average, a 10% premium for green products in the studied product categories. The main theoretical contribution of our paper lies in furthering the understanding of how key dimensions that constitute perceived value relate to each other and to demographic and personal influence variables, as well as its impact in willingness to pay premium prices for green products.

Higher education institutes (HEIs) have made a deep commitment to prioritizing sustainable development (SD). Their task is to support practices that improve conditions in societies with respect to ecological, economic, and social issues, e.g., tackling the wicked problems of the world. In this case study, which took place at Feevale University (Feevale), Brazil, and at Häme University of Applied Sciences (HAMK), Finland, the following topics were studied: (1) whether there are international and national SD steering policies that might be relevant to higher education development in these particular universities; (2) whether this steering has impacted HEI's own SD policy and steering; (3) whether such in-house operations are affecting SD content within curricula; and (4) how a pedagogic approach influences the incidence of SD-oriented content at the bachelor's degree level. The analysis of policy level data was based on international and national policy papers recognized separately in both universities. As an indicator of the university's level of commitment to sustainability activities, we measured the incidence level of UNECE's SD themes in the curriculum. A hermeneutical approach was applied to the analysis to demonstrate possible systemic interactions between (inter)national SD policy and SD education at HEIs. At HAMK, some evidence was found of a national level top-down steering process in the university's SD activities. At Feevale, the enhancing of SD education is more of a bottom-up process. International steering appeared to be weak in both universities. The study uses unique quantitative data to show how the incidence of SD content in the curriculum is related to the pedagogical approach in each university [content (Feevale) vs. competence (HAMK)]. It was concluded that differences in national SD steering policy and pedagogical approach in the HEI led to divergent curricula structures in relation to the volume of the SD education between the two HEIs. Regardless of such a divergence, an appropriate balance between epistemic and ethical SD competences should be guaranteed for all bachelors. [ABSTRACT FROM AUTHOR]

Water is a finite and scarce resource that has gained importance in the global economic scenario. The sugar-energy plants use water intensively for the development of their activities, which demands that their top management incorporate actions to reduce or eliminate the use of this resource. In Brazil, the annual production of sugarcane is over 650 million tons/year and, on average, 1.18 m³ of water is consumed per ton of processed sugarcane. Given this, it is important to look for alternatives that allow the reduction of the volumes of water collection and use in Brazilian sugar-energy plants. The objective of this paper is to identify opportunities and challenges for using Cleaner Production (CP) to reduce water consumption in brazilian sugar-energy plants. To carry out this study, four case studies were conducted, whose data collection was based on semi-structured interviews with plant managers, document analysis and on-site visits. The case studies were analyzed individually, and then their cross-analysis were conducted in order to understand and present them in a transversal way to all the companies studied. Among the opportunities for improvement identified are the use of dry cleaning system for sugarcane cleaning, the classification and analysis of effluents, the analysis of the water consumption in the processes and the use of the system of concentration of vinasse. The main scientific contribution of this study is the systematization of CP interventions to reduce water consumption in sugar-energy plants, which expands the existing theory. The results of this work revealed that the opportunities and challenges presented may help companies to reduce considerably the volume of water used in their production systems, thus contributing to the preservation of the environment and the development of future generations.

Abstract: The concept of corporate social responsibility (CSR) is associated with the idea that every organization should integrate environmental, economic and social issues as part of their organizational philosophy. In companies with a higher degree of development in terms of CSR, sustainable practices are integrated into management systems. When focusing on Latin America, this integration may be at its first steps, but there is a vacuum in the literature in this field. Based on this reality, this paper aims to evaluate the integration between CSR practices and management systems in companies in Brazil based on experts’ perceptions. Employing a conceptual model covering how stakeholder demands are incorporated in organizational practices using a continuous improvement approach, we performed a survey with experts in the area. Results revealed opportunities for improvements in all CSR practices evaluated, most of which were considered by the experts to have been implemented only superficially. In a comparative analysis, two practices stood out in relation to the others: reporting of CSR results to stakeholders and evaluation of the performance of CSR activities using pre-established indicators. Practices associated with planning of CSR activities are the most superficially implemented, adversely affecting CSR performance. The authors believe that the findings of this study could be useful for business managers and academics as guidance towards improved CSR efforts. [ABSTRACT FROM AUTHOR]

This paper focuses on an analysis of the energy mix profile and energy efficiency of the Brazilian dairy industry. It investigates dairies’ energy mix and energy efficiency and identifies some actions for a cleaner energy mix. Primary data from 37 dairy cheese-making establishments distributed among the Brazilian regions were obtained from online surveys. The results indicate that woodfuel plays a critical role, being the most used fuel in thermal energy generation, while diesel is dominant in electric generation. It also emphasizes that only 51% of the dairy establishments utilize electric energy generators. Other alternative biomass sources are still incipient in the sector, restricted to just 9.5% of the cases for thermal energy generation and no cases for electricity. Regarding the energy efficiency analysis, the results suggest dairies are more scale efficient than pure technical efficient. However, the dairies present a low energy efficiency level. There is no evidence that inefficiencies are differently distributed according to their size. These findings are important for government agencies, industry associations, scientists, universities and research institutes. High inefficiencies, regarding the use of electricity and thermal energy, are a key issue in sustainable bioenergy production. [ABSTRACT FROM AUTHOR]

The need to consider environmental and social issues on a par with economic concerns in policy, plan, programme and project making in order to achieve sustainable development has been widely recognized. However, to date there has been no adequate implementation, and economic issues are frequently prevailing over other aspects. In many developing and emerging economies, a perceived urgency to promote economic growth frequently means that environmental and social costs of development are overlooked. It is within this context that this paper explores the consideration of environmental and social issues in transport policy, plan and programme (PPP) making in Brazil, an emerging economy which over recent years has invested heavily in its transport infrastructure. Aiming at establishing the extent to which environmental and social issues are considered and identifying the barriers for better practice, legal and institutional frameworks for transport PPP making, the substantive focus of PPPs as well as perceptions of actors involved in their preparation are investigated. Results show that whilst the need to respect environmental and social issues is recognized in sectoral guidelines and underlying values, in practice they are poorly considered. Main constraints to a better consideration of sustainable development in transport PPP making include the lack of instruments for a systematic consideration, the nature of existing PPP making processes and the dominance of political and economic interests. Moreover, suggestions for improvement are limited and mainly relate to external pressures. In this context, Strategic Environmental Assessment in particular would need to be introduced as an instrument for a more rigorous and clearly prescribed consideration of environmental and social issues.

The consolidation of the biorefinery concept has the potential to contribute to the sustainable development of agro-industrial regions, particularly in developing countries. The industrial symbiosis (IS) approach can leverage this potential through industrial cooperation, fostering new businesses, innovation and job creation coupled with reduced environmental impacts. We argue that coupling the biorefinery concept and the IS approach would invigorate traditionally agricultural regions, relying on endogenous vocation to promote sustainability. The purpose of this study is to examine the potential for development of an agro-industrial symbiosis network (ISN) from the construction of a biorefinery in the Norte Fluminense region (Brazil) – a region that has become highly dependent on oil & gas revenues but still has a tradition in agriculture and agro-industry. In this paper, we present the scenario analysis performed to design the agro ISN and an initial quantification of potential benefits. Four scenarios were developed (reference, short, mid and long terms) with the support of a synergy matrix and material flow analysis. Eighteen waste streams were identified and sixteen were addressed through the scenarios. In the long-term scenario, 14 productive activities could compose the agro-industrial symbiosis network, 8 of them as newcomers. “Quick-wins” were identified as residues in the reference scenario (CO 2 , fusel oil and used yeast) that could be absorbed by industries currently operating in the region. The emission of respectively 350 thousand and 55 thousand tonnes per year of solid waste and CO 2 would be avoided in the long term. Also, the production of succinic acid would provide additional revenue of at least US$19 per tonne of bagasse, adding higher value to the feedstock in comparison to electricity production. This study can prompt current recycling regulation towards multi-sectorial arrangements, which can better contribute to regional resilience than the single-sector reverse logistics’ arrangements that became recently mandatory with the National Policy on Solid Waste.

A constant evolution in the efficiency of production systems and government policies has enabled the control of the environmental impact of production activities and encouraged companies to develop strategies to achieve more sustainable operations. Despite this, more needs to be done to reduce the risks of globalised production activities. In this context, evidence suggests that Lean Manufacturing (LM) and Cleaner Production (CP) make a positive contribution to the environmental performance of organizations. However, very little has been reported in the scholarly literature regarding the convergence and divergence of these two approaches. This work therefore attempts to take advantage of the synergies of LM and CP by proposing a Lean Cleaner Production Benchmarking (LCPB) method to assess the practices and culture regarding the application of CP in companies. The method considers the management aspects of people, information, products, suppliers and customers, management and processes, as well as the LM practices that contribute to a more eco-efficient production. LCPB uses a methodology based on benchmarking that was applied to 16 Brazilian manufacturing companies in order to assess their practices and performances regarding CP. The method seeks to provide a diagnosis to verify whether CP is effectively carried out by the companies, and what their performances are regarding actions beneficial to the environment. The application of LM practices that contribute to CP was also evaluated through the proposed LCPB method. The paper contributes to the theory by proving further evidence of the compatibility and synergies of LM and CP. In addition, it proposes a novel method that enables the analysis of companies' practices and performances related to CP, assesses their actions associated with sustainability, and contributes to identifying points where there is a lack and difficulty regarding CP. The proposed method helps to relate LM and CP activities, indicating that companies that seek to apply LM concepts are those that present high CP practices and performance. [ABSTRACT FROM AUTHOR]

Crop-livestock-forest (CLFi) and crop-livestock (CLi) systems are among the most recent agricultural developments in Brazil, and aligned with the principles of cleaner production. Such integrated systems can provide at least three types of product from the same land area over a defined period. This paper presents a holistic sustainability evaluation using life cycle assessment to compare combinations of integrated and conventional systems in the Brazilian Cerrado region. The study assesses a comprehensive set of indicators in the three sustainability dimensions: environmental, economic, and social (socio-eco-efficiency). By prioritizing CLFi, the production area to meet the demand of grains, meat and energy for 500 Brazilians, from 2007 to 2014, reached 70 ha, while the conventional systems would need 420 ha to meet the same demand. This result shows that it is possible to increase production to meet the growing food global demand without the need of expanding the agricultural frontier, preserving the remaining forestland. CLFi combinations systems decreased 55% in climate change potential (2389 t of CO 2 equivalent), when compared to the conventional systems. It was also observed that the more integrated systems improved the quality of employment, promoted future generation investments in society, and decreased the total production costs in 54%, when compared to conventional systems. Therefore, intensification achieved through good practices such as association, rotation, and succession by an agroforestry system, optimization of inputs (including water, energy, fertilizers, and crop protection agents), land use, soil quality, biodiversity and social aspects.

In the last few years, a rapid increase in the population has been observed in many places. The majority of the population lives in urban areas, and experiences several problems related to an inefficient water supply and the occurrence of precipitation extreme events, such as a long dry season or the occurrence of floods. This framework allows consideration of the harvesting and storage of rainwater in tanks for immediate or future use. The harvesting, storage and use of rainwater in urban areas can create a positive impact on the public water supply system through a reduction in the demand for and use of potable water. Brazil experiences both water scarcity and abundance, due to the large dimensions of the country, imbalances in the population distribution and the timing of precipitation. From north to south, there is a wide variety of climates with distinct regional characteristics, including areas of semiarid climate; these are at risk of flooding due to rainfall concentration in few heavy showers and, on the other hand, are also susceptible to drought. Based on precipitation data and other information, an investigation was carried out into the potential of rainwater harvesting in the semiarid region of Brazil. There are 1133 municipalities within the defined semiarid region of Brazil; these municipalities are in nine states (Ministry of National Integration, 2005), including Pernambuco. In this region, the conventional public drinking water supply system covers 60% of the population, distributing water nine and five days per month to the inhabitants of the urban and rural areas, respectively. The potential for potable water savings was estimated for the urban areas of several cities within the semiarid region in Pernambuco State, northeast Brazil, using the methodology proposed by Ghisi et al. (2006) and Belmeziti et al. (2013). Ghisi et al. (2006) applied this methodology to cities in the southern region of Brazil and Belmeziti et al. (2013) used the methodology proposed in Municipality of Colombes (Paris Region). The results show that savings in water supplied by the public system can reach 25%; this paper discusses in an innovative way the savings in water supplied by the public system in a dry climate. The results indicate that a reduction in the pressure on the public water supply system is possible, simply by incorporating rainwater harvesting into the standard practices of local inhabitants.

Recognizing the need to increase energy efficiency across various sectors of the economy, the Brazilian government through the national energy efficiency plan (adopted in 2011) seeks to avoid 30 million tons of CO2 emissions through a reduction in electricity consumption of about 10% by 2030. Notwithstanding, we believe that a complete realization of such initiative will be dependent on the level of substitutability between different production factors and fuel types. Using the translog production function method, this paper, first provides insight on the economic impact of both factor and fuel inputs in Brazil. Most importantly, we examine the possibility of substitution among capital, labor, petroleum, and electricity. The ridge regression technique was used to estimate the parameters after our data depicted the existence of multicollinearity. Our results show that capital and labor are positively linked to output; however, petroleum and electricity contribute negatively to economic output in Brazil of which corruption is a plausible reason. Again, all variable inputs are substitutes with their relative technological progress depicting features of convergence. This implies that Brazil can achieve a cleaner energy system without much challenges due to the possibility of switching from greenhouse gas (GHG) emitting petroleum to a cleaner energy electricity. Our findings also highlight the importance of policies that advance merger of enterprises, and renewable energy use. [ABSTRACT FROM AUTHOR]

Cattle ranching in Brazil is a key driver of deforestation and greenhouse gas (GHG) emissions. The Brazilian government plans to reduce national GHG emissions by at least 36%, partly by reducing emissions in the livestock sector through strategies such as intensification, pasture improvement, and rotational grazing. In response, sustainability programs promoting these practices have begun operation. Though studies have previously investigated aspects of GHG emissions and sequestration in improved pastures, they have not linked improvements with programmatic interventions. We surveyed 40 cattle ranchers located in the Brazilian Amazon biome to investigate how GHG emissions differed between farms participating in livestock sustainability programs with intensified production and farms not participating in these programs. We found that participating farms produced 8.3 kg of CO 2 e/kg of carcass weight (CW) less than did non-participating farms, which represents 19% fewer emissions. Farms that had participated in a sustainability program for at least two years showed larger differences in emissions: 19.0 kg of CO 2 e/kg CW less for program farms compared with their counterparts, or 35.8% fewer emissions. Key drivers of the total CO 2 e/kg CW in all farms were enteric fermentation and manure management. This paper provides farm-level data supporting intensification as a possible strategy to reduce emissions per kilogram of beef produced, and suggests that future research efforts should focus on long-term impacts of intensification and expand metrics for success beyond GHG calculations.

Abstract: This paper presents the first findings of an ongoing multi-national research project between universities in Brazil, Chile and the UK funded by the UK Economic and Social Science Research Council (ESRC) and the Department for International Development (DFID). The Choices project seeks to analyse contextual understandings and practices of ethical consumption in Chile and Brazil. In a further step, it explores how ethical consumption and public procurement can be associated and used to foster sustainable development. The paper presents the outcomes of the first stage of the project, an extensive literature review considering the developing trends towards “ethical”, “sustainable”, “responsible” and “conscious” consumption in both countries. Chile and Brazil are former developing countries, and although they both now have growing ethical consumption movements, we argue that these are shaped by the specificities of each country's political, economic and institutional trajectories. In one case, Chile, ethical consumption has arisen from market forces, with lead actors being companies, consultancies and citizen and consumer organizations. Brazil, on the other hand, provides also a very interesting case for studying how ethical consumption is embedded in another Latin American context: it has a larger state sector and a domestic market size to give the state, and thus the consecutive centre-left governments, great regulatory power, since it can control firms' access to this market. Both cases showed the increasing role of corporate social responsibility discourses and practices interfacing with concepts of ethical consumption. As a consequence, the paper identifies a risk of firstly, “greenwash” and “whitewash” by large companies and secondly, of having small producers struggling to market their products.

Abstract: The main objective of this study is to verify the influence of Environmental Management (EM) on Operational Performance (OP) in Brazilian automotive companies, analyzing whether Lean Manufacturing (LM) and Human Resources (HR) interfere in the greening of these companies. Therefore, a conceptual framework listing these concepts was proposed, and three research hypotheses were presented. A questionnaire was elaborated based on this theoretical background and sent to respondents occupying the highest positions in the production/operations areas of Brazilian automotive companies. The data, collected from 75 companies, were analyzed using structural equation modeling. The main results are as follows: (a) the model tested revealed an adequate goodness of fit, showing that overall, the relations proposed between EM and OP and between HR, LM and EM tend to be statistically valid; (b) EM tends to influence OP in a positive and statistically weak manner; (c) LM has a greater influence on EM when compared to the influence HR has over EM; (d) HR has a positive relationship over EM, but the statistical significance of this relationship is less than that of the other evaluated relationships. The originality of this paper lies in its gathering the concepts of EM, LM, HR and OP in a single study, as they generally tend not to be treated jointly. This paper also provided valid empirical evidence for a little-studied context: the Brazilian automotive sector. [Copyright &y& Elsevier]

Over the past few decades, companies have shown growing concerns in relation to the environmental impact of their manufacturing activities. Green supply chain management (GSCM) has been considered by the manufacturers as a feasible option to reduce the environmental impact of operations while simultaneously improving their operational performance. The literature suggests that further research on institutional pressures, performance, and environmental practices are needed, especially in the case of developing countries. The present paper explores the GSCM pressures, practices, and performance observed in suppliers of a Brazilian automotive supply chain. The data were treated using partial least squares structural equation modeling (PLS-SEM) provided by SmartPLS software. The results show that the economic and environmental performance of the studied supply chain is positively related to the adoption of GSCM practices. In addition, the present research also identified the institutional pressures that influence this supply chain to pursue green supply chain management practices. The results of this study provide managerial and theoretical approaches for different industries in Brazil to focus on environmental awareness by adopting GSCM practices. In addition, this study helps increase confidence among managers and policy makers of Brazilian companies in the adoption of GSCM practices to improve firm performance. [ABSTRACT FROM AUTHOR]
