Geotechnical constructions involve consumption of a vast amount of non-renewable natural resources and energy- and carbon dioxide-intensive materials (e.g. cement and steel) that contribute significantly to global warming and climate change. This paper uses drilled shafts as an example to illustrate the importance of environmental impact assessment in the design phase of foundations. Life-cycle assessment (LCA) is used to quantify the environmental impacts of construction of single drilled shafts and groups embedded in sandy soil profiles. Parametric studies are conducted to investigate the effects of soil properties, design parameters and hauling distances of construction materials and equipment on the environmental impacts of single drilled shafts. For pile groups, different configurations, applied load, centre-to-centre spacing and thickness of pile cap are considered in the parametric study. The global warming impact and human toxicity of a typical drilled shaft are found to be 39 and 486% of annual world impact per person, respectively. Based on the study, charts and tables are developed that may be used for quick estimation of the global warming impact of drilled shafts without the use of specialised LCA software programs.

• Literature review papers related to the tourism-energy nexus are analyzed. • Four main groups are identified considering the quantitative methodology used. • Topics and discussions on the nexus between tourism and energy are developed. • Future research is discussed. The high dependence of tourism activities on energy consumption, and particularly on non-renewable energy, is a major barrier to building sustainable tourism models. For this reason, the analysis of tourism and energy use is a growing field of study within sustainability debates. Despite this, there is a gap in the literature and, to the best of our knowledge, there is no previous study that critically reviews the vast literature on the energy-tourism nexus. This paper aims to fill this gap in tourism knowledge. The main objective of this article is to conduct a systematic review of scientific studies with a quantitative empirical basis that examine this nexus, trying to answer the following questions: What are the main methodologies used to approach the tourism-energy nexus? which indicators or variables are relevant?; is there a consensus on the results?; and what are the main lines of discussion on the use of energy in tourism? To this end, we particularly focus on the main methodologies, results and perspectives during the period 2001–2021. A total of 1,189 articles were reviewed by abstract and title, 236 were included for the full review and 163 were finally selected. The results show how the nexus and energy dependence of tourism is assessed mainly from four major methodological groups: G1) econometric models, regressions and other statistical methodologies (67% of the sample); G2) surveys, questionnaires and energy audits (15%); G3) Life Cycle Analysis (13%) and G4) other approaches and environmental impact indicators to assess the relationship between energy and tourism (5%). The analysis between the causal relationships between tourism development, economic growth, energy use, environmental degradation and energy efficiency of accommodations are the main issues evaluated, considering a wide range of indicators/variables. Based on the gaps and limitations found in the literature review on tourism and energy, it is discussed how some findings should be interpreted with caution due to their methodological approaches and differences. Finally, some of the main lines of future research in this field are also presented. [ABSTRACT FROM AUTHOR]

This paper analysed and summarised the significant research outputs published on the environmental impact assessment of mining and mineral processing industries through life cycle assessment. The paper presents valuable insights in identifying the gaps, where should the focus be in the mining and mineral processing industries for a sustainable future. Mining and mineral processing industries have been the key focus of research in many countries due to its increasing sustainability concerns that affect global warming and climate change. Use of heavy equipment that consumes electrical energy, mechanical energy, and an enormous amount of process heat is a key contributor to the overall impacts in the industry. Due to the use of heavy equipment and associated energy consumption, these industrial sectors contribute notably to global warming, human health, ecosystems, and resources. Among the various environmental impact assessment tools which are widely used to identify sustainability indicators, life cycle assessment (LCA) is a well-justified approach among the practitioners and researchers. Though state of the art technological tools and resources are being used now a days, there is still a research gap in identifying the key mining processes which need to be the focus of attention. Renewable energy integration in the mineral processing sector and process heating from green energy sources is becoming the emergent field of research. The review results reveal, the assessment indicators in human health and ecosystems are key factors that are mostly missing in the previous studies which are crucial for people or community living nearby mining area. This review paper identifies the research gaps to the existing literature that can form the base for future research direction in the field of LCA and sustainable energy integration in mining and mineral processing industries. • A review based on life cycle assessment studies in mining and mineral processing. • 16 metal mining industries are reviewed. • Summarised key factors of environmental effects using LCA. • Future research directions are highlighted.

Abstract The Sustainable Development Goals agreed by the United Nations in September 2015 comprise 17 goals and 169 targets aimed at integrating matters related to sustainable development into the overall economic, environmental and social frameworks of countries. Whereas the SDGs have a global dimension, their action implementation depends on the level of priority different countries give to them, and on how sustainability issues compete with a country's main problems. The aim of this paper was to identify the main Sustainable Development Goals approached by experts from different geographic regions, according to their experience and research area, and to discuss the relation between these goals and the main local issues and challenges of each region. The methodology starts with snowball sampling to collect information from experts from all geographic regions, through contact networks of universities in different countries. With the information about the goals researched by the participating experts, an analysis of the relation between the study focus and the geographical regions of origin was conducted. A total of 266 specialists from North America, Latin America/Caribbean, Africa, Asia, Europe and Oceania participated in the survey. Based on the sample used, it can be said that there is a relation between the local problems or challenges observed in some regions and the main areas of interest of the surveyed experts, with a general emphasis on the study of goals 4, 11 and 13. Based on the data gathered, the paper presents a set of examples of positive and negative situations in the various regions, and considers the extent to which some Sustainable Development Goals are being pursued by research on a worldwide basis. Graphical abstract Image Highlights • The SDGs are now being implemented by many countries. • There are differences in the emphasis to the implementation of the SDGs across different geographical regions. • Goals related to Climate Action, Sustainable Cities and Education seem to be among the most popular ones. • The research gaps suggest that many SDGs deserve more attention in order not to "leave anyone behind".

This paper provides an overview of the interrelationships between tourism and sustainability from a cross-disciplinary perspective. The current challenges and barriers in the tourism sustainability, such as high energy use, extensive water consumption and habitat destruction, are first reviewed. Then the key cross-disciplinary elements in sustainable tourism, including green energy, green transportation, green buildings, green infrastructure, green agriculture and smart technologies, are discussed. To overcome the challenges and barriers, a few implementation strategies on achieving sustainable tourism from the aspects of policy/regulation, institution, finance, technology and culture are proposed, along with the framework and details of a key performance indicator system. Finally, prospects of the potential for tourism to contribute to the transformative changes, e.g., a green economy system, are illustrated. This paper shine a light on issues of importance within sustainable tourism and encourage researchers from different disciplines in investigating the inter-relationships among community/culture, environment/ecology, and energy/water/food more broadly.

Highlights • An integrated approach is developed for environmental sustainability. • Climate variability has significant impacts on local environmental sustainability. • Rio Grande Basin is sustainable under current climate conditions. • Rio Grande Basin will become less sustainable in the late 21st century. Abstract Extreme weather events have been affecting local environmental sustainability. Previous literature in this field evaluates environmental sustainability based mainly on past and current resource consumption and availability, however, knowledge about the status and potential changes of environmental sustainability under future climate extremes is missing. This paper proposes an integrated approach (combining the Ecological Footprint Analysis with econometric regressions) to predict future environmental sustainability under different climate scenarios. Based on the case study of the U.S. Rio Grande Basin, the results show that this region has been sustainable in 1982–2012, although sustainability levels have been declining over time. In addition, projections for the future show that the entire region will most likely move away from sustainability by the end of this century under the high emission scenario (e.g., RCP8.5). These findings are relevant for sustainable resource management and allocation of local environmental resources as well as for decision-making support regarding climate risk adaptation and mitigation strategies.

This paper presents life-cycle environmental impacts and health hazards of the ilmenite and rutile processing routes which are very little explored despite a significant quantity of production worldwide. The study is carried out through a life-cycle environmental-impact assessment of the ilmenite and rutile mining production processes in Australia, using the International Reference Life Cycle Data System (ILCD) method under 14 significant impact categories and the Cumulative Energy Demand (CED) method for 10 significant impact categories. The dataset is collected from EcoInvent and the Australian Life cycle assessment database considering Australia as the geographic region. The major impact categories are climate change, human health (cancer), human health (non-cancer), ecotoxicity, and eutrophication. The analysis results show that the highest impact is caused in climate change, at 0.295 kg CO 2 eq, which is due to the large amount of electricity consumption in the ilmenite extraction process. Then, human toxicity-non cancer effects (4.42E-09 CTUh) and particulate matter (0.000155 kg PM 2.5 eq) are also noteworthy. Water resources depletion is affected due to the chemical emissions from ilmenite ore, which are found to be 0.00163 m 3 water eq. Rutile production impacts greatly on climate change at 1.535 kg CO 2 eq owing to large-scale electricity consumption. Electricity consumption for rutile also affects human toxicity-non cancer (2.3E-8 CTUh), particulate matter (0.00081 kg PM2.5 eq), and terrestrial eutrophication (0.024 molc N eq). Water-resources depletion from rutile is due to the ore, which are found to be 0.0085 m 3 water eq. The comparative assessment between ilmenite and rutile implies that rutile has more impact on the environment than ilmenite due to the electricity consumption and fossil fuel consumption. This result is validated through further analysis using the Cumulative Energy Demand method. A sensitivity analysis is also carried out to elucidate that the electricity grid mix from country-to-country contributes to sustainability by reducing the environmental impacts significantly.

Transdisciplinary research is increasingly used in projects dealing with transitions to sustainable, resilient and low-carbon societies. Transdisciplinary research projects require collaboration and coordination between researchers from different disciplinary backgrounds. Academic literature provides valuable insights on designing, facilitating, leading and evaluating transdisciplinary projects. While a substantial body of literature explores the challenges associated with transdisciplinary research, there is a scarcity of case studies exploring the challenges faced during different phases of project execution. In this paper we present a reflective account and analysis of our experiences during the first fifteen months of a transdisciplinary research project. The project is used as a case study, following a participatory action research methodology. Our findings verified the three types of challenge mentioned in the literature – inherent, institutional and teamwork related. This paper identifies a fourth type – emergent – that has not been discussed in the literature. Emergent challenges introduce uncertainty into TDR projects and are uncontrollable. Such challenges require research consortium leaders to develop adaptive strategies, and to take a mediation and leadership role in dealing with them. The article makes the following recommendations: emergent challenges require emergent strategies; funding should be more flexible to account for the nature of TDR research; TDR could be evaluated on the basis of its overall impact rather than on inflexible ‘deliverables’; academic publishing strategies must be incorporated into TDR projects; team development and co-location should be facilitated; and academic institutions should include performance and promotion criteria encouraging researchers to undertake roles in TDR projects.

Life cycle assessment (LCA) is an important tool to evaluate environmental ‘hot spots’ in livestock systems and recommend production improvements. However, it is common for livestock LCA to investigate only a narrow subset of environmental impacts to simplify results for decision-makers, which makes it difficult to fully understand the tradeoffs among environmental impacts and identify the most relevant mitigation options. We completed a systematic review of the livestock LCA literature to better understand the impact categories included and the progress made towards more comprehensive LCA. Our search of publications between 2000 and 2016 identified 173 relevant peer-reviewed papers. Nearly all the publications (98%) included climate change as an impact category and almost one-third of the publications (28%) focused solely on that one category. Biodiversity, ionizing radiation, and particulate matter were the least common categories addressed. Cattle LCA, including dairy or beef, were the livestock species most frequently evaluated. Our analysis shows that while the number of multi-category livestock LCA (LCA with 4 or more impact categories) increased over time, LCA including 1–3 impact categories (which we define as “simplified LCA”) increased at a higher rate than multi-category LCA. Simplified LCA therefore remain the most prevalent in the literature. Publications that included multiple impact categories were better able to identify environmental impact tradeoffs among livestock production systems and management scenarios. To compare results across livestock LCA studies, it is necessary to increase the standardization of system boundaries, functional units, impact frameworks and mandatory inputs. The optional steps of normalization and weighting in the life cycle impact assessment can also help decision-makers prioritize which environmental impacts to address. More work that includes a greater number of impact categories in livestock LCA is sorely needed to more fully understand and to harmonize the communication of the environmental performance of livestock production systems.

Sustainability is a paradigm that affects many sectors due to an increasing of stakeholders’ pressure, economic or political reasons. The wine industry is concerned about sustainability in both senses: it confronts threats from sustainability issues, such as climate change, chemical exposure and water and energy availability and its activities have their own impacts. In this sense, understanding sustainability in the wine world requires identifying definitions and principles, but also a review of current practices. This paper sets forth a cross-country analysis about current sustainability assessment frameworks in six countries (South Africa, Australia, New Zealand, US, Chile and France) in order to identify their main aspects, drivers and issues. A cross-analysis discusses the presentation, the scale, the scope, the governance, the deepness, the learning potential and the content, in a cross-disciplinary perspective. The common grounds are summarized in terms of main indicators linked with official guidelines. Most of the frameworks are certifications or labels in voluntary programs, using a qualitative approach to check compliance with guidelines, without proposing the improvement of sustainability performance. They are more focused on operation and on mitigating impact. All frameworks have indicators considering the main environmental issues to the wine industry. The frameworks development should move toward a more effective proposition for improving wine sustainability, in order to answer to the operational challenges with a strategic thinking. The analysis performed can contribute to the development of sustainability programs, improve current methods and encourage the diffusion of sustainability practices to the individuals or in terms of national programs.

Abstract: During the last decades numerous environmental problems have been exacerbated, and in some cases created. Traditionally, such problems have been addressed through environmentally sound technologies. The diffusion of such technologies has, however, been slow, where the focus has primarily been on high-polluting sectors. This paper explores the environmental actions of a relatively low-polluting sector, the insurer industry, in regards to environmentally sound technologies, by schematizing the concept of environmentally sound technologies as it is defined in Agenda 21. The Agenda 21 definition is critical when discussing environmentally sound technologies, as typologies of academic scholars are defined from the perspective of manufacturers ignoring the role of relatively low-polluting sectors when dealing with environmental issues. Five focus points from a climate change statement issued by the Nordic insurance industry are then integrated into the schematic framework. Case study examples from 16 Nordic insurance companies and secondary data of insurers' activities are used to illustrate insurers' role in enhancing development and utilization of environmentally sound technologies. Although the insurance industry offers many examples of its role in the development and utilization of environmentally sound technologies, this paper highlights the following points (1) there are still areas for improvements, (2) there is a large capacity that could be utilized, and (3) business opportunities are expected to increase once climate change consequences become more apparent. Due to the slow uptake of environmentally sound technologies, it is important to strengthen the focus on the role and obligation of low-polluting sectors as a part of the supporting infrastructure dealing with environmental sustainability issues. This paper shows the potential of opportunities arising from the synergies between environmentally sound technologies and finance and service providers to address such issues.

Air travel plays a vital role in today's life because it makes remote destinations accessible and short getaways possible. Despite its benefits, air transportation contributes heavily to climate change. Behavioral change is seen as a key driver in mitigating the environmental impacts of air travel. One way to encourage behavioral change is to use eco-labels. This study explores how an eco-label could be developed for the airline industry to function as a potential driver for behavioral change. 12 interviews with airline industry experts were conducted and thematically analyzed. Empirical results were then combined with prior research and the following five criteria essential for the development of an airline eco-label were identified: credibility, comparability, clarity, transparency and participation. Out of these five criteria, participation seemed to be the most challenging to realize. Based on these criteria, this paper could be understood as a first step towards the introduction of an industry-wide eco-labelling scheme for the airline industry that could help reduce the environmental impacts of aviation through behavioral change.

This paper is about the identification of the changing world climate drivers and speculation concerning the future impact such drivers will have on countries in the southern hemisphere, especially Australia and New Zealand. A focus for the above is a case study of climate change which has induced severe hardships in the Bendigo region of Victoria, Australia. The authors are of the opinion this experience, in this extremely climate sensitive agricultural area, is a forerunner to what could occur to many regions in the southern hemisphere. The case study shows the vulnerability of communities to instruments of governance established during periods of stability and urges the urgent need for modified governance instruments during periods of rapid climatic change. The paper commences the discussion about the meaning, relevance and reality of sustainability for communities during times of climatic uncertainty. [ABSTRACT FROM AUTHOR]

Biogas-linked agro-ecosystems provide economic and environmental benefits by using resources in a multipurpose manner. They utilize an energy consumption pattern that has prominent advantages in relieving energy shortages and reducing environmental pollution. To better understand the effects of these multiple aspects, it is important to study how much of the energy flow is extracted and available through the biogas-linked agro-ecosystem using an economic input–output evaluation or ecological and social influence assessments. It is also equally important to understand the conversion efficiency during the life cycle of biogas production, and how humans influence the whole process of the biogas-linked agro-ecosystem. This paper attempts to establish a life cycle-based accounting model of a household biogas system using different economic and ecological metrics for multiple objective considerations, to provide a powerful and comprehensive perspective to illustrate sustainability problems. In this study we use a typical household biogas system in Gongcheng Autonomous County (Guangxi Province, China) as a case study to reveal an effective route and strategy to relieve energy shortage, reduce environmental pollution, and improve human productivity. In this way, we can construct an exemplary example of how to realize sustainable development in a rural area with positive objective conditions. [ABSTRACT FROM AUTHOR]

This paper reports the pros and cons of co-management (i.e. concerted actions towards climate change and air quality management) through local sustainability initiatives using three case studies, each encompassing the planning and management issues at local government levels. Case study I is policy-based and reports the outcome of a consultation exercise while case studies II and III have greater scientific bearing. These case studies pave the way for development of a more integrated Climate Change Strategy Action Plan at local scales, specifically regarding policies on emissions sources from transportation and decentralised energy. They highlight the merits and the trade-offs of implementing local scale co-management practices, using a more integrated planning framework than what is currently under offer. We recognise that delivery of such ambitious, cross-cutting agenda may be impeded, primarily owing to limited expertise in assessing the synergies and the expected outcomes from cross-fertility between these two arenas. This calls for a step-change through more cohesive, cross-disciplinary policy frameworks, going beyond the local administrative spheres to maximise the co-management potentials while mitigating the wider environmental impacts.

Abstract: This paper considers life cycle environmental sustainability of solar water heating systems in regions with low solar irradiation, such as the UK. The results suggest that flat plate collectors have slightly lower environmental impacts than evacuated tube designs. Reducing the current energy losses of 65%–45% would reduce the impacts by around 35%. Compared to a gas boiler, solar thermal systems are a better option for only five out of 11 environmental impacts considered, with global warming and depletion of fossil resources being lower by 88% and 83%, respectively. Other impacts such as human and eco-toxicity are up to 85% higher. The solar systems score better relative to electrical water heating for eight out of 11 impacts. They are also environmentally more sustainable than heat pumps for seven categories. However, their potential is hampered because they need a back-up heating system, typically gas boiler. For this reason as well as due to a lack of suitable locations and poor efficiency, the potential of solar thermal systems to contribute to a more sustainable domestic energy supply in the UK is limited.

Estimation of emissions of greenhouse gases (GHG) is becoming an established part of assessing sustainability within environmental impact assessment (EIA). However, a comparative study of 25 environmental impact statements (EISs) to analyse the practice of accounting for emissions during the EIA process suggests that consideration of the effects of development on emissions of GHG is poorly understood. The extent to which assessment is actually carried out is also inconsistent and sporadically implemented. A key indicator appears to be the varying and sometimes contradictory use of technical terminology, particularly of the term ‘carbon’ and its similar phraseology. This paper provides a critical evaluation of the differing terminology that is applied to GHG assessments undertaken as part of EIA process and explores the effect that misuse of these terms could have on an impact EIS.

Abstract: Facing climate change and growing energy prices, the use of bioenergy is continuously increasing in order to diminish greenhouse gas emissions, secure energy supply and create employment in rural areas. Because the production of biomass or biofuels, wherever it takes place, comes along with externalities, positive or negative, the need for biomass and bioenergy sustainability criteria is more than ever felt. Research on sustainability criteria and certification systems has started through several national and international initiatives. Considering the benefits of an increased use of bioenergy but also the urge for limiting potential negative environmental and socio-economic impacts, the aim of these initiatives was to make the first move regarding bioenergy sustainability, while waiting for the European legislation to regulate this crucial issue. Land use changes, whether direct or indirect, are one of the most important consequences of bioenergy production. While direct land use changes are more easily assessed locally, indirect land use changes exceed the company level and need to be considered at a global scale. Methodologies for dealing with direct and indirect land use changes are proposed among others in the European, Dutch, British and German sustainability initiatives. This paper aims at presenting and comparing those four European initiatives, with a focus on their propositions for direct and indirect land use changes assessment. Key issues are discussed and recommendations are made for steps to overcome identified difficulties in accurately assessing the effects of indirect land use change due to bioenergy production.

Building regulations and governmental policies create pressure on the construction industry to minimize the environmental impacts that are caused by buildings. Achieving energy efficiency, and thereby low-carbon construction, is only possible by cooperation among the participants in the construction supply chain. Clients in particular have an important role in promoting environmental sustainability. In this paper, the carbon-reduction process is analyzed from a construction client's perspective. A framework is developed to analyze the interrelated components of this process, including the drivers, initiatives, challenges, facilitators, solutions, and achievements. A qualitative case study methodology was employed to gain a better understanding of the project-based practices and corporate policies in achieving energy efficiency. The study presents the results of three award-winning construction projects from the U.K. in which innovations for improving environmental sustainability were based on the Code for Sustainable Homes. The study outlines the initiatives and strategies of clients for carbon reduction, obstacles faced by project teams, mechanisms that helped overcome the difficulties, and low-carbon solutions applied to design, construction, and operation in the selected cases. Effective leadership, corporate responsibility, a focus on end users, repeatable nature of projects, and integrated teams are found to be the main success factors. The findings of this study are expected to guide construction professionals in implementing innovative low-carbon practices in collaborative project environments. The proposed framework can be used to better understand the carbon-reduction process in other projects and other countries where different regulations and conditions prevail. [ABSTRACT FROM AUTHOR]

Abstract: The purpose of this paper is to provide a broad overview of the social and environmental costs and benefits of biofuels in Asia. The major factors that will determine the impacts of biofuels are: (1) their contribution to land-use change, (2) the feedstocks used, and (3) issues of technology and scale. Biofuels offer economic benefits, and in the right circumstances can reduce emissions and make a small contribution to energy security. Feedstocks that involve the conversion of agricultural land will affect food security and cause indirect land-use change, while those that replace forests, wetlands or natural grasslands will increase emissions and damage biodiversity. Biofuels from cellulose, algae or waste will avoid some of these problems, but come with their own set of uncertainties and risks. In order to ensure net societal benefits of biofuel production, governments, researchers, and companies will need to work together to carry out comprehensive assessments, map suitable and unsuitable areas, and define and apply standards relevant to the different circumstances of each country. The greatest benefits may come from feedstocks produced on a modest scale as co-products of smart technologies developed for phytoremediation, waste disposal and emissions reduction.
