In recent years, concerns regarding the environmental impact of microplastics (MPs) have led to increased international attention on these pollutants. Although the initial focus was largely directed toward marine environments, land-based pollution sources, including MP release, have been recognized to directly affect marine ecosystems. Therefore, soil-, atmosphere-, groundwater-, and river-based research is ongoing. However, when considering sources of MP, it is necessary to examine the circular system of plastic in terms of raw materials, production, consumption, discharge, and disposal (recycling). Accordingly, the present study proposes a strategy to effectively manage MPs using this circular system. First, the factors influencing MPs in the circular system were identified, and MPs at the system's final stage, i.e., at the waste treatment facility, were subsequently investigated. Using the concept of MP waste (MPW), strategies were then developed for effective MP management within the circular system. Applying the proposed theoretical strategy to the Korean waste management system revealed that the new policy framework improves the current MP management system. Overall, this study provides fundamental data for establishing new or improved MP management schemes from a waste sector perspective. [ABSTRACT FROM AUTHOR]

As a crucial step in addressing the climate emergency and enhancing energy security, the European Union has set ambitious targets to decarbonise its economy by 2050. While the building sector plays a pivotal role in this transition, being accountable for 36% of the EU's total carbon emissions, it shows a renovation rate below 1% per year, which is clearly insufficient. To address this challenge, this study uses the cost-optimal methodology from private and social perspectives to assess the cost-effectiveness and environmental impact of five renovation packages with passive and active solutions currently available on the Portuguese market. The results demonstrated that from both perspectives, optimal combinations of market solutions were generally cost-effective and could lead to a 90–99% reduction in energy needs and even to zero carbon levels. Nevertheless, beyond cost-effectiveness, consideration of co-benefits, e.g., social and health improvements, is also crucial, requiring government action. To drive these essential changes, effective policy measures are imperative. Recommendations encompass robust regulatory frameworks, financial support mechanisms, knowledge dissemination, and a shift towards broader-scale renovation. For carbon reduction to be economically attractive, fostering innovative business models and leveraging legal instruments to tackle complex scenarios are needed. [ABSTRACT FROM AUTHOR]

With the increasing demand for digital innovation scenarios, it is important to complement and improve the policy system for the governance of digital innovation activities. Combining the previous research results on the analysis of antecedent variables, basic effects and potential mechanisms of digital innovation, and based on the citation analysis of digital innovation topics based on the Citespace method, we find that in the past two decades, the topic of digital innovation policy research has gradually shifted from focusing on "constraining policies to control negative impacts" to focusing on "constructive policies to expand positive impacts". The digital transformation has brought about multidimensional and profound impacts on the governance of innovation activities, and it is necessary to accelerate the theoretical research on policy frameworks for the new areas of technology socialization effects. Summarizing some of the important progresses, we propose a policy framework covering three aspects: policy needs for sustainable transformation of digital innovation, policy orientation and policy dimensions for sustainable transformation of digital innovation, creating R&D opportunities, optimizing R&D organization, building ecological advantages, improving R&D governance, knowledge creation, enabling applications, collaborative promotion, standardizing management, national digital innovation system, digital innovation foundation, data governance capacity, digital security and other aspects of the conceptual framework of the basic policies for sustainable transformation of digital innovation. The research viewpoints and conclusions are of theoretical reference value for further research on key policy conditions for digital innovation, major policy impact effects and digital innovation governance mechanisms.

The broad spectrum of bioresource use makes it challenging to interconnect strategic objectives and policy planning documents without compromising a coherent development vision. Bioeconomy development directions have been defined at the EU and Latvian levels. Nevertheless, to facilitate their implementation, the goals must be consistent with those specified in relevant national policy planning documents and vice versa. To determine whether internationally defined bioeconomy objectives are implemented in Latvian policy planning documents and what priority is given to them, a mixed methods approach was used—a systematic literature review combined with a keyphrase assignment approach. The results are summarized in an illustrative screening matrix and aggregated using the TOPSIS method to identify in which policy planning documents bioeconomy objectives are prioritized and to what extent. The results have shown a high prioritization of bioeconomy objectives in Latvian policy planning documents, especially in hierarchically higher documents. [ABSTRACT FROM AUTHOR]

Land use land cover (LULC) modeling is considered as the best tool to comprehend and unravel the dynamics of future urban expansion. The present paper provides a comprehensive review of existing LULC modeling techniques and novel approaches used by the research community. Moreover, the review also compares each technique's applications, utility, drawbacks, and broader differences. The rationale behind such a comparison is to highlight the strengths/weakness of individual techniques. The review further highlights the utility of the hybridization of different techniques (e.g., machine learning model combined with statistical models) to LULC modeling to complement their strengths. Although significant progress has been made in LULC modeling, the review highlights the need to incorporate the policy framework into LULC modeling for better urban planning and management. The present review will help researchers and policymakers to achieve better land management practices and ultimately assist in achieving Sustainable Development Goal-15 (SDG-15) (i.e., life on land).

The international maritime sector plays an important part in contributing to the global sustainable economy and plays a significant role in achieving sustainable development goals. A variety of regulations and standards power the sustainability management of the global maritime sector, including the United Nations' Sustainable Development Goals and the European Union's new draft European Sustainability Reporting Standard. Limited research on the potential contribution of maritime policy-making to support sustainable development has led the sector to face multiple challenges. In this study, we analyzed how local policy-making can impact international goals and global sustainable development based on comprehensive datasets of 143 maritime companies. The study recommends the incorporation of sustainability dimensions of the maritime sector into all levels of policy-making and supporting the policy implementation with the local maritime governance structure. A maritime country should have strategic planning objectives that embrace maritime affairs and use the interactions identified between local development and the maritime sector. We propose a framework for maritime policy-making that supports sustainable development. A maturity model for sustainable development in the maritime sector was developed. The results can be used as guidelines for policymakers in planning sustainable development in a maritime country. [ABSTRACT FROM AUTHOR]

Although decoupling tourism growth from carbon emissions is vital for sustainable tourism development, the driving forces of tourism carbon decoupling in the Yangtze River Economic Belt (YREB) are little known. Herein, our study applies the geo-detector model and the Tapio decoupling index to investigate the decoupling trend and driving mechanism of the tourism economy in the YREB from carbon emissions from 2009 to 2019. Our results show that (1) the tourism carbon decoupling status has gradually evolved from connection to decoupling, and the average decoupling index was optimized from 1.36 in 2011 to 0.34 in 2019; (2) the dominant factors promoting the evolution of decoupling are the industrial structure (with an average q of 0.64 (2009–2019)) and the urbanization index (with an average q of 0.61 (2009–2019)), with government policy, technological innovation capability and consumption, and regional GDP also being important drivers; and (3) the double and nonlinear enhancement between the driving factors imply that regions in poor decoupling areas, such as Shanghai and Chongqing, can promote the evolution of decoupling through multi-factor interactions to realize the sustainability of the tourism industry. Finally, an integrative and proactive policy framework that has important theoretical, methodological, and management implications for the construction of green demonstration areas in the YREB is proposed.

Urbanization challenges regional sustainable development, but a slight expansion mechanism was revealed in a plateau city. We have integrated the urban expansion process and analyzed its determinants in Lhasa (Tibet), and we provide insightful suggestions for urban management and planning for Lhasa. The full continuum of the urban expansion process has been captured using time-series of high-resolution remote sensing data (1990–2015). Four categories of potential determinants involved in economic, demographic, social, and government policy factors were selected, and redundancy analysis was employed to define the contribution rates of these determinants. The results illustrate that considerable urban expansion occurred from 1990 to 2015 in Lhasa, with the area of construction land and transportation land increasing at rates of 117.2% and 564.7%, respectively. The urban expansion in the center of Lhasa can be characterized as temperate sprawl from 1990 through 2008, primarily explained by governmental policies and investment, economic development, tourist growth, and increased governmental investment resulting in faster urban expansion from 2008 to 2015, mainly occurring in the east, south, and west of Lhasa. In contrast with other cities of China, central government investment and “pairing-up support” projects have played an important role in infrastructure construction in Lhasa. The miraculous development of the tourism industry had prominent effects on this economic development and urbanization after 2006, due to the running of the Tibetan Railway. An integrative and proactive policy framework, the “Lhasa development model”, having important theoretical, methodological, and management implications for urban planning and development, has been proposed.

The link between health, socio-economic status and the living environment is increasingly moving into the focus of public health research and policy. The aim of the European Union's Project "Joint Action Health Equity Europe (JAHEE)" is to enable countries to identify and implement needs-based measures to promote health equity. In one of JAHEE's work packages, focusing on healthy living environments as a strategy to tackle health inequities, a Policy Framework for Action (PFA) has been developed. This article gives an insight into the core contents of the PFA, which are valid beyond the project boundaries for all actors that work at the intersection of community health promotion. The PFA was developed as a consensus document in a participatory process between the members of the work package and an interdisciplinary German team of public health experts. Results from project meetings of the partner countries as well as research findings and recommendations from field experts were incorporated. Reducing health inequalities in public health is a cross-sectional issue that needs to be addressed across all policy areas. The municipality setting is of particular importance in this context, as it offers many starting points and can coordinate between all relevant actors with an overarching strategy.

With an increasing use of plastic, considerable plastic waste is generated, threatening the environment and public health. In particular, changes in living patterns in urban areas have significantly impacted the rate at which plastic waste increases every year. Thus, governments in many developed countries have implemented numerous policies to reduce plastic waste generation. Among them is the concept of circular economy that aims to protect the environment from plastic pollution and promote growth and innovation in industry and human life through overall changes in designing, producing, using, and recycling plastic products. The Korean government has implemented the Resource Circulation Act (RCA), which includes the concept of circular economy and resource efficiency policy for overall waste management. Following the concept of RCA, the Plastic Waste Control Plan (PWCP) was established for the comprehensive management of plastic waste. Therefore, this study introduces the goals and strategies of PWCP, which has a circulation system of four stages of production, consumption, discharge, and recycling, as well as the major roadblocks in the stages impeding the achievement of the goals and strategies. This study also suggests countermeasures at the government level for solving the major problems in the four stages. [ABSTRACT FROM AUTHOR]
