Special Issue Information

Dear Colleagues,

The pressing need to mitigate climate change has brought carbon neutrality, or achieving net-zero carbon dioxide emissions, to the forefront of global priorities. As highlighted by the United Nations, the transition toward carbon neutrality is critical for guaranteeing humanity's quality of life and respecting the planet's limits. Achieving this ambitious goal requires collective action across all sectors of society. Governments, organizations, academic institutions, and industries worldwide are increasingly incorporating sustainability into their missions, not only to address climate challenges but also as a value that enhances their social and environmental accountability.

This Special Issue aims to explore innovative, scalable, and practical solutions for reducing carbon footprints and progressing toward carbon neutrality. Contributions should be aligned with the multifaceted dimensions of sustainability, environmental, economic, and social, while addressing global and local challenges. Original research articles, case studies, and comprehensive reviews are welcome.

Potential topics include, but are not limited to, the following:

  • Strategies for carbon footprint reduction and management in organizations, institutions, and industries;
  • Environmental, social, and governance (ESG) strategies for promoting sustainability and carbon neutrality;
  • Development and evaluation of technologies promoting carbon neutrality;
  • Smart energy systems for sustainable development;
  • Advances in energy-efficient systems and low-carbon industrial processes;
  • Hydrogen energy and its role in the transition to carbon neutrality;
  • Solar energy innovations and applications for reducing carbon footprints;
  • Wind energy and ocean energy as sustainable alternatives for energy generation;
  • Measurement, compensation, and mitigation of greenhouse gas (GHG) emissions;
  • Innovative programs and projects for GHG capture, utilization, and storage;
  • Process control and smart systems to optimize operations;
  • Renewable energy solutions for decarbonization;
  • Energy transition policies and incentives;
  • Sustainable infrastructure and urban planning;
  • The role of digital technologies in decarbonizing the telecommunication, transportation, electricity, manufacturing, and service sectors;
  • Circular economy approaches to achieving carbon neutrality.

This issue seeks to

  • Highlight cutting-edge research contributing to carbon footprint reduction and carbon neutrality solutions.
  • Foster interdisciplinary collaboration to address sustainability challenges across environmental, economic, and social dimensions.
  • Present case studies demonstrating applications of innovative technologies and practices that lead to achieving carbon neutrality.
  • Inform policymakers and stakeholders about viable strategies, practices, and technologies for reducing greenhouse gas emissions and promoting sustainable development.

With the acceleration of global industrialization, energy consumption and environmental problems are becoming increasingly serious issues. As an important measure to deal with climate change in China, the low-carbon city pilot policy is of great significance to the improvement of urban green energy efficiency. Based on the panel data of 285 prefecture-level cities in China from 2011 to 2022, this paper systematically evaluates the impact of low-carbon city pilot policies on urban green energy efficiency and its mechanism. The study found that the low-carbon city pilot policy significantly improved urban green energy efficiency, with an average effect of 0.023 units. The policy effect shows obvious regional heterogeneity, especially in the eastern region, large cities, and non-resource-based cities. Further analysis shows that industry chain toughness, green finance and technological innovation are important intermediary paths for policy to play a role, and there is a significant synergy among the three. In addition, the policy also shows a spatial spillover effect, which has a positive impact on the green energy efficiency of adjacent cities. Finally, based on the results, this paper discusses and puts forward targeted suggestions for policy making. This study provides an empirical basis for optimizing low-carbon policy design and promoting regional coordinated development, and has important reference value for achieving the goal of sustainable urban development.

In the context of global climate change, carbon emission trading (CET) has become a critical tool for driving urban green economic transformation. Since 2011, China has launched CET pilot programs, supporting the achievement of the “dual carbon” goals. Studying the relationship between CET and urban green economic efficiency is essential for advancing urban green economic transitions. However, the existing research is limited by its single-perspective approach, insufficient exploration of mechanisms, and weak heterogeneity analysis, which restricts a comprehensivethe comprehensiveness of our understanding of policy effects. To address these gaps, this study is the first to integrate macro-regional data with micro-enterprise behavior, evaluating the impact of CET on urban green economic efficiency from a dual macro–micro perspective, thereby filling the research void in macro–micro data integration. At the macro level, this study employs panel data from 281 Chinese cities spanning 2007 to 2020, using fixed-effects and difference-in-differences (DID) models to assess the impact of CET on urban green economic efficiency. At the micro level, a game-theoretic pricing decision model is constructed to reveal behavioral differences among enterprises in complete and incomplete information markets and their indirect effects on green economic efficiency. The findings indicate that CET significantly enhances urban green economic efficiency, with technological innovation, green finance, and industrial structural upgrading serving as mediating mechanisms. Heterogeneity analysis shows that the effects are more pronounced in eastern, non-resource-based, small-to-medium-sized, and non-old industrial cities. The game-theoretic model further demonstrates that enterprises in complete information markets more effectively indirectly enhance green economic efficiency through CET mechanisms. By combining macro and micro perspectives, this study provides a new theoretical framework and practical insights for understanding the policy effects of CET. However, limitations such as data confined to Chinese pilots and model simplifications remain. Future research should expand data dimensions, allowing researchers to more comprehensively evaluate policy outcomes. Full article
