Under the "dual carbon" goals, green finance, as a financial activity aimed at optimizing resource allocation and protecting the environment, holds significant scientific importance for the rational adjustment and upgrading of regional industrial structures. Hebei Province, a key industrial hub in China, faces an urgent need for industrial structure adjustment and optimization. This paper employs time series data from Hebei Province spanning 2001 to 2023 to measure the development levels of green finance and industrial structure, and constructs a coupling coordination model to analyze their interactions. Furthermore, the study uses the GM (1,1) grey model to predict future trends. The results indicate that the coupling coordination degree between green finance and industrial structure upgrading in Hebei Province has steadily improved but remains at a moderate coupling stage. It is projected that the coupling coordination degree will continue to rise, entering a high coordination stage by 2032.

The development of green skills has gained significant attention in recent years, driven by the increasing global focus on achieving the Agenda 2030 goals and the United Nations Sustainable Development Goals (SDGs). Green skills are recognized as essential for fostering sustainable practices across industries, supporting the transition to a low-carbon economy, and addressing pressing environmental challenges. A notable surge in scholarly interest is observed, with 79% of publications related to "green skills development" in the Web of Science database being published after 2015. This indicates the growing recognition of green skills as a key element in advancing sustainability agendas. In this study, a bibliometric analysis was conducted using data from 962 articles extracted from the Web of Science database. The evolution of scientific output, thematic trends, and international collaboration patterns were examined. The analysis reveals a steady increase in publications, particularly post-2015, with an expanding range of research topics, including renewable energy, energy efficiency, green entrepreneurship, and climate adaptation. The distribution of authorship across countries highlights significant international cooperation, with countries from both the Global North and South actively contributing to the discourse. The findings underscore the interdisciplinary nature of green skills research, which spans diverse fields such as environmental science, education, policy studies, and technology. Moreover, the growing body of research reflects a clear shift towards integrating green skills within education and training systems as a means of achieving SDG targets, particularly those related to sustainable economic growth, decent work, and climate action. This study provides valuable insights into the emerging trends and collaborative networks in green skills development, offering a foundation for future research aimed at enhancing the effectiveness of green skill programs and policies. It is evident that continued focus on this area is critical for driving global sustainability efforts and achieving long-term environmental goals.

Solid waste management in rural areas remains an underexplored domain, despite its growing significance in the context of environmental sustainability and the circular economy. Key challenges include inadequate municipal infrastructure, a shortage of waste collection containers, and the absence of suitable vehicle fleets capable of navigating narrow and steep rural pathways. Moreover, the lack of a strategic framework for waste management, the insufficient application of the 3R (Reduce, Reuse, Recycle) principles, and the absence of circular economy practices further exacerbate these issues. In rural areas, approximately 40% of the waste produced is organic and could be used as a resource for compost production, a valuable input for organic agricultural practices. Projections suggest that by 2027, biowaste will account for 8% of the total waste generated in rural communities. The transition to a circular economy offers significant potential for transforming waste management practices in these areas. Emphasis on innovative collection methods, such as localised and adaptive waste separation techniques, can facilitate this transition. The adoption of circular economy principles in waste management strategies is critical, not only for reducing environmental impact but also for promoting resource efficiency, enhancing soil fertility, and supporting sustainable local economies. Raising public awareness, engaging local communities, and introducing more effective waste management systems will be vital in overcoming existing barriers and ensuring the success of these initiatives.

In light of the intricate interconnection of current global challenges, energy security concerns, and global warming, the strategic pursuit of renewable hydrogen has emerged as a beacon of promise. Consequently, Canada, in alignment with its global environmental commitments and supported by partnerships with entities such as the European Union, is actively working to harness its significant potential in sustainable hydrogen production and distribution. This study undertakes a systematic review and bibliometric analysis of 55 scientific papers focused on hydrogen production and distribution in Canada, published up to September 2023. Firstly, a comprehensive synthesis of these papers is provided across four key dimensions: production, distribution, optimization, and sustainability. Secondly, critical insights into the evolution of hydrogen research and the collaborations shaping the field are unveiled through bibliometric analysis, employing Bibliometrix, an R-package designed for comprehensive science mapping and bibliometric analysis. The findings are intended to offer valuable insights to academic, public, and business communities, enabling them to better utilize available resources, enhance teamwork, and contribute to a more sustainable global energy landscape.

The development of green farmhouse technology is crucial for advancing sustainable agricultural practices in China. However, the comprehensive promotion and effective implementation of green farmhouse construction are significantly hindered by the underdevelopment and immaturity of the required technologies. This study aims to identify and analyze the key factors that impede the development of green farmhouse technology and to elucidate the interrelationships among these factors. A systematic literature review was conducted to determine the primary barriers to green farmhouse technology development. The Decision-Making Trial and Evaluation Laboratory (DEMATEL) method was employed to examine the interdependencies among these factors, providing insight into their mutual influence and centrality. Subsequently, Interpretive Structural Modeling (ISM) was applied to establish a hierarchical structure, revealing the multi-level relationships among the identified barriers. Finally, the Multiplication of Cross-Impact Matrices (MICMAC) analysis was utilized to further categorize the factors based on their driving power and dependence. The findings indicate that the development of green building materials, research and development (R&D) funding, and technological expertise are the core factors impeding the advancement of green farmhouse technology. These barriers were classified into six hierarchical levels and grouped into four categories: autonomous, dependent, linked, and independent factors. Through the combined application of DEMATEL, ISM, and MICMAC, a comprehensive understanding of the hierarchical structure and the interrelationships among these barriers was achieved. The factors were further categorized into three groups: budget and funding constraints, green farmhouse technology R&D challenges, and technology promotion and selection obstacles. The insights derived from this study provide a theoretical foundation for developing strategies to overcome these impediments, thereby facilitating the broader adoption of green farmhouse technology in China.
