“Waste-free Cities”Construction and Carbon Emission Reduction in China:Based on the Perspective of Circular Economy

Solid waste and carbon dioxide are important elements of environmental governance.Under the background of carbon peaking and carbon neutrality goals,the research on whether and how to promote the construction of“no waste cities”and carbon emission reduction is of great significance in China.The generation of solid waste and greenhouse gases such as carbon dioxide has the same origin,which can be well coordinated to promote environmental governance.

Evolving pattern and improvement path of China’s solid waste management policies

Systematically sorting out the evolving pattern of solid waste management policies and studying the key points and development trends of solid waste management policies are conducive to the clarification of improvement path of solid waste management policies.Based on the promulgated solid waste management policies,this study applies statistical methods to the analysis of the text structure and contents of the solid waste management policies,attempting to find out the internal evolving pattern of the solid waste management policies in China.Closely integrating the current policy requirements for the construction of‘waste-free city’,this study puts forward a policy optimization and improvement path.The findings are briefly listed blow:①The solid waste management policies have demonstrated multiple text types and various levels of effectiveness,and the policy framework system is gradually optimized.②In each edition of solid waste management policy,the hotspot issues are highlighted with distinctive characteristics of the times and dynamic evolution.The policies are covering more fields,the contents are more targeted and comprehensive,and the implementation is more specific and practical.③The policies mainly focus on harmlessness,reduction,reclamation,pollution prevention,supervision and management,secondary pollution,recycling,circular economy,etc.④The government strengthens the top-level design from the macro level,focusing on policy guidance and standardization,policy coordination,technical support,and governance improvement to promote the realization of the goals of‘harmlessness,reduction,reclamation’.⑤The diversification of tools,approaches and factors supporting solid waste management,and the growing awareness of the technical support of solid waste management,and the management mode and governance path have entered the phase of adaptive transformation.Based on practical needs,the market oriented policies and incentive mechanisms for solid waste management are inadequate,applicable technical attention is not highly paid,and the comprehensive management level and governance capabilities are in urgent need of improvement.Combined with the theoretical research,practical actions and policy initiatives of the construction of‘waste-free city’in other countries,from the perspectives of solid waste full product lifecycle management,technical support paradigm policy,main body coordination policy,guidance incentive policy,laws and regulations and other aspects,the policy improvement path and direction of China’s‘waste-free city’are thoroughly discussed in this study.
