Economic Logic Exploration of Collaborative Legislation of Circular Economy and Low Carbon Economy under Double Carbon Goal

Throughout the world, the European Union, the United States, Japan, Singapore and other major developed economies have taken the development of circular economy as an important pillar and key path to drive economic growth and achieve climate goals, and have formulated a series of supporting regulations, directives and relevant action plans. In 2015, the EU adopted the EU Circular Economy Action Plan, which included the circular economy as an important strategy to tackle climate change and boost economic growth under the framework of the Europe 2020 Strategy. With the increasingly serious problem of global climate change, the realization of the dual carbon goal (carbon peak and carbon neutrality) has become the core issue of common concern of governments and global organizations. In order to achieve this goal, circular economy (CE) and low carbon economy (LCE), as two important development concepts, are gradually paid attention to by national policies and economic fields. However, it is often difficult for a single economic model and policy to effectively promote the deep integration and coordinated development of the two. Therefore, exploring the collaborative legislation of circular economy and low-carbon economy has important theoretical and practical significance.
