A comparative analysis of Chinese regional climate regulation policy: ETS as an example.

An effective and powerful regulation is indispensable for the development and smooth operation of a cap-and-trade emission trading scheme (ETS). Seven regional pilot ETSs have been established and gradually improved in China, from which the experiences and lessons learned may provide useful references to facilitate China's national ETS regulation. This article systematically reviews and compares the practices and policies of carbon trading regulation in China's seven pilot schemes from three major aspects of regulatory institutions and subjects, regulatory objects and content, and regulatory means and techniques, and covering both internal and external regulatory architectures. The comparative analysis has demonstrated that the regional pilot schemes have made notable achievements in developing ETS regulatory systems with Chinese characteristics, but they still have considerable deficiencies. Referencing both international and domestic pilot experiences, this study recommends that China's national ETS improve regulatory institutional basis, foster an extensive participation of pluralistic regulatory subjects with a clear division of powers and responsibilities, establish effective regulatory systems on carbon finance, and continuously enrich regulatory techniques and platforms.
