The People’s Republic of China (PRC) launched seven emissions trading scheme (ETS) pilot projects in 2013–2014 to explore a cost-effective approach for low-carbon development. The central government subsequently announced its plans for the full-fledged implementation of ETS in the entire PRC in late 2017. To ensure the success of ETS in the PRC, it is necessary to gain a better understanding of the experiences and lessons learned in the pilot projects.
