In 2017, the People’s Republic of China (hereafter, “China”) decided to implement a national emissions trading scheme (ETS) to limit and reduce CO2 emissions in a cost-effective manner. Set to start in 2020, the ETS will initially cover coal- and gas-fired power plants. It will allocate allowances (also known as permits), based on the plant’s generation output, with a different benchmark for each fuel and technology. China’s ETS, set to expand to seven other sectors, will be the world’s largest by far, covering one-seventh of global CO2 emissions from fossil-fuel combustion.
