Guidelines for a voluntary carbon trading system to be implemented in China’s Guangdong province were released by provincial officials September 11. The Guangdong carbon trading program, part of a national pilot program, will begin with 827 companies across nine industrial sectors: electricity, cement, steel, ceramics, petrochemicals, textiles, nonferrous metals, plastics, and paper. The province’s carbon trading program will have a testing period from 2012 through 2015, a period of perfect trading rules from 2016 through 2019, and a fully trading carbon market starting in 2020. Other Chinese provinces and municipalities participating in the national program, whose goal is to set up pilot emissions trading systems by the end of 2015, include Hubei, Beijing, Chongqing, Shanghai, Shenzhen, and Tianjin,
