Carbon-trading market will be rolled out nationwide following successful pilot

China has already become the second-largest carbon-trading market in the world, and many companies have positive attitudes about the launch of the national market in 2017, a study from the UN development department found.

Since 2013, China has established pilot regional carbon-trading markets in Beijing, Shanghai, Tianjin, Shenzhen, Chongqing, Hubei province and Guangdong province, involving 2,391 companies, said the China Carbon Market Report 2017, released by the United Nations Development Program on Friday.
