Substantial step taken to clean up environment and save energy, report Jiang Xueqing and Chen Hong in Shenzhen, Guangdong province.

On July 18, one month after China launched its first pilot carbon-trading program in Shenzhen, Guangdong province, the city began consulting local businesses and government departments about its draft regulations for the project. The regulations emphasize that carbon credits are corporate assets.

The launch ceremony of the Shenzhen Emissions Trading Scheme saw Shenzhen Energy Group sell 10,000 metric tons of carbon credits to PetroChina International Guangdong at 28 yuan ($4.60) per ton. Hanergy Holding Group also bought 10,000 tons at 30 yuan per ton. Both businesses purchased the credits for investment purposes.
