ReturnGUANGZHOU, Feb. 21 (Xinhua) -- Carbon emissions allowances closed at 77.46 yuan (11.29 U.S. dollars) per tonne on Tuesday, 0.26 percent up from Monday, at Guangzhou Emissions Exchange, the largest local carbon market in China.
A total of 75,000 tonnes of allowances were transacted on Tuesday, with a turnover of 5.809 million yuan.
The allowances, officially known as Guangdong Emissions Allowances (GDEA), are carbon dioxide emissions caps assigned to companies. Firms whose emissions surpass their share must buy extra quotas from authorities or purchase unused quotas on the market from those that cause less pollution.
Since its opening in December 2013, the market has traded 214.935 million tonnes of GDEA, with a total turnover of 5.687 billion yuan.
