GUANGZHOU, Dec. 31 (Xinhua) -- Carbon emissions allowances closed at 39.9 yuan (5.68 U.S. dollars) per tonne on Wednesday, 7.06 percent up from last transaction day at Guangzhou Emissions Exchange.
A total of 152,356 tonnes of allowances were transacted on Wednesday with a turnover of 5.4 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 233.106 million tonnes of GDEA, with a total turnover of 6.782 billion yuan. Enditem
