GUANGZHOU, July 9 (Xinhua) -- Carbon emissions allowances closed at 38.1 yuan (about 5.6 U.S. dollars) per tonne on Thursday, remaining unchanged from the last transaction day at the Guangzhou Emissions Exchange.
A total of 100,151 tonnes of allowances were transacted on Thursday with a turnover of 3,835,753.15 yuan.
The allowances, officially known as Guangdong Emissions Allowances (GDEA), are carbon dioxide emission 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 234.37 million tonnes of GDEA, with a total turnover of 6.83 billion yuan. ■
