GUANGZHOU, April 17 (Xinhua) -- Carbon emissions allowances closed at 38.50 yuan (5.64 U.S. dollars) per tonne on Friday, 0.26 percent up from last transaction day at Guangzhou Emissions Exchange.
A total of 590 tonnes of allowances were transacted on Friday with a turnover of 22,715.57 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 233.512 million tonnes of GDEA, with a total turnover of 6.798 billion yuan. Enditem
