Climate change chief puts China carbon tax into question
The statement contrasts with earlier media reports saying China will introduce a tax before 2015 and underscores global interest in how China plans to address climate change in the years ahead, according to a report in Reuters.
Speaking at the World Resources Institute in Washington, Su Wei, China's chief negotiator on climate change, said a tax on carbon was one of several policy options for China to reduce its greenhouse gas emissions, the highest of any nation.
But China plans to launch a carbon trading scheme, and adding a tax on major emitters could complicate legislation.
"There may be some overlap between the two systems. Of course, the two systems are not mutually exclusive. We need to have a very careful consideration," Su told reporters at WRI, an international think tank.
A decision on a carbon tax would be delayed until there was clarity on whether and how the two instruments could co-exist.
Chinese state media reported last week that a government-affiliated think-tank, the Financial Science Research Institute, had proposed to the Ministry of Finance that China implement a 10 yuan (USD1.58) per tonne tax on emissions from big energy users before 2015.
