There are two schools of thought about China’s role in climate negotiations since Copenhagen. The first sees China as the principal obstacle to progress at the talks. The second considers that, as a developing country, China has done far more than its fair share. Proponents  of this view point to China’s booming renewable energy sector, which is driving the cost of technology down rapidly. A recent report  suggests that the argument may be decided in favour of the latter view. It was reported that the Ministry of Finance is now actively considering the implementation of a carbon tax in China within the period of the 12th Five Year Plan, which begins next year. This follows extensive study and modelling of the implications of such a levy for China by the government affiliated Energy Research Institute .
