China called on developed nations on to devote 1% of their GDP to assisting developing nations in the fight against global warming on Tuesday, Reuters reported. Much of the money would be spent on the transfer of "green" technologies, said Gao Guangsheng, head of the National Development and Reform Commission’s climate change office. The announcement comes ahead of UN talks due to take place in Poland in December at which negotiations will continue over a successor to the Kyoto protocol, the main provisions of which expire in 2012. China will detail its policies on climate change in an official white paper to be released on Wednesday. Separately, China defended its energy policy following claims in a report by Greenpeace, the Energy Foundation and the World Wildlife Fund that the country’s coal dependency is creating hidden environmental and other costs worth more than 7% of its GDP.
