Yet the third report by the Intergovernmental Panel on Climate Change (IPCC) says that current measures in place are not adequate to deal with rising world temperatures.
Although not a policy report, the investigation - put together by around 2,000 UN scientists and international delegates from over 120 countries - looks at the science available to combat climate change.
It is thought that nuclear energy may be promoted by the delegates as a way of reducing climate change, a suggestion likely to meet opposition from some environmentalists.
However attempts by China to play down the language used to describe the environmental problems facing the world largely failed as a deal was met. One of the world's biggest polluters, China attempted to raise the lowest for the concentration of carbon dioxide in the atmosphere amid fears that a crackdown on emissions would affect the country's fast-growing economic development.
"It's all done," Peter Lukey, a member of the South Africa delegation, told Associated Press news agency.
"Everything we wanted to see was there and more. The message is: We have to do something now."
