Beijing, Nov 27: The State Council has announced to cut its intensity of Co2 emission per unit of GDP by almost 45 per cent by 2020.
The State Council said, "It is a voluntary action taken by the Chinese government based on its own national conditions and is a major contribution to the global effort in tackling climate change."
The announcements come after the White House said President Barack Obama will attend the start of the conference to personally commit the US to a goal of substantially cutting greenhouse gases.
India, the world's fifth-biggest greenhouse gas emitter, has proposed a similar policy to link emissions to growth in gross domestic product, defined as a broad measure of the value of the nation's total output of goods and services.
"This is the first time China has a target that directly links up its emissions figure and its economic development ... the importance of this figure is really that China wants to show how it's going to try to develop in a more low-carbon way," said Yang Ailun, climate campaign manager for Greenpeace China.
