China: Rich nations must cut emissions by 40%

SHANGHAI -- Wealthy nations, as history's biggest polluters, should cut greenhouse gas emissions by 40% from 1990 levels by 2020, China says in a policy document on climate change. The government also rolled out fresh help for solar power and other "green energy."

The reductions China is calling for are based on the principles of "historical responsibility and fairness," the position paper says, and set a hard line ahead of international negotiations on addressing global warming.

A U.N. conference set for December in Copenhagen aims to draft a new agreement on controlling carbon dioxide and other heat-trapping greenhouse gases that scientists say are causing the Earth to warm. Delegates will meet in Bonn, Germany, next month to begin discussing the text of that agreement.

China's position paper was posted Thursday on the website of the National Development and Planning Commission, the country's main economic planning agency.

Meanwhile, the government announced new support for solar and wind power and other renewable energy sources.

In a meeting Thursday with provincial officials, the Ministry of Finance promised 38 billion yuan ($5.6 billion) in subsidies to promote wider use of wind and solar power and encourage the use of energy efficient cars and appliances, state-run media reported Friday.

China, which relies on heavily polluting coal for about three-quarters of its electricity, has sought to spotlight its efforts to improve energy efficiency and cut emissions, but has not committed to specific targets in climate talks.

The policy document issued this week gave no specific targets for China or other developing countries, but instead reiterated demands for technology transfers and other support.

Rich countries should provide at least 0.5% to 1% of their annual gross domestic product to help developing countries upgrade technology, cut emissions and adapt to the consequences of climate change, the document said.

China has welcomed President Obama's commitment to tackle climate change and re-engage in the international negotiations to come to an agreement in December.
