Climate China
In this photo taken March 8, 2010, a power station technician walks past a steam-turbine power generator in the Waigaoqiao No. 3 power station in Shanghai, China. China told the United States on Wednesday to make stronger commitments on climate change and provide environmental expertise and financing to developing nations. China, the world's largest emitter of heat-trapping greenhouse gases, has said it will cut its "carbon intensity" _ a measure of carbon dioxide emissions per unit of production _ by 40 percent to 45 percent by 2020, compared with 2005 levels.
