奥巴马呼吁发展中国家减少温室气体排放

U.S. President Barack Obama says the United States will urge emerging economies to do more to address global warming at a high-level climate change conference later this month in Durban, South Africa.President Obama told reporters Wednesday during his visit to Australia that the Durban talks should result in reduced carbon emissions, but warned that "advanced economies can't do this alone."
 
Mr. Obama said that emerging economies "like China and India" must also "take seriously their responsibilities" in reducing emissions.President Obama acknowledged that the U.S. has not been able to pass a cap-and-trade system aimed at regulating pollution, but noted U.S. efforts at increasing fuel efficiency and exploring clean energy options. Delegates from 193 countries at the U.N.-sponsored talks, which begin on November 28, will seek to find a compromise on a new international agreement on climate change.
