CLIMATE CHANGE: China and India called keys in climate change battle
2008-05-08 18:23:00 If the world is going to truly combat greenhouse gas emissions, China and India have to be part of the fight, the chief economist for the Paris-based International Energy Agency said Tuesday. Fatih Birol told oil and gas executives at the Offshore Technology Conference in Houston that the economies of China and India are growing at such a pace that they'll keep needing more energy, much of it from coal. Even if Europe cuts emissions by 20 percent in the next dozen years as pledged, it won't be enough to overcome emissions anticipated to increase in the developing giants, he said.But don't blame China, the bigger of the two, he said.China's growth is "simply imitating" what developed countries have already done. Americans love their cars, and increasingly the Chinese do as well, driving most of the increase in that country's demand.The nation is expected to overtake the U.S. in terms of car ownership in seven to eight years. And by 2030, 14 percent of Chinese will have cars, as...
