Emissions of carbon dioxide, the primary cause of climate change, would be cut by 4.6 percent if eight major developing nations scrapped their energy subsidies, according to a report released yesterday by the International Energy Agency. Energy consumption in the nations, which include China, India, Indonesia, and Iran, would be reduced by 13 percent and gross domestic product would grow by 1 percent through increased economic efficiency, the report found. Meanwhile, delegates to international climate change talks being held in Bonn, Germany, are making little or no headway in hammering out details of the Kyoto treaty on climate change. Some negotiators are expressing serious doubts that the Kyoto Protocol can be made to adequately address the threat of global warming.
