Last week in Vientiane, Laos, the United States signed a climate technology-sharing pact with China, India, and Australia. The agreement, which seeks to "complement the Kyoto Protocol," brings together for the first time major carbon emitters with top developing nations to share research from coal technology to geothermal energy.
The agreement will promote technologies to provide "clean, affordable, and secure" energy, the U.S. said in a statement, and Intergovernmental Panel on Climate Change chair Rajendra K. Pachauri welcomed the news. But critics attacked the agreement, also signed by Japan and South Korea, as toothless and undercutting Kyoto.
