Yesterday, the House subcommittee on Energy and Air Quality held a hearing on climate change. The group discussed the role developing countries will play in climate change legislation that is developed by United States. One goal is to develop legislation that will encourage China and India to limit their emissions. Energy and Commerce Committee chairman John Dingle said, "This is one of the most difficult issues Congress faces in crafting climate change legislation." The challenge for Congress is to pass a law that will also withstand objections from the World Trade Organization (WTO). Representatives Upton and Boucher believe including language that calls for China, India and other developing countries to limit their emissions should be mandatory in the legislation that the United States will attempt to pass.
