2. DUKE ENERGY POSITION ON CLIMATE CHANGE LEGISLATION  Duke Energy Supports the Enactment of Economically and Environmentally Sustainable Federal Climate Change Cap – and - Trade Legislation  Economic Sustainability Includes Provide Adequate Consumer Price Protection  The Question of Whether GHG Regulation Is Coming Is Settled  EPA is moving to regulate – set to do so in March of 2010  Duke Energy Prefers a Legislative Approach  EPA lacks the legislative authority to craft an environmentally sound program that protects the economy and consumers  A program that can have such broad economic implications for the country’s economy should be the responsibility of an elected and accountable Congress 2
