In May 2002, New Hampshire became the first state in the country to adopt rules to regulate carbon dioxide (CO2) emissions from power plants. The new law establishes a multiple pollutant reduction program. In addition to CO2, the final version of the new law (HB284, NH Laws of 2002, Chapter 130) establishes caps on emissions of sulfur dioxide and nitrogen oxides by existing fossil fuel electric power plants and also requires a reduction in mercury pollution. This law permits the banking and trading of emissions reductions credits to achieve compliance with the caps. The NH Department of Environmental Services is directed to establish an integrated strategy to reduce emissions, including the use of energy efficiency and renewable energy. The new law went into effect July 1, 2002.
