EPA: Cap and trade lowers NOx in eastern U.S.

14 October 2009– The U.S. Environmental Protection Agency said in a report that a cap and trade program in 20 states and the District of Columbia has reduced smog-forming emissions of nitrogen oxides.

The report, the 2008 NOx Budget Trading Program Annual Report, said summertime NOx emissions from power plants and large industrial sources were down 62 percent compared to 2000 levels, and 75 percent lower than 1990 levels.

The report also said the reduction helped reduce smog levels by 10 to 14 percent in the region and the program contributed to improvements in air quality in 97 percent of nonattainment areas in the east, with 85 percent of them now below the smog standard.

The NOx Budget Training Program is a partnership between federal and state governments to reduce the regional transport of NOx from power plants and industry in the eastern United States. The market-based cap and trade program was created to cost-effectively reduce NOx emissions during ozone season. The program allowed facilities to choose their control options including installing control technologies, replacing existing controls with more advanced technologies, optimizing existing controls and switching fuels.
