Progress on Emissions and Acid Rain
January 27, 2012 |

“Since the establishment of the Acid Rain Program, of the 1990 Clean Air Act Amendments, there have been substantial reductions in sulfur dioxide and nitrogen oxides emissions from power plants that use fossil fuels, which are known to be the primary causes of acid rain. As of 2009, emissions of SO2 and NOx declined by about two-thirds relative to levels in the 1990s.” Quoted from the USGS press release.
