Analysis of Strategies for Reducing Multiple Emissions from Power Plants:
Sulfur Dioxide, Nitrogen Oxides, and Carbon Dioxide

Table 3. 1990 and 1997 Emissions Levels and Assumed Emission Caps for Electricity Generators

Target	NO_x (Thousand Tons)	SO₂ (Thousand Tons)	CO₂ (Million Metric Tons Carbon Equivalent)	Hg (Tons)
1990 Level	6,663	15,909	475	50
1997 Level	6,191	13,090	533	50
Emission Caps	1,548	3,273	440^a	5
^aThe integrated 2005 and integrated 2008 cases set CO₂ emissions to the 1990 levels. Source: 1997 levels from U.S. Environmental Protection Agency, National Air Pollutant Emission Trends, 1900-1998, EPA-454/R-00-002 (Washington, DC, March 2000).
