Title of Chart: Impact of Control Programs on Nonroad Carbon Monoxide Emissions
Carbon monoxide emissions from nonroad sources were 10,596,597 tons in 1970. In 2000 carbon monoxide emissions from nonroad sources were 24,659,483 tons. Without regulations and technological advances, they would have been 37,373,224 tons. Carbon monoxide emissions from nonroad sources are estimated to be 34,827,986 in 2020, compared with 39,925,168 tons estimated without controls.

Title of Chart: Impact of Control Programs on Nonroad Hydrocarbon Emissions
Hydrocarbon emissions from nonroad sources were 1,676,992 tons in 1970. In 2000 hydrocarbon emissions from nonroad sources were 3,078,000 tons. Without regulations and technological advances, they would have been 3,848,662 tons. Hydrocarbon emissions from nonroad sources are estimated to be 2,146,438 in 2020, compared with 5,496,714 tons estimated without controls.

Title of Chart: Impact of Control Programs on Nonroad Nitrogen Oxide Emissions
Nitrogen oxide emissions from nonroad sources were 665,698 tons in 1970. In 2000 nitrogen oxide emissions from nonroad sources were 3,047,249 tons. Without regulations and technological advances, they would have been 3,404,910 tons. Nitrogen oxide emissions from nonroad sources are estimated to be 2,389,948 in 2020, compared with 5,328,070 tons estimated without controls.
