Why is EPA looking at new emission controls for off-highway motorcycles?
Our analysis shows that off-highway motorcycles emit more than 134,000 tons of hydrocarbons (HC), 181,000 tons of carbon monoxide (CO), and 1,000 tons of oxides of nitrogen (NOx) each year across the United States. These emissions help form smog and contain toxic compounds such as benzene, so reducing them would benefit our health and environment. The Clean Air Act requires us to set emission standards that address these problems. These impacts are described in more detail in “FAQ: Environmental Impacts of Recreational Vehicles and Other Nonroad Engines” [EPA420-F-01-030].
