Reducing Emissions of Hazardous Air Pollutants

EPA and its regulatory partners at the State and local level have taken significant steps to dramatically reduce toxic air pollutants and provide important health protections for Americans nationwide. These steps include: reducing toxic emissions from industrial sources; reducing emissions from vehicles and engines through new stringent emission standards and cleaner burning gasoline; and addressing indoor air pollution though voluntary programs. See further details on this page about reductions from:

• Industrial sources 
• Mobile sources, e.g., cars, trucks and construction equipment
