Mobile engines burn fuel and generate air pollution that impacts the air we breathe.  The U.S. government is responsible for regulating mobile sources .  The DEQ Air Quality Division encourages public awareness and promotes emission reductions through clean air choices. Pollutants Mobile source engines produce air pollutants through combustion or evaporation.  Key pollutants produced include:   Carbon Monoxide  , Hydrocarbons  , Nitrogen Oxides , Particulate Matter , Air toxics  including Diesel exhaust , and Greenhouse gases .

Voluntary Programs

Smartways
A collaboration between U.S. EPA and the freight industry to increase energy efficiency, reduce greenhouse gases and air pollution

Clean Cities
A locally-based government and industry partnership, coordinated by the U.S. Department of Energy ( DOE ) to expand the use of alternatives to gasoline and diesel fuel

Action Programs
Includes programs that seek to reduce specific pollutants by a variety of individual actions.  These include self-subscribe notification programs.

Clean School Bus USA
A program from U.S. EPA to reduce children's exposure to diesel exhaust and the amount of air pollution created by diesel school buses.  Since 2004, several Michigan schools have used grants from the Clean School Bus USA program to reduce diesel emissions from their fleets.  More information  is available on these efforts.

Midwest Clean Diesel Initiative  and Retrofits
The Midwest Clean Diesel Initiative is a collaboration of federal, state and local agencies, along with communities, non-profit organizations and private companies working together to reduce emissions from diesel engines in the Midwest.

National Clean Diesel Campaign
A U.S. EPA program to reduce the pollution emitted from diesel engines across the country through the implementation of varied control strategies and the aggressive involvement of national, state, and local partners.

Voluntary Diesel Retrofit Program
A U.S. EPA effort to address pollution from diesel construction equipment and heavy duty vehicles currently on the road

Detroit Air Toxics Initiative

Vehicles and Equipment

On-road vehicles and Engines (e.g. cars and trucks)
     Heavy Trucks, Buses , and Engines and their emissions  

Non-road  (e.g., marine sources, construction equipment, farm, lawn and garden equipment)

V.  Transportation Planning

Conformity
Under the 1990 Clean Air Act Amendments, the U.S. Department of Transportation cannot fund, authorize, or approve Federal actions to support programs or projects which are not first found to conform to the Clean Air Act requirements. The FHWA and the FTA jointly make conformity determinations.

Congestion Mitigation and Air Quality
This program, jointly administered by the FHWA and the Federal Transit Administration, provides funds to state and local agencies and organizations to invest in projects that reduce criteria air pollutants from transportation-related sources.  The AQD is part of a collaborative effort along with MDOT and the U.S. EPA and FHWA.

State and Local Resources
Useful information, tools and links to resources that identify emission reduction strategies, national policies, regulations, incentive-based programs, funding sources, calculators and other assistance.

It all adds up to cleaner air!
