Pollution Prevention

While the ground freight transportation system is invaluable to businesses, consumers, and the economy, these economic benefits are not without costs.

The U.S. EPA estimates that long duration idling consumes over one billion gallons of diesel fuel annually, at a cost of over $2.5 billion. Further, idling creates air pollution, increases engine operation and maintenance costs, and shortens engine life. Idling emissions can also leak into the truck's cab which can create health and safety concerns for the truck driver. When trucks idle near residential neighborhoods, the pollution and noise level can also raise serious quality of life concerns.

The Voluntary Idling Program (VIP) is set up to help your company identify and eliminate unnecessary idling habits. Some VIP Partners may also decide to purchase and install idle reduction technologies such as auxiliary power units/generator sets, direct fired heaters, or automatic engine shut down/start up systems. These devices are designed to allow truck drivers to turn off their engines without sacrificing driver comfort. Purchasing and installing these devices requires an upfront investment, but significantly reduces fuel consumption and can pay for themselves in a relatively short period of time.

Use the resources below to find out how your company can decrease our nation's dependency on foreign oil, reduce fuel costs, engine wear and maintenance costs, harmful tailpipe emissions, and noise.

  • DieselWise Idle Reduction Alternatives:
    • There are many alternatives to engine idling and they range from no-cost options to options costing several thousand dollars. Much depends on the extent of the idling problem and the ability to convince the truck operator to adopt the alternative.
  • U.S. EPA Diesel Emissions Reduction Grants and Loans:
    • Since 2008, EPA has funded nearly 60,000 pieces of clean diesel technology through the National Clean Diesel Campaign. These technologies include emissions and idle control devices, aerodynamic equipment, engine and vehicle replacements, and alternative fuel options. The projects meet critical local air quality needs by deploying both proven and emerging technologies much earlier than would otherwise occur.
