Fleets

What roles do fleets play in protecting air quality?

As a fleet owner or manager, you have many opportunities to help improve air quality. By the year 2007, mobile sources will contribute more than 60 percent of Tennessee’s nitrogen oxide (NOx) emissions, one of the key pollutants that create ozone. Heavy-duty diesel engines also create fine particle pollution (PM2.5). Reducing the air pollutants emitted from your company’s vehicles will help reduce harmful levels of ozone and fine particle pollution in Tennessee.

What can I do to reduce air pollution?

Regardless of the types of vehicles you drive or the size of your fleet, you can take action to reduce your organization’s vehicle emissions.

Adopt policies to reduce unnecessary idling

Take action to improve fuel efficiency, including reducing highway speeds

Use cleaner fuels whenever possible

Purchase new vehicles with cleaner, more fuel-efficient engines or install diesel retrofit technologies to reduce air emissions

Participate in EPA’s SmartWay Transport Partnership program (for diesel fleets)

The federal Energy Policy Act of 1992 (EPAct) aims to reduce our nation's dependence on imported petroleum by requiring certain fleets to acquire alternative fuel vehicles, which are capable of operating on nonpetroleum fuels.
