Green Fleets

The Kentucky Department for Environmental Protection (DEP) operates a fleet of 24 light-duty hybrid electric vehicles and the first plug-in electric vehicles (PEV) in state government.  By strategically managing its fleet, DEP now operates fewer conventional vehicles and drives a larger percentage of "green" miles. DEP has "right-sized" its sport utility vehicle (SUV) fleet by replacing full-size and mid-size SUVs with more compact SUVs. 

DEP is a pioneering member of the Green Fleets of the Bluegrass program. Green Fleets of the Bluegrass aims to improve the environmental performance of vehicle fleets across Kentucky by reducing petroleum fuel use. As part of their Green Fleet efforts, DEP strives to reduce fuel use and improve performance of its fleet, which in turn leads to fewer dollars spent on fuel and fewer tail pipe emissions. Efforts include downsizing to the smallest and most fuel-efficient class possible for replacement vehicles as well as taking advantage of hybrid efficiencies. In addition to active membership in the Kentucky Clean Fuels Coalition, DEP is also working to promote fleet efficiencies among other state departments across Kentucky.

Future best practices that DEP is currently evaluating include:
  • Adopting an idle-reduction policy
  • Establishing a renewable fuel standard for the fleet
  • Improving maintenance of the fleet
  • Education and outreach on the Green Fleet program.
