The US House of Representatives has voted to extend the Diesel Emissions Reduction Act (DERA) through 2029. The bipartisan measure, passed with a 343-79 vote, authorizes $100 million in annual funding for the program.
House Resolution 2140 amends the Energy Policy Act of 2005 to continue the grant program. The legislation was introduced by representatives Doris Matsui, Ken Calvert, Chellie Pingree, and Nick Langworthy.
Administered by the US EPA, the program provides competitive grants to help fleet operators offset the costs of transitioning from diesel-powered vehicles to cleaner alternatives. This initiative aims to reduce air pollution and fuel consumption.
Over the past 20 years, DERA has facilitated the removal of tens of thousands of engines from service and saved fleets more than 500 million gallons of fuel. The bill now moves to the Senate for further consideration.
