A Smart Clean Air Investment

The Diesel Emissions Reduction Act (DERA) establishes a voluntary national and state-level grant and loan program to reduce emissions from existing diesel engines through clean diesel retrofits.  Emissions from older diesel vehicles and equipment can be reduced betweent 20 and 90 percent with cost-effective retrofit technology.  The EPA estimates that if DERA is fully funded, it would reduce particulate matter emissions by 70,000 tons, generate nearly $20 billion in economic benefit, and return $13 of benefit for every one dollar invested.

Since the program's creation in 2005, the U.S. EPA has provided $464.9 million in grants for diesel retrofit projects. For more information about the program’s structure and funding priorities, view the full DERA fact sheet here.
