New-generation diesel engines deliver national clean air benefits and fuel savings, EPA report says

Since 2008, 67,300 older diesel-powered engines have been upgraded or replaced thanks to funding provided by the Diesel Emission Reduction Act (DERA), resulting in major clean air benefits and fuel savings, according a new report issued July 26 – “DERA Fourth Report to Congress: Highlights of the Diesel Emissions Reduction Program” by the U.S. Environmental Protection Agency (EPA).

According to the report, 472,700 tons of nitrogen oxides (NOx), 15,490 tons of particulate matter (PM), and 5.1 million tons of carbon dioxide (CO2) were reduced and 454 million gallons of fuel were saved between 2008 and 2016, due to the replacement or upgrading of older diesel engines with newer, cleaner technologies. These reductions resulted in $19 billion in public environmental benefits for $629 million invested by Congress, according to the Diesel Technology Forum.
