Washington, D.C. – The U.S. Environmental Protection Agency (EPA) has awarded $50 million for clean diesel projects as part of an ongoing campaign to reduce harmful emissions and better protect people’s health.

These efforts will replace, retrofit or repower more than 8,000 older school buses, trucks, locomotives, vessels and other diesel-powered machines.

The EPA said that diesel engines emit 7.3 million tons of smog-forming nitrogen oxides (NOx) and 333,000 tons of soot annually, and pollution from them is linked to premature deaths and asthma attacks. While the EPA’s standards significantly reduce emissions from newly-manufactured engines, clean diesel projects funded through these grants will work to address the more than 11 million older diesel engines that continue to emit higher levels of harmful pollution.

From 2008 to 2010, the EPA has awarded nearly $470 million to more than 350 projects across the U.S. under the diesel emissions reduction program. The projects have cleaned or replaced more than 50,000 vehicles and equipment nationwide.
