EPA’s Clean Agriculture is an innovative program to help farmers, ranchers, and agribusinesses reduce emissions from older diesel engines currently in use. Because these engines can last 20 to 30 years and are not subject to EPA’s emissions standards for new diesel engines, they will continue to emit harmful pollutants until they are retired.

Reducing exposure to diesel exhaust is important for public health and the environment. Clean Agriculture provides fleet managers, equipment owner and operators, and farmers a variety of strategies for reducing emissions, including idle-reduction practices that save money while reducing fuel consumption and emissions.

In addition, EPA offers funding for diesel emission reduction programs. In January 2011, President Obama signed legislation reauthorizing DERA funding to eligible entities for projects that reduce emissions from existing diesel engines. Appropriations are determined by Congress on an annual basis.
