"EPA and other clean air agencies have found that black carbon emissions from a variety of sources have a short-term warming effect on the climate. New technology diesel engines used in all types of on and off-road equipment-- some of which use particulate filters and catalysts -- have reduced particulate matter to near zero levels. Diesel retrofit projects can reduce emissions of particulate matter and in turn black carbon or soot," Schaeffer said.
"In addition, in many applications, older engines may be modernized and upgraded with filters and other retrofit devices to virtually eliminate soot and/or be repowered with a new engine. The EPA report highlights that between 2008 and 2010, the DERA program helped replace, repower or retrofit almost 44,000 older engines and is expected to help reduce black carbon emissions," Schaeffer said.
Regional Clean Diesel Collaboratives Include All 50 States Since its creation in 2005, DERA has been supported by a bipartisan coalition of several hundred environmental and public health organizations, industry representatives, and state and local government associations including the American Lung Association, Natural Resources Defense Council, Environmental Defense Fund, Union of Concerned Scientists and National School Transportation Association. Together these groups continue to work together in educating Congress about these benefits and the importance of continued funding for the program.
"Thanks to DERA, not only have vehicles' emissions been reduced, but awareness about the advantages of clean diesel technology has grown exponentially," said Schaeffer. "Regional clean diesel collaboratives have been created throughout the country, bringing together vehicle and equipment owners, state and local governments and environmental advocates. As a result, today all 50 states now have some form of clean diesel retrofit program, with many of them also providing their own matching funds."
ABOUT THE DIESEL TECHNOLOGY FORUM
The Diesel Technology Forum is a non-profit national organization dedicated to raising awareness about the importance of diesel engines, fuel and technology. Forum members are leaders in clean diesel technology and represent the three key elements of the modern clean-diesel system: advanced engines, vehicles and equipment, cleaner diesel fuel and emissions-control systems.
