Green<br />Statement


The Association of Diesel Specialists (ADS) believes in the future of clean diesel as part of an environmental solution to global greenhouse gas issues. ADS believes in the future of the inherently more efficient clean diesel power plant as a method of reducing our dependence on fossil fuels. ADS applauds the work of engine manufacturers in their efforts to continuously reduce emissions in diesel engines to near infinitesimal levels. ADS believes that the use of clean diesel will improve the sustainability of consumers, businesses and communities by reducing the environmental and societal cost of their activities.
ADS does not condone the use of devices made to intentionally contravene emission controls for use in equipment or vehicles used on a regular basis. ADS believes that intentionally bypassing or altering emission controls in the name of performance enhancement undermines individual and group efforts to promote the use of clean diesel as a viable alternative power plant for the future.
