WASHINGTON, Jan. 27, 2015 /PRNewswire/ -- The Diesel Technology Forum issued the following statement today regarding the multi-year Advanced Collaborative Emissions Study (ACES) conducted by the Health Effects Institute (HEI).
HEI conducted the independent study of new technology diesel engines to determine whether the engines achieved the expected emissions reductions, thereby improving air quality for public health, as well as whether the new technologies resulted in any unintended increases in emission components. The study concluded that exposure to new technology diesel exhaust does not cause any increase in the risk of lung cancer or other significant adverse health effects in study animals.
"The significance of this study and its conclusions cannot be overstated," said Allen Schaeffer, the Executive Director of the Diesel Technology Forum. "The results of this new study verify the environmental benefits of the new clean diesel technology, which have near-zero emissions for nitrogen oxides (NOx), hydrocarbons (HC) and particulate matter (PM). And while this study focused on heavy duty truck emissions, the new clean diesel technology has the potential for impacting all sectors, including passenger cars, agriculture, construction, maritime and transportation.
"As other countries embrace cleaner diesel fuels, they will also be able to reap the benefits of cleaner air with new clean diesel technology engines manufactured in the United States. Today, one in four advanced clean diesel engines produced here is exported internationally.
"The comprehensive nature of this study by such an authoritative body as the Health Effects Institute is extremely significant. It's also important to highlight that the U.S. Environmental Protection Agency (EPA), the California Air Resources Board, the U.S. Department of Energy (DOE) and the U.S. Federal Highway Administration are sponsors of this study in conjunction with the manufacturers of emissions control equipment."
The ACES effort has been guided by an independent Oversight Committee comprised primarily of academic scientists.
"The findings of the ACES study are extremely important because diesel engines are the technology of choice that drives 15 sectors of the global economy―from agriculture to goods movement, from construction to warehousing.
"In the U.S., clean diesel technology has reduced particulate matter and NOx emissions by 98 percent compared to 1988 vehicles. Diesel technology has undergone a complete transformation beginning with a move to ultra-low sulfur diesel fuel in 2006 that reduced the fuel's sulfur content by 97 percent. This cleaner fuel then enabled refinements in engine technology and the use of emission controls and reduction strategies that are now deployed throughout a wide range of industry, engines and technology."
