Diesel Technology Forum Statement On Action by the International Agency on Research for Cancer
Created:
A discussion regarding diesel fuels and emissions
In a special presentation on May 24, 2012 to the California Air Resource Board (ARB) in Sacramento, California, leading international scientists discussed the key short-lived agents black carbon (soot) and methane. Findings presented to the ARB indicated a 50 percent reduction of black carbon in ambient air over the past 20 years.
In its March 2012 Report to Congress on Black Carbon (BC), the U.S. Environmental Protection Agency (EPA) stated: “[T]he United States will achieve substantial BC emissions reductions by 2030, largely due to controls on new mobile diesel engines." The EPA report also recognizes the challenges in reducing emissions from both mobile and stationary diesel engines in these developing countries since they typically do not have ready access to cleaner low sulfur fuels that are required for most advanced emissions control technologies.
New research released April 23, 2012 from North Carolina State University - “Real-World Measurement and Evaluation of Heavy Duty Truck Duty Cycles, Fuels, and Emission Control Technologies” - shows that federal requirements governing diesel engines of new tractor trailer trucks have resulted in major cuts in emissions of particulate matter (PM) and nitrogen oxides (NOx). Trucks in compliance with newer standards showed a 98 percent decrease in NOx and 94 percent reduction in PM emissions.
