Our economy depends on trucks, trains and ships powered primarily by diesel fuel to move our food, household goods and other commodities in a constant flow throughout California. Unfortunately, freight commerce takes a toll on our health and environment when heavy-duty engines leave noxious fumes in their wake.

The California Air Resources Board (ARB) yesterday announced that the results of a new study show that the state’s regulations to control diesel engine emissions are also benefitting climate change efforts.
The project was led by Dr. Veerabhadran Ramanathan of the Scripps Institution of Oceanography at the University of California, San Diego, in conjunction with the U.S. Department of Energy’s Lawrence Berkeley National Laboratory and Pacific Northwest National Laboratory. The study estimated that the black carbon reductions from air regulations also reduced carbon dioxide emissions by 21 million metric tons annually. That’s equivalent to removing more than 4 million cars from California’s roads every year.
