Dear Administrator Jackson: 

The State of California’s Air Resources Board (ARB) strongly supports the recently 

announced United States Environmental Protection Agency (U.S. EPA) and National 

Highway Traffic Safety Administration (NHTSA) proposed national program to reduce 

greenhouse gas (GHG) emissions and improve fuel efficiency of medium- and heavyduty vehicles. Continued, unwavering progress along this regulatory path is vital for 

California and the nation as we continue to strive to stabilize the climate and address 

the threat of global climate change. 

California appreciates your staff’s engagement with ARB to date and understands that 

this program would result in the introduction of the most GHG-efficient medium- and 

heavy-duty vehicles on the road, encouraging technology innovation and early 

introduction. California fully supports the development of such national regulations, as it 

will help us meet the goals established by the California Global Warming Solutions Act 

of 2006 (AB 32). Specifically, AB 32 mandates a reduction of California's GHG 

emissions to 1990 levels by 2020 and the Governor has ordered an 80 percent 

reduction from 1990 levels by 2050. 

In order to meet these aggressive goals, California has already taken action. In 

December 2008, ARB adopted the Heavy-Duty Vehicle Greenhouse Gas Emission 

Reduction Regulation requiring the use of U.S. EPA SmartWay certified heavy-duty 

tractor trailer combinations in California. While California is committed to the success 

of our program, we are encouraged and have welcomed the opportunity to partner with 

U.S. EPA and NHTSA on a national program. 
Honorable Lisa P. Jackson, Administrator

Such a partnership would better achieve our shared goals and provide national 

consistency for the regulated community. We look forward to continuing our work with 

U.S. EPA and NHTSA on this program. Should you have any questions, please contact 

Mr. James Goldstene, Executive Officer, at (916) 445-4383 or at jgoldste@arb.ca.gov. 

Sincerely, 

Mary D. Nichols 

Chairman
