U.S. and state government agencies have begun work on the next set of CAFE and greenhouse-gas standards. The NHTSA (National Highway Transportation Administration) unit of the U.S. Department of Transportation and the U.S. EPA expect to issue a final rule on MY2017-2025 standards within a year. Working with those two federal units is CARB (California Air Resources Board). The three public entities already have held meetings with automakers, suppliers, and other affected parties for their input about what technologies will be available in those years and about how much more stringent the next phase of the so-called National Program for light vehicles should be. At several points on the road to final approval, the U.S. government agencies will seek comment from the public. Comment is being sought now on work done to date. Information on that work, and how to comment on it, is located here. Comments are due Oct. 31.
