The U.S. National Highway Traffic Safety Administration and the Environmental Protection Agency won’t be working alone with it comes to developing new greenhouse emissions standards ordered Tuesday by the Obama Administration.
They will be relying, at least partially, on work already done by California and its Air Resources Board, according to a release form the agency.
California assumed a leadership role in regulating GHG emissions with passage of The Global Warming Solutions Act in 2006 by state lawmakers. In 2011, the federal Phase 1 greenhouse gas standards for heavy-duty vehicles were approved nationally. As part of its climate and air quality improvement programs, California aligned its heavy-duty vehicle requirements with those regulations in 2013.
“We look forward to teaming with the federal agencies and strongly support this effort. We are excited to share the California experience and technical expertise gained from our early actions to reduce emissions and save fuel from the heaviest trucks via our California tractor-trailer greenhouse gas program over the last six years,” said Air Resources Board chairman Mary D. Nichols. “The Phase 1 standards that are already in place will reduce these emissions by about 10%, and we look forward to developing more ambitious Phase 2 regulations to provide even greater benefits.”
CARB said it believes the collaborative work with U.S. EPA and NHTSA will build on the its experience with reducing emissions from diesel trucks and buses which have already reduced black carbon, a powerful greenhouse contaminant, by 90% in the state.
“The federal Phase 1 standards required more efficient engines, use of low rolling resistance tires, reduced idling and aerodynamic improvements,” CARB said. “The Phase 2 standards are expected to prompt even more innovation, improvements and significant fuel savings for the end-user.”
