Air Resources Board teaming with U.S. EPA and NHTSA to develop
next generation of heavy duty vehicle greenhouse gas standards

Joint California-federal effort will assist California’s
greenhouse gas reduction efforts and help industry with one
national standard

Sacramento — The Air Resources Board today hailed NHTSA and U.S.
EPA’s announcement of the development of a next phase of
greenhouse gas (GHG) standards for heavy duty vehicles. The
federal agencies have announced they will begin their rulemaking
process on regulations, known as the Phase 2 standards, which
require further reductions in GHG emissions and corresponding
higher efficiency standards from vehicles ranging from heavy
pick-up trucks to tractor-trailers weighing more than 33,000

“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 percent, and we look forward
to developing more ambitious Phase 2 regulations to provide even
greater benefits.”

California assumed a leadership role in regulating GHG emissions
with passage of The Global Warming Solutions Act (AB 32) in 2006.
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

And now, ARB is working with the U.S. EPA and the U.S. Department
of Transportation’s National Highway Traffic Safety
Administration (NHTSA) on national GHG standards and
corresponding fuel efficiency standards for medium- and
heavy-duty vehicles. The collaborative work with U.S. EPA and
NHTSA will build on the ARB’s experience with reducing emissions
from diesel trucks and buses which have already reduced black
carbon, a powerful greenhouse contaminant, by 90 percent in the

The federal Phase 1 standards required more efficient engines,
use of low rolling resistance tires, reduced idling and
aerodynamic improvements. The Phase 2 standards are expected to
prompt even more innovation, improvements and significant fuel
savings for the end-user.
