California Air Resources Board applauds new  federal fuel
efficiency, greenhouse gas standards for heavy duty trucks

SACRAMENTO:  The California Air Resources Board (CARB) announced
its support of new standards finalized today by the US
Environmental Protection Agency (EPA) and the National Highway
and Traffic Safety Administration (NHTSA) that will reduce carbon
pollution and improve fuel efficiency from medium- and heavy-duty
trucks.  

The Phase 2 standards announced today will cut emissions and
improve efficiency for a wide range of vehicles, from heavy-duty
pickups to large 18-wheel tractor-trailer trucks.  They include
the first ever national standards for improved aerodynamics and
tires on big-rig trailers. California has had a GHG-reduction
regulation in place for box-type trailers 53 feet and longer
since 2010.

CARB staff worked closely with EPA and NHTSA staff over the past
several years as the standards were developed, and submitted
detailed comments on the proposed standards last October.  The
federal agencies modified their proposal to address many of
CARB’s concerns, including greater emphasis on advanced
technologies and mitigating potential increases in diesel
particulate matter. 

To meet our long-term greenhouse gas goals out to 2050,
California will need to continue to make progress, even after the
Phase 2 standards are fully implemented in 2027.  The ARB is
looking forward to continued cooperation with the federal
agencies on this long-term effort. 

In addition, CARB is looking forward to working with the federal
agencies to develop new, lower NOx standards which are critically
needed in California to clean the state’s air in time to meet
federal Clean Air Act deadlines.  In order to achieve the 2008
Ozone National Ambient Air Quality Standards set by US EPA, CARB
estimates that the South Coast Air Basin alone (including Los
Angeles) will need an 80 percent reduction in NOx emissions by
2031.

“We support this comprehensive effort by USEPA and NHTSA to cut
greenhouse gases from heavy duty trucks,” said CARB Chairman Mary
D. Nichols.  “We will continue our strong partnership with them
as we move forward together to establish nitrogen oxide standards
that will help address California’s unique air pollution
challenges.” 

Heavy-duty vehicles on California highways contribute about
one-third of all NOx emissions in the state. Because many trucks
operating in California are first purchased outside the state,
mandatory, lower federal NOx standards are crucial for
California.  In addition, 60 percent of total heavy-duty truck
miles in Southern California on any given day are driven by
trucks purchased outside of California.

Nitrogen oxide (NOX) is one of the major precursors of
tropospheric ozone (ozone), exposure to which is associated with
a number of adverse respiratory and cardiovascular effects. These
effects are particularly pronounced among children, the elderly,
and people with lung disease such as asthma.  NOX is also a major
contributor to secondary PM2.5 formation, and exposure to PM2.5
itself has been linked to a number of adverse health effects such
as heart attacks and premature mortality.  In addition, NOx
exposure is linked to asthma exacerbation and possibly to asthma
development in children.

The Golden State, long recognized as having the nation’s poorest
air quality thanks to its geography and large population of
people and vehicles, is already fighting the battle against air
pollution related to freight and heavy duty vehicles on several
fronts.  Last month, State agency leaders responding to an
executive order from the Governor issued the Sustainable Freight
Action Plan, a blueprint for modernizing the state’s
multi-billion dollar freight transport system including ships,
trucks and rail with a focus on zero- and near-zero emission
technologies.  

First adopted in 2008, the Statewide Truck and Bus regulation is
a cornerstone of CARB’s overall plan to significantly reduce
diesel emissions from a variety of sourcesas called for in the
Diesel Risk Reduction Plan, adopted in 2000.

In May, CARB issued a comprehensive Mobile Source Strategy.  Its
goals for heavy duty vehicles include:
•	Lowering emissions; 
•	Establishing more stringent NOx standards for new engines; and
•	Accelerating deployment of zero and near-zero emissions
technology.
