The California Air Resources Board applauds announcement of final
Tier 3 regulations 

U.S. EPA action sets stage for cleaner cars and light trucks
nationwide 2017-2025

SACRAMENTO - Today, California Air Resources Board Chairman Mary
Nichols congratulated U.S. EPA Administrator Gina McCarthy on the
release of the final Tier 3 regulations to significantly reduce
smog- and soot-forming emissions from 2017-2025 model-year cars
and light trucks. 

“California congratulates EPA on this latest step in aligning
federal low-emission vehicle and fuel standards with California's
stricter standards,” said California Air Resources Board Chairman
Mary Nichols.  “This move sets the stage for a single set of
requirements that will facilitate development of cleaner cars and
light trucks and bring the benefits of healthier air to
communities across the country.”

The Tier 3 vehicle regulations are modeled on California’s
Low-Emission Vehicle III (LEV III) regulations that were adopted
in early 2012 as part of California’s Advanced Clean Cars
Program.  The Advanced Clean Cars Program was designed to clean
the air, fight climate change, deliver savings to consumers, spur
automotive technology innovation, and drive job development in
California.  The LEV III program combines the control of smog-
and soot-forming pollutants and greenhouse gas emissions into a
single coordinated package of requirements for model years 2015
and beyond.

The Tier 3 rule lowers the sulfur limits in gasoline to a 10
parts per million (ppm) annual average, a standard that will
deliver immediate and significant reductions in emissions from
current vehicles.  This will also better align national gasoline
specifications with California’s requirements, benefiting public
health, consumers, and the car industry. 

California's clean fuel requirements, in place since the 1990s,
have delivered emission reductions equivalent to removing 3.5
million vehicles from the state's road and highways. 
California's fuel rules alone have reduced smog-forming emissions
from motor vehicles by 15 percent, reduced potential cancer risk
from vehicle emissions by 40 percent, and slashed toxic emissions
(including benzene) in half.

While many elements of the Tier 3 vehicle regulations mirror
California’s LEV III regulations, a number of critical
differences remain that are vital for meeting California’s air
quality goals.  Most notably, the LEV III regulations reduce soot
in emissions in 2025 to a greater extent than the levels required
under the Tier 3 standard. Also, under the Advanced Clean Car
Program, California continues its zero-emission vehicle mandate
to accelerate the development of ultra-clean technologies by
requiring manufacturers to produce increasing numbers of
zero-emission vehicles and plug-in hybrid electric vehicles in
the 2018-2025 model years.  

California remains committed to continue to lead on innovative
and ground-breaking air quality programs that benefit the State
and serve as a model for the nation.  California looks forward to
collaborating with the federal agencies to achieve the lowest
feasible levels of greenhouse gas, smog, soot, and toxic air
emissions, both in California and throughout the country. 

California is in a drought emergency.
