LOS ANGELES—California air quality officials Jan. 27 adopted new standards requiring automobile manufacturers, over the next 13 years, to reduce ozone-forming emissions from cars and light-duty trucks by 75 percent from 2014 levels and put 1.4 million plug-in hybrids, battery electric, and fuel cell vehicles on the road.
Approved 9-0 by the California Air Resources Board, the regulatory package includes a rule to phase in stricter fleet average standards for 2015-2025 model year cars and light-duty trucks to further reduce nitrogen oxide and hydrocarbon emissions, increase engine durability requirements from 120,000 miles to 150,000 miles, and impose new particulate emissions on gasoline cars.
A second rule puts in place a new round of greenhouse gas emissions standards for 2017-2025 model year cars and light-duty trucks. CARB's new regulations set a 166 gram of carbon dioxide equivalent per mile limit, which the agency said will curb greenhouse gases 4.6 percent a year, or 34 percent from 2016 to 2025.
The new regulations ushered in what appears to be a new era of cooperation between automakers and the agency, one rooted in the negotiations that led to the agreement on nationwide greenhouse gas standards for cars and stricter fuel economy standards finalized by the Obama administration in 2010 (62 DEN A-7, 4/2/10).
The regulatory package, collectively called the Advanced Clean Cars Program, still must be approved by the California Office of Administrative Law and the Environmental Protection Agency.
Automakers testifying at the public hearing that preceded the board's vote voiced strong support for the rules even though they called on CARB to tweak various provisions in the regulations.
Generally, the industry urged CARB to continue ongoing efforts to harmonize the state's testing and certification requirements with those of the Environmental Protection Agency.
CARB Deputy Executive Officer Tom Cackette told Bloomberg BNA the two agencies are close in achieving that goal.
“The level of consensus on the importance of the program was the highest we've ever seen,” CARB Chairman Mary D. Nichols said in a news conference following the vote.
Environmental and public health advocates also voiced strong support for the rule package and encouraged CARB to closely monitor automakers' compliance.
The Advanced Clean Car Program “represents a new chapter for clean cars in California and the nation as a whole,” Nichols said “It's going to be an exciting time in the next few years as we see manufacturers roll out these new cars.”
A coalition of environmental, consumer groups, citizens, and public health groups called the California Clean Cars Campaign praised passage of the rules.
“The new standards will save consumers money, cut dangerous air pollution, and support the creation of new jobs and investment in the fast-growing clean energy economy,” the group said in written statement.
In his testimony, Jack Gilles of the Consumer Federation of America cited surveys from Consumer Reports showing broad support for California regulations that reduce greenhouse gases and increase fuel economy.
“Consumers understand the benefits and have consistently voiced support of California's leadership on clean car standards,” Gilles said. “In fact, CFA's latest poll found that more than 70 percent of Americans support states being allowed to continue setting tailpipe emission standards that, as a result, increase fuel economy for motor vehicles.”
CARB will amend the greenhouse gas emissions rule to allow automakers compliant with federal standards being promulgated by the Obama administration to meet the state's requirements.
California's greenhouse gas rules rely on off-the-shelf technologies, including variable valve controls, direct injection, turbochargers, cylinder deactivation, engine stop-start, low-emitting refrigerants for air conditioning systems, and improvements in transmissions.
Nichols said the final federal standards must be consistent with those proposed by EPA and the National Highway Traffic Safety Administration, which would translate to an average fleet standard of 54.5 miles per gallon by 2025 (76 Fed. Reg. 74,854; 222 DEN A-7, 11/17/11).
CARB also approved amendments to landmark 1990 zero-emission vehicle rule to ensure that at least 15.4 percent of the cars on the state's road in 2025 are a mix of advanced technologies.
The changes become more stringent for 2018 model year vehicles and beyond to push for “pure” zero-emission vehicles such as plug-in hybrids, battery electric, and fuel cell vehicles. Specifically, the amendments end the opportunity for automakers to earn ZEV credits for near-zero emission cars such as any of the current generation of gas-electric hybrids and those with clean gasoline engines.
CARB also agreed to continue a “travel” provision allowing automakers to pool sales of zero-emission in other states with similar rules to meet California's requirement. States so far with zero-emission rules are Connecticut, Maine, Maryland, Massachusetts, New Jersey, New Mexico, New York, Oregon, Rhode Island, and Vermont.
Several automobile manufacturers and environmental groups sought to convince CARB to abandon a provision in the amendments allowing automakers who over-comply with the national greenhouse gas standard to satisfy ZEV requirements between 2018 and 2021. Automakers that make the highest volume of fuel-efficient cars would be able to earn credits to satisfy the ZEV requirements.
Industry representatives called the provision unfair, and environmental and public interest groups expressed concern that it would result in the introduction of fewer zero-emission vehicles.
CARB's Cackette told Bloomberg BNA that American Honda Motor Co. Inc. and Hyundai were the two most likely automakers to benefit from the over-compliance provision because both companies produce a large volume of fuel efficient vehicles.
Steve Douglas of the Alliance of Automobile Manufacturers argued that all the companies should be held to standard for investing in zero-emission vehicles.
Individual CARB members were swayed by the concerns raised, but Nichols explained that the provision grew out of the negotiations for the nationwide program and she was unwilling to jeopardize that agreement.
In the end, the board agreed to provide some procedural requirements to the provision requiring automakers that opt for the over-compliance route to submit additional data to ensure the agency's goals for 2025 would be met.
A measure designed to ensure a hydrogen fueling infrastructure for the growing number of fuel-cell vehicles the state hopes will be introduced drew fire from the oil industry and a threatened lawsuit.
Called the Clean Fuels Outlet rule, the measure would require oil companies to invest in building hydrogen fuel facilities and offer existing gasoline stations incentives to welcome the new type of fuel service.
The Western States Petroleum Association (WSPA) and many small business groups testifying at the hearing challenged CARB's authority for such a mandate. The industry is working with CARB to negotiate an agreement to pursue public funds for loan guarantees to make such investments.
WSPA President Cathy Reheis-Boyd told Bloomberg BNA that a lawsuit “was highly likely.” Reheis-Boyd said the rule is unconstitutional and violates the Commerce Clause of the U.S. Constitution.
Nichols said she hopes the industry will continue to negotiate with the agency. The clean fuel facilities are necessary for mass production of fuel-cell vehicles, she said.
“The future lies in these advanced vehicles,” Nichols said.
