California Air Resources Board Approves Advanced Clean Car Rules

New rules will save drivers money on fuel, create jobs, cut smog and greenhouse gases, make California a world leader in clean car technology

LOS ANGELES - Today the California Air Resources Board unanimously approved a package of new emissions rules for cars and light trucks through 2025.

“The California Advanced Clean Car rules will clean our air, fight climate change and provide cars that save consumers thousands of dollars at the pump,” said ARB Chairman Mary D. Nichols. “The Board’s action today will create thousands of new jobs, transforming California into the advanced car capital of the world. California is now in pole position in the race to provide next-generation ultra-clean cars to the global car market.”  
The Advanced Clean Cars program combines the control of smog-causing pollutants and greenhouse gas emissions into a single coordinated package of requirements for model years 2017 through 2025. The new rules will clean up gasoline and diesel-powered cars, and deliver increasing numbers of zero-emission technologies, such as full battery electric cars, newly emerging plug-in hybrid electric vehicles and hydrogen fuel cell cars. The package will also ensure adequate fueling infrastructure is available for the increasing numbers of hydrogen fuel cell vehicles planned for deployment in California.

The Advanced Clean Cars program has been in development over the past three years and is composed of four separate, but related components.  An overview of the program is included further below.

The rules are designed to preserve consumer choice while ensuring the development of a full range of environmentally superior cars from compacts to SUVs and pickups. These vehicles will continue to deliver the performance, utility and safety vehicle owners have come to expect with significant savings thanks to reduced operating costs.

Many of the technologies that reduce climate change emissions also significantly reduce the operating costs of passenger vehicles on a month-to-month basis for consumers.

The Advanced Clean Cars program has been in development over the past three years and is composed of four separate, but related components:
  1. Greenhouse gas standard for cars and light trucks, model years 2017-2025

    The greenhouse gas standard approved today builds on California’s first-in-the-nation standard that was later adopted in 2010 by the federal government as part of a national program. The new rules strengthen the greenhouse gas standard for 2017 models and beyond. They were developed in tandem with the federal government over the past three years, including an unprecedented joint fact-finding process with shared engineering and technical studies.

    The current California program constitutes a separate set of rules with minor variations due to separate legal structures but is designed to parallel the proposed federal joint rulemaking the Obama administration announced last summer. Once the proposed federal standards are adopted, they will be deemed sufficient for compliance in California. This responds to the desire for a streamlined set of rules for new cars and light trucks and creates a single national program for manufacturers that addresses both greenhouse gas and fuel economy standards.

    The new standard drops greenhouse gas emissions to 166 grams per mile, a reduction of 34 percent compared to 2016 levels. This will be achieved through existing technologies, the use of stronger and lighter materials, and more efficient drivetrains and engines.

  2. Reducing Smog-Forming Emissions

    California will need to reduce smog-forming pollution by an additional 75 percent from 2014 levels to help meet more stringent federal air quality standards expected in the next few years. Since California continues to have the nation’s worst air quality, and has more than 26 million cars on the road, it is necessary to further reduce smog-forming pollution from cars. This regulation will drive the development of the cleanest cars yet that use diesel, gasoline, or gas-electric hybrid internal combustion engines. (Note: The above two regulations are bundled into a single document under the title “LEV III“.)

  3.  Zero Emissions Vehicle (ZEV) Regulation

    The ZEV regulation will result in over 1.4 million ZEVs on the road by 2025 (15.4 percent of new vehicle sales in that year) in order to be on track to reach the 2050 greenhouse gas reduction goal. A transitional model – the plug-in hybrid car – will play a significant role over the next 20 years, but by mid-century, 87 percent of cars on the road will need to be full zero-emission vehicles to achieve climate goals.

    The ZEV regulation builds on the program in place since 1990 and is designed to rapidly increase ZEV production to early commercial volumes, establishing a sustainable and growing market for these advanced technology vehicles. This will place California on a path to reduce greenhouse gas emissions by 80 percent by 2050, a goal adopted by many nations and believed necessary to stabilize climate temperature.

  4.  Clean Fuels Outlet

    This regulation is designed to support the commercialization of zero-emission hydrogen fuel cell vehicles planned by vehicle manufacturers by 2015, which will require increased numbers of hydrogen fueling stations. Construction of the new stations will provide a convenient fueling infrastructure, first within the major metropolitan areas, but ultimately throughout the state. The number of stations will grow as vehicle manufacturers sell more fuel cell vehicles.
