Overview of the Proposed Federal
Passenger Vehicle Rollbacks

Advanced Clean Cars Background

  • In 2012, CARB adopted Advanced Clean Cars:
    – Standards for light-duty criteria pollutants, GHG emissions, and zero emission vehicles (ZEV) through model year 2025
  • EPA and NHTSA adopted similar regulations for greenhouse gases and fuel economy to create One National Program.
    – CARB allows automakers to comply with EPA’s GHG standards in lieu of California’s

Federal Agencies’ Proposed Rollback

  • Fuel economy and greenhouse gas emission standards for new vehicles would not improve beyond model year 2020
  • CARB (and other states) cannot regulate GHG tailpipe emissions
  • CARB (and other states) cannot enforce its existing ZEV regulation (nor adopt future, more stringent ZEV requirements)

Emission Impacts to California

  • Federal proposal increases GHG, criteria, and local toxic emissions due to increased vehicle emissions and refinery activity
  • 12 million metric tons additional GHG emissions in 2030 in California; ~60 MMT cumulative by 2030
  • 1.24 tons per day increase in NOx emissions in the South Coast in 2030
  • Slowed progress towards decarbonization

Additional Impacts to California

  • Delay of ZEV deployment in light-duty vehicles will also delay ZEV technology transfer to heavy-duty vehicles that is necessary for long-term attainment in South Coast and other parts of California
  • Rollback will hamper California’s ability to mitigate climate change
    – Air pollution impacts exacerbated as climate change worsens

What’s next?

  • Trump administration proposal would severely impact California as well as the nation
  • Excess emissions and slowed technology adoption would move California to look at a range of control and planning options to address
  • Litigation certain and complex
