Advanced Clean Car Program

The LEV regulation, adopted in 1990, set a new standard for vehicle emissions. Over the years, the regulation has been amended several times to continue to push the automakers that sell cars in California to meet goals for tailpipe emissions, evaporative emissionsEmissions produced from fuel evaporation and greenhouse gasA gas in Earth's atmosphere that traps heat and can contribute to global warming. Carbon dioxide and methane are two GHGs. emissions.

At the end of January, the California Air Resources Board adopted amendments to the set of regulations and unified them under the Advanced Clean Cars Program. The amendments effect new cars sold between 2017 and 2025 and includes the following elements:

  • Enact new emission standards beginning with 2015 model year vehicles so that by 2025 cars will emit 75% less smog-forming pollution than the average new car sold today.
  • Reduce greenhouse gas emissions from new cars by 34% in 2025.
  • Include new types of vehicles in the ZEV category, require “intermediate” automakers to place ZEVs on the road and refine the credit system for early compliance.
  • Amend the Clean Fuels Outlet regulation to ensure hydrogen and electricity are available as vehicles come to market.

California has a long and successful history of adopting technology-advancing vehicle emission standards to protect public health. The pioneering measures have accelerated the introduction of cleaner cars for a healthier California.
