In April 2018, the US Environmental Protection Agency (EPA) completed the Midterm Evaluation (MTE) process for the greenhouse gas (GHG) emissions standards for cars and light trucks for model years 2022-2025, and determined that the current standards are not appropriate and should be revised. (Earlier post.)
The California Air Resources Board (CARB) GHG standards allow manufacturers the option to comply by meeting the US EPA greenhouse gas standards through model year 2025 as currently defined (referred to as the “deemed to comply” provision). CARB disagrees with the April EPA decision, and may consider amending its regulations to clarify that the deemed to comply provision applies to the current federal GHG standards, should US EPA change the standards for any model years.
Under this approach, CARB would not change any of the regulatory requirements in the LEV III GHG regulation. CARB would, however, take regulatory action as needed to clarify that the compliance with any weakened federal standards will not be deemed compliant with CARB standards for the specified model years.
CARB is soliciting public input on potential alternatives to this amendment. . . .
