California Air Quality and Climate Legislation

CARB’s Office of Legislative Affairs serves as the principal resource on legislative issues relative to air quality and climate change for the California Environmental Protection Agency and the Governor’s Office. The Office of Legislative Affairs provides technical expertise relating to pending legislation and serves as a resource to the Legislature and legislative staff.

CARB's 2020 California Air Quality and Climate Legislation webpage catalogues the most pertinent legislation that CARB's Office of Legislative Affairs tracked during the previous Legislative session. Beginning with the 2020 session, CARB transitioned to this modernized, web-based platform, which can be accessed below. The annual summaries for the 1998 through 2019 sessions are available at CARB's California Air Quality Legislation Archive.
