As outlined in the 2020 Mobile Source Strategy and the 2022 State Strategy for the State Implementation Plan, CARB is exploring strategies to reduce emissions associated with aircraft operations while on or near the ground at airports.  Currently, these strategies include reduced or zero-emission taxiing, transitioning ground support equipment (GSE) to zero-emission, strategics to minimize use of auxiliary power units (APU), and reduce emissions from landing and takeoff.  The Statewide Clean Aviation Initiative (SCAI) would provide necessary emissions reductions to attain federal air quality standards, lower health risk to airport workers and nearby communities, and reduce greenhouse gas emissions from airport operations.
