In 2022, the California Air Resources Board (CARB) committed to developing strategies to reduce emissions from aviation. That process is now well underway.

In March of last year, I attended and reported on a CARB forum focused on technology solutions that could curb climate pollution from the aviation sector. Since that meeting, staff have prepared draft concepts for potential programs and policies that could be brought to the agency’s board for action next year.

Earlier this month, the agency hosted a public workshop to share more details about the four concepts under consideration, which focus on airport operations on the ground and at the gate: controlling emissions from aircraft auxiliary power units; reducing emissions from airport ground support equipment; reducing emissions from aircraft taxiing at the airport; and reducing emissions from aircraft takeoffs and landings.
