California Air Resources Board

On February 21, 2019, the Board adopted the Zero-Emission Airport Shuttle (ZEAS) regulation to improve public health and fight climate change. The regulation is part of the 2016 State Implementation Plan, California’s roadmap toward achieving federal health-based standards, and expands the use of zero-emission technologies in the heavy-duty sector to achieve NOx and GHG emission reductions. The regulation will accelerate the adoption of zero-emission technology in airport shuttles that are well suited for electrification. As part of a comprehensive suite of measures tasked to meet our air quality and climate goals, the regulation will virtually eliminate tailpipe emissions from airport shuttles operating at and around California airports, thus improving the air quality in impacted communities both regionally and throughout the State.
