Note: The following email was distributed Aug. 15 by Caltrans Chief Deputy Director Michael D. Keever.

Jimmy O’Dea is the new assistant deputy director for transportation electrification and works out of the Director’s Office of Sustainability.

As part of its commitment to climate action, Caltrans will continue its unrelenting efforts to reduce greenhouse gas emissions from the transportation sector. Electrifying our transportation network and accelerating the deployment of zero-emission vehicles (ZEVs) and charging infrastructure – and also championing the transition to zero-emission transit, rail, and freight systems – will be key in the fight against the climate crisis.

Jimmy comes to Caltrans with 18 years of experience in zero-emission vehicles and policy. He was previously deputy director of trucks at CALSTART, where he worked with businesses to advance federal and state policies supporting the widespread electrification of medium- and heavy-duty vehicles, including the “Commercial Clean Vehicle” tax credit in the Inflation Reduction Act.  

Prior to joining CALSTART, Jimmy was senior vehicles analyst at the Union of Concerned Scientists, where he played key roles in the strengthening and adoption of first-of-their-kind policies for electric trucks and buses, including the Advanced Clean Trucks and Innovative Clean Transit standards in California.   Jimmy was a Science and Engineering Congressional Fellow in the office of U.S. Senator Brian Schatz (D-Hawaii). In postdoctoral and graduate research in chemistry at Cornell and UC Santa Barbara, he studied materials used in fuel cells, batteries and solar cells.

Over the next few months, Jimmy and the Director’s Office of Sustainability will be working with many of you to re-orient and set a new direction for this next chapter of our journey toward a zero-emissions transportation system. Please join me in welcoming Jimmy to the Caltrans family!
