Washington Gov. Jay Inslee has signed an executive order that outlines a plan for an all-electric state fleet by 2040.

The order, which Inslee signed Nov. 3, details specific target goals for roughly 5,000 of the state’s vehicles.

For passenger vehicles and trucks Class 1-2a, it requires at least 40% of the fleet to be electric by 2025, 75% by 2030, and 100% by 2035. 

For medium- and heavy-duty vehicles and trucks, the order requires 30% of those to be electric by 2030 and 100% by 2040. If an electric model is not available for certain applications, state agencies will be required to seek out the “lowest emission, cost-effective option including, but not limited to, plug-in hybrid electric vehicles and hydrogen fuel cell technologies,” according to the order.

Implementation of EV plans are expected to be carried out by the State Efficiency and Environmental Performance (SEEP) office and the state Department of Enterprise Services (DES). Together, they will handle fleet transition schedules, vehicle purchase exemption criteria, and an exemption review and approval process, by which agencies may seek exemption for specific state fleet vehicles.
