Green transportation describes many types of mobility that conserve energy, increase efficiency, and use clean and renewable alternative fuels. The transition from fossil fuels—gasoline and diesel—is well underway. Washington consumers and fleets increasingly use alternative fuels, such as clean electricity, biofuels, and renewable fuels, to move people and goods.

This is especially true for public fleets. The Washington legislature set ambitious goals and provides grants and incentives to support green transportation at all levels of government. The WSU Energy Program maintains this Green Transportation website to provide education and technical assistance to support public fleets’ transition to cleaner fuels.

Policy Updates

Washington Adopts Plan for Transition to Zero-Emission Vehicles

On Dec. 19, 2022, the Washington Department of Ecology updated its Clean Vehicles Program to require that all new, light-duty vehicles sold in Washington meet zero-emission vehicle (ZEV) standards by 2035. The press release goes on to say, “Ecology has adopted the new standards after a six-week public comment period. The department received and responded to more than 1,400 comments. . . The transition to ZEVs will work alongside Washington’s other major new climate policies – the Clean Fuel Standard and Cap-and-Invest Program – both of which begin on Jan. 1, 2023.

Rulemaking Underway by WA Departments of Agriculture and Ecology

The Washington State Department of Agriculture (WSDA) is required to conduct rule making related to electric vehicle supply equipment (EVSE). An overview of the rulemaking process, estimated timeline, and plans for stakeholder involvement is provided on the WSDA website. The current draft of the proposed rule is available for review here.

The Washington State Department of Ecology is starting rulemaking for the Clean Fuels Program Rule, which will:

  • Establish carbon intensity standards for transportation fuels used in Washington.
  • Assign compliance obligations to fuels with carbon intensities that exceed the standard.
  • Establish compliance methods including assigning credits to fuels that have carbon intensities below the standard.

More information is provided on the Ecology website.
