Biodiesel Use Requirement

At least 20% of all diesel fuel used to fuel state agency vehicles, vessels, and construction equipment must be biodiesel. The Washington Department of Enterprise Services (WDES) must assist state agencies by coordinating the purchase and delivery of biodiesel if requested, using long-term contracts if necessary, to secure a sufficient and stable supply of biodiesel. For state agencies complying with the U.S. Environmental Protection Agency's ultra-low sulfur diesel (ULSD) mandate, at least 2% biodiesel (B2) must be used as an additive to ULSD for lubricity, provided that the use of a lubricity additive is appropriate and that performance and cost are comparable with other available lubricity additives. All agencies using biodiesel must submit annual consumption reports to WDES. (Reference Revised Code of Washington 43.19.642 and 43.19.646)

State Plug-In Electric Vehicle (PEV) Charging Infrastructure Availability

Publicly and privately owned PEVs may charge at state office locations if the vehicles are used for state business, conducting business with the state, or as commuter vehicles. Additionally, contingent upon funding, the state must install electrical outlets suitable for charging PEVs in each of the state's fleet parking and maintenance facilities as well as every state-operated highway rest stop. The Washington Department of Enterprise Services may report to the governor and the legislature on the amount of electricity consumed and the number of PEVs using state-owned charging equipment if it represents a significant cost to the state. (Reference Revised Code of Washington 43.01.250, 43.19.648, and 47.38.075)

Alternative Fuel Use Requirement

All state agencies must, to the extent practicable, use 100% biofuels or electricity to operate all publicly owned vehicles. Agencies must prioritize all-electric vehicles (EVs) when leasing or purchasing new vehicles, and all trips that may feasibly use EVs must employ them. For vehicle classes without EV model options, agencies must prioritize the most cost-efficient, low-emission vehicle option available. Agencies may substitute natural gas or propane for electricity or biofuel if the Washington State Department of Commerce (Department) determines that electricity and biofuel are not reasonably available. Practicability and measures of compliance are defined in rules adopted by the Department. The governor has established a cross-agency Governing Council, which must adopt and implement standards, measures, targets, and tools to support agencies in reducing greenhouse gas emissions and prioritizing EV adoption.

In addition, all local government agencies must, to the extent practicable, use 100% biofuels or electricity to operate all publicly owned vehicles. Transit agencies using compressed natural gas and engine retrofits that would void vehicle warranties are exempt from this requirement. To allow the motor vehicle fuel needs of state and local government to be satisfied by Washington-produced biofuels, the Washington Department of Enterprise Services and local governments may contract in advance and execute contracts with public or private producers and suppliers for the purchase of appropriate biofuels. Agencies may substitute natural gas or propane in vehicles if the Department determines that biofuels and electricity are not reasonably available. Practicability and measures of compliance are defined in rules adopted by the Department.

Plug-In Electric Vehicle (PEV) Promotion and Infrastructure Development

Any regional transportation planning organization containing a county with a population greater than one million must collaborate with state and local governments to promote PEV use, invest in PEV charging infrastructure, and seek federal or private funding for these efforts. Collaborative planning efforts may include:

• Developing short- and long-term plans outlining how state, regional, and local governments may construct electric vehicle supply equipment locations and ensure that the infrastructure can be electrically supported;
• Supporting public education and training programs on PEVs;
• Developing an implementation plan for counties with a population greater than 500,000 to have 10% of public and private parking spaces ready for PEV charging by December 31, 2018; and
• Developing model ordinances and guidance for local governments for site assessment and installing PEV infrastructure.

Low Carbon Fuel and Fuel-Efficient Vehicle Acquisition Requirement

Washington state agencies must consider purchasing low carbon fuel vehicles or converting conventional vehicles to use low carbon fuels when financially comparable over the vehicle's useful life. Low carbon fuels include hydrogen, biomethane, electricity, or natural gas blends of at least 90%. State agencies must achieve an average fuel economy of 36 miles per gallon (mpg) for passenger vehicle fleets in motor pools and leased conventional vehicles. State agencies must also purchase low carbon fuel vehicles or, when purchasing new conventional vehicles, achieve an average fuel economy of 40 mpg for light-duty passenger vehicles and 27 mpg for light-duty vans and sport utility vehicles. When calculating average fuel economy, emergency response vehicles, passenger vans with a gross vehicle weight rating of 8,500 pounds or greater, off-road vehicles, low carbon fuel vehicles, and vehicles driven less than 2,000 miles per year are excluded. (Reference Revised Code of Washington 43.19.622)

Alternative Fuel Vehicle (AFV) Car Share Pilot Program

The Washington State Department of Transportation (WSDOT) will develop a pilot program to provide AFV use opportunities to underserved and low-income communities and to those without easy access to transportation corridors. (Reference Revised Code of Washington 47.04.355)

Low Carbon Fuel Standard

The Washington Department of Ecology will develop rules to establish a Clean Fuels Program (Program) that reduces the overall carbon intensity of transportation fuels used in the state by 20% below 2017 levels by 2035. The Program standards must be based on the carbon intensity of gasoline, gasoline substitutes, diesel, and diesel substitutes. The Program must go into effect no later than January 1, 2023.
