Investing in cleaner transportation

We invest funds from the Volkswagen settlement and our Clean Diesel program in projects that reduce emissions from transportation. These investments help improve air quality and people's health. They support the transition to zero-emission transportation systems in Washington. We prioritize projects that benefit communities disproportionately impacted by air pollution.

Improving air quality for people's health and the environment

Diesel-powered vehicles, vessels, and equipment emit nitrogen oxides, fine particles, greenhouse gases, and other air pollutants that hurt people's health and the environment. People who live near busy roads, ports, railways, and other transportation corridors may be at higher risk of negative health effects, such as persistent coughing, asthma, lung diseases, and other health issues.

Environmental justice and equity

The Healthy Environment for All (HEAL) Act requires us and our partners to identify and address environmental health disparities in overburdened communities and underserved populations. Our Office of Equity and Environmental Justice leads our strategy to reduce pollution and health disparities in communities most at risk.

We use the Washington Department of Health’s Washington Tracking Network (WTN) map to help us identify disproportionately-impacted areas and prioritize where to invest funds.

Clean transportation policy and coordination

Our clean transportation grants support projects that reduce pollution from diesel vehicles by replacing them with zero-emission vehicles. We prioritize project investment in areas disproportionately-impacted by air pollution, and incentivize the purchase and installation of necessary fueling infrastructure.

Statewide efforts — such as the Climate Commitment Act, the Clean Fuel Standard, and zero-emission vehicle standards — also support and incentivize the transition to zero-emission transportation in Washington.

The Washington Interagency Electric Vehicle Coordinating Council (EV Council) was created in the 2022 legislative session, so state agencies can better collaborate on efforts to accelerate electric vehicle adoption and reduce transportation sector greenhouse gas emissions.
