Air Quality Program

Get involved

Read the Volkswagen blog

Read our blog about the investigation by the EPA that revealed Volkwagen manufactured diesel vehicles with software that cheated emission tests by only turning on the vehicle’s emission control systems when the car was being tested. As a result, VW agreed to multiple settlements, one being a Mitigation Trust Fund. Washington is eligible to receive $112.7 million from this fund.

Weigh in on the goal, principles, and priorities

We have launched a survey that gives people, governments, and groups an opportunity to weigh in. The survey closes at 5 p.m. March 23, 2017.

There are very specific requirements that states have to include in their plans. One of the requirements is giving the public an opportunity to provide feedback on the approach states are taking for project selection. So, we want to hear what you think about the goal, overarching principles, and project priorities that we will include in Washington’s plan when we draft it.

Please watch the introductory video below then take the 3-minute survey.

  • Fully mitigate total lifetime excess of nitrogen oxide emissions from affected VW vehicles.


  1. Maximize air quality benefits and improve public health.
  2. Ensure cost effectiveness.
  3. Benefit sensitive populations and highly-impacted communities.

Project priorities:

  1. Air quality co-benefits (reducing other pollutants) beyond nitrogen oxide reductions.
  2. Leverage additional funds.
  3. Promote transformational change in vehicle emissions reductions.
  4. Accelerate adoption of electric vehicles.
  5. Use proven technologies.
  6. Accelerate fleet turnover to cleaner engines.
  7. Substantial additional emission reductions.
