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.
