The civil Clean Air Act matter was resolved through court-approved partial consent decrees. EPA records a USD 1.45 billion civil penalty under the third partial settlement (approved 13 April 2017), a USD 2.7 billion mitigation trust and a USD 2 billion zero-emission-vehicle investment under the 2.0-litre settlement, plus recall, buyback, lease-termination and future-compliance obligations. This civil resolution is distinct from Volkswagen's separate criminal plea with the Department of Justice.
