The protection of air quality is a priority for the European Commission. Emission standards are currently in place for light–duty (cars, vans) and heavy-duty vehicles (coaches, buses, trucks), and for non-road mobile machinery. The Commission also encourages technological development to help protect the environment and reduce air pollution.
In September 2017, the Commission introduced an improved mandatory car emissions test to reduce vehicle emissions. In March 2018 the Commission held a public consultation on its new proposal to improve the tests. The Technical Committee on Motor Vehicles (TCMV) voted on the proposal on 3 May. More on the proposal
