The Government have made a commitment to work towards full compliance with EU air quality standards. Air quality has improved significantly in recent decades; the UK now meets most EU air quality standards thanks to action taken by the Government over many years to reduce emissions, including from industrial, energy and transport sources. However, there are still more improvements to be made and we will continue to investigate new measures to improve air quality, working with external stakeholders in transport and other sectors. We work closely with local authorities and the Greater London Authority, which have responsibility for local air quality. We also support actions to reduce pollution through tackling congestion, promoting cycling and walking, and improving vehicle fleets.
