PARLIAMENTARY WRITTEN QUESTION
Air Pollution: Greater London (19 July 2021)

The Mayor of London is responsible for air quality in the capital and has reserve powers under Part IV of the Environment Act 1995 to reflect this.

As part of these responsibilities the Mayor of London carries out monitoring of air quality in London. Local authorities are required to review and assess local air quality and in London they report their data to the Mayor.

The London Air Quality Network provides data on air quality in London accessible to the public.

Air pollution has reduced significantly since 2010 – emissions of nitrogen oxides are at their lowest level since records began. We are continuing to deliver our ambitious plans to improve air quality. To tackle local nitrogen dioxide exceedances, we are providing £880 million to help local authorities develop and implement local air quality plans and to support those impacted by these plans. Our Clean Air Strategy set out an ambitious programme of action to reduce air pollution from a wide range of sources. Our Environment Bill delivers key parts of this Strategy and makes a clear commitment to set a legally binding target to reduce fine particulate matter and enables local authorities to take more effective action to tackle air pollution in their areas.
