Covid-19 restrictions have pushed concern about air quality down the political agenda. Many councils that had been planning to introduce measures to reduce air pollution levels in their cities have postponed or cancelled them.

Despite this, after an initial drop in air pollution this year it has since been rising again. As a result, NO2 levels have now hit or exceeded pre-pandemic levels in around 80% of places studied according to new research by Centre for Cities and the Centre for Research on Energy and Clean Air.

To discuss this issue in more detail, Andrew Carter is joined by the authors of the new research Centre for Cities’ Valentine Quinio and the Centre for Research on Energy and Clean Air’s Hubert Thieriot.
