Exclusive: mayor hails ‘remarkable progress’ in improving capital’s air quality, saying good proportion of change is result of Ulez expansion
Sadiq Khan has hailed what he said was remarkable progress in improving London’s air quality under his tenure as mayor, after a study showed roadside pollutant levels falling faster in the city than elsewhere in the UK.
The report, produced by the Greater London Authority (GLA) and Transport for London (TfL), said a good proportion of the improvement was the result of the ultra-low emission zone (Ulez), which was extended to all London boroughs last summer.
