New data shows London’s expanded low-emissions zone significantly reduced harmful emissions, proving effective in improving air quality. In short:London’s Ultra Low Emission Zone (ULEZ) expansion cut particulate matter by 22% and nitrogen oxide by 21% in outer London. Mayor Sadiq Khan faced political backlash but won re-election, showing public support for the policy. The ULEZ is expected to reduce fee collections as more vehicles comply with emissions standards. Successful implementation in London may encourage other cities to adopt similar measures, aiding global efforts to combat climate change.
