New data shows London’s expanded low-emissions zone significantly reduced harmful emissions, proving effective in improving air quality.
Somini Sengupta reports for The New York Times.
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.
Key quote:
“The decision to expand the ULEZ was a difficult one, but the right one.”
— Sadiq Khan, Mayor of London
Why this matters:
Reducing emissions in urban areas can improve public health by decreasing respiratory issues like asthma. Successful implementation in London may encourage other cities to adopt similar measures, aiding global efforts to combat climate change.
