8/20/2026

Summary

London ULEZ Improves

London’s Ultra Low Emission Zone (ULEZ) accelerated lung growth in primary-school children.
Nitrogen-dioxide levels declined 3.8 µg/m³ per year in London, twice the 1.8 µg/m³ drop in Luton.
Impaired lung function fell from 14% to 9% in London and from 9% to 7% in Luton after four years.
London’s FEV1 increased about 10 mL per year more than Luton’s, closing the gap.

Summary

Perry urges vandalism

Mayor Jason Perry and MP Chris Philp led a group urging vandalism of ULEZ cameras, costing hundreds of thousands.
Perry will host a Motorists’ Forum to propose scrapping 20 mph zones and reviewing Croydon School Streets.
ULEZ charges drivers £12.50 per day and operates continuously around the clock.
A £200 million scrappage scheme removed 15,232 old, non-compliant vehicles from London roads.
Most Londoners backed ULEZ, helping Mayor Sadiq Khan win re-election despite opposition.
