Study: ULEZ Expansion Fails to Reduce London Air Pollution Significantly

A recent study indicates the expansion of Londons Ultra Low Emission Zone has not significantly reduced air pollution, casting doubt on the initiatives effectiveness and financial investment.

• The Ultra Low Emission Zone was expanded in August 2023, costing approximately £155 million, yet failed to significantly lower air pollution levels in London.
• Research from the University of Birmingham reveals that nitrogen dioxide and nitric oxide levels in Central London remain above international health-based guidelines post-expansion.
• Despite the introduction of the Ultra Low Emission Zone, Greater London continues to struggle with high levels of pollution, with NOx emissions not showing a significant decline.
