The $219 million revenue riddle

The Ultra Low Emission Zone (ULEZ) generated a record £219 million in revenue in 2024, up from £215 million the previous year, according to the charity Asthma + Lung UK, which collaborated on the analysis.

While acknowledging the zone's role in reducing pollution, the charity stressed that people with lung conditions need accurate data to protect themselves.

The findings come as Mayor Sadiq Khan's claims that London met legal limits for nitrogen dioxide (NO2) for the first time in 2024 are being challenged by local data.

Despite the Mayor's assertion,local authority monitoring stations reveal that more than half of the city's boroughs are still recording illeggal levels of the toxic gas.

Experts question the reliance on a sparsse national monitoring network,urging for more localized data to protect public health.

A new analysis of air quality data from London boroughs has cast doubt on the effectiveness of the Ultra Low Emission Zone (ULEZ) in improving air quality across the capital.

The ULEZ, which charges drivers of older, more polluting vehicles £12.50 per day, was credited by the Mayor with reducing NO2 emissions, a pollutant primarily emitted by diesel vehicles.

Who is the unnamed buyer?

The charity Asthma + Lung UK,which collaborated on the analysis, called for transparency and consistency in monitoring approaches to ensure that pollution hotspots are not overlooked.

Residents and health advocates are calling for immediate action to address the gaps in monitoring and to ensure that all areas of the city meet safe air quality standards.

The debate highlights the need for a more comprehensive and localized approach to air quality monitoring, as current methods may underestimate the true extent of pollution.

What auditors flagged in the May filing

The discrepancy between national and local data underscores the complexity of measuring pollution and the importance of using multiple data sources to paint an accurate picture.

Without reliable data, communities cannot make informed decisions about their health and environment.

As London continues to grapple with air quality issues, the demand for cleaner air and greater accountability from policymakers becomes ever more urgent.
