Introducing Ulez was my hardest decision as mayor of London – but now we know its astonishing impact | Sadiq Khan

London's Ultra-Low Emission Zone (Ulez) has had a significant impact on the city's air quality and health of its residents. A recent study found that children in London are now breathing cleaner air, resulting in improved lung size and function. This outcome is a direct consequence of Mayor Sadiq Khan's decision to introduce Ulez, which aimed to reduce pollution levels in the city. The success of Ulez demonstrates the effectiveness of policies aimed at improving public health and reducing environmental pollution.

The introduction of Ulez has reduced pollution levels in London, which is a positive development for the city's residents. This reduction in pollution can have long-term health benefits for the population, particularly children.
