London’s Ultra Low Emission Zone (ULEZ) is transforming children’s journeys to school by making streets safer, improving perceptions of air quality and encouraging children to live healthier lives. A new study published today in BMJ Open, and funded by the National Institute for Health and Care Research (NIHR), highlights its benefits, with many families noticing cleaner air and safer roads. However, it also reveals challenges, particularly for those living in outer boroughs who are more reliant on the car and may struggle to adapt.
The Challenge of Air Pollution
Road traffic is a major source of air pollution in London, posing serious health risks. One in 11 children in the city has asthma, a condition worsened by poor air quality. Car use also limits opportunities for active travel, such as walking and cycling, which help prevent obesity and chronic illness.
Introduced in 2019, the ULEZ charges high-polluting vehicles that enter all London boroughs. According to Transport for London (TfL), it has reduced levels of the pollutant nitrogen dioxide (NO₂) by 53% in central London, 24% in inner London, and 21% in outer London, while also cutting traffic.
