London's ULEZ: Transforming School Journeys and Cleaner Air

**London's Ultra Low Emission Zone (ULEZ)**, introduced in 2019, is significantly transforming children's journeys to school by making streets safer and air cleaner, as indicated by a recent study published in BMJ Open. The study, part of the Children's Health in London and Luton (CHILL) Study, shows that ULEZ has shifted 42% of children from car to active travel modes like walking and cycling. **Transport for London (TfL)** reports a considerable reduction in nitrogen dioxide levels: 53% in central London, 24% in inner London, and 21% in outer London. As road traffic is a key pollution source, the ULEZ aims to curb health risks such as childhood asthma. Families and teachers observe health improvements and reduced traffic congestion, making active travel more appealing and enjoyable. However, the study highlights challenges, especially in outer boroughs where car reliance is higher. The scrappage scheme offers limited support for transitioning to compliant vehicles, while public transport remains costly and poorly connected. **Dr. Olivia Alliott** from the **Medical Research Council (MRC)** notes the importance of policies like ULEZ in promoting healthier travel but stresses the need for equitable access to alternatives. The research advocates for investments in affordable, connected transport options to ensure all demographics benefit equally. The findings offer valuable insights for global policymakers considering similar initiatives to improve public health and air quality.
