Restricting high-emitting vehicles in cities through clean air zones, such as London’s ultra-low emissions zone, not only improves air quality but also gets kids walking and biking to school more. In a study comparing London and Luton, researchers found that 2 out of 5 students in London started using active modes of transportation after the implementation of the zone, while only 1 in 5 in Luton did. These changes have important implications for children’s health, as walking or biking to school can improve physical and mental well-being, academic performance, and prevent obesity. Despite legal obstacles in the US, encouraging active transportation can have numerous benefits for communities and the environment.
