A year after London's clean air zone was enforced, 40% of children began walking or biking to school instead of being driven, according to new research.
Syris Valentine reports for Grist.
In short:
- A study found that 40% of kids in London's ultra-low emissions zone switched from car rides to walking or biking within a year of the policy's start.
- In contrast, only 20% of children in the control group city, Luton, made the same switch, with an equal number starting to drive.
- Researchers say this shift could combat childhood obesity and improve both mental and physical health.

"Physical activity in general is vital for preventing obesity... and has benefits for children’s physical development and mental health.”

Why this matters:
Research shows that penalizing driving—rather than just building bike lanes or walking paths—is often more effective at getting people out of their cars. And whether it's through incentives or penalties, the takeaway is clear: what’s good for the planet is often what’s best for the kids too. Read more: Another road is possible.
