London’s low emission zone is working – so why are cities around the world so cautious about clean air?

Ten years ago in London, Alastair Harper, a children's health advocate, experienced a personal crisis when his child was rushed to UCLH hospital via ambulance, struggling to breathe London's toxic air. This event underscored the urgency of air pollution issues, as Harper had been in a meeting planning an air pollution campaign when he received the call. The article highlights that similar low emission zone initiatives, like London's, are being adopted globally from Barcelona to Bogotá, but often face significant opposition from misinformation, political pressure, and vested interests. The piece questions why other cities remain cautious about implementing clean air policies despite the proven success of London's low emission zone in improving air quality and public health.
