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

London’s Ultra‑Low Emission Zone (ULEZ), introduced by Mayor Sadiq Khan in 2019, has dramatically improved air quality and saved lives, a result that former health advocate Alastair Harper attributes to the political courage of a single leader. Harper recalls leaving a meeting when his child was rushed to University College London Hospital in a blue‑lit ambulance because of severe breathing problems caused by the city’s toxic air—a scenario that was all too common for hundreds of thousands of London families in the late 2010s. At that time, between 6,000 and 8,000 premature deaths were recorded each year in the capital, and an inquest in 2020 officially linked the death of Ella Adoo‑Kissi‑Debrah to air pollution, marking the first such finding in the UK. Since the ULEZ’s rollout, the city has seen a marked reduction in harmful pollutants, giving parents like Harper confidence that their children now breathe safer air, a change he credits to Khan’s decisive policy choice.
The health benefits observed in London echo a global consensus that air pollution is a leading cause of disease and premature death, killing roughly 7 million people annually according to the World Health Organization. While sources of pollution differ—coal‑fired power plants in China and India, agricultural burning in Southeast Asia, waste incineration in low‑income nations—the contribution of road traffic is universal. Experts such as Imperial College’s Professor Nick Hopkinson note that the link between traffic emissions and respiratory, cardiovascular, and even neuro‑developmental disorders has long been established, yet many cities still encounter fierce resistance to curbing emissions. This opposition often stems from entrenched interests, cultural attitudes toward cars, and political forces that frame clean‑air measures as economic threats, as seen in the United States where weak public‑transport infrastructure, an entrenched SUV culture, and policy rollbacks under former President Donald Trump have stalled progress.
Other municipalities are attempting to emulate London’s success, though with varying degrees of caution and speed. Bogotá, Colombia, is preparing its second “Zuma” clean‑air zone, expanding cycling infrastructure, paving dusty roads, and planting trees after winning the 2023 Earthshot prize for its first initiative; environment secretary Adriana Soto emphasizes community involvement in design to preserve local mobility. Sofia, Bulgaria, is pioneering a combined transport and heating low‑emission zone in Southeast Europe, phasing out coal and wood heating in favor of subsidised heat pumps, which has already cut PM10 concentrations by 22 % and halved days exceeding air‑quality guidelines. Poland is undertaking similar fuel‑switching measures. Yet, despite these advances, the momentum remains uneven: London’s gains are now threatened by a surge in wood‑burning stoves, and many cities lack the political will or public support to implement rapid, comprehensive reforms, leaving the global fight against dirty air still very much in a tentative phase.
