19 global cities, including London, San Francisco, and Beijing, have reduced air pollution by over 20% since 2010.
Interventions like cycle lanes, electric car adoption, and vehicle restrictions contributed to the improvements.
Beijing and Warsaw reduced PM2.5 levels by over 45%, while Amsterdam and Rotterdam cut NO2 by over 40%.
San Francisco was the only US city to reduce both pollutants by over 20%.
China and Hong Kong account for nine of the 19 cities, with European cities making up the rest.
The report highlights the effectiveness of policies like China's shift to electric cars and London's dirty vehicle restrictions.
Air pollution poses severe health risks, including cognitive decline, heart disease, and respiratory issues.
No safe levels of PM2.5 exist, but following WHO guidelines could save millions of lives annually.
The report emphasizes that bold policies can significantly improve air quality within 15 years.
