Summary:
- The article discusses the impact of London's Ultra Low Emission Zone (ULEZ), an anti-pollution scheme that charges drivers of older, more polluting vehicles to enter certain areas of the city.
- The data shows that the ULEZ has been most effective in reducing air pollution in the London boroughs that initially opposed the scheme, suggesting that it has been successful in targeting the areas with the highest levels of pollution.
- The findings highlight the potential of targeted policies like the ULEZ to improve air quality in urban areas, even in the face of initial opposition from local authorities.
