In an inspiring report analyzing the air quality of 100 cities around the globe, it has been revealed that 19 cities have made remarkable strides in improving their air quality since 2010.
Among these success stories, nine cities are located in China and Hong Kong, while the remaining are dispersed across Europe, showcasing a mix of both large and small urban areas.
Notably, in the United States, San Francisco has achieved significant reductions in harmful fine particulate matter (PM2.5) as well as airway-irritating nitrogen dioxide (NO2). PM2.5, which consists of tiny particles measuring just 2.5 micrometers in diameter, poses a health risk and is linked to various diseases, including asthma and Alzheimer’s, throughout a person’s lifetime.
Cecilia Vaca Jones, the newly appointed executive director of Breathe Cities, one of the organizations behind the report, stated, “This report demonstrates that cities can accomplish what was once deemed impossible: reducing toxic air pollution by 20-45% in just over a decade.” She emphasized that this transformation is not limited to one region, with cities from Warsaw to Bangkok showcasing that we possess the necessary tools to tackle this crisis now.
The success of these 19 cities can be attributed to a variety of effective measures. Initiatives included transitioning from internal combustion engine vehicles to electric alternatives, expanding bike lanes in bustling European cities, and implementing restrictions on wood-burning stoves and fossil fuel power plants within urban areas.
Among the standout cities, Beijing and Warsaw achieved the highest reduction in PM2.5, slashing levels by over 45%. Meanwhile, Amsterdam and Rotterdam excelled in reducing nitrogen dioxide by more than 40%. San Francisco recorded a commendable 20% reduction in both pollutants.
European cities predominantly focused on shifting to clean energy sources, leading to more significant reductions in PM2.5, whereas cities in China and Asia made greater strides in lowering NO2 levels due to a strong emphasis on replacing traditional vehicles with electric ones.
