Air pollution is improving in many cities. That’s according to the Breathe Better report. The report was released on March 11. It was published by Breathe Cities. That’s a global program. It’s trying to “help cities clean the air and protect public health,” the Breathe Cities website says.

The report lists 19 cities in Asia, Europe, and North America. Each has reduced two types of air pollution by at least 20% since 2010.

Beijing, China, is one of the cities. Officials there created an air quality monitoring network. Paris, France, improved bike lanes. In San Francisco, California, a new air pollution map keeps residents informed.

Air pollution is still “the largest environmental health risk,” according to the report. Data from the World Health Organization shows that 99% of people breathe air that contains a high level of pollution. But the Breathe Cities report affirms that “city leadership can drive rapid and sustained improvements” in air quality.
