The World Health Organization (WHO) has today released air quality data for 1600 world cities across 91 countries. In the press release accompanying the data release WHO explained that:
- Only 12% of the people in cities covered live within WHO’s recommended air quality guideline levels.
- About half of the urban population being monitored is exposed to air pollution that is at least 2.5 times higher than the levels WHO recommends – putting those people at additional risk of serious, long-term health problems.
- In most cities where there is enough data to compare the situation today with previous years, air pollution is getting worse.
