Despite recent attempts to paint the United States as a major global polluter, according to the World Health Organization (WHO), the U.S. is among the cleanest nations on the planet.
In the most recent WHO report on air pollution, the United States was listed as one of the countries with the cleanest air in the world, significantly cleaner in fact than the air in Germany, Italy, Switzerland, the UK, Japan, Austria and France.
While France and other G7 countries lamented the U.S. exit from the Paris climate accord, America’s air is already cleaner than that of any other country in the G7.
Following standard practice, the WHO measures air pollution by the mean annual concentration of fine suspended particles of less than 2.5 microns in diameter. These are the particles that cause diseases of all sorts and are responsible for most deaths by air pollution.
