Every year I check up on the Beijing air quality based on the U.S. Embassy monitor (which goes back to 2008). Looks like 2022 was another year of improvement, with several monthly avgs hitting new lows. The annual avg has improved by almost half since 2017, the end of the official War on Air Pollution. (Note that the colors do not imply good air quality.)
