On the European Air Quality Index website you can follow the up-To-Date air quality levels and forecasts across Europe.

761 European cities are also ranked by the health risk from long-term exposure to three key pollutants: fine particulate matter, nitrogen dioxide and ground-level ozone, averaged over the past two calendar years. Population matters here in a specific way: pollution levels are weighted by where a city’s inhabitants live, so the ranking reflects the air an average resident is actually exposed to, rather than raw pollutant readings. Long-term exposure is the focus because it causes the most serious health effects. A new feature this year — you can also explore longer-term air quality trends for individual cities or groups of cities monitored in the EU.
So where does your city stand, and why?
