Quick answer

What does Cities with the lowest annual NO2 show?

Ronneby, Sweden has the lowest no₂ — annual mean of the 30 cities compared: 1.72 µg/m³ (Official exact-kommun station observations are derived to a kommun aggregate., 2024).

How this list is built

Every row is a published no₂ — annual mean observation, ranked lowest first. The values were observed between 2023 and 2025. A place appears only when it publishes this exact metric, so an absent place means missing data rather than a low value. Only published cities with at least 20,000 residents and city-level observations qualify.

  • Compare the displayed value, unit, source date and geographic grain together.
  • A city label does not change a regional observation into a city measurement.
