A health-oriented comparison of city air-quality scores using WHO-centered pollutant interpretation.
Ranking rows link directly to city profile pages, keeping comparisons useful for users and crawlable for search engines.
| Rank | City | Score | Why it ranks here |
|---|---|---|---|
| #1 | CopenhagenDenmark | 88/100 | Strong regional monitoring and low-emission mobility profile. |
| #2 | TokyoJapan | 78/100 | Solid megacity performance with heat and ozone context to watch. |
| #3 | ParisFrance | 76/100 | Improving street and mobility policy, with pollutant pressure remaining. |
| #4 | New YorkUnited States | 72/100 | High monitoring confidence, but PM2.5 and ozone remain health signals. |
The clean-air ranking emphasizes PM2.5, PM10, nitrogen dioxide, ozone, monitoring confidence, and policy context.
Rankings are directional intelligence, not official government scores. Each entry links to a city profile where users can inspect module-level context, source blocks, and data tables.
These pages use trusted institutional references for methodology and context. Mock values are typed and ready to be replaced by API-backed city datasets without changing route structure.
Used to normalize air-quality indicators toward health-protective benchmarks.
Used where European city comparisons need monitored air-quality context.
Used where United States city comparisons need air-quality benchmark context.
