Air Quality score

Health-oriented air-quality conditions with context from WHO, EEA, and EPA benchmarks.

Air Quality in Tokyo78/100

Clean-air score

Good

78/100

Solid air-quality score for a megacity, with health benchmarks still relevant.

Main exposure concern

PM2.5 and ozone

Dense urban activity keeps fine particles and ozone in the model.

Exposure modifier

Heat

Heat can amplify health risk and should be read alongside pollutant levels.

Explanation

The air-quality model gives large dense cities credit for governance while still penalizing exposure patterns that matter for health.

Read this module with the main city profile because single-topic pages can miss tradeoffs. A city with a high energy score can still have housing pressure, and a city with strong opportunity can still carry health exposure risk.
