Clean-air score
80/100
Strong baseline with episodic wildfire-smoke pressure.
Primary pollutant watch
PM2.5 (smoke)
Wildfire smoke is the main PM2.5 driver in recent years.
Policy context
Strong
Clean-air policies support a healthy baseline.
Toronto air quality data table
This HTML table mirrors the visible score cards so important comparison data is never trapped in a browser-only chart.
| Metric | Value | Context |
|---|---|---|
| Clean-air score | 80/100 | Trans-regional smoke events drive most exposure spikes. |
| Primary pollutant watch | PM2.5 (smoke) | Indoor-air strategies and air-quality alerts matter on smoke days. |
| Policy context | Strong | Smoke-event preparedness is rising in importance. |
Air Quality city comparison
A crawlable comparison across every indexed city makes it easy to scan how this module changes between metros.
| City | Score | Summary |
|---|---|---|
| Toronto (this page) | 80/100 | Toronto has solid baseline air quality with episodic wildfire-smoke events as the main exposure spike. |
| Copenhagen | 88/100 | Copenhagen performs well on clean-air context, helped by compact mobility, regional monitoring, and strong European air-quality governance. |
| Sydney | 82/100 | Sydney has strong baseline air quality with episodic wildfire-smoke and bushfire events as the main exposure pressure. |
| Singapore | 80/100 | Singapore performs well on clean air with periodic regional haze events as the main exposure pressure. |
| Berlin | 80/100 | Berlin's air-quality profile benefits from strong European monitoring and ongoing transit and street redesign. |
| Tokyo | 78/100 | Tokyo's air profile benefits from strong governance but still requires attention to fine particles, ozone, and heat-related exposure. |
| Paris | 76/100 | Paris benefits from European monitoring and mobility reform, while PM2.5, nitrogen dioxide, and ozone remain key health signals. |
| London | 75/100 | London's clean-air policy has improved exposure trends, with PM2.5 and nitrogen dioxide remaining the key health signals. |
| New York | 72/100 | New York has extensive monitoring and policy capacity, but particulate and ozone exposure remain important health signals. |
Explanation
Air-quality scoring weighs baseline pollutant exposure with episodic wildfire-smoke pressure. Toronto's baseline is healthy; smoke events drive most spikes.
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.
