Policy momentum
Strong
Ultra-low-emission policies support continued improvement.
London 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 | 75/100 | Trend is favorable; absolute exposure still matters. |
| Primary pollutant watch | PM2.5 and NO2 | Traffic-corridor exposure shapes the pollutant profile. |
| Policy momentum | Strong | Mobility transition reinforces clean-air progress. |
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 |
|---|---|---|
| London (this page) | 75/100 | London's clean-air policy has improved exposure trends, with PM2.5 and nitrogen dioxide remaining the key health signals. |
| Copenhagen | 88/100 | Copenhagen performs well on clean-air context, helped by compact mobility, regional monitoring, and strong European air-quality governance. |
| Zurich | 88/100 | Zurich performs strongly on clean air, supported by compact transit-led mobility and rigorous European monitoring. |
| Auckland | 86/100 | Auckland has strong baseline air quality, supported by coastal context and comparatively low pollutant exposure. |
| Amsterdam | 85/100 | Amsterdam performs well on clean air, supported by compact mobility patterns and European monitoring depth. |
| Vienna | 84/100 | Vienna's clean-air profile is strong, supported by compact transit-led mobility and continuous European monitoring. |
| 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. |
| Toronto | 80/100 | Toronto has solid baseline air quality with episodic wildfire-smoke events as the main exposure spike. |
| Tokyo | 78/100 | Tokyo's air profile benefits from strong governance but still requires attention to fine particles, ozone, and heat-related exposure. |
| Barcelona | 78/100 | Barcelona's clean-air profile is improving with mobility reform, while traffic-related and regional pollutants remain health-relevant. |
| San Francisco | 78/100 | San Francisco has a healthy baseline air profile, with episodic wildfire-smoke events as the main exposure pressure in recent years. |
| Cape Town | 78/100 | Cape Town has solid baseline air quality, with episodic regional and biomass-burning events as the main exposure spikes. |
| Paris | 76/100 | Paris benefits from European monitoring and mobility reform, while PM2.5, nitrogen dioxide, and ozone remain key health signals. |
| New York | 72/100 | New York has extensive monitoring and policy capacity, but particulate and ozone exposure remain important health signals. |
| Seoul | 70/100 | Seoul's air-quality profile is improving with policy attention, while particulate exposure from regional and seasonal sources remains a key health signal. |
| Hong Kong | 70/100 | Hong Kong's air-quality profile is improving with policy attention, while particulate and ozone exposure remain key health signals. |
| Dubai | 65/100 | Dubai's air-quality profile is shaped by desert-dust events and traffic-related pollutants, with monitoring and indoor-air strategies as key practical inputs. |
| São Paulo | 65/100 | São Paulo's air-quality profile is shaped by traffic-related pollutants and seasonal regional sources, with active monitoring and policy attention. |
| Nairobi | 64/100 | Nairobi's air-quality profile is shaped by traffic-related pollutants and dust, with monitoring depth and policy attention rising. |
| Bangkok | 60/100 | Bangkok's air-quality profile is shaped by seasonal particulate exposure and traffic-related pollutants, with policy attention rising. |
| Mexico City | 58/100 | Mexico City's air-quality profile is shaped by particulate, ozone, and altitude factors, with long-running policy attention and steady improvement. |
Interpretation
Air-quality scoring weighs pollutant exposure against monitoring confidence and policy momentum. Clean-air zones build long-run improvement. Across the indexed cities the air quality average is 76/100, so London is close to the median for this dimension. Data year 2025; last updated 2026-05-05. Drawn from 2 institutional references.
