How do I use the map?

Click the ‘From’ and ‘To’ boxes at the top of the map to input the starting and end points of your journey. The route finder will provide up to three alternative walking or cycling routes, colour coded green, orange and red, which represent the journeys with the lowest, middle and highest concentrations of nitrogen dioxide (NO2) and PM10 and PM2.5 particulates.

Toggle between the walking and cycling icons at the top of the map to see how the routes differ between travelling on foot and cycling.

The coloured routes on the default view of the map represent Clean Air Routes between transport hubs and key pedestrian destinations that have been monitored and identified as being 30% to 60% less polluted than more popular alternatives.
Click on each route for more information.

Zoom in to the map to see air quality represented at the street level, which is coloured co-ordinated with the legend at the bottom of the map. Blues and green representing lower levels of pollution and red and black representing higher levels of pollution.

This data is obtained by the London Air Quality Network (LAQN) which is the most advanced air quality monitoring network in the world. Through a unique combination of monitoring and modelling, King’s College London has created the London Atmospheric Emissions Inventory (LAEI). This sophisticated high-resolution map of air quality details NO2, PM10 and PM2.5 particulate and ozone (O3) concentrations right across the city.

These are routes created by Transport for London to link communities, businesses and destinations across London in one cycle network. They are high quality cycle routes that offer a mix of protected cycle lanes across some of the busier main roads in the capital.

This shows 14 main train stations in central London, with the radials representing the cycling distance that can be covered in both 2 minutes and 5 minutes.

The Walking Tube
These coloured routes represent less polluted streets between closely situated tube stations in central London. Taking a Walking Tube route increases your daily active travel and helps to alleviating overcrowding on some of the busiest tube stations. For more information, visit Transport for London’s Walking Tube map and Cross River Partnership’s Walking Tube report.
