What's new about Breathe London

24/06/25

Over the past few months, our team has been working hard behind the scenes to bring you a brand new, refreshed Breathe London website.

We’ve been chatting to our network of sensor users to find out what you wanted from the new site, and thanks to all your feedback, we’ve introduced:

  • A refreshed map, with live hourly data showing pollution levels in your area. We’ve updated the map so that the circles show more detailed information about pollution levels, to help you to track variations across the city and on your particular sensor. We’ve kept the colour scale, from green (low) to purple (very high), to help you make sense of it.

  • Updated individual sensor pages, where you can get a more detailed view of your air quality sensor, view live data on a new and improved graph, and download historic data.

  • News articles bringing you the latest from Breathe London and sharing stories from across the network.

  • A resource hub, where you can filter to find the most interesting and useful tools to help you take action for clean air (we’ll be adding more content to the hub throughout the programme, so watch this space!)

You can also find out more about Breathe London, the partners who are delivering this phase of the project, and how to get in touch with the team.

Make sure to save us to your favourites so you can easily access your sensor data!
