Cleaner Air 4 Communities:  London

Air pollution is one of the greatest health challenges facing our cities with London being one of many UK cities failing to meet yearly legal pollution limits. As the government is currently developing new legislation to reduce the risk of air pollution, the aim of this project is to enable the communities that are most affected by pollution to have their voices heard and support them in influencing policy.

In East London, the borough of Tower Hamlets is particularly at risk with over 40% of the population exposed to an illegal average annual concentration of NO₂. LSx will be working in partnership with the Royal Society of Chemistry to train East London communities on the science of air pollution and what actions can be taken to ensure air pollution is reduced in the local area.

Previous Work

  • Our Cleaner Air work throughout London has played a vital role in ensuring pollution has a higher political priority in London.


  • The Cleaner Air 4 Communities: England project has hosted similar air pollution planning and citizen science events throughout the UK in Birmingham, Southampton, Leeds, Nottingham and Derby.


  • Last year we helped local community air quality coalitions to form, supporting over 100 clean air champions in Brent, Camden, Croydon and Hackney. These champions form the foundation for the Clean Air Network in London and as a collective can create larger scale change.

 Hiri Sensors

  • As part of our Cleaner Air for Communities project we are teaming up with the scientists at Hiri to pilot 30 sensors­­ around London. Community members will be assisted by atmospheric chemistry volunteers to collect PM2.5 data. Passive diffusion tubes will be used to take NO2 measurements.


  • The project aims to educate and raise awareness surrounding pollution through planned experiments throughout the neighbourhood.


  • The sensors are linked to the user’s smartphones where they will then be automatically entered into the central database at Hiri. The project will allow the data to be mapped onto a spatio-temporal image to allow scalar visualisation of pollution hotspots.


  • For more information about the sensors visit the Hiri website. An overview of how the sensors work, along with experimental design information can be found here.

  Get Involved

Take part in our citizen science training with access to teaching from expert chemistry academics. This will enable you to conduct experiments which will show where the areas of high pollution are and allow you to speak more confidently about the science of air pollution.  Your findings can then be used to create a personalised action plan as well as influence the action taken by policy makers.
Attend local events, to learn more about pollution in your local area and how you can take action – contact us to find out when and where they are happening in London!
Sign up to our e-bulletin which will include project updates, air quality news and handy tips on fighting air pollution
