Citizen Science - become a citizen scientist!

We have a programme of citizen science for communities to measure air pollution in their neighborhood. We provide information, support and resources for groups to carry out their citizen science projects. These projects encourage participation in civil society, create knowledge, and build capacity in communities.
Citizen science allows people to explore their environment, discover things about it and also about science too. We measure the levels of nitrogen dioxide air pollution in these citizen science projects. Gas diffusion tubes are used which are also used by many local authorities in the UK and elsewhere. The main source of nitrogen dioxide pollution in most urban environments is vehicle emissions especially from diesel combustion engines.
We publish a short guide to using gas diffusion tubes (PDF) which is intended for groups undertaking projects with us but maybe of interest to others.
Citizen Science Programme 2021
In 2021, we're continuing with our citizen science programme. If you'd be interested in one where you live then please contact us.

Initially, they decide where to install diffusion tubes for measuring air pollution and mark it on a map, and then they put them up. [right photo] Elena demonstrates how easy it is! (Note: CAM005 is the designation of the diffusion tube shown.)
In 2016, we worked with several community groups and individuals:
- January St Ebbe’s New Development Residents Association, Oxford; Central Charlton Residents Association, London; Enderby Wharf (Greenwich), London; Slade Green Environment Forum (London borough of Bexley).

Citizen Science Programme 2015

Photo: It starts with a plan! Residents of Lewisham in London started a citizen science programme in January 2015. Initially, they decide where to install diffusion tubes for measuring air pollution.
In 2015, we worked with several community groups:
- Groups opposed to the proposed Silvertown Tunnel (a new road tunnel under the Thames in London between Greenwich and Newham) in South East London, including No to Silvertown Tunnel; East Greenwich Residents Association; Westcombe Society; Charlton Central Residents Association & Slade Green Community Forum. You can find out more about them from the presentations at the Clean Air Convergence, July 2015.
- A Better Lee Green who are concerned about the inappropriate redevelopment of a neighbourhood shopping centre, The Leegate at Lee Green in Lewisham, London. More information
- Sailsbury Clean Air Network, an alliance concerned about poor air quality in Sailisbury, Wiltshire which included Salisbury Green Party. See article from Sailsbury Journal
- Stop the Almond Brook Link Road (SABLR). This was a repeat of an air pollution survey in 2014 with a community group in Standish, Wigan that opposed a proposed link road.
- Manchester Friends of the Earth and Hulme Residents from the Redbricks Estate in Manchester. See the project details and results on the website of Manchester Friends of the Earth
- Camdem Green Party who are concerned about unacceptable air pollution levels in the London borough of Camden and beyond. A workshop was held at the Clean Air Gathering in October with them and other residents. The results of their project are to be published in 2016.

Citizen Science Programme 2013
This citizen science programme started in April 2013 with communities of place - inside and outside London, and communities of interest - owners of the Air Quality Egg (a digital air pollution monitor), and shops owned by Lush.
