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.

Citizen Science Programme 2019

In 2019, we worked with two groups of citizen scientists: The Red Ballon School, Harrow, North-west London - a follow-up study from the previous year; and Glastonbury Town Council, Somerset - the third annual study which they'd undertaken.

Citizen Science Programme 2018

Some of the groups with which we've worked in 2018:

Citizen Science Programme 2017

In 2017, we worked with several community groups:

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:

In 2014, we worked with two groups in London: one in the borough of Greenwich (No to Silvertown Tunnel), and the other in Deptford - borough of Lewisham (Don't Dump on Deptford Heart).

Outside of London, we worked with a group in Standish, Wigan (Stop the Almond Brook Link Road).

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.
