Toxic Air and Social Justice Event on February 4th 2025

SEM’s CEO Maxwell Ayamba BEM, was invited by Bell Ribeiro-Addy MP: Member of Parliament for Clapham and Brixton Hill, and Chair of the Black Maternal Health Parliamentary Group to the Houses of Parliament, to attend the Toxic Air and Social Justice: The Unequal Burden of Air Pollution Seminar on February 4th 2025.

The event was attended by over 200 people and chaired by Bell Ribeiro-Addy MP with speakers including Rosamund Kissi-Debrah: Founder and Director of the Ella Roberta Foundation, and mother of Ella Adoo-Kissi-Debrah, whose life was tragically cut short by the devastating impact of air pollution. Baroness Jenny Jones: Member of the House of Lords and Sponsor of the Clean Air (Human Rights) Bill, also known as Ella’s Law, Siân Berry MP: Member of Parliament for Brighton Pavilion and the Green Party’s lead on air pollution, L’myah Sherae: CEO of Enact Equality and responsible for leading a national campaign against racial injustice and air pollution and Anna Garrod: Director of Policy, Influencing and Change at Impact on Urban Health.

The event was also attended by journalists from Sky News, BBC News, The Guardian, Metro, and The Independent, as well as representatives from Prime Minister Sir Keir Starmer’s Office.

The turnout was a powerful reminder of how deeply the issues of air pollution and racial justice resonates with communities impacted by air pollution. That led to the Enact Equality’s Racial Justice Campaign for Clean Air petition calling on the Labour Government to take urgent action to address the health inequalities caused by toxic air pollution.

SEM’s CEO in his contribution at the event highlighted the fact that people in marginalised communities have no idea the correlation between the air they breathe and the health impact that many are experiencing. He pointed out that not until SEM took groups out to the Peak District National Park that the difference in air quality is often noticeable.

Maxwell pointed out at the event that SEM often used the Imperial College’s Open Air Laboratories (OPAL) field guides and workbooks to take groups outdoors irrespective of age, background and education to use natural indicators such lichens to help identify types of lichens that are nitrogen dioxide insensitive and thus indicating high levels of air pollution e.g., in areas such as Tinsley near the M1. He told the gathering that the OPAL Explore Nature initiative is a well placed nation wide citizen science project that can be rolled out, and implored the Government to support practical methods that would empower marginalised communities groups to become aware of the impact of air pollution in their communities and to take action.

Supported by Jenson Grant from SEM, Mawell took a group of conference attendees on a 60 minute walk that began at the conference venue and went along some of the city centres’ most congested roads. Attendees used citizen science air quality investigation methods to look for lichens growing on tree bark, which are indicators of air pollution. Trees that have large numbers of Nitrogen insensetive Lichens on their bark indicate that they may be growing in areas with high levels of air pollution.


Maxwell said; “SEM’s work using the Imperial College’s Open Air Laboratories (OPAL) is innovative and impactful in the sense that, unlike Sheffield City Council stationing air monitoring diffusion tubes to monitor the impact of air pollution in communities by taking readings however, this data is not visually shared and therefore difficult to evidence and communicate to educate communities in these polluted zones. However, in the case of SEM applying OPAL Explore Nature Air Quality Survey using natural indicators such as nitrogen-loving lichens it is able to demonstrate the impact of air pollution visually in the most polluted zone across the city”.
