Air quality monitoring technology developer EMSOL has launched a collaboration with Transport for London (TfL) and Paris’s RATP Group testing specialised sensors for underground transit environments.
The initiative will deploy the EMSOL Praxis air quality instruments across five key metro stations – Baker Street, Tottenham Court Road, and Hampstead in London, and Auber and Jaures in Paris – serving transport systems that collectively carry approximately 8 million passengers daily.
The one-year project will be funded by EIT Urban Mobility (part of the European Institute of Innovation and Technology).
During this time, the partnership will seek to harness EMSOL’s monitoring expertise with the operational knowledge of TfL and RATP Group, supported by research from Imperial College London.
The project will follow a two-phase approach: initial deployment of existing monitoring equipment alongside reference instruments, followed by development of enhanced sensors specifically engineered for the distinctive conditions of underground environments.
CEO of EMSOL Freddie Talberg said: “Underground air quality presents unique monitoring challenges compared to surface environments.
“By partnering with two of Europe’s busiest metro systems, we’re developing technology that could benefit the health of millions of daily commuters worldwide.”
Achievements and innovations in air quality will be recognised and celebrated at the fourth annual CiTTi Awards on 25 November 2025 at De Vere Grand Connaught Rooms in London. Visit www.cittiawards.co.uk to learn more about this unmissable event for the UK’s transportation sector!
