Helping authorities meet air quality targets
We assist local authorities, councils and government agencies in improving localised air quality — focused on AQMAs, ULEZ zones and pollution hotspots, where impact matters most.
Roadvent captures the dirtiest concentrations of airborne pollutants at the closest possible point to the source — before they disperse and are inhaled — significantly reducing the roadside pollutant levels used to measure public sector air quality.
The 91% figure was measured at the experimental site at UTAC Millbrook Proving Ground. See the test reports.
Local authorities face growing requirements under the Environment Act, Air Quality Standards Regulations and Defra compliance directives to deliver measurable reductions in roadside pollution.
Roadside NO₂ and PM2.5 limits are moving towards WHO guidelines, so borderline-compliant corridors risk falling back into non-compliance. The question is shifting from whether to intervene to how fast compliant solutions can be deployed — without disrupting mobility or the economy.
Baring Road Primary School — a Roadvent case study with Lewisham Council.
Planning permission has been granted for Lewisham Council's Roadvent pilot trial at Baring Road, funded and supported by the Mayor's Air Quality Fund and delivered with support from Pollution Solution. Lewisham will be the first council in the UK to install such a system.
The school sits within an Air Quality Management Area and an Air Quality Focus Area. Traffic queues outside and nearby reduce air quality for children in the playgrounds and classrooms — exactly the kind of hotspot Roadvent is built for.
Discreet green Roadvent extraction slots in the carriageway, and an air handling cabinet inside school grounds behind an existing brick wall — so the footpath keeps its full width and the visual impact stays low.
A detailed acoustic assessment found low noise impact, and additional independent air-quality monitoring is already in place to validate the system's performance.
Often sited near busy roads, with playgrounds and pick-up/drop-off points exposed at peak rush hour. Roadvent suits zebra crossings and school-gate installations well.
Junctions, crossings, street canyons and congested roads. Proven to reduce exposure to vehicle emissions at the roadside and in-car from the vehicle ahead.
Idling and queuing vehicles create concentrated toxic pockets. Modular sections tailor coverage to any length of roadway.
Stationary queuing at barriers and booths generates significant brake, tyre and exhaust emissions, affecting residents, pedestrians and drivers alike.
Railvent targets particulate pollution in platform hall areas on underground rail networks, where emissions from rail operations build up and cannot disperse.
Tunnelvent filters the air at road tunnel ventilation outlets before it is released into the surrounding neighbourhood.
