Mayor's Air Quality Fund

The latest successful project round was announced by the Mayor on 9 March 2024.

This fourth funding round supported seventeen projects to reduce particulate matter (PM_2.5) emissions, run more sustainable events and improve indoor air quality. This protects vulnerable Londoners from pollution, in places like schools and hospitals.

Projects include:

• Healthy Waterways: a 14-borough collaboration, delivering strategies and a toolkit for local authorities to tackle emissions from boats on canals and rivers.
• Idling Action Project: a 20-borough collaboration, reducing commercial sector vehicle engine idling by engaging with fleet operators, driving instructors, and policymakers.
• Zero Emission Network: a Hackney, Tower Hamlets, Newham and Westminster collaboration, supporting businesses and residents to adopt cargo and e-bikes for deliveries and work travel.
• Non-Road Mobile Machinery (NRMM) Beyond Construction: a pilot scheme, looking at NRRM impact on roadworks, licensed events, and waste sites. Outcomes show London boroughs how to reduce NRMM emissions.
• Healthy Streets Everyday Phase II: a six-borough collaboration, with business improvement district and strategic partner support. This looks at increasing active travel, walking routes, school streets, low emission transport infrastructure, and green space improvements.
• London Woodburning Project: a project creating a Londonwide training scheme, enforcing smoke control areas for borough officers while building on previous project success to reduce wood burning emissions.
• Kilburn High Road Improvement Scheme: a Brent project, improving urban realms along Kilburn High Road. Introducing 20mph speed limits, better pedestrian access, improved street lighting, new street furniture, and new cycle parking.
• Clean Air for Camden: a Camden community engagement project, spreading air quality awareness while encouraging residents to reduce exposure to indoor and outdoor pollution.
• Cleaner Filming for Camden: a Camden project, researching and quantifying air quality emissions impact from NRMM on film sets, encouraging cleaner film productions.
• Tackling Dirty Air at Primary Schools: a Hammersmith and Fulham project, introducing timed pedestrian and cycle zones, indoor air quality filters, and green screens at four schools to reduce student poor air quality exposure.
• Road Vents: a Lewisham project, trialling and assessing innovative new road vent technology outside schools, reducing student road traffic emissions exposure.
• Schools and Asthma: a Southwark project, raising awareness and driving behaviour change across 25 schools, reducing pollution impact on students with asthma.
• School Super Zones Consolidation: a Tower Hamlets project, expanding School Super Zones. This engages children in air quality improvement planning and delivery at school, including air quality monitors and filters.
• Inequalities of Indoor Air Quality in Westminster Homes: a Westminster project, using cutting-edge indoor air quality monitors to study links between indoor air quality, health, and socio-economic inequalities.
• Trafalgar Square Power Upgrade: a project increasing electrical supply at Trafalgar Square, to reduce generator use during public events.

Previous funding rounds have supported a wide activity range, including:

• an anti-idling campaign across several London boroughs
• green courier services and initiatives
• infrastructure to enhance walking and cycling
• projects to reduce emissions from construction
• Low Emission Neighbourhoods.
