City of London launches interactive Air Quality Dashboard to inform citizens on air pollution
As part of Clean Air Day 2026, Greater London Authority developed an interactive air quality dashboard that allows for the city's residents and the general public to explore and visualise air pollution data, current and past trends, and related environmental initiatives.
London operates one of the world's most extensive ambient air quality monitoring networks, with more than 100 reference stations complemented by city-wide network of low-cost sensors and diffusion tubes tracking long-term trends in nitrogen dioxide (NO₂) and fine particulate matter (PM2.5 and PM10) concentrations across the city which are part of the Breathe London network and Breathe London Communities, two pioneering initiatives providing detailed, street-level data across the capital. This online air quality dashboard consolidates all of this information into a single, easy-to-use platform displaying air pollution levels and showing how policies introduced by London are expected to influence air quality. The dashboard highlights the impacts of measures such as the Ultra Low Emission Zone (ULEZ), fast deployment of electric vehicle charging points and school-focused clean air programmes.
Keeping citizens informed
The dashboard is intended to provide residents, researchers and policymakers with easier access to environmental information and to support efforts to achieve cleaner air. While London's air quality has improved significantly since 2016, there are still many areas that exceed the stricter air quality guidelines recommended by the World Health Organization. London's long-term ambition is to become the major world city with the best air quality by 2050. Recent policies have enabled the capital to meet legal limits for nitrogen dioxide far earlier than previously forecast, but further action will be needed to reduce harmful particulate pollution and meet tougher health-based targets.The dashboard forms part of a broader strategy to make environmental data more accessible and to help Londoners understand the impact of air quality measures on their communities.
Beyond air quality, a broader climate ambition
Beside the city's efforts in making it's residents stay informed about the levels of air pollution, London is also committed to global and local climate action - from 20 to 28 June 2026, the city will host the Climate Action Week, an event bringing together more than 75,000 people (policymakers, businesses, cities, scientists, civil society, youth and communities) across more than 1,000 events over nine days. From community gatherings in every London borough to major international conferences, ministerial roundtables and public art installations, LCAW has become a major platform to accelerate climate action by fostering collaboration, creating space for ideas, partnerships and practical solutions that drive ambition and implementation worldwide.
