About Breathe London

Breathe London plays a crucial role in helping local communities, schools, hospitals and Londoners understand air pollution and take action to reduce their exposure.

Breathe London measures air quality across the city, making air quality data available to the public, and is engaging with hospitals, schools and local communities to champion action on air pollution.

There are many ways for our network of local authorities, schools and hospitals to get involved in the programme. From the Breathe London newsletter, our working groups for sensor holders that meet monthly, webinars, resources hub and helpdesk, we’re here to help you use the data from your sensor to take action to make the air in your community cleaner and safer to breathe.

The programme is brought to you by a consortium of partners, bringing together leading air quality technology, data and engagement expertise.

Our Partners:

Vodafone

Consortium lead and platform for air quality sensor network expansion (infrastructure and environmental data).

Vodafone business logo

Vodafone, as the lead for this partnership, brings its “Network as a Sensor” offering for scaling Breathe London. Vodafone’s global connectivity, the opportunity to utilise its network infrastructure to host additional sensor locations, and its wider portfolio of environmental data are all key enables to expand Breathe London both geographically and with additional data and insights.

Vodafone believes that connectivity is a force for good, and if we use technology for the things that really matter, we can improve our lives and the world around us.

Global Action Plan

Global Action Plan logo

Global Action Plan mobilises people and organisations to take action on the systems that harm us and our planet. Through our work we create the political and policy conditions for more radical action, connecting behaviour change to systems change. Our cycle of change involves three connected steps that influence systems change through mobilisation:

Mayor of London

Breathe London was established by the Mayor of London. The Mayor’s vision is for London to have the best air quality of any major world city by 2050, going beyond the legal requirements to protect human health and minimise inequalities. The Mayor is taking action to reduce the exposure of Londoners to harmful pollution, mobilising action from London boroughs, and working to meet World Health Organization health-based interim guidelines for air quality by 2030.

In partnership with Mayor of London

Breathe Cities

Breathe Cities is a first-of-its-kind initiative delivered by the Clean Air Fund, C40 Cities and Bloomberg Philanthropies to clean our air, cut carbon emissions and enhance public health in cities around the world. Inspired by pilots in Warsaw and London, Breathe Cities aims to tackle urban air pollution on a global scale, with programmes now running in 14 cities worldwide. It brings together air quality data, communities and city leaders in its mission to reduce air pollution and planet-warming emissions by 30% across participating cities by 2030. Achieving this 2030 goal would prevent an estimated 55,000 premature deaths and around 111,000 new cases of asthma in children, save $147 billion in avoided hospitalizations and deaths and avoid up to 394 megatonnes of CO2e emissions.
