Breathe London

Breathe London

Summary: 100 AQMesh pods are used as stationary monitoring points in the groundbreaking Breathe London project; a hyperlocal air quality monitoring network providing a real-time map of air pollution across the city.

Location: London, UK

Date: July 2018 - Present

Customer: C40 Cities Climate Leadership Group / Environmental Defense Fund Europe

Objective: To map air pollution at an unprecedented level by collecting real-time air quality data throughout London, enabling authorities to evaluate the impact of air quality and climate change policies and develop responsive interventions. The outcome of the project will be a "revolutionary air monitoring model and intervention approach that can be replicated cost-effectively across other UK cities and globally."

Deployment: 100 AQMesh pods are installed at different locations throughout London monitoring levels of key air pollutants including nitrogen dioxide (NO2) and fine particulate matter (PM2.5) in near real-time, in addition to two Google Streetview cars equipped with air monitoring equipment. The data being collected is being published by the Breathe London project on their live interactive map of pollution levels across London.

Results: So far air pollution across the capital remains dangerously high. Four out of every five AQMesh pods, including 90% of schools in the network, are on track to exceed World Health Organisation (WHO) annual guidelines for PM2.5. Preliminary analysis of the mobile data shows NO2 is on average over 50% higher on major through roads than quieter, local roads.
