Air pollution set to exceed limits at four out of five Breathe London sites
Last month Environmental Defense Fund Europe (EDFE) together with Mayor Sadiq Khan are releasing the second wave of data from Breathe London, an ambitious collaborative project to measure and map air pollution across the capital.
In addition to nitrogen dioxide (NO2) measurements from the network’s 100+ stationary AQMesh pods, the interactive map now includes preliminary data from the Google Street view car drives as well as current and average pollution data for fine particulate matter (PM2.5).
The new data confirms a concerning trend: Air pollution across the capital remains dangerously high. Four out of every five pods, including 90% of schools in the network, are on track to exceed World Health Organisation (WHO) annual guidelines for PM2.5, which is linked to a wide range of adverse health effects. Additionally, preliminary analysis of the mobile data shows NO2 is on average over 50% higher on major through roads than quieter, local roads.
