Air quality ranking
The 50 schools in London with the lowest nitrogen dioxide (NO2) levels, cleanest first.
Compare the cleanest-air schools in another region.
Schools in Londonare ranked by nitrogen dioxide (NO2) concentration, lowest first. Air quality data is sourced from DEFRA’s Pollution Climate Mapping model, reporting annual mean concentrations in micrograms per cubic metre (µg/m³). WHO guidelines recommend NO2 levels below 10 µg/m³; the UK legal limit is 40 µg/m³. Each card also shows the school’s retained public-data summary so you can weigh local air against wider published context.
