About air quality in Camden
Camden stretches from the AURN-flagship Camden Kerbside / Swiss Cottage site on the A41 down through Camden Town, Kentish Town, and Bloomsbury to the King’s Cross / Euston transport hub. The Euston Road corridor and the A41 carry the borough’s most persistent NO₂ pressure, and roadside concentrations at Camden Kerbside have historically been among the highest in the UK reference network. Background levels have improved since the ULEZ extension in 2023.
PM₂.₅ across Camden is dominated by regional weather and transport patterns rather than local sources; on most days the borough shares air with Westminster and Islington. Monitoring coverage is dense along the major arterials and weaker in the residential interior (Belsize Park, Dartmouth Park), so the borough-level verdict is most reliable for the central and southern wards.
