Air quality on some of the busiest routes in Brighton & Hove is improving, our latest figures show.
Data collected citywide show that Nitrogen Dioxide (NO2) levels have fallen by around a third in the last ten years. But there have been bigger NO2 reductions in several key areas, including from the city’s six Air Quality Management Areas (AQMAs) for example:
