Case Study: Biodiversity & environmental qualityCutting the emissions from air quality monitoring
Nitrogen dioxide (NO₂) is a harmful air pollutant mainly from traffic and fossil fuels. It worsens respiratory health, contributes to smog and acid rain, and forms fine particles and ozone. NO₂ is a key indicator of urban air pollution and a target for clean air and sustainability policies. As part of Lambeth’s commitment to improving air quality, we use diffusion tubes to monitor nitrogen dioxide levels around the borough. To collect these samples, we work with Gophr, who collects and replaces over 120 samples monthly using bicycle couriers, making sure our monitoring project doesn’t contribute to poor air quality.
