Early findings from an evaluation of Bradford’s Clean Air Zone suggest the scheme is associated with improvements in air quality and reductions in healthcare use, leading to cost savings for the NHS.
The study, conducted as part of the ActEarly research programme, examined changes in nitrogen dioxide (NO₂) levels and health service use over a 24-month period following implementation. Using an interrupted time series analysis, researchers found evidence of reduced air pollution alongside changes in healthcare utilisation consistent with improved population health.
These findings indicate that city-wide clean air interventions may not only improve environmental conditions but also reduce pressure on health services, highlighting the wider benefits of upstream, prevention-focused policies.
