Making a positive impact on air quality
Air quality is recognised as a significant public health issue, with transport a major contributor to emissions. Overall rail emissions may be relatively minor, but these can be significant at a local level. Nationally, the contribution of rail to air pollution is relatively small when compared to other modes but may be significant at a local level.
The rail industry is working to reduce its adverse impact on air quality. Guidance and goals will be set out in the Sustainable Rail Blueprint to help industry collaborate and improve air quality.
Here we provide information to help you monitor, model and mitigate emissions and ensure efforts are targeted effectively.
