To ask the Secretary of State for Health which local authorities in England and Wales have (a) assessed air pollution in their latest Joint Strategic Needs Assessment and (b) prioritised action on air pollution in their latest health and wellbeing strategy.

The Department does not hold this information. Public Health England publishes estimates of the fraction of mortality in English local authority areas and regions attributable to long-term exposure to particulate air pollution arising from human activities. This information is published as one of the indicators in the Department’s Public Health Outcomes Framework. These estimates will inform local health and wellbeing boards’ development of their Joint Strategic Needs Assessments and health and wellbeing strategies.
