Question to the Department of Health and Social Care:

To ask the Secretary of State for Health and Social Care, what assessment has been made on trends of indoor air pollution.

The Air Quality Expert Group state that there is a challenge of establishing overall trends in indoor air pollution due to limited monitoring and heterogeneity of indoor environments.

The UK Health Security Agency (UKHSA) is actively addressing this evidence gap through its involvement in two research hubs, headed by UK Research and Innovation and the Medical Research Council, the Child and Adolescent Health Impacts of Learning Indoor Environments under Net Zero Hub, also known as the CHILI, Hub, and the Indoor HABItability during the Transition to Net Zero Housing Hub, also known as the INHABIT, Hub. In addition, the UKHSA contributes to the National Institute for Health and Care Research’s Health Protection Research Unit on Climate Change and Health Security Theme on Healthy Indoor Environments. Collectively these projects aim to strengthen the evidence base on the impact of climate change policies on indoor exposure to air pollution and will include monitoring of indoor environments.
