Question to the Department of Health and Social Care:

To ask His Majesty's Government what steps they are taking to ensure that the proposed WHO Pandemic Preparedness Treaty, due to be considered by the 77th World Health Assembly in May, will include provisions to improve indoor air quality.

The United Kingdom welcomes the Pandemic Accord as an opportunity to strengthen global health security. Improving indoor air quality remains an important issue in public health. However, as the Accord aims to establish a high-level framework for pandemic prevention, preparedness and response, we have pursued action on this specific issue in other multilateral settings.

The UK continues to support international improvements to indoor air pollution through its engagement with the World Health Organization (WHO). For example, the UK Health Security Agency (UKHSA) contributed to WHO projects in 2020 and 2022 to assess combined exposure to multiple chemicals in indoor air in schools. UKHSA continues to work with the International Society on Indoor Air Quality and Climate on the development of an open database on international indoor environmental quality guidelines. The database aims to be actively used by researchers, practitioners, and policymakers across the world.

Moreover, the UK was a strong advocate for action to improve indoor air quality at last year’s United Nations General Assembly. We worked with international partners on this issue during the High-Level Meeting on Universal Health Coverage. The UK was supportive of reference being made to the health impacts of indoor air pollution, which was subsequently adopted in the meeting’s political declaration on 5 October 2023, and is available on the United Nations website in an online-only format.
