Question to the HM Treasury:

To ask the Chancellor of the Exchequer, with reference to the Office for Budget Responsibility's report entitled Fiscal risks and sustainability – July 2025, published on 8 July 2025, whether she has asked the OBR to include in its next publication updated estimates of the potential impact of extreme weather related to climate change on trends in the level of economic growth over the next 10 years.

The Office for Budget Responsibility (OBR) is the Government's official independent forecaster responsible for assessing the UK economic and fiscal outlook.

The Office for Budget Responsibility (OBR) is required to prepare an analysis of the sustainability of the public finances annually, known as a Fiscal Risks and Sustainability Report (FRS), as set out in the Budget Responsibility and National Audit Act (BRNAA) 2011. The content of the FRS is determined independently by the OBR.

In its July 2025 FRS included an assessment of the fiscal risks linked to climate change.
