Question to the HM Treasury:

To ask the Chancellor of the Exchequer, what estimate she has made of the total public expenditure committed to achieving net zero by 2050, including projected liabilities, broken down by year and department.

The government has allocated £65bn in capital spending to clean energy, climate and nature including nuclear across 2025-26 to 2029-30. This is an average of £16bn a year, mainly across the Department for Energy Security and Net Zero, Department for Transport, and the Department for Environment, Food & Rural Affairs.
