Question to the HM Treasury:

To ask the Chancellor of the Exchequer, what assessment she has made of the data-gathering requirements needed to support future green bond issuances.

In 2024-25, the government raised £10.0 billion through green gilts and green savings bonds. The government plans to issue a total of £10.0 billion of green finance in 2025-26, subject to demand and market conditions. The amount of Green Financing to be issued in each financial year will be announced by HM Treasury as part of the annual government financing remit.

The Green Financing Framework, published in 2021 and updated in 2025, explains how proceeds from green gilts and NS&I’s retail Green Savings Bonds will finance public expenditures that demonstrate a direct and positive environmental impact.

The Framework includes guidelines on the types of expenditures that can be included in the Programme and commits the government to annual allocation reporting. Eligible expenditures are drawn from departments’ confirmed Spending Review settlements and assessed on the basis of their contribution to the government’s climate and environmental objectives. Details of the allocation of expenditure are normally published each year in the Green Financing Allocation Report, most recently published in October2024.
