The government's green financing programme has raised a total of £43.4bn since it was launched in 2021.
The Treasury's full Budget report sets out the latest figures of the programme under which green gilts and green savings bonds are issued.
The gilts and bond are issued by NS&I, the state-owned savings bank. The report sets out NS&I's net financing target for the year remains at £9bn.
It added: "The government’s plans to raise £10bn via issuance of green gilts in 2024-25, subject to demand and market conditions, remain unchanged."
Total green gilt proceeds in the financial year to-date stand at £5.7bn. While the Treasury said green savings bond, brought on sale in October 2021 has "allowed UK savers to support the government’s green spending initiatives".
As of October 2024, NS&I forecast to have raised a £1.8bn through green bonds since its launch three years ago.
The report added: "NS&I expect additional inflows for 2024-25 to be below the upper limit of £500mn, subject to market conditions."
The government Debt Management Office's net financing requirement for 2024-25 was revised up by £12.4bn in April to £277.7bn.
In this week's Budget it was revised up a further £22.2bn to £299.9bn.
The Treasury said this will be delivered through an increase in gross gilt issuance this year of £19.2bn and a £3bn increase in financing raised through net issuance of Treasury bills for debt management purposes.
