Carbon Budget 6

Baroness Jones of Moulsecoomb Excerpts

Tuesday 3rd March 2026 Lords Chamber

Asked by

[Baroness Jones of Moulsecoomb]

To ask His Majesty’s Government what assessment they have made of whether their policies and plans will deliver Carbon Budget 6.

[The Minister of State, Department for Energy Security and Net Zero (Lord Whitehead) (Lab)]

Carbon budget 6, which was set out in 2021 and is current from 2033 to 2037, was subject to several legal challenges. It is now in the hands of the present Government. The Secretary of State carried out a full and rigorous assessment of the package, policies and proposals prior to publishing the recent Carbon budget and growth delivery plan and concluded that they will enable carbon budget 6 to be met. He will continue to monitor policy delivery and keep the package under review.

[Baroness Jones of Moulsecoomb (GP)]

I thank the noble Lord for the Answer. You can imagine this is something that concerns me, because the previous Government lost two court cases about this as they were not going to achieve what they were aiming for. We have just had carbon budget 7. I am quite curious about whether this Government have really done the right risk assessments. The previous national security assessment said that nature damage will cost 12% of GDP by 2030 relative to what could have been achieved. If Labour are interested in GDP, it really ought to sort itself out on the issue of the environment.

[Lord Whitehead (Lab)]

We do not have the announcement of carbon budget 7 until the summer. The noble Baroness might care to think about what the process of looking again at carbon budget 6 was after those legal judgments. Indeed, the Government have taken a much more robust approach to developing the plan, which has allowed us to make a much clearer and more rational assessment of the savings that will enable carbon budgets to be met and to quantify them fully.

We have also quantified a number of real-world trends that are rather important today, and which are shaping our society and economy. That means our assessment reflects how we would expect the world to change as we accelerate towards net zero. None of these things were done when the previous Administration set out carbon budget 6—indeed, they were part of the legal challenge to those budgets. That is the reason why we consider that carbon budget 6 can be met, in addition to which a number of new policies and directions have come forward since this new Government took office.
