Climate Change

Debate between Olivia Blake and Lee Anderson

Wednesday 24th June 2026 Commons Chamber

[Olivia Blake]

I wonder whether the hon. Member will vote against this measure. That would tell her constituents very clearly her view on this matter.

Back in 2008, under a Labour Government, the UK became the first country to introduce a comprehensive climate framework through the Climate Change Act, which set out the legally binding five-year carbon budgets that we have been reviewing and looking at. As has been said, with carbon budget 6 we did not get the opportunity for scrutiny that we should have got. That legislation was groundbreaking and ensured that Governments can be held to account for delivering long-term climate action. I thank the Minister for her efforts to bring that about.

Nearly two decades later, we can see the impact of that foresight. The UK has successfully halved its territorial greenhouse gas emissions compared with 1990 levels, as we have heard, with much of that progress driven by decarbonisation of the energy system. That is a significant national achievement that we should all be proud of, and it is evidence that ambitious climate policy can deliver real results. It is therefore fitting that it once again falls to a Labour Government to confront one of the defining challenges of our times.

The seventh carbon budget commits the UK to reducing emissions by 87% by 2040 compared with 1990 levels. If achieved, that will mark substantial progress towards our legally binding commitment to reach net zero by 2050. However, at present the UK is built for a climate that no longer exists. The economic impacts are staggering, costing the UK economy around £60 billion a year—about 2% of GDP and rising—through things such as flood damage, loss of crops and other forms of weather damage.

We should also be mindful of the growing environmental footprint of our digital infrastructure. As data centres expand across the UK to meet rising demand, their substantial energy consumption underlines why decarbonising our power system is not simply an environmental imperative, but an economic one. That would provide more opportunities in that space.

I welcome this budget. As we know, climate action is about more than meeting targets; it is about building a country where children are not exposed to toxic air, and where we have warmer, well-insulated homes, lower energy bills and greater energy security. It is about ensuring that future generations inherit a safer and more sustainable world.

However, support for the Government’s ambition should not mean complacency about the scale of the challenge ahead. We face many interconnected crises, such as the climate crisis, the cost of living crisis and the nature emergency. Families continue to face high energy costs, while communities increasingly experience the impacts of flooding and extreme weather. The answer is not to slow down the transition and make things worse, but to accelerate it in a way that delivers tangible benefits for our communities.

[Lee Anderson (Ashfield) (Reform)]

The hon. Lady is making a very passionate speech. She seems to be an expert on this subject, so could she advise the House by how much it would reduce the Earth’s temperature if this country became net zero right this minute?

[Olivia Blake]

Obviously we cannot do this on our own, which is why the global leadership we show in this space is very important. We have international agreements that aim for 1.5°, but as we have heard, we are heading more towards 2°, 3° or 4°. Moving away from our own commitments will leave us further behind; globally, emissions must peak urgently and then decline rapidly. The UK’s influence has always exceeded its size—we have always punched above our weight, and I am proud of that—and our credibility depends on continuing to lead by example. That is why we must see this carbon budget not as a ceiling but as a floor.

The budget broadly reflects the direction of current Government policy, but it must be accompanied by the bold action necessary to deliver it. The Environmental Audit Committee, of which I am a member, has been clear that the UK’s climate credibility depends on not simply setting ambitious goals, but demonstrating how those goals can be achieved. The Committee has called on the Government to set out clearly how this budget will be met and how the policies that underpin it will be delivered, reducing emissions in the way it sets out to do. However, today marks an important first step, and I am proud to see something ambitious in front of us. If we are serious about meeting this budget, we must match ambition with action—accelerating clean energy, not abandoning it; upgrading our housing stock from what has historically been some of the poorest in Europe; supporting the industries of the future, which will provide jobs; and ensuring that communities across this country share in the benefits of this transition, leaving no community behind.

The prize is enormous—we should not listen to the naysayers. Lower exposure to volatile energy prices, greater energy independence, more skilled jobs, better security, cleaner communities and a stronger economy are within our grasp. Climate action is not a burden to be managed; it is a necessary opportunity to be seized. As such, I support the order that is before the House, but I also urge Ministers to see it as the beginning of the task before us, not the end. Ignore the naysayers—the science demands urgency, our constituents expect leadership, and the opportunity is before us. Demand that we are bold, and let us meet this moment with the ambition it deserves.
