I start by putting on record my sincere condolences to Wales for their loss today, and I wish England the best of luck for their match against the USA later. We will all be very much cheering them on.

I sincerely thank my hon. Friend the Member for Broadland (Jerome Mayhew) for introducing the Bill, and for his incredible efforts to raise awareness of embedded carbon in construction. He is a fantastic champion for all things environmental, and has been right from the point of his election; protecting the local environment was part of his election plan, and he has been a great champion for the measures that we are discussing through his work on the Environmental Audit Committee.

Given the schedule that we are on today, our time would be best used by allowing the Minister to reply in full, but I congratulate the hon. Member for Broadland (Jerome Mayhew) on his Bill. We support it. I agree with his proposition that industry would welcome further regulation in this area, and I wish him well in his endeavours in this field.

I completely echo the shadow Minister’s sentiments.

As hon. Members will know, the Government considered closely the Environmental Audit Committee’s report, “Building to net zero: costing carbon in construction”, and its recommendations. In our response, we were pleased to set out details of our work in this area, including our plan to consult next year on our approach to measuring and reducing embodied carbon. As we made clear in that response, reducing embodied carbon in construction is critical to meeting our net zero target. I think that all of us across the House can agree on that, but we disagree with my hon. Friend the Member for Broadland about the exact mechanisms and timings for achieving that. That is why, I am sorry to say, the Government cannot support the Bill today. It is not because we disagree with the Bill’s aims, but because ambitious work is already well under way in this area. Passing the Bill ahead of that work would risk adverse effects on our housing supply, on small and medium-sized enterprises and, given the reach of our construction industry and supply chains, on other sectors of the economy.

That said, although we are not supporting this Bill, I am incredibly grateful for my hon. Friend’s enthusiasm, and for keeping this topic at the forefront of our minds. The Under-Secretary of State for Levelling Up, Housing and Communities, my hon. Friend the Member for North East Derbyshire (Lee Rowley), who is responsible for local government and building safety, and officials in my Department are keen to work collaboratively on this vital agenda with my hon. Friend. I know that the Minister is happy to meet my hon. Friend the Member for Broadland to talk through the detail of his work.

On embodied carbon and the work being undertaken, my hon. Friend has already outlined the process for calculating whole-life carbon, so I will not go into that in too much detail, but we do know that the focus until now has been on reductions in operational carbon. As that process happens and we reduce the amount of operational carbon in construction, embodied carbon emissions will start accounting for more of a building’s whole-life carbon emissions. He is therefore absolutely right that we must act with the construction industry to address the issue now. Equally, we cannot be naive about the scale of the challenge ahead of us.

Reducing embodied carbon is exceptionally difficult across the built environment—not just in buildings—which is why the Government have been planning ahead to tackle those emissions head-on. The industrial decarbonisation strategy and the transport decarbonisation plan, for example, set out how large sectors of the economy will decarbonise, and the England trees action plan looks to increase the production of timber, which can be used to replace higher-carbon materials in construction when safe to do so. As those policies take effect and industries that supply construction decarbonise, we expect that in turn the embodied carbon emissions of buildings will fall.

We recognise that those efforts alone will not be enough. As pointed out by both the Climate Change Committee and the Environmental Audit Committee, our choice of materials and how we design and construct buildings will also need to change dramatically.
