Embodied Carbon: Buildings

Nusrat Ghani Excerpts

Monday 13th July 2026 Commons Chamber

[Dr Chowns]

Absolutely. As we have discussed, we should reduce, reuse and recycle; let us make sure that every part of a building is reused in the best way possible. Demolition should be the absolute last resort, so it sounds like the hon. Gentleman’s planning authority is taking the right direction.

Last year, I attended an embodied carbon industry summit, which was held just over the road from this House. At the summit, a simple question was asked of attendees: without Government intervention, will local embodied carbon rules become more consistent or more divergent? The response was absolutely resounding: the rules will continue to diverge without Government leadership. It is clear that national regulation on embodied carbon will reduce complexity for the construction industry, not increase it. It will replace fragmentation with consistency, create a national carbon dataset, and provide certainty for industry, while delivering meaningful carbon reductions. Surely that is exactly the kind of planning reform that this Government should want to achieve.

As the Environmental Audit Committee highlighted in its 2022 report, “Building to net zero: costing carbon in construction”, regulating embodied carbon would be

“the single most significant policy the Government could introduce”

if they wish to tackle the reuse of buildings, the development of low-carbon materials and a reduction in these emissions. Why are we still waiting?

The encouraging news is that the construction sector is not waiting for Government. For more than four years, more than 250 organisations from across the built environment sector have supported a campaign called “Part Z”, named after the various other parts of the building regulations. They have been calling for national embodied carbon regulation. Those companies are not asking the Government to invent something entirely new. Indeed, the same experts who developed “Part Z” have now produced the UK net zero carbon buildings standard, a ready-made framework that provides a practical route to compliance. It builds on the Royal Institution of Chartered Surveyors’ whole-life carbon assessment methodology, one of the most developed embodied carbon methodologies in the world. These documents could form the basis of future regulatory reporting requirements and, in time, a new approved document. The Government do not need to start from scratch; the construction industry has already done much of the hard work.

Indeed, members of this Government used to be in support of such action. When a private Member’s Bill on embodied carbon was debated in 2022, Jonathan Reynolds, now the Government’s Chief Whip, and previously the Secretary of State for Business and Trade, said “We support it”—

[Madam Deputy Speaker (Ms Nusrat Ghani)]

Order. We do not talk about colleagues by their first and second names. We mention their constituencies, and if we are mentioning them, we give them the courtesy of letting them know that we will do so. I say that for future reference, to make sure that it does not happen again.

[Dr Chowns]

I am so sorry, Madam Deputy Speaker. I stand entirely corrected. The aforementioned right hon. Gentleman said:

“We support it. I agree with his proposition that industry would welcome further regulation in this area”.—[Official Report, 25 November 2022; Vol. 723, c. 620.]

He was right then, and that statement is right now, because this is not regulation that industry fears; it is regulation that the construction sector is asking for. Industry is calling for this, because it provides a level playing field, creates local green jobs and boosts investment in lower-carbon materials. Good regulation rewards innovation, provides certainty for investment and gives British businesses the confidence to lead.

The rest of the world is moving ahead in this area. The Netherlands has regulated embodied carbon for more than a decade. The EU requires reporting from 2028 and will have limits from 2030. Türkiye is requiring reporting from 2027. Several US states mandate reporting today. Meanwhile, Britain, despite having world-leading engineers, researchers and designers, risks falling behind. This is not simply an environmental issue; this is an industrial strategy issue. It is a planning reform issue and a housing issue. It is about whether Britain intends to lead or follow.

Today, I ask the Minister for one thing above all else: national leadership. I ask for a clear pathway towards national regulation to measure and reduce embodied carbon, aligned with the direction already being taken by many of our international partners and by many in the construction industry. I ask that embodied carbon is finally recognised within national planning policy, replacing today’s fragmented patchwork with one coherent national approach. I ask the Government to consider using the UK net zero carbon buildings standard as the route to fast-tracking the compliance requirements, finally giving industry the certainty it has been requesting for years. When will the Government finally release their long-delayed circular economy growth plan, which could deal with embodied carbon at its core?

Climate change is not hanging around, as we can see around us all the time, and embodied carbon is only making things worse. We can and must change that. We have the expertise, the methodology and the support from industry. Local authorities are crying out for consistency, and the standards have already been written—the only thing missing is national leadership. I call on the Minister to provide it.
