Contribution
I am grateful for that question. I cannot make that commitment to the hon. Member today. I hope the assurance I have given has demonstrated that there is a pretty clear landing zone for local authorities, but it must work within national standards. I also make the point, as others have, that the future homes standard consultation has come to a close, and we are consulting on the national planning policy framework. So there are some moving plates in the current setting of standards and we must be mindful of them.
The second point that the hon. Member for North Herefordshire made was about embodied carbon. As we make progress on solar panels, heat pumps and all the other ways to reduce operational carbon emissions, we will see emissions fall in buildings, and therefore embodied carbon will make up proportionally more of a building’s whole-life carbon emissions. We are committed to understanding the scale of the challenge as part of our broader efforts to decarbonise the construction sector. It is vital that we encourage industry to reduce embodied carbon by choosing lower-carbon, but still high-quality, materials. That requires a fundamental shift in design and construction, and that is why we are pushing so hard to encourage the adoption of more efficient design practices that minimise waste, which the hon. Member for Guildford mentioned, and make better use of low-carbon materials such as timber. There are some very exciting new technologies in that space. Where it is safe to do so, higher-carbon materials will be gradually replaced along the way.
The third point that the hon. Member for North Herefordshire made was about solar panels, and this is where we may slightly differ. The Government’s judgment is that we should set targets with regard to performance—what is the energy performance of the new home? Solar panels may well be part of that, but for some buildings they will not be suitable. As a result, if the choice is primarily solar, we miss out on a whole array of innovations that can help those homes reduce their carbon footprint, and there is a risk to cost-effectiveness. As I say, we are goal-oriented, rather than method-oriented.
The hon. Lady mentioned biodiversity net gain. We should recognise and build on the work that the previous Government did in this space. We see this—I think they did too—as a real opportunity as we address our urgent housing needs. We owe it to future generations to ensure that development leaves the natural environment in a measurably better state than it was. That is now mandatory for new applications for developments: all new developments, with limited exceptions, will be required to deliver at least 10% measurable net gain. The hon. Lady spoke about 1.5 million bird and bat boxes, but I would not want to be quite as prescriptive as that. We expect to see net gain, whether through the creation or enhancement of habitats on or off site, or through the purchase of registered biodiversity units on the new open market. We are working very hard with the sector to make sure that it realises those brilliant opportunities.
Let me turn to the hon. Lady’s fifth point, which was on resilience and water. As the Minister for local resilience, among a number of things, that was of particular interest to me. Immediately prior to the debate, I took part in the inaugural meeting of the flood resilience taskforce, which seeks to bring together partners to reduce the number and the impact of floods. I know from having dealt with constituents that having your house flooded is one of the very worst things that can happen to you, short of losing your life or losing a loved one, because you live with the impact of it for so long.
We have a responsibility to make sure that development does not contribute to greater flooding, and the planning system is at the heart of that. We must ensure that development is in areas at the lowest risk of flooding and that it uses sustainable drainage systems to mimic natural systems and to slow the flow of surface waters. The current consultation on proposed reforms to the NPPF is seeking views, and we would be interested to hear from colleagues on that. It is a big opportunity.
The hon. Lady also mentioned water. Safeguarding the water supply is crucial to meeting our climate obligations. As we undertake consultations, we are actively looking at options relating to water efficiency in planning and building regulations. We are developing guidance on water-positive and net zero water developments and on how to integrate water efficiency into energy efficiency and retrofit programmes.
To make a quick point about the NPPF, the planning system is critical to delivering sustainable development that aligns with climate goals. Our NPPF reform marks an important milestone in that journey. Our consultation is seeking views on how planning policy can better support the industry to adapt. We hope to get that feedback, and we will consider any and all contributions.
The Opposition spokesperson, the hon. Member for Ruislip, Northwood and Pinner, made a point about product standards to me for the fourth time in the past 24 hours. I can give him clarity that nothing in that statement from 2 September is about the reduction of standards—far from it. I reiterate the commitment I made yesterday that the Minister for building safety, my hon. Friend the Member for Bethnal Green and Stepney (Rushanara Ali), will write to him with further detail.
While building the homes this country needs to tackle the housing crisis, we will ensure that our climate change commitments are met. We will set high energy-efficiency standards, ensure water efficiency, secure biodiversity net gain and deliver flood-resilient developments as we lay the foundations of a sustainable future. We will ensure that everyone has access to a decent, warm and affordable home. That will be one of the standards by which this Parliament is measured and one of the ways in which our adherence to the manifesto on which we were elected is measured, too. We are actively doing that work. I am grateful to colleagues who want us to go further and faster, and that pressure is welcome. I look forward to working with all colleagues as we go along that journey.
