My Lords, my Amendments 145B and 216 on overheating and climate change are in this group. This is an important group, and we generally support all the amendments that have been put forward. We have just had the warmest summer on record—the warmest since 1884. Summer temperatures were 1.51 degrees above the long-term meteorological average and all five of the hottest summers have been since 2000. A summer as warm as the one we have just had is now 70 times more likely due to climate change. Obviously, continuous exposure to heat is a slow-motion killer and it is bad for our population. Our homes are not built—or fit—for the future, which is here now. Buildings are responsible for over 40% of the energy demand in the UK. Some 80% of the buildings that will be occupied in 2050 have already undergone construction. Therefore, we must do more—all of us—to ensure that the homes we build and plan today are fit for the future. My Amendment 145B asks that, where a spatial development strategy includes provisions relating to housing, it also includes provisions for housing to meet recognised high efficiency and climate resilient standards, including but not limited to Passivhaus standards. This is with a view to reducing energy consumption, improving temperature controls and ventilations, particularly in response to extreme heat and contributing to our regional climate change mitigation and adaption objectives. We have to do more. The Climate Change Committee has also been clear on these points. The UK will not meet its emission targets “without near-complete decarbonisation of the housing stock”. The houses we build are places of shelter. They need to provide long-term security, affordability, to be resilient and to cope in the warming climate. This is about asking simple questions about the houses we are building. Are they fit for the future? Each new home that we build without proper standards leads to higher emissions, higher heating costs and greater vulnerability for those that live within them. Conversely, if we build to high efficiency standards, we can curb our emissions, reduce future retrofitting costs, protect families from the risk of heatwaves and reduce their energy bills. The amendment refers to standards, particularly Passivhaus, but it allows flexibility; it is not restrictive, and it is not telling local authorities what they have to do, but it is for them to have regard to these things. Therefore, it is not prescriptive. We believe that is a good way of doing these things. It can save people money and give them a better quality of life. We think that this is a good amendment. Amendment 216 proposes that every new home built in the country should meet a net-zero carbon building standard and be equipped with solar-powered generation as standard. I thank the noble Baronesses, Lady Young of Old Scone and Lady Jones of Moulsecoomb, and the noble Lord, Lord Grantchester, for adding their names. This not a radical measure; this is a reasoned, practical response, designed to support government policies which are either in development or are being developed but have not fully been put forward. Obviously, it covers exactly the same points. As we know, retrofitting is five times more expensive, which is just too expensive. We do not have the time, and we cannot afford to wait. I acknowledge and thank the Labour Party for the work it is doing in this space. We look forward to the future homes standard and welcome the moves the Government are making on installing rooftop solar. There are various different strands and elements of policy that all need to come together. There is a warm homes plan, the overheating requirement that the Minister has referred to as well, and general building regulatory reforms around zero-carbon buildings. But a lot of these measures are either not here or not strictly laid down in planning law with the certainty that my amendment has. While I welcome the measure the Government are taking, and I know there will be policies published in the autumn, I want to push the Government as to whether, when those policies come forward, they will have the level of certainty to meet the actions we need. My amendment hopes to solidify and support the work that the Government themselves are actively doing, and to strengthen some of those measures. My question to the Government is: if you are not supporting my measures, what certainty can you give us around the weight the measures you will put forward will have in law? I give my support to Amendment 127, so ably spoken to by the noble Lord, Lord Ravensdale, and supported by the noble Lords, Lord Hunt of Kings Heath, Lord Krebs and Lord Grantchester. I will not speak to it for too long, but this is an essential amendment. As the noble Lord said, it puts a golden thread through this stuff. “Have regard to” is good wording. This stuff needs to happen. All too often, these issues are ignored or set aside and do not have the clear weight within planning law that they need to. Therefore, we welcome this amendment. This needs to change and it is a sensible and well-reasoned amendment. I am in favour of Amendment 180, tabled by the noble Baroness, Lady Bennett of Manor Castle, which would introduce a carbon assessment, as required for larger developments. We are no longer blind to one of the most significant drivers of climate emissions. The construction sector is responsible for a quarter of the UK’s carbon footprint and that is set to rise. These emissions remain largely invisible within the planning system, and we need a proper system to take better account of them and to regulate them, so we also support this as a sensible amendment.
