For what reasons he plans to introduce the future homes standard in 2025.

Our future homes standard reforms propose an ambitious uplift in the energy efficiency of new homes. The homes will have at least 75% lower emissions than current standards. That is real action toward a cleaner and greener built environment. Furthermore, ahead of 2025, we have consulted on a meaningful interim increase in the requirements of part L of the building regulations, which will act as a stepping stone to a full uplift.

If I cannot persuade the Minister to be more ambitious in his deadline, perhaps I could encourage him to use the time to be more ambitious in his target. Instead of a target of reducing carbon emissions by 75%, will the Government set a target of net zero carbon for new builds?

I am obliged to the hon. Lady. She seems to have forgotten the ambition of this Government, which has already been stated. We were the first Government in the world to legislate for net zero. She seems to have forgotten that just a few days ago, we introduced the green homes grant; 600,000 homes will benefit from that grant. She seems to have forgotten the work we have done to drive down poor energy performance certificate standards; now only 5% of homes are in the G category. We will certainly be ambitious. We will continue to work hard to build green homes for our country, and I am sure that when it comes to it and the hon. Lady stops talking, she will start to walk with us.
