My hon. Friend is absolutely right. A lot of innovative schemes have been set up across the country. I went to see one in Redditch just a few weeks ago in which people are looking at different ways of constructing homes. We have to recognise that the house-building process must change fundamentally: we must change the way in which we build, heat and power our homes if we are to meet the challenge of climate change. I agree that there is a lot more that local authorities can do to support that process.
