I thank my right hon. Friend not just for that question, but for all the work that she has done in this area. She held the brief in ministerial office, but, on leaving that office, she has continued her interest and has worked on a number of policies to help move on this agenda. She is absolutely right: we cannot expect people, including Members of this House, to make those changes to their lifestyle—the kind of car they buy, how they heat their homes and so forth—unless we have the infrastructure in place, and unless we have the innovation and the support for that innovation to bring forward products that people will want to take up. I shall certainly take up that suggestion, and she will know better than I who I should take it up with.
