My noble friend makes an extremely good point. As I said earlier, if we are going to move forward in the most efficient and effective way, we will have to take the public with us, because they will have to make big changes and, in many circumstances, choose to make those changes—the more information people have, the more the Government can support the changes that need to be made, but it must be done in a way that demonstrates the real science behind it. Too much science around climate change is not proven, so it is really important that we have proper scientific evidence and advice when we are talking to people.
