My right hon. Friend is absolutely right. I paid tribute to him earlier for making the point that this is not just about our atmosphere, but about our watercourses, our land use and our entire ecosystem. We must focus on the opportunities. When many people hear that we have 12 years to save the planet—that is a terrifying thought—they think, “What is the point? We cannot possibly change anything, because there is so much CO2 and we will never get rid of it.” The point is that we can change, and we have changed. We have done so in a way that has not impoverished people or interfered with our energy security. Energy bills have actually gone down, because energy efficiency in the home has increased. These are myths that we must bust, and we must take people with us as we make the changes.
