I thank my hon. Friend for his passionate and well-informed plea. I am well aware of his work with the industry and pay tribute to it. He makes a sensible point. I was just about to talk about how the RTFO certificates work and are tradable. I acknowledge that the demand for and the prices of those certificates will fluctuate for a range of reasons and it is important to understand that that will happen. That might be partly behind one of my hon. Friend’s comments.
