I understand that. The hon. Gentleman will recall that I posed a number of questions in Committee: could the green investment bank invest in forests or in the supply chain for the automotive industry to ensure that we have low-carbon engines? There was a whole range of different debates in Committee, which I thought were useful. As I said, there is a balance to be struck, and that is what new clause 22 is about. Is the aim to achieve what we all want to achieve—igniting, for want of a better term, the green economy—or is the provision too prescriptive? There is a balance between being too broad and too narrow.
