Climate Change Bill [HL]

My Lords, I wonder whether the noble Lord, Lord Taylor, in responding, could clarify two or three queries that I have about the meaning of his amendment. First, are these indicative targets, or targets in the meaning of the rest of the Bill as it stands? Secondly, does the annual target apply for 15 years ahead? It refers to five-year budget periods and there are three five-year budget periods always in play. Is he asking for 15 years to be published, but for the rolling target to apply only for the next six of those years? Thirdly, what are the means at the disposal of the Government of the day to fine- tune on this annual basis? Taking into account the point made by the noble Lord, Lord Turnbull, the implication that I remarked on in Committee of having targets in the meaning of the Bill is that there are policies that can address those. If we are to go down the annual target route, and for that to be in some sense meaningful in its impact on policy, the Government of the day and the committee advising them must have some levers and tools by which they can respond on an annual basis, as opposed to setting a clear trajectory and a clear strategy with clear policies aimed at achieving that. What are the corresponding annual policies that could fine-tune in that way?
