Climate Change Bill [Lords]

My hon. Friend makes an important point, as he always does on these and other matters. How one reaches the target is more important than the target itself. I do not diminish the importance of the target as a framework for action, but it is the interim budgets that set us on that track. The work of the independent Climate Change Committee will give advice not just on the interim five-year budgets, but on policies to achieve them, and we must take decisions in light of that. Plan B is a combination of the international situation—including what we do if there is not an international agreement at Copenhagen—the interim budgets and the potential international agreement to mid-term targets as well as long-term goals.
