Climate Change Bill [HL]

My Lords, before the Minister responds to my noble friend, will he clarify his initial contribution? I understand that the Government clearly accept that they will come forward with something every 30 months. The Minster then spoke of other departments feeding into the system, headed up by the Cabinet review every five years. I do not quite understand how you could get those two views together, when one is on a 30-month basis and the other, if I understand the Minister correctly, is on a five-year rotation. I would be glad if the Minister could clarify that.
