Climate Change Bill [HL]

I do not suppose that the Minister needs any further urging to resist the amendment, but I would encourage him to do so, because the science of climate change is difficult and imprecise and is always subject to short-term fixes. Experts are always saying, ““Goodness, the evidence shows that we suddenly have anomalies””, and a three-year database will quite clearly create further uncertainty. I therefore believe that my noble friend is right to say on this occasion that a five-year period is reasonable. It also, incidentally, chimes quite well with international agreements. The Kyoto agreement is on a five-year budget, and so for that matter is the European Union Emissions Trading Scheme, so a five-year period makes perfect sense.
