My Lords, I support the amendment from the noble Baroness, Lady Brown, because I know from my experience as chairman of the Climate Change Committee why it works. It works because there are statutory targets to be met within reasonable times. If the target date is 2050, no Minister presently serving will have to be responsible for it. Indeed, I remind my noble friend that when a former Labour Party Administration announced a date for net-zero houses which was some 10 years later, there was ribaldry on the Conservative Benches on the basis that that would mean that they would not have to do anything during their period of office.
I am afraid I am long enough in the tooth to recognise that the Climate Change Act ensured that no Government could put off the actions they had to take until a more convenient time arose. The brilliance of the Act was to bring together two very different timescales. One is the democratic timescale of four or five years for the renewal of mandate and the other is the continuing timescale of fighting climate change. A democratic society has somehow to bring those two together. The cleverness of it was that by ensuring that Parliament agreed on the interim budgets and therefore they were democratically voted on, the Climate Change Committee was then able to hold the Government to them. They could not be changed without their agreement. That brought these two things in line.
What surprises me about my noble friend’s—and he is a noble friend—reply during the previous debate was his suggestion that somehow everything that is true about the Climate Change Act does not count in the Environment Bill. He does not believe that because he is a great supporter of the Climate Change Act. It is just not possible to hold those two views. I fear that this is the result of some apparatchik somewhere who does not want anybody to be held to anything. All of us should recognise how dangerous that is from the news today. Despite everything that has been said at this Dispatch Box and a similar Dispatch Box in the other House, the Government have bent over to the Australian Government and removed from the agreement the commitment to meeting the climate change figures and temperatures in the Paris Agreement.
If that is so, how can we possibly accept merely the assurances? We have to have it in the Act—we have to have it clearly there, not because we have any doubt that this Minister, this Front Bench, would do what they say they are going to do, but because we have lived long enough to know that if it is not in the Act, in the end it does not get done.
