My Lords, I rise to support Amendments 4 and 19 in the names of the noble Lords, Lord Ravensdale and Lord Browne of Ladyton, the noble Baroness, Lady Chapman of Darlington, and myself. I commend the noble Lord, Lord Ravensdale, in particular for his tireless work on this issue. I too join in the tributes to the noble Lord, Lord Broers, and wish him well in his retirement. I also have some sympathy with the intention behind the Amendment of the noble Baroness, Lady Bennett, which raises very important and wider questions, but I am going to focus on Amendment 4.

As the noble Lord, Lord Ravensdale, has said, a number of Acts of Parliament that have gone through this House have had “have regard” amendments relating to climate change made to them. I was pleased to be a signatory to the cross-party amendment to the Financial Services Bill, which the Government substantially accepted in this regard. This point of consistency is extremely important. However, I would have preferred it if the Government had been willing to accept a stronger amendment on the purpose of the organisation, but I recognise that political pragmatism is wise on occasion.

In Committee, we had a very useful discussion about whether the agency would benefit from the sort of mission and focus that helped the Defence Advanced Research Projects Agency in the United States—mentioned by the noble Lord, Lord Ravensdale—achieve its success. The noble Lord, Lord Lansley, told us that DARPA’s mission had been to not be taken by surprise by new technology and, perhaps by implication, to surprise others with the advanced technology of the United States. That may well have been the mission, but the purpose of the mission was surely what drove DARPA’s success: to maintain the national security of the United States against the threat of Soviet communism. It is that purpose which provided DARPA with its edge, its sense of urgency and an understanding of the stakes of the mission on which it was engaged.

While Soviet communism posed an existential threat to our freedom then, today the threat we face from climate change and ecological destruction is even more acute: an existential threat to life itself. Surely, there can be no more profound purpose to drive our new advanced research agency, no greater focus to inspire research, innovation and the practical application of science, than that of tackling a threat to humanity itself.

Personally, I would have liked that to have been ARIA’s explicit purpose; nonetheless, I am heartened by indications that the Government might be prepared to move on this issue. I am very pleased to support this amendment because I think it would represent important advances to some degree on this issue. I very much commend the noble Lord, Lord Ravensdale, for—hopefully—his persuasive powers in getting the Government to the right place. I will listen carefully to what the Minister has to say, but I still suspect that future generations will look back with a degree of surprise that at this time, and in the knowledge of the climate and ecological threat we face, our advanced research agency was not more clearly harnessed to this, the gravest and most important task at hand.
