It is a great pleasure to follow the right hon. Member for Doncaster North (Edward Miliband), my right hon. Friend the Member for Hitchin and Harpenden (Mr Lilley) and other colleagues who have spoken today. I do not think any more memorable phrase will come into the debate than the “50 shades of green” used by my right hon. Friend. As so often in this area of debate, people dispute the numbers, as he did with his initial “ 40 shades” effort.
The thread of agreement among everyone who has spoken so far, including my hon. Friend the Member for Selby and Ainsty (Nigel Adams), my right hon. Friend and others, is that if we are setting out to fulfil the requirements of the Climate Change Act, we must do so in the lowest-cost way. My right hon. Friend was right to point out that, given the burden sharing throughout Europe, there is an issue about our taking further steps. Would that simply provide greater slack elsewhere? People may or may not share his scepticism about the whole arena, but none of us would want our making progress to mean that someone else slacks as a result. Therefore, having a joined-up approach is a sensible part of delivering what we all want and doing so at the lowest possible cost, and that is worthy of further investigation.
Where I do not think my right hon. Friend is right is in suggesting that this is purely an exercise in sadomasochism. After all, the Committee on Climate Change’s brief is to fulfil that which was passed in this House, albeit without his support: an 80% reduction in emissions by 2050. If we read the Committee’s fifth carbon report, which was recently published, we see that its whole premise is to try to work out a pathway to get us there at the lowest possible cost. That is one reason why I welcome the reset of the policy by the new Government and our new Ministers. They are not stepping away from the Climate Change Act, although some of my hon. Friends might wish that they were. On the contrary, they are saying that they want to look at how best to make sure we have a policy framework that incentivises activity to meet the outcomes that we all want.
I know from discussions with the Minister of State, Department of Energy and Climate Change, my hon. Friend the Member for South Northamptonshire (Andrea Leadsom), who is nodding in my direction, that one renewables issue we face—this picks up on the point made by my hon. Friend the Member for Selby and Ainsty—is
dealing with intermittency. One way of dealing with that is to develop storage. Have we had sufficient investment and created a framework that has incentivised enough focus on storage while we were also incentivising investment in things such as wind? The answer has to be no. We must therefore try to ensure that we get a framework that captures all the elements that we need in order to create a rational response, so that even if my right hon. Friend the Member for Hitchin and Harpenden does not entirely agree, he can see a more rational thread running through the policy in order that we can deliver.
The Secretary of State played a leading role in the negotiations in Paris, and Britain was at the table, helping to create a more ambitious deal.
