I am afraid I just do not have any time. I will come back to the hon. Gentleman at the end if I do.
I want to respond to the hon. Member for Hornsey and Wood Green (Catherine West), who rightly highlighted the importance of local authorities for cycling, walking and tree planting. I agree with her about that. She asked about the replacement strategy for the emissions trading system. I think she is aware that we have framed two alternatives. The first is a UK ETS, and the second is a carbon emissions tax. We are open to a negotiated agreement, but we have the resources, through either of those options, to implement a scheme that addresses the issues that she is concerned about.
Finally, the hon. Member for Cardiff North (Anna McMorrin) called for leadership not rhetoric. I wonder whether she was referring to the Welsh Government, whose tree planting plans have been disastrous. They seem to be way behind, according to their own tree planting estimates.
The hon. Lady specifically picked out the Swansea Bay tidal lagoon. As my right hon. Friend the Member for South Northamptonshire said, that project would not provide value for money. It would be a terrible waste of public money. That money could be spent much better.
