Llywydd, I want us to have the most ambitious, achievable climate change targets that we can put in place. For that, we rely on the climate change commission and their advice. If the context across the United Kingdom changes, if we have a different Government in the United Kingdom pursuing different policies there, such as the green new deal that my party have been talking about this week, then, of course, the advice from the climate change commission will need to be sought again in that new context. And I want us, in Wales, to be as ambitious as we possibly can be, within the limits of those who know the most about the topic and provide us with the most authoritative advice. 

In my decision on the M4, to say it again, I distinguished between the financial costs of the M4 relief road, which I concluded were not sustainable 10 years into austerity, and the environmental matters. And I rehearsed the environmental matters there. And I've read in detail what the inspector's report said about carbon neutrality. And from memory—I'll have to check, and I will write to the Member to tell him if I've remembered it incorrectly—with the series of assumptions that the inspector made, he said that this road would be carbon neutral by 2073. Now, if you think that that's sufficiently ambitious for us, then I certainly don't.
