Do they all support us number 15

Two more days on the march and two more Labour MPs; Don Touhig and Julie Morgan.

Whilst in his speech to us Don said "I congratulate you on your efforts", when we questioned him, he thought an 80 per cent cut in emissions is "not achievable". On aviation Don was more positive, saying he "probably supported" the need for aviation to be included within the bill. He'd been lobbied on this already by Nia Griffith, Labour MP for Llanelli, who was on a committee of MPs who argued that the government has to include aviation.

Julie Morgan also said: "I can't see any reason why aviation should not be included." Again, she was less supportive on 80 per cent, thinking it was too ambitious.

Of course cuts of more than 80 per cent are ambitious. But it's not a choice we have to make. The latest science says stopping the worst effects of climate change requires more than an 80 per cent cut by 2050, so that's what we have to do.
