It's not for people who understand the reality of climate change to defend that position. That ship has sailed. The question is really for those who don't believe in the facts of climate change. Why don't they?
It's not for me to defend that, but I will say that the signal it sends out to international markets that the second-biggest political party in our House of Commons does not believe in the reality of climate change does nothing for the investment community. It does nothing for increased investment in this country, absolutely nothing.
