Thank you very much, and indeed I was pleased to meet with the MP James Davies amongst many others at COP. There was a good Welsh presence at the conference.

He makes mention to some of the world's worst polluters, well of course we are amongst the world's worst polluters. Let us be clear, those of us in the G20 are the countries that have contributed to this problem, and those currently facing the most immediate short-term impacts from climate change, more severely than ours, are those who've contributed the least to climate change. So, there is a moral obligation as well as a self-interested obligation on us to act. But let us be under no illusion about our culpability in the problem as well. It's not simply China or Brazil or India, we as the UK are part of the problem and we need to transition from that, and as we do it, it must be a just transition. Steel production is a really interesting example. Clearly, we will still need steel, even beyond 2050. To produce wind turbines or electric cars, you need steel. We need to find a way of producing steel that has the minimal negative environmental impact.

There is work going on in south Wales, through the south Wales industrial cluster—industry-led, working with the Welsh Government and the UK Government together—to try and find technological solutions to the problems, and to try and reduce the carbon footprint of these heavily polluting but important industries. That is a dilemma for us, and it's not an easy transition, but it is one that we absolutely have to confront.

In terms of carbon capture and storage, I am sceptical of the impact that that can play because, at the moment, it is an unproven technology. There are some trials to show that it can work. It has not been demonstrated to work at scale. The thing that I worry about in the UK Government's net-zero plan is that it relies heavily on the assumption that these technologies will work at scale within 10 years. That has yet to be proven, and I don't think that we should be betting the farm on the fact that technological fixes are going to deliver the carbon reductions that we need to see.
