Thanks very much, Russell, and I'm glad to see that you agree with our net-zero ambition. I think that one of the benefits of today is that, actually, we are raising public awareness, we are telling people that this is something that has to happen in all sectors of our policy areas. Although in relation to the NHS, it may not be the thing that people think of as the first most important issue for them, it is clearly something that we need to take seriously in every aspect of our lives, and the NHS will be central to that as well. And the fact is that the NHS emits about 1 million tonnes of carbon dioxide—certainly, in 2018-19 that was the case—so we've got a long journey to go on. You talk about the existing stock, and you're quite right—there are some old buildings in the NHS, and there are some new buildings, and, of course any new building will have to be procured and will have to comply with our net-zero ambitions. But, by 2026, we've made it clear in our decarbonisation strategic delivery plan that every building between 2026 and 2030 will have undergone an energy-efficient upgrade, and low-carbon heating will be utilised and renewable energy will be generated on site. So, we're absolutely clear about where we're heading on this.

Like you, I represent a very rural area. I'm very aware of the sensitivities around rurality and access to public health. But what I've found, actually, is that it's been quite transformative, the whole experience of the pandemic, and that we've all learnt to use technology in a way that we weren't aware that we could do before, and it has been embraced by the NHS. It's been wonderful to speak to patients who previously had to trek miles and miles and miles to go and see a specialist, and now they can have a remote consultation. So, I think that's been a huge benefit, not just in terms of climate change, but also for the patients themselves, of course. But of course there will be times when people have to physically go and meet the specialist, particularly if there's an operation to be had. So, this is all about balance, and we've got to get the balance right, but certainly when it comes to rural-proofing, I think you're absolutely right. We need to think about this at the beginning of the process. One of the things I've been talking about today is the issue about the kind of support that is given by so many people who voluntarily take patients to hospital and the need for us to appreciate them a bit more. So, that's something that is very much on my agenda as well.
