I'm pleased that you've mentioned the budgetary process, because that's my next destination, and I wanted to ask about the broader budget of the Government and your role as Minister for finance. As one who's been part of scrutinising Government budgets quite closely over recent years, one criticism that's come up relatively regularly is that it's difficult to read across from Government expenditure to measurable outcomes in terms of carbon reduction. Now, how can you look at a budget line on a spreadsheet and be confident that that expenditure is having the impact that you want it to have? It's possible to look at specific projects, that's easily done, but, in order to measure the success of the Welsh Government in driving the broader change that we want to see across government and the public sector, we need to understand how every penny contributes to that aim of net zero. So, with a view to the budget you're working on now, which will be published in a little over a month, how will you ensure transparency and, in light of that, accountability for you as a Government around that particular issue? And also, do you agree that the next budget needs to be the most climate and nature friendly in the history of devolution?
