I note with interest that you obviously highlight the fact that we have an obligation to reduce our carbon emissions by 80 per cent by 2050, and you also highlight the importance of the south Wales and north Wales metro, as well as getting all local authorities to deliver on joined up active travel. How do you think we’ll be able to measure the progress on these bits of the programme and what target do you think we should be setting in the interim basis to ensure that, suddenly, in 2040, we don’t realise that we haven’t met our obligations?
