There are three big areas. The two areas we can probably influence the most are housing or built stock - in terms retrofitting and avoiding the loss of energy in order to make buildings more energy-efficient - and public transport. Some of those projects are very big. The ones that will bring a real return are those such as the DART underground, where we could borrow for a long-term purpose in the same way that led to the construction of the London Underground in Victorian times. I am only talking about the capital side here. It strikes me that we are paying off promissory notes when we could invest to save by at least heading towards the 2030 targets by taking an initiative now. I cannot understand why this is not seen as prudent. I am probably straying into policy.
