Thank you for your answer. It's three years now since France legislated that all new buildings in commercial zones should have green roofs, and that means either partially covered by plants, which helps insulate the building and helps retain rainwater and also promotes biodiversity, or, of course, solar panels. I'm wondering what your Government's ambitions are in that respect and whether you think, given that you say you have stretching targets, they could stretch as far as maybe trying to replicate this, particularly maybe in relation to new public buildings in Wales.
