I've set an exam, don't worry.

This includes some elements of housing policy and we will be producing a further document specifically on housing in the autumn. But one area that we did look at in that strategy was green roofing. There are housing developments now throughout England—one example being in Barking in London—where developers are exploring the use of green roofs on housing because of the positive impact they have on thermal insulation, stormwater attenuation, improved air quality, improved water quality, creating habitats for pollinators and improving one's sense of well-being and the number of green spaces around us. I think that the Welsh Government's innovative housing programme could be an obvious way of exploring this type of innovation in Wales, and I do hope that we will see some pilots coming forward now in terms of green roofing, because some UK cities now clearly see this as a very good way of developing effective housing in the twenty-first century.
