My Lords, I want briefly, having just had a signal on those lines, to offer Green support for all the amendments. I will speak only to Amendment 261 in the name of the noble Lord, Lord Foster of Bath. I commend him on his long work in this area.
I am perhaps a little less charitable to the Government than him about where things are now. Just this afternoon, while we were debating the second group of amendments, the Green Alliance put out a new report, Cutting the Cost of Living with a Green Economy. It has some figures that are interesting and helpful for this debate. It points out that the cuts to energy efficiency subsidies and the scrapping of the zero-carbon homes policy over the past decade saw the installation rate of home insulation and energy measures go from 2.3 million in 2012 to 230,000 in 2013—a rate that has continued since.
This addresses the question that the noble Baroness, Lady Neville-Rolfe, just asked about what we can do and whether it is possible to step up again. We have done this in the past; we can do this in future. The noble Baroness expressed concern about a lack of costing for that. The Green Alliance report points out that, if we followed Amendment 261, through insulating 15.3 million homes, it would save them all £511 a year after the April price cap rise. For the country, that is £7.8 billion a year, mostly in fossil fuel.
Looking again at the costing, the Great Homes Upgrade plan, put together by the New Economics Foundation along with 28 organisations, shows that spending £11.7 billion over this Parliament could raise 7 million homes up to this standard by 2025. As the noble Lord, Lord Foster, said, this is very much a health and safety issue. We have set the standard of zero carbon by 2050. That is a target for the environment; this is a target for people’s health. Surely we can have both health and environment targets that so crucially fit together.
