I welcome my hon. Friend’s mentioning an independent report which shows that we have decarbonised, as a proportion of our economic growth, faster than any other country in not just the G7 but the G20. We continue to work to accelerate our carbon reduction. He is right to focus on heating, which is a major problem for a centralised gas-based heating economy such as ours. Innovation is happening in Keele, Leeds and other areas to see how we might safely introduce hydrogen into the heating system. Of course, we then have to produce hydrogen in a low-carbon emissions form, which is an opportunity to use excess renewable energy, and particularly offshore wind. This is an incredibly innovative time. By the way, if we can help the world migrate to hydrogen boilers and make those boilers in the UK, we can export them and create a competitive advantage as part of this transition.
Hilary Benn (Leeds Central) (Lab)
Looking at the climate science, I do not suppose that a single Member of the House does not ask themselves, “How can we make the changes that are needed?” The Minister will be aware that the Committee on Climate Change said in November that emissions from homes are off track and we will need to replace gas with hydrogen boilers and supplementary electric heating. Given that about 80% of homes depend on gas for heating or cooking, how will that change happen?
Claire Perry
The right hon. Gentleman is right to emphasise homes, although they are responsible for only 15% of our CO2 emissions. In fact, the biggest nut we have to crack is industrial emissions, which is arguably much harder to do. There will be no one-size-fits-all policy on homes. There will be some decarbonisation of gas, some introduction of pure hydrogen, a move to electrification and a use of community heating or heat networks. Some amazingly innovative local authorities—Nottingham and Leeds spring to mind—are trying to design new forms of heating system into their local economies and home building programmes. That is how we will innovate and drive the cost down. I think that the announcement of no fossil fuel heating in new homes from 2025 will kick-start a revolution, particularly in reducing the cost of alternatives such as heat pumps.
