It is a great pleasure to serve under your chairmanship, Sir Christopher, and to listen to this excellent and important debate. I begin by congratulating my right hon. Friend the Member for Spelthorne (Kwasi Kwarteng) on securing it. Of course, I come to this debate with some trepidation, as I am facing someone who did my job previously and then, unlike me—yet, anyway—went on to be Secretary of State at what was then the Department for Business, Energy and Industrial Strategy. He made immense progress on our path to net zero and energy security. My right hon. Friend the Member for Spelthorne oversaw the publication of the landmark, world-leading net zero strategy. The independent Climate Change Committee described it as 'an ambitious and comprehensive strategy that marks a significant step forward for UK climate policy' and as 'the world's most comprehensive plan to reach net zero'. It is worth highlighting a couple of points. When we came to power in 2010, just 7% of this country's electricity came from renewables; now it is well over 40%. The issue of insulation and the number of houses being insulated was also raised. I do not know why the Liberal Democrat member who raised it, the hon. Member for Tiverton and Honiton (Richard Foord), is no longer here for the winding-up speeches, but anyway—he raised it before leaving the Chamber. It is worth noting that in 2010 the figure was just 14% and by the end of this year I expect that 50% of homes will have reached energy performance certificate level C or above, which is a huge—indeed, transformative—change, albeit one that needs to go much further and faster. My right hon. Friend the Member for Spelthorne oversaw COP26, which was the biggest summit that this country has ever hosted. It brought together 120 world leaders and over 38,000 key figures from Governments, civil society, businesses, youth and more, in order to tackle the urgent challenge of climate change. We have met all our carbon budgets to date and we are the first major economy to legislate for net zero—done under this Government. So this country is more on track than almost any other country and certainly more than any major economy on earth. That is the context that people could be forgiven for not realising was in fact the case from the rather adolescent contribution of the Scottish National party spokesman. I will leave to one side any comments that the chairman of the Climate Change Committee has made about the Scottish Government's performance in meeting their climate targets, because doing otherwise would be to descend to the level that the SNP spokesman stayed at throughout his speech. That is an excellent question—we have exceeded every carbon budget to date. We not only have the net zero strategy but we had the net zero plan on 30 March, setting out how we will do it. Of course that stretches through to 2037. Not every aspect of the way in which we will fulfil that aim has been set out to date—people would not expect them to be 14 years before that date—but we are on track. What we have to do is make sure we stay on track. I would not try to represent to the House today anything other than the fact that it is an extremely challenging business to ensure that we continue on track. That is what we are working on flat-out. Our net zero ambition needs strong public and private partnership, and we are forging these links in a number of ways. Government policy and funding commitments are already leading to real outcomes, and we are leading the world in so many ways, not just on offshore wind. The Government are committed to accelerating renewable electricity deployment. The Powering Up Britain package sets out our delivery plans for meeting those ambitions. It includes important announcements on a range of technologies, including up to £160 million of new funding to kick-start our investment in port infrastructure to deliver on our floating offshore wind ambitions, and a new solar taskforce to drive deployment of that important technology as we seek to increase that fivefold by 2035. We launched the taskforce on 25 May, getting key players from Government, industry, regulatory organisations and other relevant organisations round the table to drive forward the actions required to deliver that ambition of deploying 70 GW of domestic and industrial rooftop and ground-mounted solar by 2035, all while cutting installation costs, boosting British skills and jobs, and improving grid access to support a solar power revolution. We are looking at the Xlinks project. We have set up a team to look at it with no further commitment other than to make an assessment. It will be reporting to me shortly on that. We will look at the outline business case going forward. We are looking at it; I do not want to go further—positively or negatively—than saying that. We have heard mention in the debate of the need to improve the energy performance of homes across the country. Notwithstanding the transformation we have brought about—it is not enough—that is why we have established a new energy efficiency taskforce to drive forward improvements. That is why we are spending £12.6 billion over this Parliament and up to 2028 to support and provide long-term funding and certainty, supporting the growth of supply chains and ensuring that we can scale up delivery over time. Only yesterday I visited Octopus Energy's centre, looking at how that company is trying to design heat pumps to be cheaper to install and more efficient, so they can drive the cost down and speed up the time it takes to install them, thus making the decarbonisation of heat in homes, which is a thorny and challenging subject, more realistic and deliverable. The delivery of net zero relies on strong business action. That is why we brought together senior business and finance leaders into a new strategic net zero council co-chaired, alongside myself, by Co-op Group CEO Shirine Khoury-Haq. It includes Carl Ennis, CEO of Siemens; Ian Stuart, UK CEO of HSBC; Chris Hulatt, the co-founder of Octopus Investments, and others from UK business. The full membership reflects the cross-cutting nature of our net zero challenge. The next meeting is planned to be held in No. 10.
