The Parliamentary Under-Secretary of State, Department for Business, Energy and Industrial Strategy (Lord Henley) (Con)
My Lords, I first thank the noble Baroness, Lady Jones, for securing this debate, which has been of high quality, even if all speakers have been limited to a mere three minutes each. In fact, perhaps that made the quality even higher, I do not know; it has certain advantages.
I will make the point, in response to the noble Baroness, Lady Lane-Fox, and to others who are worried that the debate is not happening, that the debate is very much happening. This might just be one very tiny, minuscule part of it, but we know—mention was made earlier of demonstrations by schoolchildren and others—that the debate is happening up and down the country. As other noble Lords put it when they talked about local authorities, it is happening at local authority level.
A number of questions were raised, and I will not be able to respond to all of them this afternoon. I have been criticised by my noble friend Lord Caithness, quite rightly, for failing to respond in a previous debate to his questions about the effect of the shifting of magnetic north and cosmic rays on global warning. I will write to him in due course, but he will recognise it is quite a difficult thing to respond to because there is not much evidence.
I also give an assurance to all those who spoke that the Government are aware of the threats posed by climate change, and that we respect the sense of urgency. We understand it, agree that there is an urgent need to do things, and accept that impacts are already being felt. The Government are responding, and we continue to demonstrate strong leadership worldwide—I will get on to that later on—to tackle it at home and abroad.
I will start with the IPCC report on climate change, and what our response will be. We are already seeing the impacts of climate change—the hottest days of the year are getting hotter, and minimum temperatures are getting milder. There is a clear trend, and I remind the noble Lord, Lord Greaves, that we have not always had the stable temperature he seems to think we have. I refer him to the late Middle Ages, when there were vineyards in the south of England. The same was true in Roman times, with a colder spell in between. After the Middle Ages warm period, we had the mini-ice age of the 17th and early 18th centuries—so the climate has always changed, but something is happening at the moment. We agree that there is a trend and that something needs to be done; and we know that, without action, rising temperatures will result in even more serious effects.
For those who think we have been slow off the mark, following the IPCC’s report last October, within a week we had requested advice from the Committee on Climate Change on the implications of the Paris agreement for the UK’s long-term emissions target. I can assure the noble Lord, Lord Teverson, that when it comes out in May—I was not sure of the precise date but he said 2 May, which I think is right—we will respond as appropriate. He would not expect me to say at this point that we will accept everything the committee says. It would be a rash Government, possibly a Liberal Government, who would take that line. As an aside, I do welcome his genuinely positive approach to what the Government are doing—and I think one can take a positive approach.
The IPCC report offered a stark warning that our current rate of warming could see us reaching 1.5 degrees, possibly as soon as 2030. That would have devastating effects—it could do a great deal to our infrastructure, food, water supplies and so on. It went on to point out that up to 90% of coral reefs could be lost, with irreversible effects such as melting ice sheets that would continue to have impacts for centuries to come. The report is a rallying cry for Governments around the world to do something—to innovate, to invest and to raise ambition. It is therefore right that we should follow the scientists. As all noble Lords have made clear, we are now witnessing a groundswell of public concern. There is an increased sense of urgency from people all around the country—I mentioned the recent demonstration by schoolchildren—and more vocal demands for action.
The Government absolutely share their mission to solve this global challenge. To do so, we are taking action both domestically and internationally, as the noble Baroness, Lady Jones, asked us—because there is no point in us just doing things domestically if we do not try to provide the international lead that I believe we can and will. I shall touch on both of those.
On domestic action, our carbon targets are among the most stringent in the world and have provided a blueprint for climate action internationally, with elements of our framework emulated by many other leading nations. We should be proud of our record, which was cited by the noble Lord, Lord Grantchester when he stressed that we have reduced emissions since 1990 by 42% while—this is the important thing—growing the economy by 72%.
But there is more to do. In 2017, we published our Clean Growth Strategy. The noble Baroness, Lady Jones, called it “a very poor effort”. I have to say that I do not agree. The important thing to remember about the strategy is that “growth” appears in its name. As I have said, we have seen a cut in our emissions by 42% while continuing to grow our economy by 72%. The strategy set out our policies and proposals for meeting future carbon budgets and the illustrative pathways for the 2050 target. It explains just how the Government are investing more than £2.5 billion to support low-carbon innovation from 2015 to 2021, building on the UK’s world-leading expertise in areas such as offshore wind—where we have seen the price of offshore power come right down—and electric vehicles.
The noble Baroness, Lady Meacher, asked about research that we are doing in that area. It is important to emphasise what has been achieved. For example, the noble Baroness will see what a success story solar has been over the years as a result of government intervention, with deployment and cost reductions exceeding expectations to the point where two large-scale projects have already deployed without subsidy from the Government, and the planned construction of two more large-scale, subsidy-free solar projects has recently been announced. That is as a result of the investment that government have made and the encouragement and support that we have given—again, we have seen the price drop. I cite these just as examples; there is much more research in other areas.
The noble Baroness asked about storage, which I agree is the vital thing to address if we are to make renewables such as solar and wind, which are necessarily variable, of great use. Yes, research on hydrogen has been going on. I have seen some serious work being done by Heriot-Watt University in Orkney, where they are beginning to power ships using hydrogen. I also went to the Clyde to see some new CalMac ferries being built that will be powered by hydrogen. There is a future for hydrogen there; there is possibly a future for hydrogen in cars. Electricity might take over—I do not know—but all avenues need to be explored, and the Government will play their part in that. We are certainly exploring hydrogen’s potential to deliver against our own clean growth aims.
I see that I am running out of time so, rather than going on with examples of the sort of research that the noble Baroness asked about, I will quickly move on to say a little about the international position. I am very grateful for what the noble Earl, Lord Sandwich, said about welcoming our international role and the role that we can play. As I said, what we do in the UK on our own is not going to make much difference. We believe that the United Kingdom has played a key role internationally in demonstrating leadership through its domestic action, through climate diplomacy and through financial support, and that our world-leading economic, scientific and technical skills are shaping the global debate. I am proud to say that United Kingdom negotiators played a central role in securing the Paris agreement in 2015, while the UK scientific community was at the heart of the international effort behind the IPCC’s special report.
Our world-leading climate science programmes are helping developing countries to mitigate and adapt. We are fully aware of the concerns that the noble Earl and others raised about the problems that other countries are having. We are providing at least £5.8 billion between 2016 and 2020, helping over 47 million people to cope with the effects of climate change. This September the United Kingdom will lead the resilience stream at the UN Secretary-General’s climate action summit. Our ambition is to drive transformational change in the way that we think and take decisions on resilience, enabling people and the planet to adapt and cope with shocks and stresses.
I conclude by reiterating the determined action that the United Kingdom Government are taking to tackle climate change both domestically and abroad. Our sense of urgency is real and the challenge that we face is great. The IPCC report made that clear, and it is necessary for us to build on that momentum, acting now to build a brighter future for ourselves and for our children.
