My Lords, I am grateful to my noble friend Lord Whitty for introducing this amendment and to the other noble Lords who have spoken in favour of it—or if not directly in favour, at least in favour of us having a debate about decarbonisation. I recall that a similar amendment was tabled by my noble friend Lord O’Neill of Clackmannan during the Committee stage of the Energy Act 2013. We had a good debate at the time, and the arguments which were put forward were important then and are even more important now. I say that because we all engaged with the Energy Act 2013 in good faith. We raised our concerns and we went forward on the basis that we hoped that we had a system that may be a transition to something more market-based and slightly less interventionist in order to encourage us to decarbonise our electricity system.
I apologise for stating the obvious, but the reason electricity is so important is that once it is fully or substantively decarbonised, it can then be used to decarbonise transport and heat in an effective way. It is not the only way, but it is one way. It is the sector with possibly the most commercially available technologies and certainly the widest range of known technologies, certainly at this stage, to help us. That is why electricity is focused on and why we have a 30% target for renewable electricity as opposed to 10% or 12% in the heat and transport sectors. It is right to focus on electricity.
This idea is definitely worthy of merit and I do not disagree with the noble Lord, Lord Deben, when he says that we have in the past debated a broader definition
of the decarbonisation obligation or decarbonisation target. In fact, that was rather exhaustively dealt with in the debates around the Energy Act 2013. The way it was left was that the Government may introduce a decarbonisation target for 2030 in line with the fifth carbon budget being set. I very much look forward to hearing some strong words from the Minister stating that that is still the Government’s intention: that a decarbonisation target will be set in 2016 once we have that fifth carbon budget in place.
For all the reasons given by the noble Lords, Lord Deben, Lord Teverson and Lord Whitty, we lack a moment of clarity to help shake people’s investment decisions beyond 2020. We have renewable targets to 2020, as part of the European renewables directive, but beyond 2020 there is big uncertainty as to what low carbon technologies, if any, will be supported by the Government. Therefore, there needs to be a framework. Why I like the idea of a decarbonisation obligation on the Government and on suppliers is because it does exactly what the noble Lord, Lord Deben, said, which is to create a market-based system.
I often find myself wondering whether I am Alice who has stepped through the looking glass. Here we are in a world where the Government—a Conservative Government—who are presiding over virtually the renationalisation of the energy system. There is no element of the energy system that is not now reliant on the Secretary of State to sign a contract of some sort or another, perhaps with the possible exception of some of the interconnectors, but even there it is quite highly regulated. Now any new clean capacity needs to be signed off by the Secretary of State with a contract for difference, and all the existing capacity receives capacity payments also through the Secretary of State’s gift. Here we are, very oddly, presiding over pretty much a state-run energy system, and here I am on the Labour Benches saying that we need a much more market-based system that allows more choice and for capital to flow to the most cost-effective ways.
It is an odd situation but that is where we are. So I press the Minister to help us to understand that the Government are sharing our objective, which is to move towards a slightly less interventionist system with more ability for a broader set of players to dictate how we meet our targets, which means the Government setting the framework, being clear about our objectives, but allowing a wider pool of people to find those solutions for us at least cost.
Amendment 35A is an interesting idea which proposes that rather than the Government taking on the obligation and the target, they should be passed down to the supply companies. It has some merit. It is worth noting that suppliers have been obliged to report on the carbon intensity of their electricity supply for some years now. They have a fuel disclosure requirement and an infrastructure and reporting mechanism that enables them to do that with certificates of origin. That enables them to calculate the carbon intensity of their electricity annually and report to Ofgem. Those numbers then probably sit on a website or in a document. Very little attention is paid to them which is a great shame because we are encouraging these data to be collected but doing very little with them. If we were to look at those numbers, sadly we would see that carbon
intensity has remained stubbornly similar over the past decade. We did very well in decarbonising when we had the dash for gas and replaced a lot of our old coal, but since then carbon intensity has just moved around, largely dictated by commodity prices where gas prices are higher than coal or vice versa. So there has not really been a grip on carbon intensity.
An obligation such as this would address that problem and mean that the full range of decarbonisation options, including fuel switching and phasing out of coal, would be incentivised in the most logical way forward. I am very grateful to the noble Lord, Lord Teverson. He and I have worked previously on the phasing out of coal and the use of performance standards to make sure that our old coal, in particular, is phased out in an orderly and certain way so that we can make room for clean investment. A decarbonisation obligation would help us to ensure that that transition out of coal took place. It is not the only way it can be done, but it would be a market-friendly way to meet the obligation because there would be an incentive not to purchase the coal that would count against the target. It would help to make it harder to hit the targets. The other benefit is that it would help renewables to stand on their own two feet and compete alongside other technologies. We would genuinely see which are both affordable and able to be supported by the general public.

I should state that this carbon intensity number is one that we as a country should care about. It is really the Committee on Climate Change that has made the carbon intensity of electricity something that is in the public discourse. It is worth noting that at around 400 grams we are able to shave off more than 150 grams simply by using our existing infrastructure more wisely. If we were to change the merit order and run gas ahead of coal we would take off up to 200 grams without needing to invest in anything new. That is why those numbers matter and why we should be scrutinising them.
I pay tribute to my ex-boss at Scottish and Southern, Ian Marchant, who now claims he has invented a new law—the Marchant law, which is that over 10 years the carbon intensity of our electricity should halve, so we should go from 500 to 250, from 125 to 75, from 400 to 200, or from 100 to 50. We should do that over a 10-year cycle, which would give us a good pathway and is certainly achievable with the range of technologies we have. Speaking personally, that includes nuclear, carbon capture and storage, gas, renewables; to cite President Obama, I am an all-of-the-above person when it comes to climate change, with the exception of unabated coal. There is a role for everything and we must try to ensure that we invest in those things that are delivering. That is the best outcome. We also need to act swiftly because, as we know climate change and the need to decarbonise is becoming ever more apparent and we need to move with alacrity towards decarbonising our energy fully. We should be leading the world in committing to do that.
I am very grateful to the noble Lord, Lord Whitty, for moving the amendment and for the contributions we have had. It has been a good debate and I look
forward to hearing from the Minister in relation to the broader question of decarbonisation targets, as currently described in the Energy Act 2013 and the interesting idea of including suppliers in this and getting them to apply their great understanding of the markets to help us to achieve those targets with the least cost.
