Graham Stuart – 2022 Speech on Burning Trees for Energy Generation
The speech made by Graham Stuart, the Minister for Energy and Climate, in Westminster Hall, the House of Commons, on 6 December 2022.
It is a pleasure to serve under your chairmanship, Mr Gray. I congratulate my hon. Friend the Member for North Devon (Selaine Saxby) on securing the debate and thank all right hon. and hon. Members for their participation.
My first reflection, having heard the tenor of the debate and the contributions so far, is that I have a bit of an uphill struggle to the persuade people in Westminster Hall of my case. It was noticeable in the contribution of the hon. Member for Southampton, Test (Dr Whitehead), given in his classically well-informed but downbeat style, that the position of His Majesty’s Opposition is to support the use of biomass. They think it does have a role, although the hon. Gentleman caveated that by saying that it was “not a large” contribution, which in the overall scheme of our energy use perhaps leaves a lot of unanswered questions. However, I welcome the fact that he said that.
My hon. Friend the Member for North Devon raised important questions about biomass sustainability. I welcome the opportunity to clarify both the type of material and the stringent requirements we have in place to ensure that we support the sustainable use of this valuable resource. Using sustainable biomass in energy generation in the UK’s power sector has helped to reduce the use of fossil fuels. In 2021, biomass made up 12.9% of total electricity generation and the flexible generation provided by biomass technologies helps to support and stabilise the grid. It is not comparable with renewables, which by their very nature are not dispatchable and available as and when they are required—unlike biomass.
The use of wood pellets for bioenergy production has attracted a lot of interest and it is right that operations are closely scrutinised. However, there are claims against wood pellet use for bioenergy from forests that misrepresent on-the-ground forestry practices. That is short-sighted and ignores the environmental and social benefits of sustainable forest practices and the role that forest-derived biomass plays in supporting them.
Policy decisions need to be based on facts and rigorous evidence gathering, not on inaccuracies and misconceptions. The use of biomass from sustainably managed forests in well supported by evidence and experts such as the International Energy Agency, which is the global authority on energy, and the Intergovernmental Panel on Climate Change, which I would have thought that Members present would regard as being particularly well placed to make judgments on the balances that need to be struck in coming up with policy, yet the tenor of today’s debate is to dismiss these global experts and the different organisations that have looked at this issue extensively and come to the conclusion that the use of biomass is sustainable and right.

I will make a little more progress, if I may.
It is important to remember that wood used for bioenergy is not high-quality and high-value timber. Although it has been said repeatedly in the debate that wood used for bioenergy diverts material away from other uses, the opposite is true. In response to my hon. Friend the Member for St Ives (Derek Thomas), who comes from the construction industry, the value of timber for other uses is much higher than the value of timber used for waste, so there is no economic rationale for using it.
Wood pellets and Drax purchases do not compete, because they do not offer the same financial return. The idea—it has obviously been seeded, taken root and taken off, because I hear it again and again—that people are, in a sinister way, diverting excellent wood from uses for which they would get paid a lot more money to a use for which they get paid a lot less has spread, and it has become a conspiracy. In fact, bioenergy use does the opposite: it supports sustainable forestry. It supports the very forests that can supply wood panelling and construction material. We can ensure that it is part and parcel of delivering a stronger forestry industry around the world, and that we can have more wooden-constructed homes, as my hon. Friend the Member for St Ives suggested we should have.
Barry Gardiner
I am sorry to interrupt the Minister in his rhetorical flow, but does he accept that two of the licences that Drax has utilised in British Colombia were for areas of primary forest that have been destroyed? Those areas—in one case, more than one square mile of primary forest—have been clear-felled, and Drax has denied it.
Graham Stuart
I will write to the hon. Gentleman on that specific issue, as it is right that I give him a proper answer. On investigation, we do not find that the allegations that “Panorama” made are fundamentally sustained. The general process involves thinnings. Every managed forest has to be thinned in order to be sustainably managed, and thinnings sometimes include whole trees—that is the nature of forest management. If we do not do it, it does not have the desired effect. It is worth saying again to my hon. Friend the Member for North Devon that young, vigorous stands grow and sequester carbon at maximum speed. As stands get older, the tree canopy closes and individual trees begin to die off from self-thinning and other causes. Very old forest stands can reach a carbon-neutral equilibrium, whereby trees die and decay at approximately the same rate as they grow back.
It is worth saying that before thinnings were used for bioenergy and turned into pellets, they were typically burned to get rid of them. The idea that the use of biomass is taking away fundamental primary forest, which is being cut down even though there are better uses for it, is false, but I will write to the hon. Member for Brent North (Barry Gardiner) about the specifics of that. It is always possible that there are exceptions, but Canada and the United States have really strong forest management and sustainability practices, regulations and laws. We have looked closely at the issue, and if they wish to keep this business going and manage the crops of these forests, they have every incentive to maintain them.
I say to my hon. Friend the Member for North Devon that we could do with bringing in some experts, and I will hold a meeting. Let us have the scientists in and discuss some of this stuff—it would be an opportunity to talk about it further.
Selaine Saxby
I thank the Minister for giving way on this point, although I am very disappointed by the stance he is taking. Will he invite the 600 scientists who wrote to the Prime Minister earlier this week with their very detailed analysis? The professors with whom many of us in this room have spent much time understand that the science has evolved and that some of the information we used back in 2014 is no longer correct. We need to re-evaluate things; we cannot just get stuck on what we used to do in the past.
Graham Stuart
I entirely agree with my hon. Friend. We must not get stuck in the past, and we need to have a thorough and proper examination of the issues. That is why, as one small contribution to that, bringing in the Government experts and the people we are listening to would be a useful way to carry on with this and make sure that we are making the right judgments overall. The last thing we want to do is get this wrong. As successive Members have said, there is a substantial subsidy involved for a start, and we want to ensure that whatever we are doing is the most sustainable, both economically and environmentally, for the good of the country. It is well worth having that conversation.
Forest sites are harvested to produce fibre for multiple products, such as timber, plywood and oriented strand board, among others. Those industries invariably pay more for the fibre. Wood pellets for bioenergy make up only a small portion of a harvest—notwithstanding the talk of 27 million trees—and help to maximise the benefit of each harvest. It is, effectively, a harvest—an energy crop, and a by-product energy crop of the main product, which is timber produced for other uses.
Material that is not wanted by sawmills can be used when it does not have a suitable destination in the sourcing regions—for example, when there is a lack of local pulp and paper mills or other suitable industries. The destination of lower-quality material such as low-grade roundwood that is unsuitable for use in sawmills depends on the types of industry present around the sourcing area. If there is a pulp or paper mill nearby or a wood panel producer, material suitable for use in those industries is taken there, as those end users pay more for the fibre than wood pellet producers do. It is simply not economical for the harvester to sell those materials to the pellet mill if other, higher-paying industries are present.

I give way, for the last time, I think.
Barry Gardiner
The Minister has been generous in giving way, and I appreciate that. Will he address an issue that many Members have raised, which is the payback period and the cycles not being short enough to achieve the emissions reductions in the timeframe that the climate will allow?
Graham Stuart
The hon. Gentleman, as so often, has put his finger on the central point. We cannot do this by looking at an individual tree. We look at the whole forest and different parts of it, which are of different ages. That forest is harvested in an ordered way. We need to look at the whole forest, and as long as there is replanting—that is precisely what the sustainability criteria are about, and those are applied in Canada, America and elsewhere—and the overall carbon sequestration is maintained, and indeed over time preferably increased, there are no emissions, effectively.
Let me return to the point source emissions at Drax and say that that is why we do not count them. As long as the overall picture is in balance—this is only a by-product of the energy crop and of the main use, which is for timber—we can see, straightforwardly, that it is right not to view that as having emissions. That is what the policies are in place to try to ensure.
I must allow two minutes for my hon. Friend the Member for North Devon, and I look forward to a further discussion of the matter. As has been said, I have been in the job for only a relatively short time, and, as Members can tell, I am seized of a certain view, but I am certainly interested—
Sammy Wilson
So was a previous Minister.
Graham Stuart
We have had those quotes, which might or might not have been accurate. My right hon. Friend the Member for Spelthorne (Kwasi Kwarteng) did then say that he fully supported Drax and the policy of the Government. He was not a junior Minister; he was Secretary of State, so if he had a different view he could have said so. I do not suppose he was too constrained.
Anyway, I look forward to further examination of the issue, but I should give the floor to my hon. Friend the Member for North Devon.
Selaine Saxby
I thank you, Mr Gray, for chairing the debate, and my colleagues for their contributions. I suspect we will return to the issue, and I would be happy to join the Minister in doing so.
As we move through the transition to net zero, it is vital that we understand that things are going to change, that the science has changed and that we are moving forward. When people first burned coal, they did not understand the damage they were doing to the planet, and I think the same is true for wood pellets. In 1959, plastic bags were invented to stop us cutting down trees to make paper bags, and we recognise now that that probably was not the right decision.
I hope that as the Minister reviews the matter and considers the release of his biomass strategy, he will find those same advisers who persuaded the former Secretary of State that importing trees to burn is not a sustainable practice in view of our intention to get to net zero by 2050. On the current path, we are simply not going to achieve that.
