Waste: Incineration

Debate between Baroness Hayman of Ullock and Lord Krebs

Tuesday 22nd October 2024 Lords Chamber

[Baroness Hayman of Ullock (Lab)]

As I just mentioned, we are looking to do a review right across the piece on this, so anaerobic waste will certainly be part of that.

[Lord Krebs (CB)]

My Lords, it is all very well to incinerate waste, but does the Minister agree that a real priority should be to reduce the amount of waste that we produce as a country? The real way to deal with this problem is just to produce less waste.

[Baroness Hayman of Ullock (Lab)]

It is a really important point that the noble Lord makes. If we are moving to a more circular economy, as this Government want, we have to see less residual waste being generated —in fact, less waste as a whole. There is a statutory target to effectively halve residual waste by 2042 from 2019 levels, but there still will be an estimated 17.6 million tonnes of residual waste to manage in 2042. Therefore, we have to look at the bigger picture. How do we actually reduce waste overall?

Genetic Technology (Precision Breeding) Bill

Debate between Baroness Hayman of Ullock and Lord Krebs

Report stage
Wednesday 25th January 2023 Lords Chamber

[Baroness Hayman of Ullock (Lab)]

My Lords, I shall introduce my amendments in this group, Amendments 11, 27, 29 and 30. I thank the noble Baroness, Lady Parminter, and my noble friend Lord Winston for their support. I declare my interest as laid out in the register as president of the Rare Breeds Survival Trust.

During our Committee debate, the Minister stated that the Government’s intention was to take a step-by-step approach, particularly around the introduction of animals, and that the Bill had the ability to do so. Our concern is that we have heard no clarification as to how this will actually work. By what means do the Government intend to introduce provisions related to distinct species, rather than the “relevant animals” as a class, under the Bill as currently drafted? Despite the Minister’s assurances, we still have no guarantee that this step-by-step approach will actually happen.

My Amendment 11 would set this expectation on the face of the Bill. Combined with my Amendments 27, 29 and 30, the effect would be to prevent a precision-bred animal being released until it had met the date condition provided by my new clause, which would follow Clause 47. This proposes that, for farm animals, the date is no earlier than 1 January 2026, and for other animals, no earlier than 1 January 2028. Also scientific evidence must support this extension: if it does not, the date could be put back further. I just say to the noble Baroness, Lady Bennett, that this is not an automatic introduction at that date; it is just putting the step-by-step approach on the face of the Bill.

The reason I have tabled these amendments is that, whether we agree that animals should be included or not, clear concerns were expressed during our Committee debates as to when they should be included, how quickly they should be included, and whether all animals should be included at the same time. We believe there is insufficient detail in the Bill regarding concrete provisions around timeframes: many of them are vague and noncommittal. Much of the preparation that we believe is necessary for a regulatory framework for animals has not yet been properly carried out.

When this issue was debated in Committee, the noble Lord the Minister said:

“All I can do is assure noble Lords that nothing will happen before we are in the right position to do it … The priority will be to try to do this for farmed animals first, and we want to make sure that we are operating a step-by-step approach. If we put it in the Bill, it may be too prescriptive, because we are in a fast-moving area of science, and it may constrain the ability of the scientific community to progress this if we do it in the wrong way.”—[Official Report, 12/12/22; col.503.]


We listened to the Minister’s words and, in order not to tie the Government’s hands or constrain the scientific community if there is clear evidence, for example, of a scientific breakthrough in tackling bird flu, the amendment allows for flexibility. An accelerated timetable should come in only if scientific opinion supported this. So we have not set these dates in stone in either direction.

I hope the Minister can see that we are taking a constructive approach to trying to put step-by-step on the face of the Bill. However, if he is not prepared to accept our amendments, I intend to seek the opinion of the House.

[Lord Krebs (CB)]

I thank the noble Baroness, Lady Parminter, for her courtesy in giving way. I will make only two brief comments. The first addresses the point that the noble Baroness, Lady Bennett of Manor Castle, raised, particularly the reference to the workshop that I helped to organise last Friday, where we had a number of experts giving us their take on the science. It is very often—in fact, usually—the case that scientists do not absolutely agree on everything; that is just the way that science is. When you go as a scientist to a conference, you do not expect everybody to say, “Fantastic, your research is absolutely superb”. People criticise it and challenge you and say, “Why are you doing that in this way and not some other way?” But there is sometimes a centre of gravity of opinion. Science goes through different phases. There may be no agreed position and gradually over time it is possible that a position consolidates in a particular way.

I think it is fair to say that Dr Michael Antoniou, to whom the noble Baroness, Lady Bennett, referred, is probably not in the centre of gravity of current opinion on the safety issues and other technical aspects of gene editing. So while I absolutely applaud the noble Baroness’s point which raised the diversity of opinions in the scientific community, I do not think your Lordships should be too swayed by a particular individual’s point of view, because I do not think it is the centre of gravity of scientific opinion.

My second, very brief point concerns timescales and is related to the amendment in the name of the noble Baroness, Lady Hayman of Ullock. One can see this in two ways, as her introduction to her amendments implied. You could see it as putting the brakes on—do not rush too quickly before you are sure—as the noble Baroness, Lady Bennett, would wish us to do. On the other hand, towards the end of her speech, the noble Baroness, Lady Hayman, said, “We don’t want to hold things back”. On the one hand we do not want to rush, and on the other hand we do not want to have the brakes applied too sharply.

I am trying to anchor that in a bit of reality. As far as I am aware—I was told this at the meeting last Friday by Professor Bruce Whitelaw, director of the Roslin Institute in Edinburgh, which is the UK’s leading centre for this sort of technology in animals—in the US, the Food and Drug Administration is already reviewing a licence application for gene-edited pigs. The animal genetics company, Genus, in collaboration with the University of Missouri, has developed a pig that is totally resistant to the virus that causes porcine reproductive and respiratory syndrome—PRRS for short. So the question in assessing the amendment proposed by the noble Baroness, Lady Hayman of Ullock, is, would that amendment hold up the commercialisation of this pig, if the FDA and the relevant bodies in the UK approved it?

Given that it would improve pig welfare, because PRRS is not a pleasant disease, and save the pig industry a very large amount of money—an estimated $2.5 billion a year in Europe and the US alone—do we want accidentally to place a barrier on that kind of development through timescale limits? I do not land on one side or the other; I just think it is useful to have a real-life example of what is going on. My question to the noble Baroness, Lady Hayman of Ullock, is this: if this PRRS-resistant pig came to market before 2026, would that count as an example of where the 2026 hurdle should be removed, because it is ready to go, or would she want to keep it in place? The question on the other side is whether it will realistically go from FDA approval to commercialisation in about three years. I am not trying to land on one side or the other, just to anchor this in a specific example which may help us think through our response to the proposed amendments.

[Baroness Hayman of Ullock (Lab)]

Just to come back on that, proposed new subsection (4) in my amendment says:

“The Secretary of State may, by regulations, amend the dates listed in subsection (2)”—


the dates I read out—

“if the requirement under subsection (3)”,

which is the evidence condition the noble Lord is talking about,

“is met before the dates”.

There is flexibility in the amendment to bring those dates forward if that scientific evidence is there.

Genetic Technology (Precision Breeding) Bill

Debate between Baroness Hayman of Ullock and Lord Krebs

Committee stage
Monday 12th December 2022 Lords Chamber

[Baroness Hayman of Ullock (Lab)]

My Lords, I thank my noble friend Lord Winston for introducing these amendments. This group explores why “genome editing” has been changed to “Precision Breeding” in the Title of the Bill and throughout it, when, as my noble friend pointed out, it has no scientific meaning. As he said, there is no such thing as precision in biology. He clearly, and in some detail, expressed his concerns about the implications of the Bill. As he also said, as yet there has been no detailed debate during the Bill’s passage around the science. I am sure that we will have that debate in your Lordships’ House, as there are some very eminent people here who know far more about the science than I could ever hope to learn.

My noble friend’s amendments quite rightly probe the Government’s thinking around the terminology. Importantly, he raised the fact that what we need as an outcome of the Bill is the breeding of plants and animals that are free of risk. Again, he talked about the implications of hereditary traits and the fact that the Bill’s focus is on releasing organisms. We need to think much more about how that is happening, and what the implications are as we put the Bill through into becoming an Act.

We know that in the Bill and during the debates—

[Lord Krebs (CB)]

I am sorry to interrupt the noble Baroness, but I want to make the point that when we talk about “free of risk”, we have to get things in perspective. In so-called conventional breeding, the parent seeds or germline are often irradiated to create a large number of random mutations and then a new cross-bred strain is produced. That often involves shuffling maybe 20% or 30% of the genome and is not regulated at all. When we say “risk free”, we know that conventional breeding is not risk free. The Braeburn apple was introduced 30 or 40 years ago as a new variety—a hybrid of two earlier varieties—without any testing, and that could have had detrimental consequences for human health or the environment. Nothing is risk free, so let us get risk in proportion.

--- Later in debate ---

[Baroness Hayman of Ullock (Lab)]

My Lords, my Amendment 19 would require that a precision-bred organism has been developed to provide a public benefit if it is to be released into the environment. The benefits that are listed in my amendment include, but are not limited to, producing food in a way that protects the natural environment and managing crops or livestock in a manner that mitigates or adapts to climate change. Amendment 21 in this group prevents the release of a precision-bred organism unless its genome has been sequenced and the features that have resulted from the use of modern biotechnology have been recorded. I am looking forward to hearing more about that as well.

Earlier, we talked briefly about climate change and how plants in particular can be adapted to support the future needs that we will have in producing sufficient food. It is important that we find ways to maintain and improve the efficiency, security and safety of our food system while we are developing new legislation and that at the same time we address the environmental and health damage that our modern food system has sometimes created. This Bill gives us an opportunity to look at that and see what we can do to improve those areas alongside the other benefits that people have talked about and to mitigate any adverse impacts that could counteract that.

This Bill presents us the opportunity to create a world-leading regulatory framework that other countries could follow as they develop these kinds of technologies that would provide a clear public good. We recognise that our laws need to be updated to match current scientific understanding. We talked about that earlier in the debate. We want our scientists to succeed, but we also want them to use their skills for good here in the UK. I know that is broad terminology, but I hope noble Lords understand what I mean by this.

To get the legislation right, the Government have to balance certain risks and benefits. We need to have consumer confidence and business confidence; otherwise, all the benefits that could come from the Bill may not happen in the way that we would like. It could mean that we get improvements to environmental sustainability and better food security. A lot of this Bill is obviously around food, but how does it fit in with the much bigger picture that the Government have debated alongside the food strategy, which we all saw—was it last year? I am trying to remember how long ago it was. We talked earlier about different legislations interacting. How will this Bill work with the food strategy? Many of the recommendations were about how our modern food system could be improved and what public benefit could come from the way we farm in future.

The Nuffield Council has made recommendations in its document. One part of that is around aspirations for the UK’s future food system—something that is in the minds of a lot of people who have real influence over the way this technology could be looked at and developed in the future. I was also particularly struck by the evidence given to the Commons Public Bill Committee by Bill Angus, who is a wheat consultant. He noted that the motivations behind the work that he does as a wheat breeder and as vice-chair of the International Maize and Wheat Improvement Center in Mexico can be quite different; there are strong passions that drive both ways of working.

We also know that the Crop Science Centre in Cambridge has done interesting work focused on improving the sustainability of our farming systems—in particular, removing the need for inorganic fertilisers. To me, these are the kinds of areas where gene editing could bring significant benefits for the environment, the sustainability of our food systems, and reducing food insecurity across the world. The noble Lord, Lord Cameron, mentioned these issues in his earlier speech.

It is important that we look at how gene editing could be used for good, because we also know that it can be used for ends that, to many of us, would not be so desirable. Evidence from Compassion in World Farming was very interesting in this area. It talked about some of the harms that traditional breeding has caused—I will not go into detail, as we have heard about that today and at Second Reading. It is important that we work for the public benefit and that the Bill is not used to breed animals in a way that would mean they suffer more or be made to tolerate harsher conditions; the Minister mentioned this earlier. It is important that those questions posed in my amendments are taken account of. How can we ensure that the technology is used for good here in the UK?

There is also the question: who decides what that good might be? We will come on to debate that more to some extent in group 8, where we look at the animal welfare tests, for example. There are also questions around the development of herbicide-resistant crops. Do they allow more herbicide to be used? Is that a good thing? There need perhaps to be more tests in the Bill to make sure that some of the roads that we do not want to go down are not roads that we can go down.

My amendment would create a public benefit test before precision-bred organisms could be authorised and released. It is important that the governance is correct to manage that. Professor Sarah Hartley of the University of Exeter said in evidence:

“The Bill enables science to develop in this area, but it does not enable us to direct the science and technology towards doing any good.”—[Official Report, Commons, Genetic Technology (Precision Breeding) Bill Committee, 30/6/22; col. 123.]


That is the area that I am trying to look at and ask noble Lords to consider. How would we achieve that? At the moment, it is driven too much by market forces. In making legislation, we have to ensure that we guard against those who are, perhaps, not so interested in the good—the public benefit—that can come out of it but looking just at the market forces. We believe that the Bill could be strengthened through this amendment, and the Government’s stated aims, which the Minister has said he wants to achieve, could be encoded within the legislation itself. I beg to move.

[Lord Krebs (CB)]

My Lords, I thank the noble Baroness, Lady Hayman of Ullock, for introducing this amendment so eloquently. I have added my name to it. In fact, I felt that the amendment was almost unnecessary because, earlier this evening, the Minister referred to precision breeding as being used to create public good—I think I am right in saying that. The amendment tries to flesh that out and ask what is meant by “public good”.

It goes without saying that one objective of farming is to produce food or other farm products. Precision breeding will be used to increase the efficiency, and maybe the productivity, of farming in this country. My noble friend Lord Curry of Kirkharle, who is not in his place, made a useful comment earlier about what is meant by productivity in farming.

It goes without saying that one objective is to increase efficiency and productivity: that is the “more” bit of “more with less”. Equally important, and what the amendment is about, is enshrining the “less”: less harm to the environment and to people. We have been through many times the kind of harms to the environment that intensive agriculture has delivered, and we hope that precision breeding will be used to reverse those harms rather than augment them.

The noble Baroness, Lady Hayman of Ullock, also raised the important point of how bits of the jigsaw fit together. She referred to Henry Dimbleby’s national food strategy. I would be interested in knowing from the Minister whether some of the recommendations that Henry Dimbleby made will be implementable or, indeed, supported by the Bill if it goes through—as I hope it will, possibly with some modifications.

In a way, this is almost uncontroversial. We all accept that there have to be public goods that are supported by precision breeding; that has to be balanced with increasing productivity and efficiency of agriculture; and what we are trying to do here is spell out what those public goods are and should look like. I very much look forward to the Minister’s response.

Environment Bill

Debate between Baroness Hayman of Ullock and Lord Krebs

Committee stage
Monday 21st June 2021 Lords Chamber

[Lord Krebs (CB) [V]]

My Lords, one could argue that what is good enough for Sir David Attenborough is good enough for this Bill. Sir David’s 2020 TV programme “Extinction”, in which he talked about biodiversity, was watched by 4.5 million viewers on its premier. Those people, and the millions more who have watched it subsequently, will have some idea of what biodiversity is.

Although I do not support this amendment for the reasons that my noble and learned friend Lord Hope of Craighead so clearly articulated, I am grateful to the noble Lord, Lord Blencathra, for tabling the amendment, because it provides me with an opportunity, following the noble Baroness, Lady Bennett of Manor Castle, to ask the Minister to clarify precisely what the Government mean when they talk about biodiversity. As my noble and learned friend Lord Hope of Craighead said, words do matter. If the Government are to maintain the term “biodiversity” in this Bill, which I hope they will, please could they explain what it actually means?

I am now going to get a little bit technical. Ecologists recognise a number of different, but interrelated, meanings of the word “biodiversity”. At its simplest, it refers to what is called “species richness”—simply the number of species inhabiting a defined geographical area, such as England. A more sophisticated variant of species richness takes into account the relative abundance of different species. On this measure, an area populated by one extremely common species and, say, five very rare ones will be less biodiverse than if all six species were roughly equally abundant.

As the noble Baroness, Lady Bennett of Manor Castle, has already said, biodiversity can also include genetic diversity within a species. For instance, one might be particularly interested in preserving subspecies that are unique to this island, such as the native pied wagtail, motacilla alba Yarrelli. Furthermore, biodiversity might encompass the genetic distinctiveness of species, by placing a premium on species with no close living relatives on the planet, or on endemic species, such as eudarcia Richardsoni, a micro-moth found only in Dorset.

Finally, biodiversity might encompass the diversity of habitats, such as woodland, heath, peatbog and intertidal marshes, found within a geographical area. Many ecologists distinguish between what they call alpha diversity—species richness within a habitat—and beta diversity, which is diversity between habitats.

I hope that the Minister, in his response, or afterwards in writing, will explain what the Government mean when they talk about biodiversity. At the same time, it would be helpful if he could explain the difference between biodiversity and species abundance, as introduced in Amendment 22, which we will debate later.

[Baroness Hayman of Ullock (Lab)]

My Lords, this has certainly been an interesting discussion around the proposal of the noble Lord, Lord Blencathra, to change the wording of the Bill to use the term “nature” instead of “biodiversity”. I can understand why he would want to propose this change, as it is an easier concept for many people to grasp and understand, as many noble Lords have said during our discussion. However, the Minister did explain in his winding-up speech on Second Reading that the two terms are not exactly the same. The noble Earl, Lord Caithness, referenced the example that the Minister gave:

“Planting a Sitka spruce monoculture might give us more nature, but it would not give us more biodiversity”—[Official Report, 7/6/21; col. 1308].


A number of noble Lords have talked about definitions and the definition of “biodiversity” as opposed to the definition of “nature”. I would like to thank the noble Baroness, Lady Bennett of Manor Castle, and the noble Lord, Lord Krebs, for providing us so much information. I have learned an awful lot more in this debate than I was expecting. A number of noble Lords have looked at dictionary definitions, so I thought I would add to this by having a look at what the Oxford English Dictionary has to say. It describes “nature” as

“The phenomena of the physical world collectively; esp. plants, animals, and other features and products of the earth itself, as opposed to humans and human creations”


whereas—I would be interested to discuss this further with the noble Baroness, Lady Bennett of Manor Castle, at some point—the dictionary describes “biodiversity” as

“the variety of plant and animal life”.

So these things are different, and my thinking is that the Oxford definition seems to show that “nature” is a broader concept and “biodiversity” fits within that. Therefore, I am not quite sure how helpful Amendment 261 will be.

This is a really important Bill, and, as my noble friend Lord Rooker said, clarity as to exactly what is meant by the wording and terminology in this Bill—and in all legislation—is essential to avoid confusion and potential legal challenge. I am sure that the Minister will be able to provide us with more detail on the wording used and the way that the decisions have come, but noble Lords have requested more explanation of exactly what is meant in the Bill by “biodiversity” and what is going to be demanded of improvements to biodiversity as we go through implementing what the Environment Bill is looking to do.

In short, I have enjoyed listening to the debate, but we are happy to retain the use of “biodiversity” in the wording of the Bill.
