COP30: Food System Transformation

Pippa Heylings Excerpts

Tuesday 14th October 2025 Westminster Hall

[Pippa Heylings (South Cambridgeshire) (LD)]

I beg to move,

That this House has considered COP30 and global food system transformation.

It is a pleasure to serve under your chairship, Mrs Harris. I appreciate the chance to have this debate, which is of critical importance, both globally and in our country, where the hottest summer since records began is pushing our farmers to the brink. The harvest of 2025 was the second worst harvest on record, according to the Department for Environment, Food and Rural Affairs. That comes on the back of over £1 billion of lost income for our farmers, following the extremely wet winter last year. All of that threatens our food security and pushes up food prices.

[Sarah Dyke (Glastonbury and Somerton) (LD)]

I thank my hon. Friend for securing this really important debate. She is absolutely right that we must support our farmers on food security and farm sustainability, but poor returns are threatening their viability right now. The dairy industry has contracted by 6% in the past year, and prices have dropped significantly; it was announced that they would go down by almost 20% in November. Some farms are going to be closing their gates for the very last time. Does my hon. Friend agree that to secure a fair deal for our farmers, the Agricultural Supply Chain Adjudicator and the Groceries Code Adjudicator must be combined and given real teeth to enforce properly?

[Pippa Heylings]

I thank my hon. Friend for that, and I applaud her constant advocacy in Parliament on behalf of farmers.

The second part of the debate is about the conference of the parties and how we can bring about legally binding obligations that translate into exactly the kind of measures my hon. Friend talked about. In just a few weeks, world leaders will come together at the global climate summit, COP30, which will be held in Belém, Brazil, in close proximity to the Amazon rainforest. It is being held there deliberately to symbolise the Amazon rainforest’s critical role in global climate stability.

In the lead-up to COP30, I hope this debate today will allow us to consider why this summit is expected to finally be billed as the nature, food and climate COP, putting food systems at the heart of the climate agenda for the first time, and rightly so, because the way we grow, produce and consume food is one of the biggest drivers of the climate and nature crises and one of the most powerful levers we have to solve them. At the same time, climate change is one of the most significant threats to our food production and national security.

Why does COP matter? We have come a long way since the Kyoto negotiations in 1997. That was the first time that countries around the world agreed global governance arrangements to address the shared challenge of global warming. At the time, we were hurtling towards a catastrophic 4°C or even 5°C world, so what a feat it was, unknown in any other sector or on any other issue, to create a framework agreement between 198 parties—197 countries or states and the European Union—to stabilise greenhouse gas concentrations at a level that could help to prevent dangerous human-induced disruption of the climate system. Through dialogue, negotiation and finance, the COP process has brought about legally binding agreements—the Kyoto protocol and then the Paris agreement in 2015—where we all agreed that we have a common and interdependent future, and that we need to do everything possible to keep global warming below 1.5°C.

The Amazon rainforest has been called the lungs of the planet for its ability to capture and store carbon. Yet, right now, the rainforest is gasping for breath as we perilously approach the tipping point where the Brazilian rainforest switches from being a huge sponge, store and carbon sink to being a source of carbon emissions, due to massive deforestation and degradation through land use change. That is why, now more than ever, we need to ratchet up our collective ambition.

I know that rainforest well, and I know what it means to the many indigenous and local communities that depend on it, having worked professionally on climate and nature negotiations for more than a decade in South America, in the countries that share the Amazon: Peru, Colombia, Ecuador, Bolivia and Brazil. I was part of the UK’s largest international climate policy programme in the region, and latterly I worked as the global team lead for the UK’s international £100 million climate and nature programme, the biodiverse landscapes fund. Since 2010, I have seen at first hand the internal workings, impacts, successes and failures of three relevant UN COP processes—the climate COP, the nature COP and the avoiding desertification COP—working alongside Governments and non-state actors such as businesses, scientists, local communities and local governments.

I know how long people have argued for food systems to be a central pillar of the climate framework. Our own independent Climate Change Committee, in its seventh carbon budget, highlighted the importance of agriculture and land use change in meeting our climate targets. I therefore want to make three points today. First, the transformation of food systems is essential for climate action, food security and nature restoration. Secondly, this transition must be just, supporting our farmers and animal welfare as we change how food is produced. Thirdly, the UK must show renewed leadership at COP30 by leading from the front, with the Prime Minister, and by committing to sign a new global declaration on food systems.

Why does food system transformation matter? The EAT-Lancet Commission announced that even if fossil fuels are phased out, the world will breach 1.5 °C because of emissions from food systems alone. Unsustainable food systems are driving deforestation, soil degradation, water pollution and marine biodiversity loss. Globally, agriculture and land use are responsible for almost 60% of biodiversity loss.

Exeter University research revealed this week that we have now reached the first catastrophic tipping point, with warm water coral reefs facing irreversible decline, threatening nature, food security and the livelihoods of hundreds of millions of people—a moment many of us hoped we would not reach. Closer to home, the Energy and Climate Intelligence Unit recently found that wheat lost to storms and drought over the past five years could have produced more than 4 billion loaves of bread—the equivalent of an entire year’s supply for the UK.

There has been a strong build-up to COP30 in Belém, which is expected to produce a declaration on food systems, building on discussions at the Bonn climate conference and the COP28 declaration on sustainable agriculture, resilient food systems and climate action, which the UK signed.

[Ann Davies (Caerfyrddin) (PC)]

COP30, as with past COPs, requires us to be more sustainable, and that includes food production, as the hon. Member said. In Caerfyrddin, we have a public farm producing vegetables for schools and residential homes, so public land is being used for public benefit. Why can all local authorities not follow suit, supported as we were by shared prosperity fund funding, and use public funds and public land for the public plate?

[Ann Davies]

No, it is not a speech. Thank you, Mrs Harris; I appreciate your guidance. Does the hon. Member agree with that sustainable and seasonal way of reducing food miles by using public land?

[Pippa Heylings]

I will perhaps come back to that a little later, but I agree completely about the importance of the SPF, as well as the sustainable farming incentive. In my constituency of South Cambridgeshire, we have public land—council land—working on regenerative agriculture with farmers, to provide the food we need. We need the stability and certainty of the SFI for our farmers.

The priorities it is anticipated will be negotiated at COP30 include deforestation-free supply chains, nature-positive farming, support for family farms and sustainable fisheries. This transformation has to be just, and that is as important here at home as it is globally. Farmers have always been on the frontline of climate change, as stewards of our countryside and producers of our food, and because they are struggling with the unavoidable impacts we now face. They must be at the heart of our solution.

The Liberal Democrats have been clear that the transition to sustainable farming cannot be done to farmers; it must be done with them. However, progress has been slow, and the uncertainty surrounding the sustainable farming incentive risks undermining the confidence and stability that farmers need if they are to continue to invest in regenerative agriculture, local food networks and diversified protein crops, as proposed by the National Farmers Union. Improving soil health, supporting pollinators and keeping farm businesses viable makes business sense too. As Martin Lines—the chief executive of the Nature Friendly Farming Network, who farms in Cambridgeshire—says, nature-friendly farming plays a “vital role” in building resilience to weather extremes. He says:

“Practices like improving soil health, using cover crops, and integrating habitats into fields are helping farmers stay productive while cutting back on inputs.”

We also call for a just transition in food and farming, as does World Animal Protection. At home, we must match words with action. The Liberal Democrats would accelerate the delivery of the long-promised land use framework, aligning food, farming and biodiversity policy. We would protect and strengthen the sustainable farming incentive and deliver it now. We would support a just transition for farmers and animals, reduce food waste across the supply chain and champion local, sustainable food production to boost rural economies and resilience.

[Andrew George (St Ives) (LD)]

Those points are all very welcome. Does my hon. Friend accept that global food systems already produce more than enough food to feed the world, but the problem is distribution and fair trade? As my hon. Friend the Member for Glastonbury and Somerton (Sarah Dyke) said earlier, the Groceries Code Adjudicator needs to be beefed up. We need to make sure that the supermarkets and the large retailers do not bully our primary producers to such an extent that they are wasteful in trade systems.

[Pippa Heylings]

Absolutely, and that is where the just transition must come in. We must make sure that this works at home. In fact, when we look at the amount of food being produced, we need to talk about nutritional security rather than food security.

Finally, the UK must lead at COP30. Belém will be a turning point. Negotiations are already under way for a new COP declaration on food systems.

[Mr Toby Perkins (Chesterfield) (Lab)]

I praise the hon. Lady for getting this really important debate going today. She is absolutely right, and I am confident that Britain will be among the most ambitious nations at COP30. However, will she, as I do, take a second to reflect on the fact that, thank God, we have a Government going there who believe in climate change and recognise that we need to get the rest of the world to be more ambitious, rather than a Conservative Government who would be going there to scrap the Climate Change Act 2008, or Reform turning up to say that climate change is entirely bogus?

[Pippa Heylings]

I could not agree more. I have worked internationally for 20 years, and I have seen that when Britain leads, other countries follow. Our Climate Change Act was the first in the world, and 60 countries immediately followed it. Other countries followed the independent Climate Change Committee. I have seen emerging economies work with their Governments, looking at how they do economic development and leapfrogging by learning from us. When Britain leads, others follow, and that is why I ask the Minister to make sure we confirm that the Prime Minister will be at COP30, to show that we continue to lead from the front.

I also ask the Minister to ensure that we sign up to the COP30 declaration on food systems and support all the work that has been done up until now to make sure that food systems are central to the climate change negotiations at Belém. I cannot emphasise more the impact, both here and across the world, of the U-turn—the turning of their back—of the Conservative Government, and Reform right now, on climate issues. I have worked alongside countries and communities ravaged by climate impacts that are waiting to see us take that leadership once again.

--- Later in debate ---

[Sir Alec Shelbrooke (Wetherby and Easingwold) (Con)]

It is a pleasure to serve under your chairmanship, Mrs Harris. I congratulate the hon. Member for South Cambridgeshire (Pippa Heylings) on securing this important debate.

For any of us with a farming constituency, there is no doubt what a difficult year this has been. Drought has led to lower yields, especially in arable farming—I have a mix of arable and animal farming in my constituency. When we talk about lower yields, we are not just talking about grain or the size of potatoes; we are talking about things like straw. The stalks have been much shorter this year, which will have a knock-on effect. And that is on the back of a very wet year last year, which created its own problems. There is no doubt that the farming industry is under enormous pressure. Sustainable farming is an important process that has been supported by many Governments across many countries in many different ways.

I will discuss climate change and what we need to do on renewables, but we must also recognise that, although there are appropriate places to put solar farms, it is not appropriate to put them on good-quality farming land. I am constantly fighting solar farms on farming land in the Vale of York in my constituency that is very productive but is now being sold off for solar farms. There has to be a balance between what we are trying to achieve in moving to renewable energy and what we have to achieve in sustainable farming.

The Liberal Democrats are quick to attack the Conservatives, but I remind them that it was Nick Clegg who stood at the Dispatch Box and cancelled a nuclear power station project, saying: “I am not willing to spend money on things that will not happen until 2022.”

But Ed Davey was the only person who—
