COP30: Food System Transformation

Debate between Monica Harding and Barry Gardiner

Tuesday 14th October 2025 Westminster Hall

[Monica Harding (Esher and Walton) (LD)]

It is an honour to serve under your chairship, Mrs Harris. I thank my hon. Friend the Member for South Cambridgeshire (Pippa Heylings) for bringing this critical debate to the House. Next month, the eyes of the world will turn to the Amazon and Brazil for the COP30 climate conference. The choices made there will define the world that our children and grandchildren inhabit. That is why it is imperative that the conference delivers real, sustainable progress.

Achieving that, however, requires much more ambition from the UK. It requires proper climate financing, a faster roll-out of clean energy and greater leadership on the world stage. So I ask the Minister: will the Prime Minister attend COP in Brazil? Just a few years ago, the Prime Minister rightly accused his predecessor, the right hon. Member for Richmond and Northallerton (Rishi Sunak), of a failure of leadership for not attending the COP summit—so will the Prime Minister attend?

As Liberal Democrats, we have long championed international climate diplomacy. We have championed the Paris agreement, a landmark and historic agreement that remains the central framework for global climate co-operation. It is deeply disappointing that the United States is once again withdrawing from it under President Trump, joining the likes of Iran, Libya and Yemen. Climate change is not some distant, far-off risk. We already feel its effects here, with the hottest summer and the second-worst harvest on record, higher food prices, soaring insurance premiums and increasing water bills.

The effects are being acutely felt throughout the world. Zero hunger is the second of the sustainable development goals—the world’s blueprint for a better world. However, the SDGs have been casualties of the Trump Administration. According to the latest UN development reports, we are nowhere near that target. Over the last five years, climate change has contributed to driving 150 million more people into malnutrition, a reminder that this crisis strikes hardest at the world’s poorest. That is why the Liberal Democrats would champion reform of the international finance system, easing the debt burden and unlocking green investment in low-income countries. We would back the UN loss and damage fund to ensure a just transition for those who are suffering the consequences of a crisis they did not cause.

Climate change is not just an environmental challenge; it is a threat multiplier, fuelling displacement, conflict, hunger and disease from the Sahel to the Pacific. As an example, following the 2022 floods in Pakistan, the country’s malaria burden quadrupled. This Government have cut international development spending to 0.3% of GNI, the lowest level this century. But they have none the less claimed that international climate finance will remain a priority. Can the Minister confirm not only that the target of spending £11.6 billion on international climate finance between 2021 and 2025 will be met, but that the Government will make a bold new commitment to lead on climate finance and use development finance institutions to accelerate decarbonisation in low-income countries?

[Barry Gardiner]

The hon. Lady will recollect that, of that £11.6 billion, £3 billion was ringfenced for conservation. Does she agree that it is important that we do not lose that element of ICF?

[Monica Harding]

The hon. Member is absolutely right, and I ask the Minister to guarantee that that is ringfenced. What we do in Britain sends signals to the world about whether we are serious or simply posturing. Renewables are the greatest economic growth opportunity of our time, bringing jobs, investment and lower bills to the nation. However, in a crass, short-sighted attempt to imitate President Trump, the Conservatives and Reform have turned against renewables. Their attacks on green energy will scare off investors, destroy jobs and relegate Britain to the sidelines of the industries that will define our future. Both parties have abandoned our net zero target, a reckless move that will shatter our credibility on the world stage.

The Liberal Democrats believe that there is no trade-off between climate sustainability and food security. They can both be achieved if the right framework is put in place. The UK food security report warns that climate change, water insecurity and nature loss threaten global food supplies. Liberal Democrats would champion investment in sustainable agriculture, helping farmers in low-income countries build resilience to droughts, floods and changing weather. We would work through international institutions to build a fair and resilient global food system.

As my hon. Friend the Member for South Cambridgeshire laid out, will the Minister commit to signing the COP30 declaration on food systems, when it comes, and to adopting the priorities of deforestation-free supply chains, nature-positive farming and support for family farms?
