Prof Louise Heathwaite CBE became the executive chair of the National Environment Research Council (NERC), the UK’s main agency for funding natural science research, in March 2024.
She was the chair of the Science Advisory Council of the UK’s Department for Environment, Food and Rural Affairs (Defra) and has previously served as chief scientific adviser to the Scottish Government for Rural Affairs, Food and Environment. She is a leading hydrochemist.
- On realising human’s environmental impact: “When the ozone hole was being discussed. So I knew from a long, long time ago that we were doing damage.”
- On funding climate research: “You can’t look at climate research just as climate research. It’s a nexus. It’s thinking about climate change, the implications for biodiversity loss and other changes like pollution.”
- On funding solar geoengineering: “A few years ago, I think this council and many others would not have gone into solar geoengineering in any sense. We’re getting closer and closer to 2050. That starts you looking for more extreme routes.”
- On Brexit’s impact on UK research: “I think that led to some breakage of communication and links with people working in Europe particularly.”
- On reaching net-zero in the farming sector: “So far, that vision hasn’t been much beyond ‘we’re going to plant trees everywhere, and cows are bad’.”
- On transforming land-use in the UK: “We do need it, but it’s hard to see who’s going to really have the oversight.”
- On lack of public attention on biodiversity loss compared to climate change: “I think pollution and biodiversity loss are lagging behind as it’s much more complex to understand that system.”
Carbon Brief: You have a long standing career as a hydrologist and a pollution expert, when did you first become aware that humans were having a large impact on the natural world through pollution and agriculture?
Prof Louise Heathwaite: Before I went to university – well before I went to university. At school I studied maths, economics and geography and put it together in that sort of sense. Then I went on to do an environmental science degree at the University of East Anglia. At that point, there were only two places you could do environmental science, UEA or Lancaster. Lancaster was far too close to home for me [Heathwaite is from Leeds]. UEA were doing some really cutting edge science. That’s when the ozone hole was just being discussed. So I knew from a long, long time ago that we were doing damage. So it’s been with me all that time. And that progression with working with the Natural Environment Research Council started at that point. I went from doing a degree to doing a PhD at Bristol and that was funded by NERC.
CB: What was your PhD in?
LH: I was looking at peatlands, wetland hydrology and hydrochemistry. I was looking at the impact of [peatland] drainage on water quality. The place I was working was the first SSSI [site of special scientific interest] ever declared in the country. It was a place called West Sedgemoor in the Somerset Levels. It was a real interesting challenge there, looking at the difference between what the [wildlife charity] RSPB wanted to do to protect that site versus the farming community, who wanted to actually farm that site, and how you get some sort of shared understanding. It was really fascinating. And underneath that there were some real chemistry questions to answer as to why the river was getting polluted and what the issues were. And it wasn’t anything to do with the farming community at all. It was to do with the geology of the site. Really interesting.
CB: This year, you became the executive chair of NERC. What are the key areas of climate research that NERC is looking to fund?
My perspective is you can’t look at climate research just as climate research. I think there are three parts to this, it’s a nexus. It’s thinking about climate change, the implications for biodiversity loss and other changes like pollution. So I always argue you’ve got to think of it through that three-way nexus. The direction of travel I’m trying to take NERC through in terms of our forward look is developing thinking that I’m starting to call “beyond carbon”. So when you talk to communities like the financial industry, what they’re looking for when they want to understand biodiversity loss is another metric, like carbon, that can tell them how to deal with the problems. [We need to] get to the realisation that, for biodiversity loss, there is no single metric. And a lot of what the climate change drivers are doing are causing feedback loops, which damage biodiversity, create other sorts of challenges, and how do we understand that? So there’s a whole load of work to do in that sort of space. So that’s one bit where climate change is a real driver. The other bit is around national security and health. Your floods, your droughts, risk for wildfires, risk for temperature and heat and what that does to people. That’s another area.
Then the third area you might think will be quite unusual for NERC, which is starting to look at what we’re calling “responsible innovation”. So NERC has just got a call out around solar radiation management. Now, a few years ago, I think this council and many others would not have gone into solar geoengineering in any sense. But the position we’re getting into now is we’re getting closer and closer to 2030 and to 2050 and trying to get to things like net-zero. That starts you looking for more extreme routes. I think it’s important that a research council tries to understand what the implications are of anybody following those extreme routes. I need to be clear, we’re not doing out-of-door experiments, it’s more around modelling and maybe some laboratory work to try and understand that. But if we don’t understand solar radiation management, or we don’t understand the sort of interventions you might do in the oceans, then we’re not going to be able to advise on the implications. And, with the Natural Environment Research Council, we’ve got everything at our fingertips, really, because we do deep ocean to upper atmosphere. We do pole to pole. We do air, land, water. And that captures the global capacity. And so actually addressing those climate change challenges sits right in our remit, at a very difficult time, really.
CB: How has NERC research funding been impacted by Brexit? Does NERC have all the resources it needs at the moment?
Brexit or everything else after Brexit? We’ve had Brexit, then we have Covid, and then we had Ukraine and inflation and all of those things. From a Brexit context, and this is a personal view, I think that led to some breakage of communication and links with people working in Europe particularly. Now we’re part of Horizon again [the EU’s €96bn research programme], I can see that coming back, which is absolutely fantastic, it’s really important. I think also within NERC, all of those issues that I just mentioned have also led us to perhaps start looking [at] more UK-wide, rather than global and international science. That’s something I want to change. That international science is absolutely critical, particularly as we’ve got many of our scientists working with the IPCC [Intergovernmental Panel on Climate Change] and IPBES [Intergovernmental Science-Policy Platform on Biodiversity and Ecosystem Services]. And we’ve got the new UN Environment Programme around pollution and waste. So those three areas I mentioned before, we’ve now got intergovernmental panels which are actually looking at them. I think of our opportunity as to how we bring them together and think about it as a system.
CB: You recently stood down as the chair of the Science Advisory Council for Defra. What did it entail, how often were you briefing ministers and what kind of information were you sharing with them?
LH: So this was the highest level advisory committee within Defra, but part of our role was very particularly to help support and advise the chief scientific adviser [CSA], so that they were getting the best sort of advice. So the way that that worked was to basically take challenges from across Defra and [answer questions such as] are we doing this right? What’s your advice? How could we do this sort of thing? And get that [answered] by a wide range of people on the committee. [This was] to actually ensure two things: that the right sort of questions were being asked of the science and the right sort of evidence was being gathered, and that evidence was being used effectively. So the route was really to make sure that the CSA had a group of “critical friends”, in a sense, but also was [well] informed. Briefing ministers was the CSA’s job. Acting as a science advisory committee [and] actually making sure that the CSA and others in Defra were actually being coherent in their messages around the science – it was fascinating. But I’d been on Defra’s Science Advisory Council before, so that was really exciting. I’ve been a chief scientific adviser in the Scottish Government for Rural Affairs, food and environment before, so that fitted really well with that role. But it’s an important entity providing that sort of independent advice, that critical friend bit, is always important.
CB: Farming and land use have been a weak spot in UK climate plans, and now agriculture is a bigger emitter than power plants, for example. What do you think is needed to help the farming sector get to net-zero?
LH: I guess let’s start with the end point, getting to net-zero by 2050. It’s going to be a challenge to ever get to [actual] zero [emissions]. And what does getting to the “net” in net-zero mean? We need to have that national security of still being able to turn the lights on. I think that’s important. By setting targets and target dates, this is the bit I mentioned about geoengineering, it tends to get more and more desperate measures because you’ve got a target. I tend to think of it more as a transition. How do we transition, both in terms of behaviours, but also in terms of the science and the interventions we can put in to actually get to those sorts of places? So that seems to me to be really, really important and how we actually capture that moving forward is critical.
CB: So how do we transition the farming sector?
LH: That is always going to be a challenge because you’ve got two things. One, I think we need to look at farming and the farming community and landowners as being part of the solution, not the problem. Think of them as custodians of land and of the environment. Therefore, you start having a different conversation, which isn’t, “this is wrong, having cows and sheep is wrong”. But: “How do we actually get to a better place where we can have a shared understanding of what the environment’s about? What alternative livelihoods do people have?” Even down to evaluating whether we pay the right sort of amount for the meat we want to eat. So if people were prepared to pay more but eat less of it, that might actually change the economics of how farming might work. But none of that works if you go to the supermarket and buy something that’s been shipped in from some other country, either. So I think it’s a conversation, a shared conversation, about what the vision is for the future. And I think, so far, that vision hasn’t been much beyond “we’re going to plant trees everywhere, and cows are bad”. You’ve got to turn it into “we’ve got a fabulous landscape, we’ve got a very dense population, we want to do all these other things with our land, how can we actually have a conversation to get us to the right place?” And that’s not going to be easy, but what I’m seeing is now much more cross-government thinking about how to get there.
If you actually mapped out all the policies that we want to achieve from our land, we haven’t got enough area, nowhere near enough area, to actually achieve them. So we’ve got to think about the nature of the interventions and what we achieve. It’s a really exciting space. From my perspective, coming from where I came from as a scientist, understanding how those changes might impact on other parts of the system. So like the freshwater environment, which is always the bucket in which all the problems end, and then we pass that on to the marine environment, and we pass it up to the atmospheric environment, how can we actually get a more sustainable solution there? So it’s an opportunity, But if you turn it into a problem, all you do is back people into a corner.
CB: The new Labour government has come in, and it has a lot on its in-tray when it comes to food, land in nature, including a land-use framework and its international nature pledge under the UN biodiversity convention. Which of these documents would you like to see being published soon, and what sort of details do you think will be critical for those documents?
LH: Big question, massive question. I’ll probably answer this a bit tangentially because it’s really a matter of how you can achieve what you can achieve. This government has got a very strong focus on delivery for people quickly. And there are some quite exciting and quite interesting projects around clean energy by 2030, as an example. So what does that mean for things like land use that we’ve just been talking about, biodiversity and all of those things? Is it a really good pledge, but the ones around the land-use strategy are really, really challenging. Because, say, clean energy for 2030, if we can make that work, we’ll need to make sure we get the transition mechanisms in place to move energy around from generation points to to where it actually needs to be delivered. If we can do that for energy, we can probably do that for land. So we do need it, but it’s hard to see who’s going to really have the oversight. And everybody wants a piece of this pie. But all the things that this new government is wanting can’t be achieved without some joined-up thinking. So I put that quite high.
I also think making clear our commitment to work in the international space [is important]. My council, the National Environmental Research Council, is the one that thinks at long timescales, large scales, global. So actually having that international presence and keeping our science cutting edge and curiosity driven is just so important in that sort of space. So I’d be articulating that through the new government that the research and innovation part is really, really critical, because that’s where you’ve actually got that curiosity driving new thinking, but you’ve also got the innovation which takes that new thinking and now converts it into something useful. Some of it’s shovel-ready now, but actually, some of it’s going to take time to actually get us there.
CB: So, finally, we touched on this before, but the issues of pollution and biodiversity loss tend to receive less attention at a national and international level than climate change. Why do you think that is and how can that be addressed?
LH: I think it’s only that climate change has been thought of as being doable – because it’s carbon, and we’ve got that single metric – and therefore business and industry can buy into that and they can think about how to build it into their business models. The reason I think pollution and biodiversity loss are lagging behind is it’s much more complex to understand that system and we’re only getting together now with the science to actually help us do that and develop those metrics. But there is no single metric to say we can understand biodiversity loss. It’s going to take some more systematic thinking. And one of the really good things I think about where NERC is now placed within UKRI [UK Research and Innovation, a government department] is that we’ve got that cross-research council thinking, which allows you to pull from all the various disciplines to get a solution.

‘Step up and lead’: All eyes on Australia as it takes the reins of UN COP31 climate negotiations
ANTALYA, Türkiye, Saturday 7 November 2026 — As leaders and delegates gather for the UN COP31 climate summit, Greenpeace Australia Pacific is calling on the Australian government in its role as President of Negotiations to ensure the just transition away from fossil fuels is central to negotiations, rigorously defend the 1.5°C temperature goal, and significantly scale up climate finance commitments.
This year’s climate talks take place amidst a deepening global energy shock, and grim reports that the world will barrel past the 1.5°C temperature goal. They also follow a deadly summer of extreme weather disasters that swept the northern hemisphere, with fears that a severe El Niño will see similar dangerous impacts in Australia.
But recent election wins by progressive candidates in the United States and Brazil are set to breathe energy and optimism into the negotiations as people around the world, bearing the brunt of soaring cost of living and climate disasters, shun regressive and divisive politics.
Speaking from Antalya, Dr Simon Bradshaw, COP31 Lead at Greenpeace Australia Pacific, said: “The world is in a moment of flux. We know it is in moments of huge upheaval that era-defining progress can happen — but only when countries step up and lead.
“As Australia takes control of COP31 Negotiations, we have an opportunity and responsibility to shepherd global climate cooperation through this moment of interlocking crises. That means backing Pacific leadership and priorities, and leading by example at home to end fossil fuels and deliver new, multi-year climate finance commitments.
“As a major coal and gas exporter, Australia plays an outsized role in fuelling the climate crisis, and has approved 38 new, extended and expanded fossil fuel projects since first elected in 2022. More than half the world’s coal export project pipeline is in Australia, and the Albanese Government is poised to make decisions on massive new gas projects. Australia must reckon with this reality.
“Domestically, we have made significant strides on ramping up renewables and the global ‘35 by 35’ electrification goal is welcome and necessary. But electrification must end fossil fuel dependence, not be an end in itself — its ultimate success depends on ensuring electricity comes from renewable sources that displace fossil fuels and align with a 1.5°C pathway.
“In Türkiye, the Australian government can rise to the occasion and show what true climate leadership looks like, but we can not move the world towards a clean energy future while expanding the industry we need to leave behind.”
Speaking from Antalya, Shiva Gounden, Head of Pacific at Greenpeace Australia Pacific, said: “As leaders meet in Türkiye amidst warnings that we will pass the 1.5°C threshold, the stakes have never been higher. Every heatwave, every flood, every storm is being unleashed on communities with the deadly force of accumulated emissions and gives a warning of what is to come.
“In Antalya, the COP31 Presidency must respond to the accelerating climate crisis and defend the 1.5°C goal based on the law and the science. 1.5°C is a non-negotiable survival line for Pacific communities and climate-vulnerable nations facing rising seas, extreme weather disasters, food insecurity and soaring economic costs. It is a fundamental component of the Paris Agreement and enshrined as a binding legal benchmark by the world’s highest court, the International Court of Justice.
“Australia must arrive at COP31 with more than meaningless speeches. The Pacific and the world need concrete dates, credible plans to deliver roadmaps away from fossil fuels built on the best available science, and a commitment to put people, energy security and the planet ahead of fossil fuel interests.
“We need real action to advance multilateral climate cooperation, ensure the just transition away from fossil fuels is high on the agenda, and back longstanding Pacific priorities — including keeping 1.5°C alive and significantly scaling-up climate finance.”

‘Step up and lead’: All eyes on Australia as it takes the reins of UN COP31 climate negotiations
As an extreme El Niño breaks marine temperature records, COP31 is set to boost the profile of the ocean’s role in solving climate change, but finance and clear conservation measures will be needed for it to move the needle, experts said.
The Turkish presidency has announced plans for an Antalya Ocean Declaration that recognises the centrality of the global ocean – the world’s largest carbon sink – in regulating the climate and minimising the now unavoidable overshoot of global temperatures above 1.5C over pre-industrial levels.
Meanwhile, as part of the formal UN negotiations, Australia has announced plans to land a cover decision in Antalya, which, according to veteran former US negotiator Sue Biniaz, would be the only section of the formal negotiations where the role of oceans could be included.
She added that an outcome at COP31 seems likely, given the initiative from both presidencies and a push from over 100 countries – including Brazil, the EU and the African Group of countries – calling for the UN negotiations to deliver a plan for implementing ocean measures.
Governments will arrive in Antalya with a “super El Niño” adding stress to marine ecosystems and expected to continue to intensify until December 2026, with parts of the Pacific averaging almost 30C (86F) – over 3C more than normal – in October, according to monthly EU sea temperature data.

Needs for ocean conservation and funding
While elevating the ocean agenda is “critical”, it must lead to funding for ocean conservation and a clear plan for reaching the global target – set at UN biodiversity talks in 2022 – of protecting 30% of the global ocean by 2030, said Pradeep Singh, senior ocean governance expert at Oceano Azul Foundation.
The ocean is precisely where governments are farthest off track from meeting this target – informally known as the 30×30 goal. Even if countries meet all their nature conservation plans, only about 12% of the global ocean would be protected, the UN says.
“Acknowledgment of marine protected areas and the 30×30 target as climate infrastructures will certainly boost efforts and funding for science and management,” Singh told Climate Home News.
Shamini Selvaratnam, director of international climate and clean energy at Ocean Conservancy, said an ocean commitment that makes a difference in coastal communities “takes funding, local capacity and support that countries can actually access”.
An analysis by climate think tank Zero Carbon Analytics shows that investment in the blue economy – through activities like sustainable fisheries or cleaner shipping – is only at about 2% of the needs, which are estimated at $550 billion per year.
Following-through on commitments
Selvaratnam added that countries must also establish mechanisms to follow through on these measures, which currently only exists in the form of a non-binding dialogue that is not expected to produce any negotiated agreements.
She said that countries at COP31 must find ways for their ocean commitments to inform the next global stocktake, the UN’s five-yearly review of progress on climate action. Some countries – including African countries, Latin American nations, small island states and the European Union – have backed a process that culminates in the next global stocktake.
At climate negotiations, countries are not mandated to include ocean conservation measures in their climate plans. But a group of countries led by France and Brazil is pushing them to do so voluntarily through an initiative called Blue NDC Challenge. Seventeen countries have joined the initiative so far.
In its list of COP31 priorities, the EU has called for the “critical role” of oceans to be recognised, but falls short of calling for any specific actions to feature marine action more prominently in climate plans.
As part of their demands, ocean campaign groups have called for the establishment of an “Antalya Ocean Compact”, a platform where countries can coordinate efforts across different environmental treaties, including the UN climate, biodiversity and high seas negotiations.
Ultimately, Selvaratnam said a strong deal “must accelerate emissions cuts, clean energy, and a transition away from fossil fuels, including offshore oil and gas”.
Ilana Seid, chair of the AOSIS group of small island states and permanent representative of Palau to the UN, said during a press briefing last week that “meaningful progress” on emissions reduction is “the best way” to alleviate stress on the ocean.
