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.”

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.

Back to top

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.

Back to top

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.

IEA: Slow transition away from fossil fuels would cost over a million energy sector jobs

Published

on

A slower shift to clean energy could leave the world with 1.3 million fewer energy sector jobs by 2035 compared with a scenario in which governments fully implement their green policies, the International Energy Agency (IEA) has found.

In its annual World Energy Employment report, the Paris-based watchdog said on Friday that the Current Policies Scenario (CPS), which it reintroduced under pressure from the Trump administration, has “more muted” employment growth than the Stated Policies Scenario.

The CPS sees oil and gas demand continuing to rise until at least 2050 – a scenario that the IEA described as “cautious” and “anchored in enacted laws and measures” and was widely criticised by clean energy experts.

A fast energy transition would spur investment in construction, creating more jobs across the sector. New roles for electricians, building insulators, solar panel and energy-efficient lightbulb installers, and transition mineral miners would more than offset job losses in coal mines, power plants and oil and gas fields, the report found.

    Anabella Rosemberg, Just Transition lead at Climate Action Network International, lamented that the clean energy sector is “being undermined at a time when employment creation is of utmost priority”.

    “Climate ambition and decent job creation must go hand in hand – but as the recent conversations at COP30 showed, there is a need for both the right targets and just transition strategies to make it happen,” she added.

    A more ambitious Net Zero Emissions scenario, aligned with the Paris Agreement goal of limiting global warming to 1.5C, would see roughly ten million more energy jobs created than under the CPS, report author Daniel Wetzel told Climate Home News at a press conference.

    Bottleneck warnings

    The IEA warned that governments must act to train workers for these roles or risk facing shortages of electricians, welders, and grid specialists – a gap that could slow the energy transition and drive up wages and energy costs.

    IEA head Fatih Birol highlighted a particular shortage of qualified workers in the nuclear industry, warning that the problem could worsen as the sector’s workforce continues to age. “I hear nuclear is making a comeback, but the interest in the nuclear sector for the jobs is rather weak,” he said.

    Laura Cozzi, IEA’s Director of Sustainability, Technology and Outlooks, warned of a shortage of skilled workers in electricity grids. “That is one of the key ingredients why we are not seeing grids ramp up as [they] should,” she said. Over 60 governments pledged at COP29 to improve and expand their grids to enable clean electricity to flow to where it is needed.

      Bert De Wel, Global Coordinator for Climate Policy at the International Trade Union Confederation, celebrated that the energy transition is creating jobs but added that they should be good jobs with decent pay, conditions and union rights. Decent work would attract skilled workers, he added.

      The report found that wages in the oil and gas industry have generally risen faster over the past year than in the solar – and especially the wind – sectors. It noted that the oil and gas industry has a “historical tendency to offer highly competitive wages to attract and retain top talent”.

      At the COP30 climate summit, governments agreed to set up the Belém Action Mechanism to try and make the energy transition fairer to groups such as workers in the energy industry. It will give trade unions a formal role in shaping just transition policies, for what the ITUC says is the first time.

      ITUC General Secretary Luc Triangle called it a “decisive win for the union movement and working people across the world, in all sectors but especially those in transition industries.”

      DeBriefed 5 December: Deadly Asia floods; Adaptation finance target examined; Global south IPCC scientists speak out

      Published

      on

      Welcome to Carbon Brief’s DeBriefed.
      An essential guide to the week’s key developments relating to climate change.

      This week

      Deadly floods in Asia

      MOUNTING DEVASTATION: The Associated Press reported that the death toll from catastrophic floods in south-east Asia had reached 1,500, with Indonesia, Sri Lanka and Thailand most affected and hundreds still missing. The newswire said “thousands” more face “severe” food and clean-water shortages. Heavy rains and thunderstorms are expected this weekend, it added, with “saturated soil and swollen rivers leaving communities on edge”. Earlier in the week, Bloomberg said the floods had caused “at least $20bn in losses”.

      CLIMATE CHANGE LINKS: A number of outlets have investigated the links between the floods and human-caused climate change. Agence France-Presse explained that climate change was “producing more intense rain events because a warmer atmosphere holds more moisture and warmer oceans can turbocharge storms”. Meanwhile, environmental groups told the Associated Press the situation had been exacerbated by “decades of deforestation”, which had “stripped away natural defenses that once absorbed rainfall and stabilised soil”.

      ‘NEW NORMAL’: The Associated Press quoted Malaysian researcher Dr Jemilah Mahmood saying: “South-east Asia should brace for a likely continuation and potential worsening of extreme weather in 2026 and for many years.” Al Jazeera reported that the International Federation of Red Cross and Red Crescent Societies had called for “stronger legal and policy frameworks to protect people in disasters”. The organisation’s Asia-Pacific director said the floods were a “stark reminder that climate-driven disasters are becoming the new normal”, the outlet said.

      Around the world

      • REVOKED: The UK and Netherlands withdrew $2.2bn of financial backing from a controversial liquified natural gas (LNG) project in Mozambique, Reuters reported. The Guardian noted that TotalEnergies’ “giant” project stood accused of “fuelling the climate crisis and deadly terror attacks”.
      • REVERSED: US president Donald Trump announced plans to “significantly weaken” Biden-era fuel efficiency requirements for cars, the New York Times said.
      • RESTRICTED: EU leaders agreed to ban the import of Russian gas from autumn 2027, the Financial Times reported. Meanwhile, Reuters said it is “likely” the European Commission will delay announcing a plan on auto sector climate targets next week, following pressure to “weaken” a 2035 cut-off for combustion engines.
      • RETRACTED: An influential Nature study that looked at the economic consequences of climate change has been withdrawn after “criticism from peers”, according to Bloomberg. [The research came second in Carbon Brief’s ranking of the climate papers most covered by the media in 2024.]
      • REBUKED: The federal government of Canada faced a backlash over an oil pipeline deal struck last week with the province of Alberta. CBC News noted that ​​First Nations chiefs voted “unanimously” to demand the withdrawal of the deal and Canada’s National Observer quoted author Naomi Klein as saying that the prime minister was “completely trashing Canada’s climate commitments”.
      • RESCHEDULED: The Indonesian government has cancelled plans to close a coal plant seven years early, Bloomberg reported. Meanwhile, Bloomberg separately reported that India is mulling an “unprecedented increase” in coal-power capacity that could see plants built “until at least 2047”.

      $518 billion a year

      The projected coastal flood damages for the Asia-Pacific region by 2100 if current policies continue, according to a Scientific Reports study covered this week by Carbon Brief.

      Captured

      A new target for developed nations to triple adaptation finance by 2035, agreed at the COP30 climate summit, would not cover more than a third of developing countries’ estimated needs, Carbon Brief analysis showed. The chart above compares a straight line to meeting the adaptation finance target (blue), alongside an estimate of countries’ adaptation needs (grey), which was calculated using figures from the latest UN Environmental Programme adaptation gap report, based on countries’ UN climate plans (called “nationally determined contributions” or NDCs) and national adaptation plans (NAPs).

      Inclusivity at the IPCC

      This week, Carbon Brief speaks to an IPCC lead author researching ways to improve the experience of global south scientists taking part in producing the UN climate body’s assessments.

      Hundreds of climate scientists from around the world met in Paris this week to start work on the Intergovernmental Panel on Climate Change’s (IPCC’s) newest set of climate reports.

      The IPCC is the UN body responsible for producing the world’s most authoritative climate science reports. Hundreds of scientists from across the globe contribute to each “assessment cycle”, which sees researchers aim to condense all published climate science over several years into three “working group” reports.

      The reports inform the decisions of governments – including at UN climate talks – as well as the public understanding of climate change.

      The experts gathering in Paris are the most diverse group ever convened by the IPCC.

      Earlier this year, Carbon Brief analysis found that – for the first time in an IPCC cycle – citizens of the global south make up 50% of authors of the three working group reports. The IPCC has celebrated this milestone, with IPCC chair Prof Jim Skea touting the seventh assessment report’s (AR7’s) “increased diversity” in August.

      But some IPCC scientists have cautioned that the growing involvement of global south scientists does not translate into an inclusive process.

      “What happens behind closed doors in these meeting rooms doesn’t necessarily mirror what the diversity numbers say,” Dr Shobha Maharaj, a Trinidadian climate scientist who is a coordinating lead author for working group two (WG2) of AR7, told Carbon Brief.

      Global south perspective

      Motivated by conversations with colleagues and her own “uncomfortable” experience working on the small-islands chapter of the sixth assessment cycle (AR6) WG2 report, Maharaj – an adjunct professor at the University of Fiji – reached out to dozens of fellow contributors to understand their experience.

      The exercise, she said, revealed a “dominance of thinking and opinions from global north scientists, whereas the global south scientists – the scientists who were people of colour – were generally suppressed”.

      The perspectives of scientists who took part in the survey and future recommendations for the IPCC are set out in a peer-reviewed essay – co-authored by 20 researchers – slated for publication in the journal PLOS Climate. (Maharaj also presented the findings to the IPCC in September.)

      The draft version of the essay notes that global south scientists working on WG2 in AR6 said they confronted a number of diversity, equity and inclusion (DEI) issues, including “skewed” author selection, “unequal” power dynamics and a “lack of respect and trust”. The researchers also pointed to logistical constraints faced by global south authors, such as visa issues and limited access to journals.

      The anonymous quotations from more than 30 scientists included in the essay, Maharaj said, are “clear data points” that she believes can advance a discussion about how to make academia more inclusive.

      “The literature is full of the problems that people of colour or global south authors have in academia, but what you don’t find very often is quotations – especially from climate scientists,” she said. “We tend to be quite a conservative bunch.”

      Road to ‘improvement’

      Among the recommendations set out in the essay are for DEI training, the appointment of a “diversity and inclusion ombudsman” and for updated codes of conduct.

      Marharaj said that these “tactical measures” need to occur alongside “transformative approaches” that help “address value systems, dismantle power structures [and] change the rules of participation”.

      With drafting of the AR7 reports now underway, Maharaj said she is “hopeful” the new cycle can be an improvement on the last, pointing to a number of “welcome” steps from the IPCC.

      This includes holding the first-ever expert meeting on DEI this autumn, new mechanisms where authors can flag concerns and the recruitment of a “science and capacity officer” to support WG2 authors.

      The hope, Maharaj explained, is to enhance – not undermine – climate science.

      “The idea here was to move forward and to improve the IPCC, rather than attack it,” she said. “Because we all love the science – and we really value what the IPCC brings to the world.”

      Watch, read, listen

      BROKEN PROMISES: Climate Home News spoke to communities in Nigeria let down by the government’s failure to clean up oil spills by foreign companies.

      ‘WHEN A ROAD GOES WRONG’: Inside Climate News looked at how a new road from Brazil’s western Amazon to Peru has become a “conduit for rampant deforestation and illegal gold mining”.

      SHADOWY COURTS: In the Guardian, George Monbiot lamented the rise of investor-state dispute settlements, which he described as “undemocratic offshore tribunals” that are already having a “chilling effect” on countries’ climate ambitions.
