Emma Pinchbeck has been the chief executive of the UK’s Climate Change Committee (CCC) since November 2024.
The committee is a statutory body created under the Climate Change Act 2008 and is the official adviser to the UK government on climate change mitigation and adaptation.
In this role, the CCC delivers regular progress reports to parliament and advises the government on the level of future targets to cut the UK’s greenhouse gas emissions.
Previously, Pinchbeck was the chief executive of Energy UK, the trade association for the nation’s energy companies.
- On the UK’s net-zero progress: “[A] 50% reduction in emissions is pretty good going…the Climate Change Act has demonstrably worked.”
- On how the UK has cut emissions: “It’s not from exporting or offshoring emissions. It’s largely from displacing coal with renewables.”
- On what 2050 could look like: “I think it’s about keeping the stuff that we really love. And then making the stuff we don’t love better.”
- On the household impacts: “We’re pretty sure that a household with [clean technologies] in 2050 will be saving money, relative to a world where we stay dependent on fossil fuels.”
- On failing to reach net-zero: “Something that is in the memories of people in the 1970s as a one-off [heatwave] is going to be very common for our children.”
- On opposition threats to the Climate Change Act: “Whenever we’re doing our advice, we try and think about…how it reflects the priorities of different political parties.”
- On the UK’s high energy costs: “Over 80% of the rise over the last 10 years in energy bills has been about the price of gas.”
- On technology choices: “We’re an ‘all-of-the-above’ country, and I think that’s a good thing…the most resilient energy systems are those where you have a mix.”
- On the upcoming renewable auction: “We’re looking at that relative cost the whole time…I’m still extremely confident that a decarbonised energy system is cheaper than the counterfactual fossil-fuel one.”
- On decarbonising industry: “There should be a really vibrant future for our industrial sector…This positioning of ‘its industrialisation or its net-zero’ is wrong.”
- On the seventh carbon budget: “What exactly [the budget] looks like is down to parliamentarians and government [to] hash out.”
- On communicating on climate: “I think [the British are] natural environmentalists…I think we can talk to them more about why we’re doing this. I think we might have forgotten to do that, actually.”
- On climate misinformation: “Something that comes back in our social research is a desire for accurate information and particularly from policymakers.”
- On public communication campaigns: “The ones from the 1960s…[are] also quite punchy.”
- On talking to children about climate: “I’m aware that some of the loss sits with me, not with them. They will not have memories of how many butterflies there used to be.”
Listen to this interview:
Carbon Brief: Well, thanks very much for joining us today, Emma. I wanted to start with a kind of big question. The UK’s emissions are now a little more than 50% below 1990 levels and we’ve got about 25 years to get to the net-zero target by 2050. How would you say the UK is doing overall and why?
Emma Pinchbeck: Well, [a] 50% reduction in emissions is pretty good going. I think that’s the first thing to say, is that the Climate Change Act has demonstrably worked. And two important things; the pace of emissions doubled after the introduction of the Climate Change Act and also those emissions reductions have come from what I call “real change in the economy”.
So it’s not from changing patterns of, say, consumption emissions. It’s not from exporting or offshoring emissions. It’s largely from displacing coal with renewables – and also the magical thing is that it is coal to renewables. It’s not gone coal-gas-renewables either, which is what we thought it would do. So there’s a good story there in terms of the governance and how the Climate Change Act has worked.
I think also what’s important is that it was a technology-led process and there’s a lot of flexibility in the act. And so that in a coal-to-renewable shift, it’s probably not what we’d have all banked on when we were writing the Climate Change Act in 2008 or when they were writing the Climate Change Act. And so we think about that, if you look forward, you’re looking to replicate the successes of that in other bits of the economy now. We’ve done power, largely. I think it’s about heat in particular, but also transport. And then you start getting into trickier areas of the economy, where it is less about an energy transition and more into land use, things like offsets and removals.
But I think the overall story is similar, in that you set out a long-term objective, 10 years out. So, legislate the seventh carbon budget, and then try and invest in the technologies that you’ve got to deliver emissions reduction, try and make them as cheap as possible, try and make them as attractive as possible for people, and then do the tricky stuff.
And what we’ve said in the progress report is that the government needs to have more thinking on heat. We need to start planting trees, because it takes 25 years to grow a tree, and we need to start investing in the next wave of novel technologies. So the kind of surprises in the pathway, and there is a lot of focus on clean power, but it’s now about energy demand. That was a long answer.
CB: That’s fine, thank you. So you’ve already touched on this a little bit, but just projecting forward that 25 years to 2050, if you just imagine that we’re in the UK, we’ve hit the net-zero target. What does that look like? What does that mean for our communities, our environment, our consumer choices? Can you just paint a bit of a picture?
EP: So the first thing to say is, whatever picture I paint, I will inevitably be wrong. And that is, again, one of the joys about the Climate Change Act, is that we’re kind of thinking about outcomes, rather than necessarily wedding ourselves to single technology pathways.
That said, there are now some very clear winners, because over the last 10 years in energy, there’s been this huge shift towards electrical technologies on the demand side. The economics of stuff like batteries, solar PV [and] renewables are all trending down, and they look set over the next decade to beat their counterfactual fossil-fuel technology. So that will mean by about 2040, I think we’re saying three-quarters of cars on the road will be electric vehicles. We’re talking about a significant shift in electric vans also on the road. 40% of households with an electric heat pump and a shift to electrical heating.
We’re talking about more trees being planted – and native tree species and hedgerows largely rather than agroforestry. And what that then means in terms of the money, because these technologies on the energy side are more efficient, we’re pretty sure that a household with them in 2050 will be saving money relative to a world where we stay dependent on fossil fuels, and we’ve modelled that to be about £700 [in] savings.
But if you just want to talk about the physics, it’s because a heat pump is three to four times more efficient than a gas boiler. So you start getting savings back from the investment in these technologies by about 2040. At a whole economy level, you start saving money because you’re using a more efficient energy system, which both has a bills impact in the long run, but also does things like it changes our need to import as much gas, so it’s a more secure economy.
I realise they’re not tangible, but they’re important, particularly after the last 10 years. We’ve just gone through a gas crisis, and that has been really real for people. And then if you think about at community level, there’ll be different industries in different places, whether that’s carbon capture and storage or other low carbon fuels in the Humber, in the South Wales cluster, in parts of Scotland, some of that will be recycling existing fossil-fuel infrastructure, skills, jobs, some of it will be brand new industries, a “gigafactory”, for example.
And also in rural communities like the one I live in, you’ll see changes in how we’re managing land. And I think if the government gets its policies right, you should also see farming on a sustainable footing. And I mean, like, financially sustainable. So in some ways, it’s also about not changing, it’s about keeping things that we love, cherish, think about as part of our national heritage, and helping them survive a really big industrial transition.
So I get asked this question a lot, and sometimes I say to people that I think we’re quite keen to describe a world where everything is different, but actually I think it’s about keeping the stuff that we really love. And then making the stuff we don’t love better. And I wonder if that’s a more helpful pitch for people than everything is going to wildly change around you.
CB: Yeah. So again, you sort of touched on this, but let’s think about a world where we get to 2050, we haven’t reached our net-zero target in the UK, and perhaps more importantly, let’s say that the world has also failed to get close to net-zero emissions by mid-century. What does that world look like?
EP: We just did our adaptation progress report, which we do every two years, and in that, we talked about some of the impacts of climate change on the UK economy. We’re about to issue our statutory advice, which you do every five years in adaptation, and we will go into more detail on that.
But just to give you some high-level examples, it’s a world [where] the UK’s got more extremes. So our highest temperature in the summer has crossed 40C for the first time this year. That will become much more commonplace. We’ll see more of those kinds of hot summers, like we had in 2022 and just recently, more frequently. So every few years, rather than every 10 years. Something that is in the memories of people in the 1970s as a one-off, is going to be very common for our children.
If you think about winters, they will be warmer and wetter on average, so something like the last 18 months that we had before the heatwave, with all the rainfall.
What that then means [is that] the extremes [have] consequences for our infrastructure. So it becomes about how do you make sure that a hospital, a care home, a school, can stay open in a heatwave?
We know from 2022 that there are around 2,500 additional deaths because of the heat, largely in the vulnerable population. So we’ll need to think about that. Air conditioning for care homes or schools. We lose 1.7 school days on average to extreme heat. Again, what do you do about those settings?
If you think about rainfall and flooding, that has had a dramatic effect on UK agriculture already, things like the wheat crop, which is very sensitive to changes in temperatures or to rainfall. So maybe it’s our farmers diversifying, growing things like quinoa and other crops in different places, but also it will be about helping to mitigate what happens when we lose a harvest. So there’s that.
On infrastructure, it’s about making sure we’re building power plants, railways, new houses [on places other than] on floodplains, but also to be as flood resilient as we can possibly manage. We lose something like a quarter of railway kilometres already to extreme rainfall, which will become commonplace in 2050. A quarter of new homes, I think, are planned to be built in floodplains or will be affected by flooding by 2050.
So it’s really important to talk about the fact that when we’re thinking about mitigating emissions, it’s partly about reducing the amount of money that you have to spend on adapting the economy, but the impacts are already here, so we do also need to do adaptation.
CB: Great. Yeah. So obviously, the Conservative Party, the opposition Conservatives, have just pledged to repeal the Climate Change Act, should they be elected in 2029, and Reform’s also pledged to scrap the UK’s net-zero target. I’m just curious, have either of those parties been in touch with the committee, before or after or around those announcements?
EP: Well, not during the announcements and as you’d expect, we’re public servants at the Climate Change Committee and during party conferences and like the rest of the civil service, we’re not engaging [with] political announcements at all. So no, they haven’t, but nor would I expect them to and in a similar way, nor would I seek out that engagement.
What I can say is, whenever we’re doing our advice, we try and think about how it is meaningful, how it reflects the priorities of different political parties. We write out to every political party and offer to brief them. And we briefed the shadow secretary of state [Claire Coutinho] on the seventh carbon budget when that came out, and all of our analysis, and we will carry on having those relationships.
Fundamentally, the role of the committee is to advise governments, where advice is written for the government of the day, but it is also to report to parliament. We have no ability to hold ministers to account or overall policymakers, or [to] do anything of that kind. That’s not our job, but it is the job of parliament to hold government accountable. And so the mechanism is that we give parliament the best possible evidence and information in order for them to inform their own policies, whether or not they’re in opposition parties or in the government, and also to hold government to account on any legally agreed targets set by parliament, so we’ll keep doing that job.
CB: Great. Yeah, one of the big bug bears for both of those opposition parties is around the UK’s high cost of energy at the moment. Can you just kind of talk me through what’s going on? Why are our bills so high?
EP: Yes. How long have you got? So there’s a short-term, long-term framing for this, right? So over 80% of the rise over the last 10 years in energy bills has been about the price of gas. The UK is exposed to the price of gas on the international market, even when we’ve got relatively plentiful supplies in the UK, because we use a lot of gas in our heating as well as in our power generation. We’re quite a gassy energy system.
And because we are a relatively small producer, even with the North Sea, our ability to affect that price in any of the gas markets is limited. And so the only protection we have against price spikes or volatility or a rise in gas prices, really, is to reduce gas demand. And that’s one of the attractions of a more electrified power system, that’s what you’re effectively doing.
When I was in my last job and the energy crisis was on, one of the focuses of those of us who were being asked about what we could do about bills, what we could do about the economic exposure to gas, what we could do about energy security, was about electrification – nothing to do with climate at the time – but about trying to reduce gas demand. And that’s what other countries in Europe had been doing too in response to Russia’s invasion of Ukraine. So Poland has rolled out heat pumps, not because of climate, but because they’re trying to reduce their exposure to the gas price.
So that’s the wholesale cost of energy, and our exposure to gas is a huge part of the problem, and we shouldn’t lose sight of that. The other components of the bill are about policy costs and infrastructure costs that are levied from the bill or passed through to the bills by suppliers. So there is a component of the bill which is to do with the money it costs to reinforce our energy networks, and that’s increasing at the moment because we’re building out the power sector. That’s true. And there is also a bit of the bill which is about policy costs for things like renewables, but also social policy costs, things like the warm homes discount. And governments have always changed the levels of those policies. They designed them, but they also put them on the electricity bill rather than, say, on gas or in taxation; it was a choice to put them on bills. And so things like the cost of renewables and the renewables auctions, the costs of the early-stage renewables projects, the policy costs for energy efficiency, and so on. They’re all on that bit of the bill.
Now, those will change over time, and a lot of them are coming off in 2030 or being replaced by cheaper contracts that have been negotiated since. But there is a chunk of the bill at the moment, which are levy costs, and we have been saying to the government for some time now – including [to the] previous governments – that we think that those costs should be removed or redistributed. Now, how they do that is entirely up to them. We’re not policymakers, and we shouldn’t be prescribing issues of tax or distribution. But in having those policy costs in the electricity bill, people think electricity is much more expensive than it is, and so getting things like heat pumps onto the system, which would then help you with gas prices or our gas exposure, is harder because you’ve disproportionately impacted the electricity price. So it’s that, I don’t know if that was helpful.
I mean, at the supply end, there’s also the question of how much of the cost of generation that we’re then paying for that goes into that wholesale price? Are renewables cheaper or more expensive than a gas power station? Generally speaking, the economics of the energy transition should be cheaper overall than sticking with fossil fuels, in the long run, [so] what you’ve got to do is build the infrastructure. Though there’s a cost to that [and] it needs to be financed properly, the reason we think it should still be cheaper in the long run is once you’ve built the infrastructure, you don’t have the associated fuel costs for a renewables-led system. You have some different costs that we’re also paying for, to balance the system and to manage it. But even those work out to be cheaper than a system where you stay dependent on fossil fuels, we think.
So it is really complicated to explain to people and I suppose in a nutshell – I’d say, what, that took me like 10 minutes? And I can still see you being like, “well, that’s not a punchy answer”. And in that is the problem, because it’s in that lack of clarity, in the ability to be able to say, “well, it’s about the cost of decarbonisation”, and then we lose sight of the fact it’s actually, over the long term, been more about the cost of gas. I really need to have a better answer to that question.
CB: I mean, it’s interesting, maybe you can kind of slightly zoom out to, not just about the energy bills, but that whole cost of the transition. Because obviously, you’ve already mentioned some of this, but you’ve got investments, costs that we’re adding, building out the infrastructure, but also savings in terms of fossil fuel bills, and the way that that nets out, and the total that you come up, it’s quite easy to focus on one half of that or the other and not give the full picture.
EP: So you could do it in this way. You could think about the energy system as a whole. It’s the infrastructure in your system. And if you’re just talking about – let’s just talk about electricity, which is where a lot of the conversation is. To generate electricity, you need a power plant of some kind, which you have to build. Because even in a world where you were saying, “well, it’s not about building clean technology”, you have to build some power generation for things like artificial intelligence, the growing demand in the economy, you need [an] abundant energy supply. So you have to have a power plant, and [so] you have to build some new power plants. And then once you built your power plant, you need to move the power around. Even in a world where, say, you could generate the power, like with solar PV on people’s roofs and then use it in their homes. In the UK system, because we’ve got big nuclear, we’ve got cities, we’ve got factories, you need some big kit that generates big stuff, and then you have to move it around the system. So then you have to pay for pipes and/or wires to move things around. Your gas, if it’s going into a gas-fired power station, and then your wires to move the electricity that you generate.
And then once you’ve got all of that, you’re then paying the costs of managing the system. And there are costs involved in that, because you pay your power plants to provide services. But if they have to do unexpected things or provide a balance for another plant, or a power plant goes off, and you have to turn one on, there’s a cost for that that we all pay for in the market. And then at the end, we have these other policy costs, which are about redistributing money to pay for schemes that we think are important for the wider energy system, whether that’s energy efficiency or bill relief for fuel poverty. So those are some of your costs.
If you strip all of that back to the beginning, the reason that people like me say a renewables-led system is cheaper is [because] to build a brand new solar plant or wind plant is likely to be cheaper than the cost of building a gas CCGT, in most cases. So your cost of building the new plant is cheaper, and then you don’t have a fuel cost if you’ve built renewables, because you’re not buying in your gas to power it. You don’t need to build your gas pipeline, so there’s a saving there, but you do need to build more cables, because you need all kinds of renewable plants.
There’s then the cost of backing up your renewables with batteries or some decarbonised generation, maybe hydrogen. And then you’ve got your policy costs on the end. And so if you look at the balancing costs, you have to ask, “Well, does it cost more to balance out this wiggly renewable system and have to build another plant, then you’re saving on that fuel input?” And again, the answer there is, there are some costs of balancing the system, but it looks like they’re still cheaper than relying on the fossil fuel system.
And lastly, just very simply, generating electricity and then using it in more efficient products at the end is highly efficient. So in our analysis for the seventh carbon budget, we halve energy waste across the entire energy system, because the technologies on the other end of the system are more efficient, like electric vehicles and heat pumps. The technologies on this end of the system, like new renewables, are highly efficient, and we’re just moving stuff around on wires more efficiently. And that is also a saving, I think everyone out there knows that if you’re not wasting stuff, you’re saving money.
You’ve got to look at the whole system. It’s no good just to compare two different kinds of technology and think that that’s the answer. You’ve got to look at the whole system in the round, and then at the end, the bill in the round, and then make your choices.
Again, that’s a long answer, but because you’re talking about an energy system that underpins the entire economy, the mistake people often make is to look at a single data point on this end, on one day of the year, in one year. And it’s actually looking at the whole thing in the round. Is that better?

CB: Yes. So the UK’s net-zero transitions are obviously quite dependent on offshore wind, because of the fact that we’re an island nation, we’re at high latitude, we’ve got peak demand in winter and we don’t have great solar resources. People are looking at the energy transition globally and looking at how that picture’s changed.
You talked about falling technology costs; that’s been a big part of solar costs coming down massively. The cost of wind has come down a lot. And offshore wind’s a lot cheaper than we thought, but its costs have been going up in the last few years. And so some people I’ve seen [are] suggesting that perhaps the UK has made the wrong bet.
What do you think about that? And what are the other options that the UK could take, or is actually offshore wind still the right answer?
EP: Yeah. Well, actually, this sounds like a dodge, but it’s not. It’s important that we say this. It’s not the CCC’s job, actually, to dictate the technology mix. Like when we are doing our analysis, we model different technology pathways, and the reason for that is only that we have to demonstrate to parliamentarians that the number that we come up with for the carbon budget – so the percentage emissions reduction – is credible enough that they’re confident that the target could be met. How they then go about delivering that is for the government’s carbon budget delivery plan and for parliament.
And so the question for the CCC is, would we have a view on whether it should be offshore wind and onshore wind? No, beyond telling you what the relative costs of decarbonisation might be in 15 years time if you choose one or the other. And then the other thing is, sometimes governments make decisions about technologies for reasons that sit outside our remit. For example, it could be about [whether] you take an early punt on a technology because you want the jobs and the industrial benefits. You know, the reason that Scandinavians have so many wind companies and manufacture so many components is [that] they took an early bet on wind, after actually, the turbines were developed in the UK. There we go.
If you think about China and batteries, it’s similar. They took an early punt on electric vehicles and now have cheap electric vehicles. That’s an industrial play, almost more than it is the least cost way of delivering decarbonisation.
So it’s sort of respects the reason that the government might back particular technologies, and I think the government’s offshore wind targets – my memory of them at the time were also about Boris Johnson’s industrial vision for the UK, and I think they were bigger than what the CCC had recommended as well. So, there are always reasons for the government to back a technology which are not about decarbonisation. It’s a long way of saying, “Don’t ask me”.
But I think two other quick points. It is always a mix; the UK system is magnificent, because it is a mix of big and small and different technologies. We’re a pro-nuclear country, we’re a pro-renewables country, we’re an all-kinds-of-renewables country. We are also a country where we’re still going to have gas, and maybe potentially, one of the places that works out how to do things like carbon capture and hydrogen, because we’ve got a legacy of oil and gas industry here.
We’re an “all-of-the-above” country, and I think that’s a good thing, and the most resilient energy systems are those where you have a mix. And that would be something that I would say as an energy analyst, but it’s also the CCC’s approach when we’re looking at the energy system.
So if, for some reason, government chooses a pathway that is away from a particular technology, we’ll find another way of delivering it.
CB: So just more specifically on offshore wind, we’ve obviously got the next auction for CfD projects coming up, [with] results due in December or possibly a bit later. What are you expecting to see come out of that?
EP: You should go and ask me at my last job, where I would have probably had more of an idea of the commercials in the market, because that was literally the job – to understand that and live and breathe the auction. I think we would say, like every analyst is saying, [that] we’re expecting to see some of the supply chain crunch and the pressures on the industry in the prices.
But the beauty of competitive auctions is [that] they force competition. So I have been wrong on auction prices pretty much every time, apart from once, and I have learned not to speculate. There is always so much speculation in the run up to renewables auctions, and I think it’s unwise to try and work out what the prices are before we see them.
On the constraints and the sort of general economics, we modeled in a 25% uplift on our offshore wind costs relative to the kind of standard levelised cost assessment. And that’s because we’re assuming that there are supply chain pressures out to about 2030 and then we wind it down. So I think everyone can see that there have been labour shortages, there’s a higher cost of capital, there have been supply chain constraints because lots of other countries are doing offshore wind. There’s competition for the components and all of the rest.
The very last thing is, for my job, what’s relevant is [whether] the cost of other technologies go up? And a lot of those factors also apply for trying to build a new gas-fired power station or a new nuclear power station, because it’s about skilled labour, it’s about the cost of components, about the cost of financing large-scale infrastructure. And I think we’re looking at that relative cost the whole time, and in that I’m still extremely confident that a decarbonised energy system is cheaper than the counterfactual fossil fuel one.
The exact technology mix and the exact prices over the long run have very little impact on that final GDP number, first thing. And second thing, I think we’re in a pre-2030 world and we’ll see what happens with individual technologies in the long run. And very, very lastly, no one should speculate on auction prices. You’ll just look like an idiot when the final results come out.
CB: Great, yeah. So behind some of the political rhetoric that we’ve been seeing around the UK’s climate goals, the Climate Change Act, there are some genuine concerns around things like how to shepherd the UK’s industry through the transition.
It’s obviously quite a big change for the UK economy, but particularly for things like heavy industry. Do you think that the UK approach is getting the balance right in that area, particularly?
EP: We said when we issued our advice to the Welsh government that we thought that the way that Port Talbot had gone was the wrong way to decarbonise. And by that, we meant [that] you do need to plan ahead for industrial change. It takes time to repurpose sites and to train workers, and there are often longer lead times you end up with by the time government acts.
So the example with Port Talbot in Wales was that everyone knew that that plant was struggling, that there was an opportunity to have an electric arc furnace and there’s just basically been a gap now, between turning off the blast furnaces and starting up the electric arc furnace, because there wasn’t enough early action in the middle. That’s meant there are workers that have lost jobs, that may be an opportunity to redeploy or retrain.
Now, if you contrast that with the closure of Ratcliffe power station, which was the UK’s last coal-fired power station, there was a very long lead, because they knew that the plant would close – not least because of the UK’s carbon budgets. They had a very long process of working with that workforce, to think about how to retrain and redeploy them, and sat down with the unions in the planning. And I think every single worker ended up either retrained or redeployed or retired. That’s a good transition; that’s what you want. And redeployed in the energy sector, right, doing kind of purposeful jobs in their community.
So that’s one answer. [You’ve] got to make sure you do some transition planning and you need a decent industrial policy. I think a lot of other markets, when we’ve looked at it, the difference in our [energy] prices for our industrials are different because of a lack of industrial strategy. So there are incentives and subsidies and things in Europe that don’t exist here. So that produces a competitive difference in the energy price and costs for our industries, which I think is worth looking at. But again, that’s an industrial strategy outside of my remit, but I think that’s missing.
And lastly, I suppose more optimistically, we think that a low-carbon power system [means] electricity [leads to] about 60% of emissions reduction, but it’s also cheap and abundant energy. Industry electrification should therefore have a reduced cost for its energy, which is a big input. They should be able to use new technologies. There should be a really vibrant future for our industrial sector. There’s no reason why there shouldn’t be.
And also, there are opportunities for new industries. I’ve mentioned some of them, but hydrogen, sustainable aviation fuel, carbon capture and storage, there’s loads of stuff that really suits the UK’s heritage in chemicals and in oil and gas. So I think this positioning of “its industrialisation or its net-zero” is wrong.
The other thing I’d say is that narrative tends to miss that we’ve structurally changed what industry means in the UK. So one of the reasons our emissions footprint from heavy industry is down is not because our industries have gone abroad, it is [because] we switched to high-value manufacturing. So we’ve actually grown our manufacturing output in the UK. It’s just a different kind of manufacturing.
I think we actually do need industries like steel in this country. There are huge opportunities for green steel globally. There are huge opportunities for carbon capture. There are huge opportunities for hydrogen. We think we should do those industries here, and [the CCC] said that. But there are also lots of other new industries and manufacturers that we don’t talk about anywhere near enough, and they’re a kind of core driver of the UK economy.

CB: So looking ahead a little bit, by June next year, the government’s going to have to legislate for the seventh carbon budget, which centres on 2040, so we’re looking ahead 15 years, and the committee’s already put out its advice. I think it was an 87% reduction?
EP: 87% emissions reduction between the years of 2038 and 2042, including international aviation and shipping.
CB: Yes. So ahead of that legislation being passed, assuming it will be passed in June, there’s obviously a bit of a process the government will put out, like draft legislation. There’s going to be some sort of impact assessment and debate in parliament and so on.
There’s been a bit of a conversation about whether that process should look different, compared to how previous carbon budgets were passed. Calls for greater scrutiny, more time in parliament and so on. What are you hoping to see out of that process?
EP: Again, we serve [the] government, not the other way around. So they will decide what they think is the most effective way of legislating the target. [Currently the budget] is at the point that we’ve given our advice, [so] it becomes the government’s target [now and] they could accept that advice or reject it. No government ever has. It’s been pretty solid advice so far, but they will take that number, scrutinise it, work out whether it’s the number they’re going to offer parliament and then, as you say, offer their own impact assessment or plans or whatever else around it. And then there’s the debate in parliament.
Once we’ve issued our advice, it only serves to be an independent view for parliament, when they’re having the debate, and we are not in charge of the process at all, though I’m sure they will tell us when they decide what to do.
What we have said, I think, in the past on this is [that] it’s obviously a good thing for parliament to have good numbers and to be able to have a debate. What exactly that looks like is down to parliamentarians and government [to] hash out.
CB: All right, we’ll be watching this space. Slightly different question now. Since you’ve been in this role, chief executive of the Climate Change Committee, there’s been quite a notable number of comment pieces published in newspapers with a kind of misogynistic portrayal of you personally. I’m thinking in pieces in the Daily Mail, Daily Telegraph and Sunday Times. What do you think they’re trying to do with that kind of article?
EP: I don’t know. And actually, I don’t tend to read them,
CB: Probably wise.
EP: Thank you. Good, good. I don’t Google myself. I don’t know. I mean, I think it’s a pretty generic and not surprising observation to say that women in public life have a different experience than men. I have been in public-facing jobs before, so in that sense, that’s not new.
The one thing that I would say is I think some of this job is about representing something and I have been struck that it’s actually – it’s not the gender thing that strikes me. It’s the difference in moving from the private energy market and being an energy person and moving to being a public servant working for the Climate Change Committee. Some of the things I would say about energy prices or energy, as an energy analyst, were taken very differently, even though I’m saying – almost verbatim – the same things about things like energy security and gas dependency and costs than in this job. And that’s actually the thing that I find interesting, there’s been a kind of shift in how that expertise is perceived, because of the role change. Otherwise, yeah, I don’t read the stuff.
CB: We’re in this slightly different, well, very different world, when it comes to the public conversation around climate change at the moment, compared to say even two years ago. How do you think, personally, we could have better conversations about what’s obviously a very challenging topic? And how are you trying to make that happen?
EP: I think we should reach people where they are and the things that they’re worried about. And by that, I mean I think it is completely understandable that climate change can remain an absolute priority issue for people in this country. I’ve seen that in every focus group, poll, the social research that we do, and also just what it’s meant to grow up in this country.
And we are, I think, natural environmentalists. [We are] people care about newts and trees and nature, and I don’t think that’s changed. And I think you see that people do understand that climate change is happening, and they want something done about it, and they worry for their children. And so I think we can talk to them more about why we’re doing this. I think we might have forgotten to do that, actually.
I think we should re-center what this is all about and talk about some of the impacts for the things that we love here. For me, 10 generations of my family have come from the same part of Gloucestershire and I live there now. And there’s a really beautiful valley that I walk in, which is populated by beech trees, which are changing colour at the moment. That species is vulnerable to drought and I think, what would this valley look like if those trees couldn’t grow here anymore? And that, for me, is almost more resonant than everything that I know intellectually about climate from my job. It’s about something really deeply personal. It’s about a legacy I want to pass on to my children, that was passed on to me. We could do more of that I think, you know, really talking to people realistically, without hyperbole about what this means.
And then the other thing is, I think we should acknowledge that it’s challenging in places. I think we should acknowledge we have to build some stuff and that costs money, and it is spend-to-save. We know that savings outstrip costs from about 2040, that if we make the investment in a modern energy system, it will pay back, but you still have to make the investment and it has been a really challenging time for people, and so our message to the government has been, “you have to focus on electricity costs, you have to get bills down”. And the Climate Change Committee is saying that, because we understand that it is important in order for people to stay on board with the transition coming in the economy.
I was the chief executive of the energy trade body during the energy crisis. I know how hard it is for people on their energy bills right now and I don’t think we can tackle net-zero without having the answer to those questions. If you think about the rise in populism in this country, it’s about [the] cost of living and people feeling like the economy isn’t delivering for them. So, of course, you should focus on industrial energy prices. Of course, you should focus on energy bills. These are not incorrect things to say that the public worries about.
I think if you can explain to people why clean electric technologies will, yes, help save the places they love, and do our bit for climate change and look after nature, but also do stuff for bills and industry and jobs. I think that’s really important and the sooner we get those benefits to people, the better. I don’t think we can say, wait. And that’s a long way of saying everyone is right. Actually, we should just have much more pragmatic, open, deliberative conversations and engage with the fact that everyone is right here.
CB: Do you think, though – I mean, because we’re also in a world where there’s increasing levels of misinformation, not only across social media, obviously that goes without saying, but also within traditional media, newspapers and so on. Is everyone right in that sense?
EP: I think we have not put enough effort into, like, fact-checking and making sure there’s accurate information, of course. And we are a body that exists, we’re like the charts people. So if you want accurate charts, then come to us. We’ve got lots of those.
What I mean by everyone’s right is [that] there’s often an underpinning sort of question or narrative, that I think we should just be open to following through. It is about, if renewables are cheap, why is my bill higher? It is about when these new industries will be here and what does it mean for my job? And there’s obviously a cost to building new power plants, so who pays for that? And when?
If you look at the Climate Change Committee’s analysis, you can see that there is a cost to building the infrastructure, that we don’t shy away from, and also that we are worried about energy bills and we’re saying to people, we need more action on that bit of it. The thing that’s often missed is [that] then, you get these massive savings for the economy coming through from 2040 and rolling onto 2050. So I think it’s about engaging with people’s genuine concerns about the how.
I think it’s about being very clear that there are facts, like climate change is happening, it will have impacts, it will have costs. You know, fossil fuels have been, over the last 10 years, volatile [and] 80% of the rise on your bills is because of that. It’s not because of these other things. But you can also say these other things have costs too, and we need to think about how to do it.
So that’s what I mean. And you know, the rest of it is sort of outside my job as a civil servant. But I do think, when we do our social research, when we run our citizens panels, one of the most interesting things is we often get questions about [things] like is climate change man made? Or can you tell us about the impacts? And it only takes 10 minutes with the actual climate scientists and people understand – they’re just looking for really good information. And something else that comes back in our social research is a desire for accurate information, particularly from policymakers.
CB: Do you think that the government should be doing more in terms of having that conversation with the public, trying to explain the why and the what and the how?
EP: The committee in the past has said the government should focus more on communications and that’s because of what comes out of the citizens panels. We run small panels of the public that are demographically and politically diverse, and then spend time with them, asking about – usually – trade-offs. So if there’s a decision on what we’re recommending, that could go either way, getting that sense of what people think and feel is important because, in the Climate Change Act, we’re required to consider social factors. So that’s us doing that bit.
And whenever we do those [panels], people say things like, “Oh, I wish I’d known this before”. Or [that] it’s new information for them. And they often then come around to a recommendation that you should communicate more clearly. So, yeah, yeah.
I think it’s always been an afterthought, as well. It’s hard, isn’t it, when you’ve got so much to do, to want to spend money on doing communication. But we did do that in the past. The last time we did a big upgrade of the electricity system in the 1960s, there was a big public information campaign that went out in all kinds of newspapers and magazines [such as] Country Life. [It] talked about, in long form, why we were building pylons and [a] transmission network across England to get electricity to Wales. And now it’s maybe the inverse.
That’s a really important thing to do when you’re making a big change over. I think we did the same when we were changing over from coal gas to methane in our heating. We’ve done the same with the digital switchover.
So when you’re talking about economic or energy transitions, then we’ve got a good legacy of having communications programs alongside. That’s part [of] the reason the committee said, maybe we should be doing some more of that now.
CB: Yeah, it’s interesting, because it definitely doesn’t feel like that has happened around the changes that are being made or asked for in climate policy.
EP: Have you seen them, the ones from the 1960s ever?
CB: I haven’t. No.
EP: Oh, they’re also quite punchy. It’s worth finding them. There’s one explaining why part of the country is having infrastructure [built] for another part of the country. And there’s one about children and why we’re building infrastructure for the next generation. And I can’t remember the exact headline, but it is something as literal as “Are you going to explain to these small children why you don’t want them to have cheap power in the future?” It’s quite direct.
So, yeah, we used to do that. We used to have no problem doing public information campaigns. Maybe that’s the option here. But again, how it’s done [and at] what level of government, that’s really for policymakers to decide.
CB: Great. Well, that’s [a] perfect segue into my final question. You’ve obviously got young children [and we’ve] just been talking about messages to children. I don’t know if you talk to your kids yet about climate change? How do you think about having that conversation?
EP: We’ve got wind turbines on the hill not far from where I live, and my son, who’s three, has been obsessed with them because they’re going round and round. He likes things that go round and round, see also cars, washing machines, anything that moves. But off the back of that, it’s been quite easy to explain to him that I do something to do with wind turbines. So whenever they see wind turbines, they say, “look, mummy, it’s your job”, which is quite sweet.
I haven’t worked out how to fully explain climate, because they’re six and three. They’re still little. I also, and maybe this is the wrong thing, but I also slightly just want them to live their life as they know it. It’s quite a complex thing [climate change] and small children are quite good at getting worried about stuff they don’t fully understand. We lost a close family member in May and trying to explain death to a three-year-old or a six-year-old – there are some things that are sort of “Big”.
What we do do is talk to them about the fact that my work, the reason I’m not always home, the reason I sometimes miss bedtime, it’s about trying to look after nature. It’s trying to look after the newts in the pond outside, or the beech trees in the valley, and that’s important. And we need to be kind. That’s as far as we’ve got.
I will endeavour to explain atmospheric physics to them before they finish primary school, but I also just want them to enjoy the world as they experience it, too. There’ll be a time for more complex discussions when they get big.
And I suppose that’s a nice segue, because I get asked the question about the kids a lot. It’s about making the world safe enough that they can have a lovely life, of course it is, but I’m aware that some of the loss sits with me, not with them. They will not have memories of how many butterflies there used to be. They’ll just be excited by butterflies. They will experience the world as it is. I would like them to have as many of the experiences that I’ve had, as many grasshoppers in the summer, as many butterflies, as many beautiful, crisp autumn mornings walking the dog to school, but they will ultimately just know the world as it is.
I’m the one [who] has to carry knowing what they’ve lost and I don’t see any reason right now to put that on them. They’re still quite excited when they see a jaybird in the garden.
CB: Great. Well. Thank you very much, Emma. It’s been great to chat with you.

Climate Change
The 2026 budget test: Will Australia break free from fossil fuels?
In 2026, the dangers of fossil fuel dependence have been laid bare like never before. The illegal invasion of Iran has brought pain and destruction to millions across the Middle East and triggered a global energy crisis impacting us all. Communities in the Pacific have been hit especially hard by rising fuel prices, and Australians have seen their cost-of-living woes deepen.
Such moments of crisis and upheaval can lead to positive transformation. But only when leaders act with courage and foresight.
There is no clearer statement of a government’s plans and priorities for the nation than its budget — how it plans to raise money, and what services, communities, and industries it will invest in.
As we count down the days to the 2026-27 Federal Budget, will the Albanese Government deliver a budget for our times? One that starts breaking the shackles of fossil fuels, accelerates the shift to clean energy, protects nature, and sees us work together with other countries towards a safer future for all? Or one that doubles down on coal and gas, locks in more climate chaos, and keeps us beholden to the whims of tyrants and billionaires.
Here’s what we think the moment demands, and what we’ll be looking out for when Treasurer Jim Chalmers steps up to the dispatch box on 12 May.
1. Stop fuelling the fire
2. Make big polluters pay
3. Support everyone to be part of the solution
4. Build the industries of the future
5. Build community resilience
6. Be a better neighbour
7. Protect nature
1. Stop fuelling the fire

In mid-April, Pacific governments and civil society met to redouble their efforts towards a Fossil Fuel Free Pacific. Moving beyond coal, oil and gas is fundamental to limiting warming to 1.5°C — a survival line for vulnerable communities and ecosystems. And as our Head of Pacific, Shiva Gounden, explained, it is “also a path of liberation that frees us from expensive, extractive and polluting fossil fuel imports and uplifts our communities”.
Pacific countries are at the forefront of growing global momentum towards a just transition away from fossil fuels, and it is way past time for Australia to get with the program. It is no longer a question of whether fossil fuel extraction will end, but whether that end will be appropriately managed and see communities supported through the transition, or whether it will be chaotic and disruptive.
So will this budget support the transition away from fossil fuels, or will it continue to prop up coal and gas?
When it comes to sensible moves the government can make right now, one stands out as a genuine low hanging fruit. Mining companies get a full rebate of the excise (or tax) that the rest of us pay on diesel fuel. This lowers their operating costs and acts as a large, ongoing subsidy on fossil fuel production — to the tune of $11 billion a year!
Greenpeace has long called for coal and gas companies to be removed from this outdated scheme, and for the billions in savings to be used to support the clean energy transition and to assist communities with adapting to the impacts of climate change. Will we see the government finally make this long overdue change, or will it once again cave to the fossil fuel lobby?
2. Make big polluters pay

While our communities continue to suffer the escalating costs of climate-fuelled disasters, our Government continues to support a massive expansion of Australia’s export gas industry. Gas is a dangerous fossil fuel, with every tonne of Australian gas adding to the global heating that endangers us all.
Moreover, companies like Santos and Woodside pay very little tax for the privilege of digging up and selling Australians’ natural endowment of fossil gas. Remarkably, the Government currently raises more tax from beer than from the Petroleum Resource Rent Tax (PRRT) — the main tax on gas profits.
Momentum has been building to replace or supplement the PRRT with a 25% tax on gas exports. This could raise up to $17 billion a year — funds that, like savings from removing the diesel tax rebate for coal and gas companies, could be spent on supporting the clean energy transition and assisting communities with adapting to worsening fires, floods, heatwaves and other impacts of climate change.
As politicians arrive in Canberra for budget week, they will be confronted by billboards calling for a fair tax on gas exports. The push now has the support of dozens of organisations and a growing number of politicians. Let’s hope the Treasurer seizes this rare window for reform.
3. Support everyone to be part of the solution
As the price of petrol and diesel rises, electric vehicles (EVs) are helping people cut fuel use and save money. However, while EV sales have jumped since the invasion of Iran sent fuel prices rising, they still only make up a fraction of total new car sales. This budget should help more Australians switch to electric vehicles and, even more importantly, enable more Australians to get around by bike, on foot, and on public transport. This means maintaining the EV discount, investing in public and active transport, and removing tax breaks for fuel-hungry utes and vans.
Millions of Australians already enjoy the cost-saving benefits of rooftop solar, batteries, and getting off gas. This budget should enable more households, and in particular those on lower incomes, to access these benefits. This means maintaining the Cheaper Home Batteries Program, and building on the Household Energy Upgrades Fund.
4. Build the industries of the future

If we’re to transition away from fossil fuels, we need to be building the clean industries of the future.
No state is more pivotal to Australia’s energy and industrial transformation than Western Australia. The state has unrivaled potential for renewable energy development and for replacing fossil fuel exports with clean exports like green iron. Such industries offer Western Australia the promise of a vibrant economic future, and for Australia to play an outsized positive role in the world’s efforts to reduce emissions.
However, realising this potential will require focussed support from the Federal Government. Among other measures, Greenpeace has recommended establishing the Australasian Green Iron Corporation as a joint venture between the Australian and Western Australian governments, a key trading partner, a major iron ore miner and steel makers. This would unite these central players around the complex task of building a large-scale green iron industry, and unleash Western Australia’s potential as a green industrial powerhouse.
5. Build community resilience
Believe it or not, our Government continues to spend far more on subsidising fossil fuel production — and on clearing up after climate-fuelled disasters — than it does on helping communities and industries reduce disaster costs through practical, proven methods for building their resilience.
Last year, the Government estimated that the cost of recovery from disasters like the devastating 2022 east coast floods on 2019-20 fires will rise to $13.5 billion. For contrast, the Government’s Disaster Ready Fund – the main national source of funding for disaster resilience – invests just $200 million a year in grants to support disaster preparedness and resilience building. This is despite the Government’s own National Emergency Management Agency (NEMA) estimating that for every dollar spent on disaster risk reduction, there is a $9.60 return on investment.
By redirecting funds currently spent on subsidising fossil fuel production, the Government can both stop incentivising climate destruction in the first place, and ensure that Australian communities and industries are better protected from worsening climate extremes.
No communities have more to lose from climate damage, or carry more knowledge of practical solutions, than Aboriginal and Torres Strait Islander peoples. The budget should include a dedicated First Nations climate adaptation fund, ensuring First Nations communities can develop solutions on their own terms, and access the support they need with adapting to extreme heat, coastal erosion and other escalating challenges.
6. Be a better neighbour
The global response to climate change depends on the adequate flow of support from developed economies like Australia to lower income nations with shifting to clean energy, adapting to the impacts of climate change, and addressing loss and damage.
Such support is vital to building trust and cooperation, reducing global emissions, and supporting regional and global security by enabling countries to transition away from fossil fuels and build greater resilience.
Despite its central leadership role in this year’s global climate negotiations, our Government is yet to announce its contribution to international climate finance for 2025-2030. Greenpeace recommends a commitment of $11 billion for this five year period, which is aligned with the global goal under the Paris Agreement to triple international climate finance from current levels.
This new commitment should include additional funding to address loss and damage from climate change and a substantial contribution to the Pacific Resilience Facility, ensuring support is accessible to countries and communities that need it most. It should also see Australia get firmly behind the vision of a Fossil Fuel Free Pacific.
7. Protect nature

There is no safe planet without protection of the ecosystems and biodiversity that sustain us and regulate our climate.
Last year the Parliament passed important and long overdue reforms to our national environment laws to ensure better protection for our forests and other critical ecosystems. However, the Government will need to provide sufficient funding to ensure the effective implementation of these reforms.
Greenpeace has recommended $500 million over four years to establish the National Environment Agency — the body responsible for enforcing and monitoring the new laws — and a further $50 million to Environment Information Australia for providing critical information and tools.
Further resourcing will also be required to fulfil the crucial goal of fully protecting 30% of Australian land and seas by 2030. This should include $1 billion towards ending deforestation by enabling farmers and loggers to retool away from destructive practices, $2 billion a year for restoring degraded lands, $5 billion for purchasing and creating new protected areas, and $200 million for expanding domestic and international marine protected areas.
Conclusion
This is not the first time that conflict overseas has triggered an energy crisis, or that a budget has been preceded by a summer of extreme weather disasters, highlighting the urgent need to phase out fossil fuels. What’s different in 2026 is the availability of solutions. Renewable energy is now cheaper and more accessible than ever before. Global momentum is firmly behind the transition away from fossil fuels. The Albanese Government, with its overwhelming majority, has the chance to set our nation up for the future, or keep us stranded in the past. Let’s hope it makes some smart choices.
The 2026 budget test: Will Australia break free from fossil fuels?

What fossil fuels really cost us in a world at war
Anne Jellema is Executive Director of 350.org.
The war on Iran and Lebanon is a deeply unjust and devastating conflict, killing civilians at home, destroying lives, and at the same time sending shockwaves through the global economy. We, at 350.org, have calculated, drawing on price forecasts from the International Monetary Fund (IMF) and Goldman Sachs, just how much that volatility is costing us.
Even under the IMF’s baseline scenario – a de facto “best case” scenario with a near-term end to the war and related supply chain disruptions – oil and gas price spikes are projected to cost households and businesses globally more than $600 billion by the end of the year. Under the IMF’s “adverse scenario”, with prolonged conflict and sustained price pressures, we estimate those additional costs could exceed $1 trillion, even after accounting for reduced demand.
Which is why we urgently need a power shift. Governments are under growing pressure to respond to rising fuel and food costs and deepening energy poverty. And it’s becoming clearer to both voters and elected officials that fossil dependence is not only expensive and risky, but unnecessary.
People who can are voting with their wallets: sales of solar panels and electric vehicles are increasing sharply in many countries. But the working people who have nothing to spare, ironically, are the ones stuck with using oil and gas that is either exorbitantly expensive or simply impossible to get.
Drain on households and economies
In India, street food vendors can’t get cooking gas and in the Philippines, fishermen can’t afford to take their boats to sea. A quarter of British people say that rising energy tariffs will leave them completely unable to pay their bills. This is the moment for a global push to bring abundant and affordable clean energy to all.
In April, we released Out of Pocket, our new research report on how fossil fuels are draining households and economies. We were surprised by the scale of what we found. For decades, governments have reassured people that energy price spikes are unfortunate but unavoidable – the result of distant conflicts, market forces or geopolitical shocks beyond anyone’s control. But the numbers tell a different story.
What we are living through today is not an energy crisis. It is a fossil fuel crisis. In just the first 50 days of the Middle East conflict, soaring oil and gas prices have siphoned an estimated $158 billion–$166 billion from households and businesses worldwide. That is money extracted directly from people’s pockets and transferred, almost instantly, into fossil fuel company balance sheets. And this figure only captures the immediate impact of price spikes, not the permanent economic drain of fossil dependence. Fossil fuels don’t just cost us once, they cost us over and over again.
First, through our bills. Every time there is a war, an embargo or a supply disruption, fossil fuel prices surge. For ordinary people, this means higher costs for energy, transport and food. Many Global South countries have little or no fiscal space to buffer the shock; instead, workers and families pay the price.
Second, through our taxes. Governments around the world continue to pour vast sums of public money into fossil fuel subsidies. These are often justified as a way to protect the most vulnerable at the petrol pump or in their homes. But in reality, the benefits are overwhelmingly captured by wealthier households and corporations. The poorest 20% receive just a fraction of this support, while public finances are drained.
Third, through climate impacts. New research across more than 24,000 global locations gives a granular account of the true costs of extreme heat, sea level rise and falling agricultural yields. Using this data to update IMF modelling of the social cost of carbon, we found that fossil fuel impacts on health and livelihoods amount to over $9 trillion a year. This is the biggest subsidy of all, because these massive and mounting costs are not charged to Big Oil – they are paid for by governments and households, with the poorest shouldering the lion’s share.
Massive transfer of wealth to fossil fuel industry
Adding up direct subsidies, tax breaks and the unpaid bill for climate damages, the total transfer of wealth from the public to the fossil fuel industry amounts to $12 trillion even in a “normal” year without a global oil shock. That’s more than 50% higher than the IMF has previously estimated, and equivalent to a staggering $23 million a minute.
The fossil fuel industry has become extraordinarily adept at profiting from instability. When conflict drives up prices, companies do not lose, they gain. In the current crisis, oil producers and commodity traders are on track to secure tens of billions of dollars in additional windfall profits, even as households face rising bills and governments struggle to manage the fallout.
Fossil fuel crisis offers chance to speed up energy transition, ministers say
This growing disconnect is impossible to ignore. Investors are advised to buy into fossil fuel firms precisely because of their ability to generate profits in times of crisis. Meanwhile, ordinary people are told to tighten their belts.
In 2026, unlike during the oil shocks of the 1970s, clean energy is no longer a distant alternative. Now, even more than when gas prices spiked due to Russia’s invasion of Ukraine in 2022, renewables are often the cheapest option available. Solar and wind can be deployed quickly, at scale, and without the volatility that defines fossil fuel markets.
How to transition from dirty to clean energy
The solutions are clear. Governments must implement permanent windfall taxes on fossil fuel companies to ensure that extraordinary profits generated during crises are redirected to support households. These revenues can be used to reduce energy bills, invest in public services, and accelerate the rollout of clean energy.
Second, we must shift subsidies away from fossil fuels and towards renewable solutions, particularly those that can be deployed quickly and equitably, such as rooftop and community solar. This is not just about cutting emissions. It is about building a more stable, fair and resilient energy system.
Finally, we need binding plans to phase out fossil fuels altogether, replacing them with homegrown renewable energy that can shield economies from future shocks. Because what the current crisis has made clear is this: as long as we remain dependent on fossil fuels, we remain vulnerable – to conflict, to price volatility and to the escalating impacts of climate change.
The true price of fossil fuels is no longer hidden. It is visible in rising bills, strained public finances and communities pushed to the brink. And it is being paid, every day, by ordinary people around the world.
It’s time for the great power shift.

Traditional models still ‘outperform AI’ for extreme weather forecasts
Computer models that use artificial intelligence (AI) cannot forecast record-breaking weather as well as traditional climate models, according to a new study.
It is well established that AI climate models have surpassed traditional, physics-based climate models for some aspects of weather forecasting.
However, new research published in Science Advances finds that AI models still “underperform” in forecasting record-breaking extreme weather events.
The authors tested how well both AI and traditional weather models could simulate thousands of record-breaking hot, cold and windy events that were recorded in 2018 and 2020.
They find that AI models underestimate both the frequency and intensity of record-breaking events.
A study author tells Carbon Brief that the analysis is a “warning shot” against replacing traditional models with AI models for weather forecasting “too quickly”.
AI weather forecasts
Extreme weather events, such as floods, heatwaves and storms, drive hundreds of billions of dollars in damages every year through the destruction of cropland, impacts on infrastructure and the loss of human life.
Many governments have developed early warning systems to prepare the general public and mobilise disaster response teams for imminent extreme weather events. These systems have been shown to minimise damages and save lives.
For decades, scientists have used numerical weather prediction models to simulate the weather days, or weeks, in advance.
These models rely on a series of complex equations that reproduce processes in the atmosphere and ocean. The equations are rooted in fundamental laws of physics, based on decades of research by climate scientists. As a result, these models are referred to as “physics-based” models.
However, AI-based climate models are gaining popularity as an alternative for weather forecasting.
Instead of using physics, these models use a statistical approach. Scientists present AI models with a large batch of historical weather data, known as training data, which teaches the model to recognise patterns and make predictions.
To produce a new forecast, the AI model draws on this bank of knowledge and follows the patterns that it knows.
There are many advantages to AI weather forecasts. For example, they use less computing power than physics-based models, because they do not have to run thousands of mathematical equations.
Furthermore, many AI models have been found to perform better than traditional physics-based models at weather forecasts.
However, these models also have drawbacks.
Study author Prof Sebastian Engelke, a professor at the research institute for statistics and information science at the University of Geneva, tells Carbon Brief that AI models “depend strongly on the training data” and are “relatively constrained to the range of this dataset”.
In other words, AI models struggle to simulate brand new weather patterns, instead tending forecast events of a similar strength to those seen before. As a result, it is unclear whether AI models can simulate unprecedented, record-breaking extreme events that, by definition, have never been seen before.
Record-breaking extremes
Extreme weather events are becoming more intense and frequent as the climate warms. Record-shattering extremes – those that break existing records by large margins – are also becoming more regular.
For example, during a 2021 heatwave in north-western US and Canada, local temperature records were broken by up to 5C. According to one study, the heatwave would have been “impossible” without human-caused climate change.
The new study explores how accurately AI and physics-based models can forecast such record-breaking extremes.
First, the authors identified every heat, cold and wind event in 2018 and 2020 that broke a record previously set between 1979 and 2017. (They chose these years due to data availability.) The authors use ERA5 reanalysis data to identify these records.
This produced a large sample size of record-breaking events. For the year 2020, the authors identified around 160,000 heat, 33,000 cold and 53,000 wind records, spread across different seasons and world regions.
For their traditional, physics-based model, the authors selected the High RESolution forecast model from the Integrated Forecasting System of the European Centre for Medium-Range Weather Forecasts. This is “widely considered as the leading physics-based numerical weather prediction model”, according to the paper.
They also selected three “leading” AI weather models – the GraphCast model from Google Deepmind, Pangu-Weather developed by Huawei Cloud and the Fuxi model, developed by a team from Shanghai.
The authors then assessed how accurately each model could forecast the extremes observed in the year 2020.
Dr Zhongwei Zhang is the lead author on the study and a researcher at Karlsruhe Institute of Technology. He tells Carbon Brief that many AI weather forecast models were built for “general weather conditions”, as they use all historical weather data to train the models. Meanwhile, forecasting extremes is considered a “secondary task” by the models.
The authors explored a range of different “lead times” – in other words, how far into the future the model is forecasting. For example, a lead time of two days could mean the model uses the weather conditions at midnight on 1 January to simulate weather conditions at midnight on 3 January.
The plot below shows how accurately the models forecasted all extreme events (left) and heat extremes (right) under different lead times. This is measured using “root mean square error” – a metric of how accurate a model is, where a lower value indicates lower error and higher accuracy.
The chart on the left shows how two of the AI models (blue and green) performed better than the physics-based model (black) when forecasting all weather across the year 2020.
However, the chart on the right illustrates how the physics-based model (black) performed better than all three AI models (blue, red and green) when it came to forecasting heat extremes.

The authors note that the performance gap between AI and physics-based models is widest for lower lead times, indicating that AI models have greater difficulty making predictions in the near future.
They find similar results for cold and wind records.
In addition, the authors find that AI models generally “underpredict” temperature during heat records and “overpredict” during cold records.
The study finds that the larger the margin that the record is broken by, the less well the AI model predicts the intensity of the event.
‘Warning shot’
Study author Prof Erich Fischer is a climate scientist at ETH Zurich and a Carbon Brief contributing editor. He tells Carbon Brief that the result is “not unexpected”.
He adds that the analysis is a “warning shot” against replacing traditional models with AI models for weather forecasting “too quickly”.
The analysis, he continues, is a “warning shot” against replacing traditional models with AI models for weather forecasting “too quickly”.
AI models are likely to continue to improve, but scientists should “not yet” fully replace traditional forecasting models with AI ones, according to Fischer.
He explains that accurate forecasts are “most needed” in the runup to potential record-breaking extremes, because they are the trigger for early warning systems that help minimise damages caused by extreme weather.
Leonardo Olivetti is a PhD student at Uppsala University, who has published work on AI weather forecasting and was not involved in the study.
He tells Carbon Brief that “many other studies” have identified issues with using AI models for “extremes”, but this paper is novel for its specific focus on extremes.
Olivetti notes that AI models are already used alongside physics-based models at “some of the major weather forecasting centres around the world”. However, the study results suggest “caution against relying too heavily on these [AI] models”, he says.
Prof Martin Schultz, a professor in computational earth system science at the University of Cologne who was not involved in the study, tells Carbon Brief that the results of the analysis are “very interesting, but not too surprising”.
He adds that the study “justifies the continued use of classical numerical weather models in operational forecasts, in spite of their tremendous computational costs”.
Advances in forecasting
The field of AI weather forecasting is evolving rapidly.
Olivetti notes that the three AI models tested in the study are an “older generation” of AI models. In the last two years, newer “probabilistic” forecast models have emerged that “claim to better capture extremes”, he explains.
The three AI models used in the analysis are “deterministic”, meaning that they only simulate one possible future outcome.
In contrast, study author Engelke tells Carbon Brief that probabilistic models “create several possible future states of the weather” and are therefore more likely to capture record-breaking extremes.
Engelke says it is “important” to evaluate the newer generation of models for their ability to forecast weather extremes.
He adds that this paper has set out a “protocol” for testing the ability of AI models to predict unprecedented extreme events, which he hopes other researchers will go on to use.
The study says that another “promising direction” for future research is to develop models that combine aspects of traditional, physics-based weather forecasts with AI models.
Engelke says this approach would be “best of both worlds”, as it would combine the ability of physics-based models to simulate record-breaking weather with the computational efficiency of AI models.
Dr Kyle Hilburn, a research scientist at Colorado State University, notes that the study does not address extreme rainfall, which he says “presents challenges for both modelling and observing”. This, he says, is an “important” area for future research.
