Greg Jackson is the founder and CEO of Octopus Energy, a global energy and technology company headquartered in London.
Set up in 2016, it now has 7.2 million customers across 18 countries, as well as a portfolio of £6bn worth of renewable energy assets. The group’s proprietary technology platform, Kraken, is now used to run more than 40m customer accounts across the globe.
The company’s energy supplier arm recently became the largest in Great Britain, surpassing legacy giant British Gas when it added 1.3 million customers after buying Shell Energy in late 2023.
Jackson is a “serial tech entrepreneur”, having built and sold a number of start-ups before Octopus Energy.
Carbon Brief sat down with him for an hour, to discuss the UK’s energy transition, the upcoming general election, misinformation in the media and much more.
- On the energy transition: “The reality is that it just boils down to electrification.”
- On technology neutrality: “This isn’t primary school, there are going to be winners and losers.”
- On Labour’s “zero-carbon power by 2030” pledge: “It’s totally achievable.”
- On using hydrogen for heating: “It’s like flushing our toilets with champagne. It might work, but it’s inordinately expensive and impractical.”
- On renewable forecasts being revised upwards: “It’s like Groundhog Day when you look at the revised [solar and wind] forecasts.”
- On misinformation in the media: “I think some of it is organised and some of it is cultural…EVs have taken 1.8m barrels of oil off the road per day. That’s enough that the global oil industry is suddenly seeing what used to look like a minor inconvenience in the future is suddenly a real and present danger.”
- On the psychology of climate change: “I think hope is as important, knowing there is a solution, is as important as knowing there’s a problem.”
- On stopping “burning stuff”: “Look at the cost curves for solar and wind and all the other technologies…Honestly, it’s going to be cheaper to stop burning stuff. That was an amazing moment, when I realised that we didn’t have to arrange the forces for saving the planet against the force of economics, because they actually lined up.”
- On the cost of renewables: “Our addiction to fossil fuel is so damaging, it even makes the solutions to fossil fuels more expensive.”
- On investment: “The demand for electricity is only going to go up. And when there’s demand for a product, you can invest in producing it.”
- On the demand flexibility service: “It’s just the equivalent of supermarkets pricing goods to clear, rather than letting them go off.”
- On concerns over digital exclusion: “People who try to hold new technology to the bar of universality are typically protecting some sort of legacy against the technology improvements that benefit consumers, and we should not have much patience for that.”
Carbon Brief: What do you think should be the key priorities when it comes to energy and climate policy for the next [UK] government over its first six months or so?
Greg Jackson: I think the energy transition used to sound like quite a complicated process. The reality is that it just boils down to electrification. We need to electrify everything we can and then be generating as much electricity as we can from renewable resources.
Now, underneath that, there may be a whole lot of policy priorities. But electrification has got to be the one word.
CB: So, when the next government comes in, whenever the election is, are there specific things you really need to see, or that you’d like to see, to really ramp up this decarbonisation process?
GJ: So, again, I’m going to talk about, for me [its] electrification. Because even when we talk about decarbonisation you’re kind of weighing up loads of different things. If we talk about electrification, primarily, then we can say, OK, what does that take?
And I think the first thing we need to do is recognise that, even today, the electricity markets we’ve got are not fit for purpose. We spend billions a year balancing and curtailing renewables – that’s turning windfarms off when it’s windy. And we need a market that means that, at the times when we’re generating a lot of electricity, it’s super cheap for people. And we need to do that on a regional basis, or even more locally than that.
So that, for example, if today we had regional pricing, every region would be cheaper than it is because we’ve been reducing waste. But, more than that, Scotland would be the cheapest electricity in Europe. These are important because as soon as people can see that renewables can lead to cheaper energy, we get public support for renewables – as we should – and it becomes a much more efficient system. We’re not putting a cost on everyone’s bills to pay for waste, which is what happens today.
I think, alongside market reform, you then get the right investment signals. So we are going to be investing in the places that need the infrastructure. And that’s not just generation, it can be things like batteries.
It’s kind of mad at the moment that a lot of people think we should put batteries next to windfarms. But, if you do that, then before anybody’s had a chance to make the most of cheap electricity, you’ve already eliminated the price signal. So the best places for batteries, for example, might be close to population centres.
Take somewhere like the southeast [of England], where, obviously, it’s hard to build new generation. But we can build infrastructure that will make electricity cheaper by, for example, deploying batteries in places that have got peak time constraints [to] enable us to reduce peak issues and benefit more from the times it’s off peak and we can store that electricity.
So I think market reform is absolutely number one. And that means the most dynamic pricing possible.
By the way, it doesn’t mean that consumers will necessarily face dynamic prices, just to be really clear. Companies will be able to wrap-up that dynamic pricing in any number of tariffs. So, for those who want it, you’ll still have flat tariffs – and they’ll probably be cheaper than they are today, because the system is more efficient. But, for those who can shift demand, or want more dynamic stuff, it will enable them to benefit by using electricity more efficiently and that makes for a more efficient system for everyone.
Obviously, we need reform of two sets of regulations. We critically need grid reform, so that you can actually connect stuff to the grid. We’ve spent years talking about this publicly because of the frustration that we’ve got enormous amounts of capital to build new generation. But you can’t. You literally have no way of connecting to the grid. I mean, there’s a project we’ve got to build a solar farm in County Durham, where I think there’s a 14-year wait to connect it.
CB: So is that just planning reform?
GJ: That is grid reform. So, basically in the UK – and, by the way, this applies in many other countries as well – you’ve got a national monopoly grid and you can only build new generation if you can connect it to the grid. You haven’t got any alternative. So, if the grid tells you you’re going have to wait 14 years, you’re going to wait 14 years.
And I contrast this with what has happened in gas. During the energy crisis, Germany alone built five liquified natural gas terminals in one year. Meanwhile, because of these grid connection issues, we can’t build new renewables. And I think that the reform for that is largely bureaucratic; the government and grid need to agree on a process to enable stuff to be connected faster.
The second thing, of course, is planning. And I think, at the moment, I mean, famously, England built two onshore wind turbines in the time that Ukraine during a war built hundreds, because you can’t get planning permission. And that doesn’t just apply for wind turbines, there’s a real challenge building the infrastructure to transmit electricity around the country.
And I think the reality with this is we need to find ways to enable communities to benefit when we build new infrastructure. Wherever you build it, you get NIMBYs [“not in my back yard”]. But we need to have IMBYs as well, people who will directly benefit and can see the direct benefit of building infrastructure. And so we need reform that enables us to deploy new electricity infrastructure, but in a way which embraces, to the maximum extent possible, local communities.
Between those two priorities – i.e. market reform, planning and grid reform – we can unleash the forces that actually will mean that throughout most of the country – everywhere, in fact – consumers will be benefiting from clean energy. And the moment people are benefiting – it’s like when the new iPhone launched. The sudden demand for data meant that the mobile networks just had to build masts, because it had to meet consumer demand. And we can do that with energy, with clean energy, which is the more we enable people to benefit, the more demand there will be for rapid transition. And that’s what we need.
CB: So, moving on to Labour’s now kind of quite high-profile pledge to get net-zero power by 2030…is that broadly achievable? Is that doable if what you laid out there gets implemented? Or are there extra things that, to hit that 2030 target, would need to happen?
GJ: It’s totally achievable. And, by the way, I mean, the government’s pledge [for 2035] is not that different, right? Everyone’s pledging net-zero carbon electricity by roughly then, I can’t remember all the details, but they’re all quite similar.
But the reality is, what it does need is commitment. I was recently at a meeting of governments. Lots of industries were lobbying governments to say: we need to be technology neutral, everyone’s got to be given a chance to be part of this future. Which is all lovely, but this isn’t primary school, there are going to be winners and losers. And we need the commitments from governments that enable investors to invest in the stuff that’s going to be part of the future.
So a really good example would be, there is still this kind of crazy suggestion that hydrogen might be used to heat homes. I mean, it might just be physically possible, but it’s like flushing our toilets with champagne. It might work, but it’s inordinately expensive and impractical. It’s just a delaying tactic from the companies who own the gas infrastructure.
Now, of course, a transition that means that the gas infrastructure, over time, won’t be so valuable, or may even become entirely redundant, is not the future that they [the gas industry] want. But it’s not like we’re still running stuff down the canals. The technology changes already made [mean] that renewable electricity is the cheapest form of power we’ve ever had and is getting cheaper every year. Of course, there are minor blips like recent inflation in offshore wind, but even that was driven by the inflation and interest rates, which largely came from our addiction to fossil fuels.
So, the path should be clear, and what we need from policymakers are those brave decisions that say: “Hey, look, there are going to be some losers in this process.” But…the quicker we’re clear about that, the more we can embrace, for example, the workers in those sectors and make sure that they’ve got a bright future, as we transition, and the more we can manage the transition in a way which will be good. Good for the people who were affected by it.
CB: Can the market do all of this? Or Labour’s talking of GB Energy, and you hear about nationalisation or quasi-nationalisation of the railways. What do you make of the ideas like GB Energy?
GJ: Yeah. I don’t think there’s any read-across from railways. It’s an entirely different sector. And the reality when you look at energy, I mean, first of all, GB Energy isn’t the sort of nationalised energy supplier, which is good, by the way. I mean, energy retail is one of the most competitive sectors in the UK. Margins are 2%, if energy companies are lucky.
The big problem in energy is the rest of the cost stack. It’s largely those kinds of very regulated, often monopoly parts of the system, which need reform. And so I think if GB Energy is about, for example, helping pioneer stuff that isn’t yet ready for market risk…I mean, take tidal as an example. Maybe we should have tidal power, maybe GB Energy would be a great way of kick-starting that, in the same way as government subsidies kick-started a lot of wind and solar. But, increasingly, we could run wind and solar on a merchant basis, i.e. an unsubsidised basis in many energy systems if you’ve had the market reform I talked about. So, if GB energy is helping kickstart stuff we need, that would be incredible.
If GB Energy helps get government backing for projects to enable them to, for example, overcome some of the planning and connections issues that I’ve described, that could be great. So it really depends on the role GB Energy is playing.
CB: Before we started speaking, I was looking at this Ladybird book from 1981, which I picked up from a charity shop, talking about energy conservation. Obviously, whatever that is, 40-odd years ago [and we’re now] talking about 2050 [for net-zero emissions]. What, in your view, does the UK energy system, EVs and all the rest of it look like then? What does the UK look like in 2050? And what does it need to look like?
GJ: So, first of all, I guess the question here is, if this [book] was roughly 30 years ago and 2050 is roughly 30 years away…how well did this predict where we are today? Or how dated does it look, right?
Look, I think a real challenge with targets like 2050 is that almost everyone who sets those targets will be retired by then. They’re not responsible for it. Indeed, almost everyone who’s working for them will be retired by then. It’s incredibly easy to set a target that you’re not going to be around for.
So, I’m much more of a believer in setting much shorter term targets. And given that we have the technologies we have available today, we can set really challenging targets. If you are talking about 2030, for example, net-zero electricity, that’s a much more tangible time. Because it tells us about the decisions we need to make right now.
I think one of the interesting things about predicting the future, is how wrong we get it, especially in sectors like energy, where you’ve got very powerful incumbents who have very strong views about what the future will be, but are often wrong. I mean, Kodak’s view of the future was wrong, Nokia’s view of the future was wrong, Blockbusters’ view. They were all wrong. But they didn’t get to lobby for their view of the future, they just had to compete. And the market and technology made the decision for them.
So I think if I look at energy, wind and solar, [they] have repeatedly beaten every target. They get cheaper, faster than anyone’s ever estimated. And it keeps on happening. It’s like Groundhog Day when you look at the revised forecasts, because every forecast that comes out, kind of looks back and goes: “Whoops, we underestimated how well solar would do or how well wind would do.” And then they make an estimate, and then they have to go and do the exact same process again because it keeps beating it.
It’s been the same, by the way, with batteries. Battery prices keep on plummeting way ahead of expectation. And EV adoption has kept on accelerating ahead of expectation. So, all the clean-energy technologies beat the forecasts.
By the way, the only ones that don’t are the dirty-energy technologies. No one forecast the horrific gas crisis we’ve just lived through. Nuclear keeps getting – and I’m not anti nuclear – but it keeps getting more expensive and slower than expected. And so I think the challenge with setting things like 2050 is, if we start building infrastructure based around our best guesses now, it’ll almost certainly under-deliver and it will cost too much. We’re far better off with the kind of things I talked about at the beginning, which were market reforms, so we can rapidly deploy the technologies we’ve already got.
An incredible thing that happens in technology is, each time you deploy something, it teaches you about what is possible. When the iPhone launched, no one foresaw that QR codes would get you out of a pandemic, or that Uber would change the global cab industry.
In the same way, for example, we are already discovering that if we give people, if we integrate our technologies directly with people’s electric cars, we can charge them at three or four times less than grid cost, because we’re able to grab the electricity when it’s most abundant. That means that, today, for some of our customers, they can drive electric cars for £2.30 for 100 miles, whereas with a diesel car it would be £18.
Now, no one forecast that kind of thing. It’s just what we discover, when we build out new technology. And that’s why, you know, I really believe we need the reforms to let us build the technology. And we will discover it gets cheaper, faster, easier and better for consumers, far more quickly than anyone realised.
CB: What do you make of the current mood in certain sections of the media, which is very negative, relentlessly attacking EVs, electrification, solar? What’s your view on that? It’s almost like organised misinformation, it sometimes feels like.
GJ: I think there are two layers to it. I think some of it is organised and some of it is cultural.
Let’s talk about the cultural first. Let’s look at EVs. EVs are not just an electric version of petrol cars, they are a fundamentally different creation. So, the assumption that, for example, the long-standing car makers, the manufacturers of Europe and elsewhere, were going to be able to just start making EVs, is kind of wrong. Right? They spent 100 years becoming unbelievably good at complex transmission and drive shafts and all of the engineering required to take what is actually a remarkably complex thing, a petrol or diesel engine, and turn it into a consumer device.
Meanwhile, for the last 20 years a bunch of Chinese companies that just set out to build EVs from the beginning, or Tesla, which has only ever done EVs, have re-engineered cars, built around the fundamentals of an EV, in which things like transmission becomes much simpler, but your ability to build really smart battery management, really smart software is actually a competitive edge.
Now, what we’re seeing at the moment is EVs emerging that traditional automakers find very, very difficult to compete with. And, so, their answer is: “Hang on, we can’t make money in EVs. Therefore, something’s wrong with EVs.” Because no company ever says there’s something wrong with us.
Now, that means that everyone in those companies, there’s huge numbers of people there, good people, but that are genuinely thinking EVs are too hard, they are too challenging, they’re not going to work. And they’re the people that have a 20-year relationship with motoring journalists. Their lobbyists have had the 20-year relationships with the political correspondents, their CEOs are the ones that have the relationships with the business journalists and with the editors. So, this isn’t a conspiracy, it’s just that those companies are facing existential threat from something that is really challenging for them. And that means that all the conversations these people have are about the problems with EVs, right?
Now, actually, I have lived with an EV for seven years. There are very, very few problems with an EV. And, you know, for example, the latest generation of EVs are getting cheaper and cheaper and cheaper, as all the technology scales up. And we get these great cost curves as batteries come down. But those automakers are not seeing it, in fact, this is a threat to them.
So, I think the primary layer here is simply that the influential people in the motoring industry, simply don’t get EVs.
I think the second thing is, of course, there is a backlash from the fossil fuel industry, including some car companies, because, even today, I think EVs have taken 1.8m barrels of oil off the road per day. Right? That’s enough that the global oil industry is suddenly seeing what used to look like a minor inconvenience in the future is suddenly a real and present danger. Now, we saw the ability of the tobacco industry to lobby against tobacco restrictions. The oil industry is vastly more powerful than tobacco ever was. And so, on top of the sort of cultural thing that I’ve described, you have then got a genuine concern and lobbying efforts.
And I guess the last part of that is cultural wars. There are organisations who deny climate change, who are combining anti-climate change with anti-EV, with anti-renewables and a whole load of other social topics to try and create political divides. That’s why when I talk about the market reforms that will make, for example, clean energy cheaper, it’s so critical, because if we can show people this transition is good for them, we kind of undermine that attempt at a culture war.
I spend a lot of time talking to, for example, people on the political right, because they are free marketers. They believe in entrepreneurship, they believe in efficiency and talking to them about the way in which renewables and EVs can lead to a more efficient competitive world. Actually, we make the culture war go away and we talk about the economics instead. And then we can align people’s self-interest with that industry, with that of the climate.
CB: Talking about a culture war, we obviously got an election here in the UK looming, but we’ve obviously got a US election looming too and a very, very stark choice between a Biden versus Trump presidency. In that context, given what the Trump 1.0 presidency did, what do you make of the Paris Agreement? Obviously, Trump tried to pull, or did pull the US out of it and then Biden reinstated it. Do you think the Paris Agreement has achieved things to date? Is it the international framework system that we need, or not?
GJ: I’m generally impressed that most governments really do take the commitments they’ve made seriously. And, even, while on a political level, I’ll often hear these kind of culture-war discussions, underneath that, you see the real actions.
Now, the US has obviously swung massively because you had the Trump rowbacks, but then you had, under Biden, the IRA [Inflation Reduction Act], which, by the way, is a very bipartisan programme. I speak to people from the US administration and, just yesterday, [we talked] about the kind of risk of a rowback depending on what happens in November and their view is, of course, there is a very real risk.
But a lot of what the IRA has done has been in red [Republican] states. The Biden officials talk about touring America and meeting all these mayors, Republican mayors and governors in red states, who have seen the benefits of jobs and the industrial regeneration created by it. And so you hope that a lot of that will mean that the underlying programmes survive any political change.
I think in terms of the global picture, we’ve also got to be a bit honest about this. Paris was about 1.5C. I think last year we exceeded 1.5C. Now, climate comes and goes, it’s very important we all recognise that, but, we’ve got to accept that we’re facing an accelerating challenge and we’ve got all the tools to solve it.
I think the place that we really need political leadership now is to be able to look at industries and say: “Look, some industries are going to be the future. And their success is not only going to benefit the climate, it’s going to create more economic opportunity than we lose as we allow some industries to start declining.” And they’ve just got to be brave about this.
I saw that G7 has just agreed to phase-out coal by 2035. [Laughs] I mean, you can be proud to be British on this one, because this is our last coal year, and even then it’s miniscule. The idea that we somehow need these forms of energy for another 11 years is mad. And, so, I’m simultaneously pleased that governments really do take these commitments seriously. But I’m also worried that they fail to grasp the opportunity that a far more rapid change could deliver greater economic growth, greater outcomes for their citizens, than in their current shape.
CB: Obviously, looking at this [Ladybird] book, and looking back over previous decades, I’m interested in your own personal epiphany, if you like, on climate change. What was the thing, that moment…was it a book, TV programme, film, a lecture, a conversation with a colleague or family member, where the penny really dropped and you thought: “OK, climate change is a thing and it’s pretty damn serious”?
GJ: I was a child in the 70s and I joined Greenpeace when I was 15. And the thing that first got me into it was actually local air pollution more than climate. Because back then you could literally see the diesel fumes belching out the back of buses, out of car exhausts, often very visible, and you could really smell and feel it in the air. And I thought it was completely unacceptable, that one person’s choice to drive a car that did that created this huge negative impact on the people behind them.
And you remember that when leaded petrol was banned, which was done almost overnight, it was because of the impact on kids’ brains in dense urban areas with a lot of vehicles. It’s just unconscionable. And I think back then what you could see was that there were clean alternatives. This wasn’t about sackcloth and ashes. It wasn’t asking people to give up the huge benefits of industrial progress. It was just we needed ways to enable people to choose better solutions at the same or lower cost.
And so that was always my philosophy and I think, as I became more and more aware of climate change, exactly the same applied.
Now, I think the real two points of epiphany for me on climate were, first of all, realising there’s a solution. I think for a long time, you kind of feel like, how can we power our society without burning stuff? And then you look at the cost curves for solar and wind and all the other technologies. And, honestly, it’s going to be cheaper to stop burning stuff. That was an amazing moment, when I realised that we didn’t have to arrange the forces for saving the planet against the force of economics, because they actually lined up.
I think the second thing was Al Gore’s movie, An Inconvenient Sequel. We’d actually started this company, we started the company in 2015-16. In 2018, it looked like we were doing quite well. And we went away for a couple of days for a management off-site. And, after a hard day slaving over clipboards or whatever you do, I arranged for everyone to watch a movie and they all came in and I think they thought that we’re going to get something fun. And when An Inconvenient Sequel opened up, all the people in the room, you could see their faces drop, because I was forcing them to watch something worthy.
But you know what, five minutes in, everyone’s WhatsApp messages start pinging, and it was like, “wow, we have to do more”. Because it was showing the very real effects of climate change, which, by the way, are only worse now. And then at the end of the movie it had hope, it ended with a deal on solar for India. And, of course, it was for dramatic effect, but the reality of this is that we do have hope.
After the movie finished, we all just sat down and said how can we accelerate the ability our company has to do something about this? And so, I think, hope is as important, knowing there is a solution, is as important as knowing there’s a problem.
CB: You have talked very confidently about the cost benefits of wind and solar and you mentioned earlier how, a couple of years ago, government auctions made offshore wind look incredibly appealing. And then we had a failed auction and now it looks like quite a different picture. Heat pump installations in the UK are still very slow, costs are high. The cost of electricity versus gas makes them probably cheaper to run, but not definitely. How would you respond to lots of people saying: “Is it actually cheaper? It’s going to be more expensive, we need to consider perhaps using boilers?” How do you respond to those very serious concerns?
GJ: The first thing we’re going to do is recognise that today’s markets don’t reflect the underlying physics and economics, which is why I talk about market reform all the time. The second thing we need to do is recognise that there’s always going be short-term blips, those auction failures were driven simply by short-term inflation and interest rates, both of which were largely the consequence of the gas crisis, i.e, our addiction to fossil fuel is so damaging, it even makes the solutions to fossil fuels more expensive.
And then we talk about things like adoption of heat pumps and so on. A year ago, two years ago, no one had heard of a heat pump. Now, the climate change denying parts of the media have made heat pumps famous. Thank you very much. We’ve got to remember that we’ve got long-term transitions and almost everything we talked about there are short-term issues.
So, if we break it down a bit, we can generate electricity from renewable sources in the UK, for between 4p and 8p a kilowatt hour (kWh). New generation in solar and wind can do that.
Consumers traditionally in the UK have paid 17p/kWh. During the energy crisis our bills were paid for by the government, but they went to 40p/kWh or 50p/kWh, right? I.e. the generating cost, the cost to generate electricity, is way below what people pay. We’ve just got a crazily inefficient system for getting it from generation to consumption. We need to fix that. Which is why that was literally the first set of policies that I talked to you about.
Just by way of example, electricity roughly trebles in price in the UK between the point it’s generated and the point you consume it. Milk, which is much harder to transmit, gets schlepped about in diesel lorries, it has to be bottled and pasteurised, is stored on refrigerated shelves in supermarkets with really expensive real estate. I think milk goes up by 50% between the farm and the point you buy it. Our electricity system is just fundamentally far too inefficient. And we have to fix that. And that’s the market reforms.
But then in terms of, for example, running costs of heat pumps…on a smart tariff they’re almost certainly cheaper for the vast majority of homes than a gas boiler to run. And that’s in today’s crazy world where all of the climate and social levies are sitting on electricity. If you take away that distortion, running heat pumps on electricity is dramatically cheaper than a gas boiler.
We’ve still got to make heat pumps cheaper to buy and install. That’s why, again, going back to first principles, I was inspired here by Michael Dell, of Dell Computers. When he was doing his MBA, he sat in his dorm room and he read an article that said that a $3,000 IBM PC only had $1,000 of components. But, you know, you had an inefficient supply chain, loads of wholesalers and, when you look at heat pumps, it’s just the same. So we’ve started making our own, so we can be a bit like Dell, by going direct to make them cheaper. And already we’re seeing a big cost benefit. But the more we invest, the more we scale up, the more we’ll see that, and other companies are doing the same.
So what we’ve got is a situation where we’re at the beginning of a technology change. And if you look at the first iPhones, they cost £435 and today you would feel like you’re holding a brick that barely performed. But they were enough to kick start the smartphone revolution and that’s just the process we’re going through with the heat pumps.
The UK has very specific needs for heating, not only do we have poorly insulated homes, but we’ve got a very temperate climate. We also heat our homes with wet radiators, whereas most countries that use heat pumps have used air to heat the home. And so we’ve needed to make heat pumps that are UK specific. All of this is happening at the moment and it just gives me huge optimism.
And if I compare this to the alternative, by the way – the idea of, for example, piping hydrogen into people’s homes – I don’t know where to start.
We can start with engineering. Hydrogen is the smallest molecule in the universe. When a rocket launch is delayed by a fuel leak, which they are, that’s hydrogen. Rocket scientists can’t keep it in a very closed and carefully designed system. You know, there are bits of our gas network that are unmapped, that are 100 years old, I think there are bits of the piping that have got wood in them! Anywhere you’ve got a leak, hydrogen can get out. And so, before you can pipe hydrogen [into homes], you’ve got to make sure that every single home, every single inch of every pipe in every home, every valve and every joint, every appliance is going to be able to keep the hydrogen in. And this is unbelievably complex.
I saw the other day a hydrogen cooking hob, with an invisible flame, literally invisible flame. I don’t know why you’d want one of those in your kitchen, so you’ve got an explosive leaky substance with an invisible flame, or you could have an electric induction hob for roughly the same amount. The same cost to run, wipe clean, totally safe, incredibly controllable and you don’t need all this stuff piped into your home.
And that’s just looking at the piping, nevermind where’s the hydrogen coming from! 97% of the hydrogen in the world at the moment is unabated carbon emitting hydrogen. And this is years after we were told we’d be starting to get green hydrogen available. And then, if you’re going to use hydrogen to heat a home, if it’s green hydrogen, you’ve got to create renewable electricity, you then use that to power electrolysers, you then have to compress the hydrogen, pump it into the home and burn it. End-to-end, 40% efficient at turning the electricity you started with into heat. And, meanwhile, the heat pump is end-to-end 250% to 400% efficient.
There we go. I’m very optimistic because all you ever have to do is go back to the physics of this stuff.
Oh sorry, the other thing you mentioned, you know…is electricity more expensive than gas? Well, of course electricity is about three times more expensive per unit, maybe four times with the distorting taxes that need to be taken away. But electricity is so much more efficient. An EV turns 80% of the energy and electricity into motion, a petrol engine is 25%. A heat pump, you get 300% efficiency efficiency, a gas boiler gives you 85%. So electricity is so much more efficient.
And then the real magic with electricity is that it’s fungible. If you’ve got an EV, it can store the electricity at the cheapest times, you can’t do that kind of thing with gas. In fact, increasingly, some EVs can put that energy back into your house at peak times, reducing your energy costs.
Fundamentally, I think there is one thing here which is that electricity puts consumers far more in control. If they choose to, they can get solar panels and largely eliminate their dependence on anyone else. But with fossil fuels, we’re totally dependent on the countries and, to a degree, corporations that provide that molecule. One reason they don’t want to let go is that control gives them power and it gives them money. And we saw that during the gas crisis.
Any comparison of gas costs versus electricity costs has to remember that, from time to time, we experience these fossil fuel crises, because we’re dependent on people in control. And during the worst of the gas crisis, the price of gas went up to 30-fold. There was a very real chance that Europe was not going to have enough gas. In fact, it is potentially the case that we were saved from a gas crisis by a mild winter.
So we should never allow anyone to get away with this idea that electricity is more expensive than gas, because they cherry-pick the times that gas is cheap and they forget about the times that gas or other fossil fuels brutalise our economies. I think it cost the UK £100bn, the government paid two-thirds of our energy bills during the crisis. That’s how bad fossil fuels are.
CB: You’ve talked already about market reform and how important you think it is. One of the key arguments from people who are in favour of this transition that the economy is going through, is that dramatic reform of the electricity markets puts at risk the investments we need to get 2030, 2035 or whatever our targets are, which currently relies on the system as it is today. How do you respond to that?
GJ: It’s just not true. Of course, investors quite rightly, when investors write a large cheque, they are making a huge commitment and they need to know it’s got a good chance of delivering a return. And, so, whenever investors have got comfortable with one way of doing things, they of course want to see that carry on.
But, first of all, there are plenty of other investors available. Whilst in electricity, investors have long had these kind of guaranteed returns through different mechanisms, oil and gas investors make their colossal investments against enormous technology risk, enormous political risk and enormous market risk. When they decide to start extracting or to buy the licences for an oil or gas field and then make a huge investment required to extract the stuff. And then huge investments in LNG tankers and terminals. They have no idea what the future price of oil or gas will be. And they can still make those investments. So you can make massive investments against degrees of uncertainty.
And what we’ve seen already in electricity in the past was, for example, when we moved to the CfD [contracts for difference] regime, from the RO [renewable obligations] or FiTs [feed in tariffs] or whatever. A lot of investors said: “Well, that will kill investment.” It all [still] happened.
Similarly, when we’ve seen, for example, a number of states in the US have introduced dynamic zonal pricing, the investments carried on unaffected. So, at the end of the day, people need electricity. In fact, the demand for electricity is only going to go up. And when there’s demand for a product, you can invest in producing it.
CB: One of the things that Octopus has been quite involved in is the demand flexibility service being run by the electricity system operator. And that’s obviously encouraging customers to cut their use at peak times. How much importance do you put on that kind of system as we transition to a net-zero power system?
GJ: First of all I’d say Octopus was pioneering that for four years before the ESO brilliantly introduced it. Because the sort of legacy energy system said: “Customers won’t do this stuff.” Everything we’d invested in, in trials and experiments with customers showed that they loved that.
It was brilliant the way the ESO introduced it. And Octopus Saving Sessions accounts for 50% of all of the participation. Because we’d nurtured relationships with customers.
These are not energy geeks, by the way. Energy geeks were already on dynamic tariffs and smart tariffs, which meant, actually, it was kind of hard for them to participate in the Saving Sessions, because they were already fully optimised. This was one and a half million for us, one and a half million ordinary households that finally had the opportunity to shop for bargain electricity the way that they already do with supermarkets.
And giving people the opportunity to cut costs, especially in a crisis, but also to have agency, to be able to make decisions, is so critically important. And I think that this isn’t about renewables, this is just about the way the energy system has treated customers as dumb offtakers, rather than them being the very reason we exist. And as soon as we truly embraced customers, we discover all these ways in which we simultaneously provide them with better service and better value through a more efficient system. It’s just the equivalent of supermarkets pricing goods to clear, rather than letting them go off.
I think the big challenge for the energy sector now – and there’s a real risk that legacy thinking kills this – but the real opportunity and challenge is to make this the norm. It shouldn’t be a weird add-on in one winter in a crisis. It’s like every day, there are a bunch of people, turning electric generation on and off. There’s a whole bunch of companies investing heavily in things like batteries. And the ability to shift demand around is just as big, a potential contributor to an efficient system. In fact, it’s better because you don’t have to buy any assets. And so I think we shouldn’t be thinking this has been an add-on system, it is the system.
It’s insanely popular, too, just be really clear. We got 100,000 customers asking for smart meters during that programme just to participate.
CB: The last question neatly segues into this. Technology is a key part of being able to do that, but also your broader pitch to customers. A big part of this transition to EVs requires integrating very well with your technology. But how do you deal with customers that aren’t up to date? Who don’t necessarily have smartphones, who aren’t digitally savvy? How do you ensure that they’re not left behind?
GJ: I tell you what, those customers were being brutalised in the old energy industry. If they’re calling a legacy energy company that has got a 45-minute wait on the phones and then you get through to someone and they can’t help you, because it’s got to be a different department, so they promise to call you back and they don’t call me back, and then they hand me through to another department, and you just do all of the security questions, just as they’re closing the line, that was the experience those people had in energy.
So the first thing is great technology enables you to provide everybody with a better service. Octopus’s magic is that when you phone us up, 95% of the time, the person you are speaking to can sort out your problem there and then, because of technology [which is known as Kraken]. Fewer things go wrong, because of technology.
Second thing is, I’m so sorry, I can’t remember the number, but, actually, there are relatively few people in the UK that don’t have access to a smartphone. And if we think about things like everything from universal credit to the ability to buy an enormous range of products and services, it requires a smartphone. And the most important thing is making sure that wherever someone has got the access, we enable them to become part of an efficient system.
For the very small number of people that don’t have those technologies, it’s very unlikely you’d have an EV and not have a smartphone. And so a lot of the technologies we really need to optimise to make the system efficient for everyone, like EVs, naturally you are going to find the people that have the kit.
So I think the most important thing is you look at everybody, regardless of where they are, but you don’t get held back by saying that everything’s universal, right? After all, Aldi and Lidl, great supermarkets, but we don’t prevent them from rolling out because some people might not be able to get there. In fact, the more they’ve rolled out, the more they’ve been able to become closer to being universally accessible anyway.
You know, things like when the iPhone launched it was £435 plus I think about minimum £35 a month. It was a super premium product. But, within five years, it paved the way to the $50 Android, $20 Android, the ubiquitous Android that has transformed not only the lives of people in wealthy countries, but many developing countries, too.
People who try to hold new technology to the bar of universality are typically protecting some sort of legacy against the technology improvements that benefit consumers and we should not have much patience for that.
For example, someone recently wrote to me because their 700-year old house had a heat pump that didn’t always work efficiently – by the way, I think it was badly installed and we can fix that – but there’s not that many 700-year old houses, and I’d love to serve them. But 20% of households don’t have gas in the UK, so heat pumps are held to this idea that they have got to work for everyone in all situations, which, by the way, they are better than gas because every house has got electricity and only 80% have got gas. So even when we talk about universality, we are usually using it for a false comparison anyway.
CB: Thank you.
GJ: Thank you.

Key developments
Food inflation on the rise
DELUGE STRIKES FOOD: Extreme rainfall and flooding across the Mediterranean and north Africa has “battered the winter growing regions that feed Europe…threatening food price rises”, reported the Financial Times. Western France has “endured more than 36 days of continuous rain”, while farmers’ associations in Spain’s Andalusia estimate that “20% of all production has been lost”, it added. Policy expert David Barmes told the paper that the “latest storms were part of a wider pattern of climate shocks feeding into food price inflation”.

NO BEEF: The UK’s beef farmers, meanwhile, “face a double blow” from climate change as “relentless rain forces them to keep cows indoors”, while last summer’s drought hit hay supplies, said another Financial Times article. At the same time, indoor growers in south England described a 60% increase in electricity standing charges as a “ticking timebomb” that could “force them to raise their prices or stop production, which will further fuel food price inflation”, wrote the Guardian.
‘TINDERBOX’ AND TARIFFS: A study, covered by the Guardian, warned that major extreme weather and other “shocks” could “spark social unrest and even food riots in the UK”. Experts cited “chronic” vulnerabilities, including climate change, low incomes, poor farming policy and “fragile” supply chains that have made the UK’s food system a “tinderbox”. A New York Times explainer noted that while trade could once guard against food supply shocks, barriers such as tariffs and export controls – which are being “increasingly” used by politicians – “can shut off that safety valve”.
El Niño looms
NEW ENSO INDEX: Researchers have developed a new index for calculating El Niño, the large-scale climate pattern that influences global weather and causes “billions in damages by bringing floods to some regions and drought to others”, reported CNN. It added that climate change is making it more difficult for scientists to observe El Niño patterns by warming up the entire ocean. The outlet said that with the new metric, “scientists can now see it earlier and our long-range weather forecasts will be improved for it.”
WARMING WARNING: Meanwhile, the US Climate Prediction Center announced that there is a 60% chance of the current La Niña conditions shifting towards a neutral state over the next few months, with an El Niño likely to follow in late spring, according to Reuters. The Vibes, a Malaysian news outlet, quoted a climate scientist saying: “If the El Niño does materialise, it could possibly push 2026 or 2027 as the warmest year on record, replacing 2024.”
CROP IMPACTS: Reuters noted that neutral conditions lead to “more stable weather and potentially better crop yields”. However, the newswire added, an El Niño state would mean “worsening drought conditions and issues for the next growing season” to Australia. El Niño also “typically brings a poor south-west monsoon to India, including droughts”, reported the Hindu’s Business Line. A 2024 guest post for Carbon Brief explained that El Niño is linked to crop failure in south-eastern Africa and south-east Asia.
News and views
- DAM-AG-ES: Several South Korean farmers filed a lawsuit against the country’s state-owned utility company, “seek[ing] financial compensation for climate-related agricultural damages”, reported United Press International. Meanwhile, a national climate change assessment for the Philippines found that the country “lost up to $219bn in agricultural damages from typhoons, floods and droughts” over 2000-10, according to Eco-Business.
- SCORCHED GRASS: South Africa’s Western Cape province is experiencing “one of the worst droughts in living memory”, which is “scorching grass and killing livestock”, said Reuters. The newswire wrote: “In 2015, a drought almost dried up the taps in the city; farmers say this one has been even more brutal than a decade ago.”
- NOUVELLE VEG: New guidelines published under France’s national food, nutrition and climate strategy “urged” citizens to “limit” their meat consumption, reported Euronews. The delayed strategy comes a month after the US government “upended decades of recommendations by touting consumption of red meat and full-fat dairy”, it noted.
- COURTING DISASTER: India’s top green court accepted the findings of a committee that “found no flaws” in greenlighting the Great Nicobar project that “will lead to the felling of a million trees” and translocating corals, reported Mongabay. The court found “no good ground to interfere”, despite “threats to a globally unique biodiversity hotspot” and Indigenous tribes at risk of displacement by the project, wrote Frontline.
- FISH FALLING: A new study found that fish biomass is “falling by 7.2% from as little as 0.1C of warming per decade”, noted the Guardian. While experts also pointed to the role of overfishing in marine life loss, marine ecologist and study lead author Dr Shahar Chaikin told the outlet: “Our research proves exactly what that biological cost [of warming] looks like underwater.”
- TOO HOT FOR COFFEE: According to new analysis by Climate Central, countries where coffee beans are grown “are becoming too hot to cultivate them”, reported the Guardian. The world’s top five coffee-growing countries faced “57 additional days of coffee-harming heat” annually because of climate change, it added.

Nature talks inch forward
This week, Carbon Brief covers the latest round of negotiations under the UN Convention on Biological Diversity (CBD), which occurred in Rome over 16-19 February.
The penultimate set of biodiversity negotiations before October’s Conference of the Parties ended in Rome last week, leaving plenty of unfinished business.
The CBD’s subsidiary body on implementation (SBI) met in the Italian capital for four days to discuss a range of issues, including biodiversity finance and reviewing progress towards the nature targets agreed under the Kunming-Montreal Global Biodiversity Framework (GBF).
However, many of the major sticking points – particularly around finance – will have to wait until later this summer, leaving some observers worried about the capacity for delegates to get through a packed agenda at COP17.
The SBI, along with the subsidiary body on scientific, technical and technological advice (SBSTTA) will both meet in Nairobi, Kenya, later this summer for a final round of talks before COP17 kicks off in Yerevan, Armenia, on 19 October.
Money talks
Finance for nature has long been a sticking point at negotiations under the CBD.
Discussions on a new fund for biodiversity derailed biodiversity talks in Cali, Colombia, in autumn 2024, requiring resumed talks a few months later.
Despite this, finance was barely on the agenda at the SBI meetings in Rome. Delegates discussed three studies on the relationship between debt sustainability and implementation of nature plans, but the more substantive talks are set to take place at the next SBI meeting in Nairobi.
Several parties “highlighted concerns with the imbalance of work” on finance between these SBI talks and the next ones, reported Earth Negotiations Bulletin (ENB).
Lim Li Ching, senior researcher at Third World Network, noted that tensions around finance permeated every aspect of the talks. She told Carbon Brief:
“If you’re talking about the gender plan of action – if there’s little or no financial resources provided to actually put it into practice and implement it, then it’s [just] paper, right? Same with the reporting requirements and obligations.”
Monitoring and reporting
Closely linked to the issue of finance is the obligations of parties to report on their progress towards the goals and targets of the GBF.
Parties do so through the submission of national reports.
Several parties at the talks pointed to a lack of timely funding for driving delays in their reporting, according to ENB.
A note released by the CBD Secretariat in December said that no parties had submitted their national reports yet; by the time of the SBI meetings, only the EU had. It further noted that just 58 parties had submitted their national biodiversity plans, which were initially meant to be published by COP16, in October 2024.
Linda Krueger, director of biodiversity and infrastructure policy at the environmental not-for-profit Nature Conservancy, told Carbon Brief that despite the sparse submissions, parties are “very focused on the national report preparation”. She added:
“Everybody wants to be able to show that we’re on the path and that there still is a pathway to getting to 2030 that’s positive and largely in the right direction.”
Watch, read, listen
NET LOSS: Nigeria’s marine life is being “threatened” by “ghost gear” – nets and other fishing equipment discarded in the ocean – said Dialogue Earth.
COMEBACK CAUSALITY: A Vox long-read looked at whether Costa Rica’s “payments for ecosystem services” programme helped the country turn a corner on deforestation.
HOMEGROWN GOALS: A Straits Times podcast discussed whether import-dependent Singapore can afford to shelve its goal to produce 30% of its food locally by 2030.
‘RUSTING’ RIVERS: The Financial Times took a closer look at a “strange new force blighting the [Arctic] landscape”: rivers turning rust-orange due to global warming.

Dangerous heat for Tour de France riders only a ‘question of time’
Rising temperatures across France since the mid-1970s is putting Tour de France competitors at “high risk”, according to new research.
The study, published in Scientific Reports, uses 50 years of climate data to calculate the potential heat stress that athletes have been exposed to across a dozen different locations during the world-famous cycling race.
The researchers find that both the severity and frequency of high-heat-stress events have increased across France over recent decades.
But, despite record-setting heatwaves in France, the heat-stress threshold for safe competition has rarely been breached in any particular city on the day the Tour passed through.
(This threshold was set out by cycling’s international governing body in 2024.)
However, the researchers add it is “only a question of time” until this occurs as average temperatures in France continue to rise.
The lead author of the study tells Carbon Brief that, while the race organisers have been fortunate to avoid major heat stress on race days so far, it will be “harder and harder to be lucky” as extreme heat becomes more common.
‘Iconic’
The Tour de France is one of the world’s most storied cycling races and the oldest of Europe’s three major multi-week cycling competitions, or Grand Tours.
Riders cover around 3,500 kilometres (km) of distance and gain up to nearly 55km of altitude over 21 stages, with only two or three rest days throughout the gruelling race.
The researchers selected the Tour de France because it is the “iconic bike race. It is the bike race of bike races,” says Dr Ivana Cvijanovic, a climate scientist at the French National Research Institute for Sustainable Development, who led the new work.
Heat has become a growing problem for the competition in recent years.
In 2022, Alexis Vuillermoz, a French competitor, collapsed at the finish line of the Tour’s ninth stage, leaving in an ambulance and subsequently pulling out of the race entirely.
Two years later, British cyclist Sir Mark Cavendish vomited on his bike during the first stage of the race after struggling with the 36C heat.
The Tour also makes a good case study because it is almost entirely held during the month of July and, while the route itself changes, there are many cities and stages that are repeated from year to year, Cvijanovic adds.
‘Have to be lucky’
The study focuses on the 50-year span between 1974 and 2023.
The researchers select six locations across the country that have commonly hosted the Tour, from the mountain pass of Col du Tourmalet, in the French Pyrenees, to the city of Paris – where the race finishes, along the Champs-Élysées.
These sites represent a broad range of climatic zones: Alpe d’ Huez, Bourdeaux, Col du Tourmalet, Nîmes, Paris and Toulouse.
For each location, they use meteorological reanalysis data from ERA5 and radiant temperature data from ERA5-HEAT to calculate the “wet-bulb globe temperature” (WBGT) for multiple times of day across the month of July each year.
WBGT is a heat-stress index that takes into account temperature, humidity, wind speed and direct sunlight.
Although there is “no exact scientific consensus” on the best heat-stress index to use, WBGT is “one of the rare indicators that has been originally developed based on the actual human response to heat”, Cvijanovic explains.
It is also the one that the International Cycling Union (UCI) – the world governing body for sport cycling – uses to assess risk. A WBGT of 28C or higher is classified as “high risk” by the group.
WBGT is the “gold standard” for assessing heat stress, says Dr Jessica Murfree, director of the ACCESS Research Laboratory and assistant professor at the University of North Carolina at Chapel Hill.
Murfree, who was not involved in the new study, adds that the researchers are “doing the right things by conducting their science in alignment with the business practices that are already happening”.
The researchers find that across the 50-year time period, WBGT has been increasing across the entire country – albeit, at different rates. In the north-west of the country, WBGT has increased at an average rate of 0.1C per decade, while in the southern and eastern parts of the country, it has increased by more than 0.5C per decade.
The maps below show the maximum July WBGT for each decade of the analysis (rows) and for hourly increments of the late afternoon (columns). Lower temperatures are shown in lighter greens and yellows, while higher temperatures are shown in darker reds and purples.
Six Tour de France locations analysed in the study are shown as triangles on the maps (clockwise from top): Paris, Alpe d’ Huez, Nîmes, Toulouse, Col du Tourmalet and Bordeaux.
The maps show that the maximum WBGT temperature in the afternoon has surpassed 28C over almost the entire country in the last decade. The notable exceptions to this are the mountainous regions of the Alps and the Pyrenees.
The researchers also find that most of the country has crossed the 28C WBGT threshold – which they describe as “dangerous heat levels” – on at least one July day over the past decade. However, by looking at the WBGT on the day the Tour passed through any of these six locations, they find that the threshold has rarely been breached during the race itself.
For example, the research notes that, since 1974, Paris has seen a WBGT of 28C five times at 3pm in July – but that these events have “so far” not coincided with the cycling race.
The study states that it is “fortunate” that the Tour has so far avoided the worst of the heat-stress.
Cvijanovic says the organisers and competitors have been “lucky” to date. She adds:
“It has worked really well for them so far. But as the frequency of these [extreme heat] events is increasing, it will be harder and harder to be lucky.”
Dr Madeleine Orr, an assistant professor of sport ecology at the University of Toronto who was not involved in the study, tells Carbon Brief that the paper was “really well done”, noting that its “methods are good [and its] approach was sound”. She adds:
“[The Tour has] had athletes complain about [the heat]. They’ve had athletes collapse – and still those aren’t the worst conditions. I think that that says a lot about what we consider safe. They’ve still been lucky to not see what unsafe looks like, despite [the heat] having already had impacts.”
Heat safety protocols
In 2024, the UCI set out its first-ever high temperature protocol – a set of guidelines for race organisers to assess athletes’ risk of heat stress.
The assessment places the potential risk into one of five categories based on the WBGT, ranging from very low to high risk.
The protocol then sets out suggested actions to take in the event of extreme heat, ranging from having athletes complete their warm-ups using ice vests and cold towels to increasing the number of support vehicles providing water and ice.
If the WBGT climbs above the 28C mark, the protocol suggests that organisers modify the start time of the stage, adapt the course to remove particularly hazardous sections – or even cancel the race entirely.
However, Orr notes that many other parts of the race, such as spectator comfort and equipment functioning, may have lower temperatures thresholds that are not accounted for in the protocol, but should also be considered.
Murfree points out that the study’s findings – and the heat protocol itself – are “really focused on adaptation, rather than mitigation”. While this is “to be expected”, she tells Carbon Brief:
“Moving to earlier start times or adjusting the route specifically to avoid these locations that score higher in heat stress doesn’t stop the heat stress. These aren’t climate preventative measures. That, I think, would be a much more difficult conversation to have in the research because of the Tour de France’s intimate relationship with fossil-fuel companies.”

DeBriefed 20 February 2026: EU’s ‘3C’ warning | Endangerment repeal’s impact on US emissions | ‘Tree invasion’ fuelled South America’s fires
Welcome to Carbon Brief’s DeBriefed.
An essential guide to the week’s key developments relating to climate change.
This week
Preparing for 3C
NEW ALERT: The EU’s climate advisory board urged countries to prepare for 3C of global warming, reported the Guardian. The outlet quoted Maarten van Aalst, a member of the advisory board, saying that adapting to this future is a “daunting task, but, at the same time, quite a doable task”. The board recommended the creation of “climate risk assessments and investments in protective measures”.
‘INSUFFICIENT’ ACTION: EFE Verde added that the advisory board said that the EU’s adaptation efforts were so far “insufficient, fragmented and reactive” and “belated”. Climate impacts are expected to weaken the bloc’s productivity, put pressure on public budgets and increase security risks, it added.
UNDERWATER: Meanwhile, France faced “unprecedented” flooding this week, reported Le Monde. The flooding has inundated houses, streets and fields and forced the evacuation of around 2,000 people, according to the outlet. The Guardian quoted Monique Barbut, minister for the ecological transition, saying: “People who follow climate issues have been warning us for a long time that events like this will happen more often…In fact, tomorrow has arrived.”
IEA ‘erases’ climate
MISSING PRIORITY: The US has “succeeded” in removing climate change from the main priorities of the International Energy Agency (IEA) during a “tense ministerial meeting” in Paris, reported Politico. It noted that climate change is not listed among the agency’s priorities in the “chair’s summary” released at the end of the two-day summit.
US INTERVENTION: Bloomberg said the meeting marked the first time in nine years the IEA failed to release a communique setting out a unified position on issues – opting instead for the chair’s summary. This came after US energy secretary Chris Wright gave the organisation a one-year deadline to “scrap its support of goals to reduce energy emissions to net-zero” – or risk losing the US as a member, according to Reuters.
Around the world
- ISLAND OBJECTION: The US is pressuring Vanuatu to withdraw a draft resolution supporting an International Court of Justice ruling on climate change, according to Al Jazeera.
- GREENLAND HEAT: The Associated Press reported that Greenland’s capital Nuuk had its hottest January since records began 109 years ago.
- CHINA PRIORITIES: China’s Energy Administration set out its five energy priorities for 2026-2030, including developing a renewable energy plan, said International Energy Net.
- AMAZON REPRIEVE: Deforestation in the Brazilian Amazon has continued to fall into early 2026, extending a downward trend, according to the latest satellite data covered by Mongabay.
- GEZANI DESTRUCTION: Reuters reported the aftermath of the Gezani cyclone, which ripped through Madagascar last week, leaving 59 dead and more than 16,000 displaced people.

Captured

Repealing the US’s landmark “endangerment finding”, along with actions that rely on that finding, will slow the pace of US emissions cuts, according to Rhodium Group visualised by Carbon Brief. US president Donald Trump last week formally repealed the scientific finding that underpins federal regulations on greenhouse gas emissions, although the move is likely to face legal challenges. Data from the Rhodium Group, an independent research firm, shows that US emissions will drop more slowly without climate regulations. However, even with climate regulations, emissions are expected to drop much slower under Trump than under the previous Joe Biden administration, according to the analysis.

How a ‘tree invasion’ helped to fuel South America’s fires
This week, Carbon Brief explores how the “invasion” of non-native tree species helped to fan the flames of forest fires in Argentina and Chile earlier this year.
Since early January, Chile and Argentina have faced large-scale and deadly wildfires, including in Patagonia, which spans both countries.
These fires have been described as “some of the most significant and damaging in the region”, according to a World Weather Attribution (WWA) analysis covered by Carbon Brief.
In both countries, the fires destroyed vast areas of native forests and grasslands, displacing thousands of people. In Chile, the fires resulted in 23 deaths.

Multiple drivers contributed to the spread of the fires, including extended periods of high temperatures, low rainfall and abundant dry vegetation.
The WWA analysis concluded that human-caused climate change made these weather conditions at least three times more likely.
According to the researchers, another contributing factor was the invasion of non-native trees in the regions where the fires occurred.
The risk of non-native forests
In Argentina, the wildfires began on 6 January and persisted until the first week of February. They hit the city of Puerto Patriada and the Los Alerces and Lago Puelo national parks, in the Chubut province, as well as nearby regions.
In these areas, more than 45,000 hectares of native forests – such as Patagonian alerce tree, myrtle, coigüe and ñire – along with scrubland and grasslands, were consumed by the flames, according to the WWA study.
In Chile, forest fires occurred from 17 to 19 January in the Biobío, Ñuble and Araucanía regions.
The fires destroyed more than 40,000 hectares of forest and more than 20,000 hectares of non-native forest plantations, including eucalyptus and Monterey pine.
Dr Javier Grosfeld, a researcher at Argentina’s National Scientific and Technical Research Council (CONICET) in northern Patagonia, told Carbon Brief that these species, introduced to Patagonia for production purposes in the late 20th century, grow quickly and are highly flammable.
Because of this, their presence played a role in helping the fires to spread more quickly and grow larger.
However, that is no reason to “demonise” them, he stressed.
Forest management
For Grosfeld, the problem in northern Patagonia, Argentina, is a significant deficit in the management of forests and forest plantations.
This management should include pruning branches from their base and controlling the spread of non-native species, he added.
A similar situation is happening in Chile, where management of pine and eucalyptus plantations is not regulated. This means there are no “firebreaks” – gaps in vegetation – in place to prevent fire spread, Dr Gabriela Azócar, a researcher at the University of Chile’s Centre for Climate and Resilience Research (CR2), told Carbon Brief.
She noted that, although Mapuche Indigenous communities in central-south Chile are knowledgeable about native species and manage their forests, their insight and participation are not recognised in the country’s fire management and prevention policies.
Grosfeld stated:
“We are seeing the transformation of the Patagonian landscape from forest to scrubland in recent years. There is a lack of preventive forestry measures, as well as prevention and evacuation plans.”
