After years of planning, the Tropical Forests Forever Facility has so far failed to take root.

In selecting a location for this year’s United Nations climate conference, host country Brazil chose symbolism over sense. Belém, the site of this year’s summit, is perched on the edge of the Amazon rainforest. The setting is meant to foreground the importance of nature in fighting climate change — despite the city’s desperately inadequate infrastructure for housing the tens of thousands of attendees the conference draws.
That mismatch of intention and resources has also played out in the meeting rooms of the gathering, known as COP30. The centerpiece of President Luiz Inácio Lula da Silva’s agenda was meant to be the Tropical Forests Forever Facility, an international finance scheme to raise at least $2 billion per year to fund forest conservation and restoration. After an inauspicious launch in which presumed supporters of the facility failed to put up any actual financing, however, it’s unclear whether the TFFF will have a chance to prove it can work.
Deforestation rates have hardly budged globally since 2021, despite more than 100 countries signing a pledge that year to halt and reverse deforestation and land degradation within the decade. The world lost more than 8 million hectares of forest to deforestation last year, causing the release of more than 4 billion metric tons of carbon dioxide into the atmosphere — nearly as much as the entire U.S. energy sector.
First proposed by the Brazilian government in Dubai at COP28, the TFFF was devised to deliver a more consistent source of funding to countries in the global south for forest conservation that would not depend on foreign aid budgets or be vulnerable to the ups and downs of the carbon market.
The plan involves setting up a fund with money borrowed from wealthier countries and private investors at low interest rates and invested in publicly traded bonds from emerging markets and developing economies that command higher interest rates. After paying back investors, the revenue generated by the spread — roughly a 3% return, if all goes to plan — would be paid out in annual lump sums to developing countries that have managed to keep deforestation at bay. Participating countries would have the right to spend the proceeds as they choose, so long as the money goes to support forests. At least 20% of the funds would also have to be set aside for indigenous peoples.
Brazil lined up substantial support for the idea ahead of this year’s launch. Six potential investor countries — France, Germany, Norway, the United Arab Emirates, the United Kingdom, and the United States — as well as five potential beneficiaries — Colombia, the Democratic Republic of Congo, Ghana, Indonesia, and Malaysia — joined a steering committee to help shape the development of the fund. The Brazilian government ultimately proposed a fundraising target of $25 billion from the sponsor countries, with the idea to attract about $100 billion from private investors, for a total of $125 billion to get the fund off the ground.
Once the fund started generating revenue, private investors would be paid out first, sponsor countries second, and forested countries last, with the $25 billion serving as insurance to the private investors should the emerging market bond issuers default on their payments. The fund itself would be managed by the World Bank, while a separate entity would govern payments made to forested countries.
While many in the international environmental community were enthusiastic about the plan — especially as a shift away from controversial carbon markets — some raised alarms.
Max Alexander Matthey, a German economics PhD student studying international finance, first saw a presentation on TFFF at COP29 and was baffled by its simplicity. “If it was that easy to make this 3% on borrowed money, why wouldn’t everyone else be doing it?” he recalled thinking at the time. After digging into the Brazilian government’s financial analysis and doing some of his own, Matthey came to believe that the fund’s proponents had underestimated the risk inherent to the investment strategy, as well as the cost of managing the $125 billion fund, he told me.
The whole reason these emerging market bonds command a higher interest rate, Matthey explained, is because they are riskier. If and when countries default on their debts, whether due to global financial shocks like pandemics or wars, or simple mismanagement, the “free money” available for forests will dry up. “These 3% are not up for grabs,” he told me. “They compensate for actual risk and defaults that will happen over time.”
The TFFF was designed to create an incentive for countries with tropical forests to invest in policies and programs to protect forests — to hire rangers to prevent illegal deforestation, to pay farmers not to raze their forests, to implement fire prevention strategies. “They have to heavily invest,” Matthey told me. “If we as the Global North say, Well, thanks for investing large shares of your budget into rainforest protection, but you won’t get any money from our side because financial markets turned the wrong way, that’s just not how you build trust.”
Matthey outlined his analysis in a Substack post in September with University of Calgary economist Aidan Hollis. They found that the JP Morgan EMBI index, which tracks emerging market sovereign bonds, has seen regular downturns of between 18 and 32 percentage points over the past two decades. In the case of the TFFF, a single 20-point loss would wipe out the $25 billion in sponsor debt “and halt rainforest flows, possibly before they even begin,” they wrote.
The energy research firm BloombergNEF seems to agree. In a report published last week outlining the state of international biodiversity finance ahead of COP30, BNEF forecast there would be “little progress” on the TFFF. “The 3% spread is not a money faucet, but a risk premium; studies on the TFFF appear not to have properly conducted risk analyses,” the report said, warning that in effect, the scheme would eat up development finance just to absorb private investor losses. (After this article’s publication, a representative from the World Wildlife Fund reached out to Heatmap to say that this analysis was based on earlier financial modeling, and that a new model had been released in October.)
Just prior to that report’s release, confidence in the TFFF appeared to dip. Brazil’s finance minister lowered his fundraising ambition for the facility to $10 billion by 2026. A few days later, on the eve of the launch, Bloomberg News reported that the United Kingdom would not be contributing to the fund after the country’s treasury department warned it could not afford the investment, despite its significant involvement in the fund’s design.
Following the launch, Indonesia and Portugal each committed $1 billion, while Norway pledged $3 billion, although only if the fund successfully secures at least $10 billion. France also promised €500 million, or just over half a billion dollars, while Germany said it would contribute “significantly,” although it hasn’t said how much yet. All in all, countries committed just $5.5 billion above Brazil’s own initial $1 billion commitment — with at least $3 billion of that contingent on further fundraising.
Andrew Deutz, the managing director for global policy and partnerships at the World Wildlife Fund, which has also been heavily involved in developing the TFFF, assured me this was not the disappointment it appeared to be.
"I look at what just happened last week as validation that the model can work and that countries have confidence in it,” Deutz said. He pointed to the fact that 53 countries, including 19 potential investors, have endorsed the scheme. “A bunch of sponsor countries who haven’t been that engaged said, We like this idea, and I think that creates the opportunity and the momentum that we can get one or two more rounds of capitalization at least.” Deutz was bullish that Germany would come to the table with a pledge between $1 billion and $3 billion, and that the UK would “get guilted in” shortly. He expects to see additional pledges at the World Bank’s Spring Meetings next April, and a few more at the UN General Assembly next September.
As for criticisms of the fund’s investment strategy, he brushed them off, arguing that the risk was "quantifiable and manageable.” He has faith in the TFFF’s modeling showing that the fund’s managers will be able to earn high enough returns to pay back investors and still generate enough funds to pay tropical forest countries.
Charles Barber, the director of natural resources governance and policy at the World Resources Institute was more cautious on both fronts. “We’re glad it’s got as far as it has, but there’s a whole lot of questions that will need to be answered to really get it up,” he told me. Barber saw arguments both for and against the risky investment strategy, but he was skeptical that a starting point of $10 billion would be enough to attract sufficient private investment or give tropical forest countries enough of an incentive to participate.
Matthey has called the idea of a scaled-down TFFF a “worst-case scenario for everyone involved,” due to the high fixed costs of managing the fund, monitoring deforestation, administering the proceeds, etc. The potential payouts to forested countries would be so diminished as to amount to a “rounding error” rather than a true incentive, he wrote.
Deutz told me the TFFF’s architects always expected there to be a three- to four-year ramp-up period. If the fund gets one or two more rounds of capitalization, “we’ll see if it works — and then, assuming it works, you can keep adding to it,” he said. “This is something new and different, so it might take us a little while to prove it out and for people to get comfortable.”

Two new reports out this week create a seemingly contradictory portrait of the country’s energy transition progress.
Two clean energy reports out this week offer seemingly contradictory snapshots of domestic solar and battery manufacturing. One, released Wednesday by the Rhodium Group’s Clean Investment Monitor, shows a distinct decline in investment going into U.S. factories to make more of these technologies. The other, released today by the trade group American Clean Power Association, shows staggering recent growth in production capacity.
So which is it? Is U.S. clean energy manufacturing booming or busting?
Maybe both.
The U.S. is suddenly producing more solar and batteries than ever before — enough to meet current domestic demand — so it makes sense that investment in new factories is starting to slow. At the same time, there’s a lot of room for growth in producing the upstream components that go into these technologies, but the U.S. is no longer as attractive a place to set up shop as it was over the past four years.
The U.S. saw 30 new utility-scale solar factories and 30 new battery factories come online last year alone, according to ACP. The country now has the capacity to meet average domestic demand for storage systems through 2030, and can produce enough solar panels to satisfy demand two times over.
In both industries, nearly all of that capacity has been added since 2022, when the Inflation Reduction Act created new subsidies for domestic manufacturing. The advanced manufacturing production tax credit incentivized not just solar and battery factories, but also all the production of components that go into these technologies, including solar and battery cells, polysilicon, wafers, and anodes. On top of these direct subsidies, the IRA generated demand for U.S.-made products by granting bonus tax credits for utility-scale solar and battery projects built with domestically produced parts.
“The policy definitely laid the right foundation for a lot of this investment to take place,” John Hensley, ACP’s senior vice president of markets and policy analysis, told me.
Trump’s One Big Beautiful Bill Act has changed the environment, however. The utility-scale wind and solar tax credits were supposed to apply through at least 2033, but now projects have to start construction by July 4, 2026 — just over a month from now — in order to claim them. Any of those projects that got started this year will also have to adhere to complex new sourcing rules prohibiting Chinese-made materials.
Now, dollars flowing into new U.S. solar factories appears to be on the decline. Investment fell 22% between the fourth quarter of last year and the first of 2026. Battery manufacturing investment dropped by 16%.
The reason investment is declining is not entirely because of OBBBA — it’s partly a function of the fact that a lot of the projects announced immediately after the IRA passed are entering operations, Hannah Hess, director of climate and energy at the Rhodium Group, told me.
Rhodium’s Clean Investment Monitor tracks two metrics, announcements and investment. Announcements are when a company says it’s building a new factory or expanding an existing one, usually with some kind of projected cost. Investments are an estimate of the actual dollars spent during a given quarter on facility construction, calculated based on the total project budget and the expected amount of time it will take to complete after breaking ground.
According to Rhodium’s data, the peak period for new solar manufacturing project announcements was the second half of 2022 through the first quarter of 2025. During that time, announcements averaged more than $2 billion per quarter. New solar factories announced this past quarter, by contrast, fell to about $350 million.
Since it can take a while to get steel in the ground, the peak period for investment was slightly later, with $13.5 billion invested between the second quarter of 2023 and the third quarter of 2025.
“What we were seeing in that post-IRA period was huge, almost unconstrained growth in that sector, and that’s not happening anymore,” Hess said.
Most of this growth occurred all the way downstream, at the final product assembly level — i.e. factories making solar and battery modules that still had to import many of the components that went into them. This was the “lowest hanging fruit” to bring to the U.S., Hensley, of ACP, told me, as the final assembly is the least technologically challenging part of the supply chain.
“These supply chains have momentum as they get going,” he said, “so as you establish those far downstream component manufacturing, you start to recruit all of the upstream manufacturing.” In other words, a solar cell manufacturer is far more likely to build in the U.S. if there’s a robust local market of module factories to buy the cells.
There’s evidence that’s still happening in spite of changes to the tax credit structure. The ACP report says that three solar cell factories came online between 2024 and today — one per year. If all of the additional factories that have been announced are built by 2030, the U.S. will have nearly enough capacity to meet all of its own demand for solar with domestic cells. Battery cell capacity is growing even faster, with three factories as of the end of 2025 and seven more expected to be complete by the end of this year, which will produce more than enough units to meet average annual demand.
It’s the next step up on the supply chain that spells trouble. For solar, that’s ingots and wafers, followed by polysilicon. Today, the only producer of ingots and wafers in the U.S. is a company called Corning. It produces enough to meet about 25% of current domestic solar cell production, but cell production will more than quadruple by the end of this year compared to last year, according to ACP. Similarly, we produce enough polysilicon to meet Corning’s current needs, but not enough to meet anticipated cell demand. The announced projects in the pipeline will not add much on either front.
For batteries, it’s the anodes and cathodes. There’s currently one factory in California producing cathodes and at least one more under construction, but as there is nothing else in the pipeline, the ACP report expects cell manufacturers to rely on imported cathodes for the foreseeable future. Anodes are the one bright spot — there’s one factory producing what’s known as active anode material factory in the U.S., and four more anticipated by the end of this year. Together, they have the potential to meet demand by 2028, according to ACP.
The question now is whether that snowball effect kicked off by the IRA will continue. “A lot has changed about the outlook for future demand after the One Big Beautiful Bill Act passed,” Hess said. “We have seen some more project cancellations and pauses in construction recently.”
Most recently, a company called Maxeon Solar Technologies canceled a $1 billion cell and module factory in New Mexico. The company had been “fighting for its life” since 2024, according to Canary Media. It’s also majority owned by a Chinese state-owned company. The
OBBBA was likely the nail in the coffin, as it penalizes solar developers who source panels from companies with Chinese ownership.
OBBBA also shortened the timeline for the wind and solar tax credits, while the Trump administration’s hostility to wind and solar permitting has made it more difficult for projects to get built before the credits expire. Hensley said the Trump administration’s hostility toward clean energy has added a lot of risk into the system, complicating final investment decisions for manufacturers.
On the flip side, tariffs have the potential to help some domestic producers. Duties on imports from countries such as Cambodia, India, and Vietnam, all major manufacturers of solar panels, “have made their exports to the U.S. almost prohibitive,” Lara Hayim, the head of solar research at BloombergNEF, told me in an email. “This sort of policy framework could continue to provide some protection for domestic manufacturers,” she said, but there are still plenty of countries with low enough tariffs that they will continue to serve the U.S. and compete with domestic manufacturers.
Hensley said that the Trump administration’s tariffs were a double edged sword. They can help domestic manufacturers, but not if they make all of the inputs into the product more expensive.
“That’s a problem with these blanket type of tariffs that aren’t really fine-tuned to target the behavior that you’d like to see,” he told me. “I think we’re seeing a lot of that push and pull and tension in the system at the moment.”
Between Trump’s tariffs and the OBBBA, there’s no doubt that the manufacturing boom sparked by the IRA is slowing. But Hensley is optimistic that the progress will continue. “We haven’t attracted all of the supply chain yet. It’s still a work in progress, but so far the signs are quite good.”
This week’s conversation is with Duncan Campbell of DER Task Force and it’s about a big question: What makes a socially responsible data center? Campbell’s expansive background and recent focus on this issue made me take note when he recently asked that question on X. Instead of popping up in his replies, I asked him to join me here in The Fight. So shall we get started?
Oh, as always, the following conversation was lightly edited for clarity.
Alright let’s start with the big question: What is a socially responsible data center?
So first, there’s water, which I think is pretty solvable.
Part of me thinks water is not even the right thing to be focusing on necessarily, and it’s surprising that it became at least for a while the center of the controversy around data centers.
I think there’s energy, which is mostly a don’t-raise-people’s-bills kind of thing. Or in extreme cases, actually reducing people’s access to energy.”
I think air pollution is another key. This is one of the biggest own-goals our [climate] space is making, because people are installing behind-the-meter power and we can talk about why they’re doing that, the shifting reasons, but the real shame in it is you really shouldn’t have to run those 24/7. If you’re building your own power plant, it should enable you to get a grid connection, because you’re bringing your own capacity and they can provide you firm service, and you should only have to run that gas plant 1% of the year, so air pollution is a non-issue. If only the grid and its institutions could get their act together, this is a no-brainer. But instead people run them 24/7.
There’s noise, which has been very misunderstood and bungled on a handful of well-known projects. That’s just a do-good engineering and site layout type of problem.
And then there’s other. Beyond the very concrete impacts of a data center, what else can it do for the community it's siting itself in? That’s going to be specific for every community.
There’s going to be a perspective that data centers are takers. They get tax incentives. They’re this big new thing. If data centers were to bring something compelling when [they’re] siting in communities, and it is specific to whatever they’re dealing with, maybe they’d be considered socially responsible.
I don’t think I have the master answer here. Everyone’s trying to figure it out.”
What do you hear from other folks in decarb and climate spaces when you ask this question? Do you hear people come up with solutions, or do they knock down the entire premise of the question — that there isn’t such a thing as a socially responsible data center?
You get both. You definitely get both. It depends on who you're talking to.
I can understand both sides of the equation here. There’s definitely solutions, first of all. I do think there’s a group of people whether it is in the energy world or the data center world or tech who would have this incredulous disbelief that anyone could not want what they’re doing. And that then, after being poked and prodded enough, transforms into a very elitist, almost pejorative explanation of everybody’s just NIMBYs.
I think that’s really unproductive. It kind of just throws gas on the fire.
But there’s a lot of people working on solutions, too. The non-firm grid service thing is just a huge opportunity. To be able to connect these sites to the grid in such a manner they either get curtailed some small amount of hours per year or they show up with accredited capacity, absolving them from curtailing. I mean, we can do that. It’s very doable.
The second question becomes, what are the forms of accredited capacity that can be deployed quickly? I think that’s where there’s a lot of cool stuff around VPPs and such. Sure, build a gas power plant, run it once or twice a year. If anything that’s good for a community — back-up power at grid scale.
There’s also other solutions. A really cool effort right now, former Tesla people building a purely solar and battery DC microgrid in New Mexico.
And there’s also a lot of inertia. The folks making decisions about data centers have been doing stuff a certain way for 20 years and it’s hard to change. The inertia within the culture combined with the enormous pressure to deploy just makes it less dynamic than one would hope.
On my end, I’ve been grappling with the issue of tax revenue. We’re seeing a declining amount of money for social services, things that can really help people for both personal and academic reasons. There's quite a bit a lot of people could say on that topic. At the same time, this is another form of industrial development. People are upset at the amount of resources going to this specific thing.
So when it comes to the data center boom in general, where do you stand on social cost-versus-benefit analysis?
That’s a good question. I’m not an expert. I’m mostly just someone who designs energy projects. But I can say where I’m at personally.
Yeah, but isn’t everyone in the energy space talking about data centers? Shouldn’t we all be thinking about this?
Of course. I’m not in a place to proclaim what is right but I’ll tell you where I’m at right now.
With any large-scale industrial build out it is tough relative to other technological changes that were simpler at the infrastructure layer. Like, the smartphone. Massive technological change but pretty straightforward in a lot of ways. But industrial buildout stresses real physical resources, so people have much more of an opinion of whether it’s worth it or not.
I’m pretty optimistic about AI generally. It’s very hand-wave-y. It’s hard to cite data or anything, because we’re talking about something that hasn’t happened yet, but I’m very optimistic about increasing the amount of intelligence we have access to per person on Earth.
A similar thing I think about is when everyone stopped getting lead poisoning all the time, we all jumped five IQ points and killed each other less. Intelligence is good. A lot of our story as a species is about increasing intelligence and learnings-per-person so we can do more. The idea that we would be able to synthesize it, operate it as a machine outside of our own bodies. It feels pretty inevitable.
There’s questions about what that [AI] will do to the economy and jobs, which is what people are really concerned about and is the case with any major technological change.
Are data centers being deployed at a rate and in a way that is responsible? Like, does it need to be this fast? That’s a question people ask and that’s in a way the question being posed by the moratoriums. They’re not saying let’s ban this forever. They’re saying, let’s take a breather. And I do understand that.
There’s a lot of good solutions that could just be pursued and it’s hard for me to separate my feelings about the current path data centers are taking from what I think is objectively right. We could just be doing way better.
On the energy front, what do you make of the way our energy mix — carbon versus renewables, our resilience — is headed? And where do you think we’re heading in five years?
For the energy and climate world, this is the real question. Data centers are a complicated thing but at the end of the day, for us, they’re a source of electricity demand.
From an electricity perspective, there’s been no growth for 20 years. So the theory of addressing climate change was, as the old stuff breaks we’ll replace it with new clean stuff. That was what we were doing, while saying, a lot of the old stuff we’ll keep around. We’ll layer on the new clean stuff.
It was always the case though that we could enter a new phase of electricity growth. Actually, five years ago, when the phrase “electrify everything” was coined, it explicitly became our goal! We were going to massively and rapidly grow the electricity system in order to switch industry, heating, and transport off of fossil fuels. That’s the right prescription, the right way to do it.
My understanding of it is that while this feels really big, because we haven’t grown in so long, compared to the challenge we were all talking about doing is not big at all. It increases the challenge by 15% or 20%. That’s meaningful. But it just seems like we should be able to do this.
From a climate perspective, as someone who’s been trying to do everything I can on it for a while now, I can’t help but feel a little dismayed that today the growth we’re experiencing is some tiny, tiny percentage of what we actually set out to do. And it’s causing chaos. We’re institutionally falling apart from a single percent of what our goals should be.
This is the time for the electrification case. We can all demonstrate this is possible over the next few years. I think confidence in the electricity system as our energy path can remain high. Or this utterly fails, where it’s really hard to imagine governments and businesses making any sincere attempt at a high electrification pathway.
Plus the week’s biggest development fights.
1. LaPorte County, Indiana — If you’re wondering where data centers are still being embraced in the U.S., look no further than the northwest Indiana city of LaPorte.
2. Cumberland County, New Jersey — A broader splashback against AI infrastructure is building in South Jersey.
3. Washington County, Oregon — Hillsboro, a data center hub in Oregon, is turning to a moratorium.
4. Champaign County, Ohio — We’re still watching the slow downfall of solar in Ohio and there’s no sign of it getting any better.
5. Essex County, New York — Man oh man, what’s going on with battery storage in rural pockets of the Empire State?
