It’s been a tumultuous year for climate politics — and for climate nonprofits. The longtime activist group 350.org suspended its operations in the U.S. (at least temporarily), and Bill Gates, the world’s No. 1 climate funder, declared that the decarbonization movement should make a “strategic pivot” to poverty reduction. How should someone who wants to help the global climate navigate this moment?

Our guest has recommendations. On this week’s episode of Shift Key, Rob talks to Dan Stein, the founder and executive director of Giving Green. Giving Green is a nonprofit that researches the most high-impact climate groups and helps people and companies donate to them. Stein talked about the top five climate groups Giving Green recommends this year, effective altruism and the future of climate philanthropy, and whether Bill Gates is right that climate activism has focused too much on emissions targets.

Shift Key is hosted by Robinson Meyer, the founding executive editor of Heatmap, and Jesse Jenkins, a professor of energy systems engineering at Princeton University. Jesse is off this week.

Here is an excerpt from our conversation:

Dan Stein: You can think of this set of solutions that’s very easily measurable, and to a first order approximation call that the carbon offset market. And so if you’re very obsessed about measurements and accountability, you’re playing in the offset market — which is okay, but I just think people can do better, right? Like, we need to change systems. We need to change laws. And you can’t do that with a carbon offset. So we sometimes advise companies, as well, and that’s what I tell them. I’m like, if you put yourself in this box of having to measure the amount of tons that you are reducing to solve your net zero goal, well then you’re extremely restrained in terms of the upside impact you can have.

Robinson Meyer: It seems like you’ve followed an arc that is not unrecognizable from other parts of life. Like, I think of what’s happened with effective altruism, which is kind of where GiveWell initially came out of — this idea that everyone could be saving more lives if they were way more thoughtful and exact and precise, and scrutinized their methods much better in picking which groups to give to. And that obviously has had some big successes, among them GiveWell, which is quite impressive, I think, in some ways, and has saved a lot of lives and changed how people think about development. But ultimately you do run into politics, at the end of it.

I even think in economics more broadly, there’s incredible attention given to small policy changes that can produce more or less growth and more or less equality or inequality. But then when you talk about these big picture questions like why do certain countries become rich, or why does development happen in some places and not others? Once you move past the basic geographic constraints, then as far as I can tell, the current economic answer is like, well, some places had histories that developed good institutions and some places didn’t. And if you have good institutions, you have economic growth.

And it feels like we’re hitting the institution question of climate tech, or of decarbonization. Like, yeah, your dollars could go a little farther on some sorts of carbon offsets than others. But if you really care about decarbonization, you’re actually back at this big set of very mushy questions at the intersection of society and technology and policy and politics.

Stein: Definitely. And I mean, not to get us too derailed — you know, I’m an economist, Rob. But anyway —

Meyer: That’s why I’ve intentionally driven this car into a ditch.

Stein: Development economics has also gone through waves of this. If you think of the 70s and 80s, like, early versions of the World Bank were all about institutions and getting the rules of the game, right? And then free markets will solve everything. And then you kind of get a reaction to that in the 90s and 2000s of more microdevelopment.

And now I actually think maybe the pendulum is swinging the other way, going more towards growth. Now you even see it for someone like GiveWell. They’re now making a ton of grants not just to these super measurable direct intervention orgs, but to more meta orgs that are trying to increase the total amount of aid or the quality of aid or health systems or whatever. It’s really hard to avoid these questions of policy and technology and markets if you’re trying to solve big problems.

Exclusive: Over 530 Local Laws Now Seek to Ban or Restrict Data Centers

The overwhelming majority of the ordinances were enacted this year, a Heatmap Pro review shows. They’re helping to drive an unprecedented surge of data center cancellations.

America’s data center backlash is gaining steam.

Anti-data-center protesters briefly interrupted President Trump’s speech at a General Motors facility in Michigan earlier this week. A day later, the country music legend Willie Nelson called on Americans to “fight against data centers invading our land.”

Washington has yet to pass major data center regulation. But the backlash is already reshaping local zoning and land use codes across the country, according to an extensive review of public records conducted by Heatmap Pro. A surge of new restrictions and bans have killed dozens of proposed data centers this year.

More than 500 counties or municipalities now actively restrict or block new data centers, according to the review. This tally includes only the most severe constraints — such as steep setback requirements, impossible noise limits, or outright bans on permit approvals — that all but forbid the construction of a data center.

The overwhelming majority of these restrictions have been enacted since the beginning of the year. Nearly 190 have been passed since June 1.

The pace of moratoriums is “accelerating,” Peter Freed, a founding partner at the Near Horizon Group and the former director of energy strategy at Meta, told me.

Broadly, these new local restrictions seem to be succeeding. More than 50 data centers have been canceled so far this year after facing local pushback of some kind, according to a Heatmap Pro review of press accounts, public records, and project cancellations.

That’s more than twice as many projects as were canceled under similar circumstances in all of 2025, according to our data. Eight projects were canceled in July alone.

Ominously for developers, the rate of projects facing cancellations seems to be increasing over time.

1. Commonwealth Fusion Systems raises another $1 billion

Last month, I toured Commonwealth Fusion Systems’ headquarters in small-town central Massachusetts. The place was abuzz in activity. On the factory floor side, workers were assembling the magnets needed to ultimately form the torus-shaped reactor — think a giant doughnut with an interior that curves like the core of an apple — called the tokamak. On the actual reactor side, SPARC — the prototype that CFS expects will make history next year as the first private enterprise and only tokamak to ever generate more energy that it took to start the fusion reaction — was starting to look like a functional machine from my view on a second-story walkway overlooking the sterile assembly room. The old joke that fusion is the energy source of tomorrow — and always will be — certainly didn’t ring as funny now. I’ll tell you who isn’t laughing: All the new investors that just poured another $1 billion into CFS. The company announced its latest funding round early this morning, which brings the startup’s total fundraising since its launch as a spinout from the Massachusetts Institute of Technology in 2018 to $4 billion. CFS now accounts for 30% of all the private capital that has flowed into fusion. What distinguishes this round, my colleague Katie Brigham wrote, is that the money is coming from a bunch of institutional investors, such as pension funds and sovereign wealth funds, rather than venture capitalists. On a call with reporters this week, CFS’s newly-named chief financial officer, Lorence Kim, said it’s the first-time institutional investors comprised the majority of the new funding. When I asked the company’s spokeswoman for a percentage estimate breaking down the new versus old investors in this round, she declined to comment. Kim cautioned that the funding isn’t the kind of capital you raise before launching on a stock market. But his hire is notable. The former Goldman Sachs banker famously helped take the pharmaceutical giant Moderna public and held the top financial role through the start of the Covid-19 pandemic.

Commonwealth Fusion Systems Wins Over New Class of Investors With $1 Billion Raise

Risk-averse but deep-pocked institutional investors join the party.

Commonwealth Fusion Systems Wins Over New Class of Investors With $1 Billion Raise

When the Fusion Industry Association surveyed the sector earlier this month, it found that the industry’s 56 active companies had collectively raised more than $14.2 billion over the past five years. But an ever-larger share of that money is ending up in the hands of one startup: Commonwealth Fusion Systems.

With its latest $1 billion funding round, announced today, the MIT spinout now accounts for nearly 30% of all capital in the industry. The new financing, led by a wave of institutional investors entering the sector for the first time, will support construction of the company’s first commercial power plant in Chesterfield County, Virginia, which CEO Bob Mumgaard says is on track to come online in the early 2030s.
