“I’m not saying we should ignore temperature-related deaths because diseases are a bigger problem,” he writes. “What I am saying is that we should deal with disease and extreme weather in proportion to the suffering they cause, and that we should go after the underlying conditions that leave people vulnerable to them. While we need to limit the number of extremely hot and cold days, we also need to make sure that fewer people live in poverty and poor health so that extreme weather isn’t such a threat to them.”
This new focus didn’t come with a change in funding priorities — but that’s partly because some big shake-ups have already happened. In February, Heatmap reported that Breakthrough Energy, Gates’ climate-focused funding group, had slashed its grant-making budget. Gates later closed Breakthrough’s policy and advocacy office altogether.
Despite eliminating those financial commitments, he still dwells on two of his longtime obsessions in the new memo: cutting the “green premium” for energy technologies, meaning the delta between the cost of carbon-emitting and clean energy technologies, and improving the measurement of how spending can do the most for human welfare. The same topics dominated his thinking when I last spoke to the billionaire at the 2023 United Nations climate conference in Dubai.
What seems to have shifted, instead, is the global political environment. The Trump administration and Elon Musk gutted the federal government’s spending on global public health causes, such as vaccines and malaria prevention. European countries have also cut back their global aid spending, although not as dramatically as the U.S.
Gates seemingly now feels called to their defense: “Vaccines are the undisputed champion of lives saved per dollar spent,” he writes, praising the vaccine alliance Gavi in particular. “Energy innovation is a good buy not because it saves lives now, but because it will provide cheap clean energy and eventually lower emissions, which will have large benefits for human welfare in the future.”
Last week, Gates shared his thinking about climate change at a roundtable with a handful of reporters. He was, as always, engaging. I’ve shared some of his new takes on climate policy below. His quotes have been edited for clarity.
On the global setback in climate policy:
The environment we’re in today, the policies for climate change are less accommodating. It’s hard to name a country where you’d say, Oh, the climate policies are more accommodating today than they have been in the past.
Why innovation is the key to solving climate change:
The thesis I had was that middle income countries — who were already, at that time, the majority of all emissions — would never pay a premium for greenness. And so you could say, well, maybe the rich countries should subsidize that. But you know, the amounts involved would get you up to, like, 4% of rich country budgets would have to be transferred to do that. And we’re at 1% and going down. And there are some other worthy things that that money goes for, other than subsidizing positive green premium type approaches. So the thesis in the book [How to Avoid a Climate Disaster, published in 2021] is we had to innovate our way to negative green premiums for the middle income countries.
Where he differs with climate activists:
Climate [change] is an evil thing in that it’s caused by rich countries and high middle-income countries and the primary burden [falls on poor countries]. When I looked into climate activists, I said, Well, this is incredible. They care about poor countries so much. That’s wonderful, that they feel guilty about it. But in fact, a lot of climate activists, they have such an extreme view of what’s going to happen in rich countries — their climate activism is not because they care about poor farmers and Africa, it’s because they have some purported view that, like, New York City, can’t deal with the flooding or the heat.
Why national emissions reporting goals are never surprising:
The other challenge we have in the climate movement is in order to have some degree of accountability, it was very focused on short-term goals and per-country reports. And the per-country reporting thing is, in a way, a good thing, because a country — certainly when it comes to deforestation or what it’s doing on its electric grid, there is sovereign accountability for what’s being done. But I mean, the way everybody makes steel is the same. The way everybody makes the cement, it’s the same. The way we make fertilizer, it’s all the same. And so there can’t be some wonderful surprise, where some country comes in and, you know, gives you this little number [for its Paris Agreement goals], and you go, Wow, good! You’re so tough, you’re so good, you’re so amazing. Because other than deforestation and your particular electric grid, these are all global things.
Why rich countries like the United States will probably get through the next 80 years of climate change fine:
If you’re a rich country, the costs of adaptation are just one of many, many things that are not gigantic, huge percentages of GDP — you know, rebuilding L.A. so that it’s like the Getty Museum, in terms of there’s no brush that can catch on fire, there’s no roof that can catch on fire, adds about 10% cost to the rebuild. It’s not like, Oh my god, we can’t live in LA. There’s no apocalyptic story for rich countries. [Climate adaptation] is one of many things that you should pay attention to, like, Does your health system work? Does your education system work? Does your political system work? There are a variety of things that are also quite important.
The most effective tool to help poor countries prepare for climate change:
The place where it gets really tough is in these poor countries. But you know, what is the greatest tool for climate adaptation? Getting rich — growing your economy is the biggest single thing, living in conditions where you don’t face big climate problems. So when you say to an African country, Hey, you have a natural gas deposit, and we’re going to try to block you from getting financing for using that natural gas deposit … It probably won’t work, because there’s a lot of money in the world. It’s not clear how you’d achieve that. And it’s also in terms of the warming effect of that natural gas, versus the improvement of the conditions of the people in that country — it’s not even a close thing.
The risks of working with European governments on climate policy:
People in the [climate] movement, we do have to say to ourselves, For the Europeans, how much were they willing to pay in order to support climate? — and did we overestimate in terms of forcing them to switch to electric cars, to buy electric heat pumps, to have their price of electricity be higher? Did we overestimate their willingness to pay with some of those policies? And you do have to be careful because if your climate policies are too aggressive, you will be unelected, and you’ll have a right-wing government that cares not a bit about climate. I mean, God bless the Europeans for caring about climate. You worry they care so much about it that the people you talk to, you won’t be able to meet with them again, because they won’t be in power.
