Not yet, based on the available evidence. The Gates Foundation’s 2045 strategy puts maternal and child health, infectious disease, and poverty reduction at its center, while its climate work continues where it overlaps with agriculture and health. The concern that climate could receive less attention is a forecast about future emphasis—not evidence that the foundation has cut its climate funding overall.
What changed in Gates’ philanthropic plans?
In 2025, Bill Gates said he would give 99% of his wealth to the Gates Foundation over the coming two decades, with the foundation scheduled to close in 2045. In February 2026, the foundation said it was committed to spending $200 billion over 20 years before closing. CEO Mark Suzman described three central goals: preventing maternal and child deaths, fighting deadly infectious diseases, and helping hundreds of millions of people escape poverty. The foundation says accelerated spending will emphasize proven interventions such as immunization, nutrition, and maternal health, as well as new tools against malaria, tuberculosis, and other infectious diseases. The foundation’s 2026 announcement sets out that strategy.
The shift prompted a concern from climate investors: if Gates makes the foundation his main philanthropic vehicle, a major near-term increase in climate funding may be less likely. GeekWire reported that concern in May 2025, alongside earlier cuts to policy and partnership teams at Gates’ climate organization, Breakthrough Energy. A spokesperson said Gates remained committed to clean-energy innovation. The investor concern is an attributed prediction, not proof that the foundation subsequently reduced its climate budget. GeekWire’s report provides the original framing.
Is the Gates Foundation still funding climate work?
Yes. Its current climate-related commitments include farmer adaptation and climate-resilient health systems. They show ongoing activity, but they are not a complete accounting of the foundation’s climate spending.
#1 Best Overall
Climate adaptation for smallholder farmers
At COP30, the foundation announced $1.4 billion over 2026–2029 for innovations to help smallholder farmers adapt to climate change. The work is aimed at sub-Saharan Africa and South Asia, where farmers face rising temperatures, drought, erratic rainfall, floods, storms, and crop and livestock pests and diseases. The foundation lists farmer-facing digital tools, including AI-supported local weather forecasts, among possible approaches. It says the work will be designed with focus countries and in partnership with other funders. The announcement and its COP30 fact sheet describe the commitment and intended focus.
The fact sheet says that “less than one percent of climate finance has been designed to address the growing array of climate threats to food systems supplied by smallholder farmers in sub-Saharan Africa and South Asia.” That is the foundation’s characterization in its fact sheet, not an independently verified estimate of global climate finance.
Climate resilience in health systems
In January 2025, the Global Fund, the Gates Foundation, and Sanofi’s philanthropic organization Foundation S announced a $50 million Climate and Health Catalytic Fund. The announced amount comprises a $40 million Gates Foundation match agreement and $10 million from Foundation S. The fund is intended to help vulnerable countries respond to climate-related health effects and build low-carbon, climate-resilient health systems. The Global Fund’s announcement describes the fund.
Why the foundation treats climate as an intersection, not a central priority
Suzman has said the foundation does not intend to make environmental issues a major standalone focus. In a foundation interview, he said it would not shift its priorities toward “heavily working on environmental issues,” while describing climate-related work through agriculture and smallholder farmers—for example, drought- or flood-resistant crops and livestock, and better water and soil management. That interview explains the foundation’s strategic framing; it does not establish the exact shape of every part of its 2026 portfolio. The interview with Suzman discusses the distinction.

In GeekWire’s May 2025 report, Suzman said: “In those areas like climate, our focus has always been in the areas of intersection where we think philanthropic capital can make the greatest difference.” The practical question is therefore whether this narrower, integrated approach leaves enough room and funding for climate work—not whether the foundation has stopped all climate activity.
What the numbers do—and do not—show
The announced commitments should be read in context. The farmer-adaptation pledge is specific to 2026–2029, and the Climate and Health Catalytic Fund is a separate $50 million initiative. Neither figure is the foundation’s total climate budget. The foundation reported $8.47 billion in charitable support in 2025, but that is total support across its work, not climate-specific spending. The foundation’s 2025 grantmaking announcement gives that overall figure.
The available sources do not provide a complete climate-specific spending series, so they cannot establish whether Gates Foundation climate funding has risen or fallen overall, quantify a future cut, or support a like-for-like comparison between climate and global-health spending. They also do not make announced commitments equivalent to money already disbursed.

In October 2025, Gates argued that climate policy should put human welfare, poverty, and disease prevention at the center while still treating climate change as serious. The Associated Press reported his position and scientists’ concerns about balancing near-term welfare against long-term climate action. Gates wrote: “If you think climate is not important, you won’t agree with the memo. If you think climate is the only cause and apocalyptic, you won’t agree with the memo.” That is his public argument about climate priorities; it is not evidence of a change in the foundation’s budget. The Associated Press report covers the memo and the responses to it.
Best Value
For readers weighing the competing claims, four distinctions matter: adaptation versus emissions mitigation; climate programs in their own right versus climate work integrated with agriculture or health; announced commitments versus total spending actually disbursed; and Gates’ personal public arguments versus the foundation’s institutional strategy. Confusing any of these can make a limited commitment look like a full climate budget—or a policy argument look like a funding decision.
