Bill Gates’ climate tech advocacy organization has told its partners that it will slash its grantmaking budget this year, dealing a blow to climate-focused policy and advocacy groups that relied on the Microsoft founder, Heatmap has learned.
Breakthrough Energy, the umbrella organization for Gates’ various climate-focused programs, alerted many nonprofit grantees earlier this month that it would not be renewing its support for them. This pullback will not affect Breakthrough’s $3.5 billion climate-focused venture capital arm, Breakthrough Energy Ventures, which funds an extensive portfolio of climate tech companies. Breakthrough’s fellowship program, which provides early-stage climate tech leaders with funding and assistance, will also remain intact, a spokesperson confirmed. They would not comment on whether this change will lead to layoffs at Breakthrough Energy.
“Bill Gates and Breakthrough Energy remain as committed as ever to using our voice and resources to advocate for the energy innovations needed to address climate change,” the Breakthrough spokesperson told me in a written statement. “We continue to believe that innovation in energy is essential for achieving global climate goals and securing a prosperous, sustainable world for future generations.”
Gates founded Breakthrough Energy in 2015 to help develop and deploy technologies that would help the world reach net-zero emissions by 2050. The organization made more than $96 million in grants in 2023, the most recent year for which data is available.

Among its beneficiaries was the Breakthrough Institute, a California-based think tank that promotes technological solutions to climate change. (Despite having a similar name, it is not affiliated with Breakthrough Energy.) Last week, a representative from Breakthrough Energy told the institute’s executive director, Ted Nordhaus, that its funding would not be renewed. The Breakthrough Institute had previously received a two-year grant of about $1.2 million per year, which wrapped up this month.
“What we were told is that they are ceasing all of their climate grantmaking — zeroed out immediately after the USAID shutdown because Bill wants to refocus all of his grantmaking efforts on global health,” Nordhaus told me on Monday, referring to the Trump administration’s efforts to defund the United States Agency for International Development. “But it’s very clear that this wasn’t brought on solely by USAID. I had heard from several people that there was a big reassessment going on for a couple of months.”
The Breakthrough spokesperson disputed this characterization, and denied that cutbacks were due to the USAID shutdown or a shift in funding from climate to global health initiatives. The spokesperson also told me that some grantmaking budget remains, though they would not reveal how much.
As for Breakthrough Institute, the funding cut will primarily impact its agricultural program, which received about 90% of its budget from Breakthrough Energy. Nordhaus is trying to figure out how to keep that program afloat, while the institute’s other three areas of policy focus — energy and climate, nuclear innovation, and energy and development — remain largely unaffected.
Multiple other organizations confirmed to Heatmap that they also will not receive future grants from Breakthrough Energy. A representative for the American Center for Life Cycle Assessment, a trade organization for sustainability professionals, told me that Breakthrough had recently informed the group that it would not renew a $400,000 grant, which is set to wrap up this May. (ACLCA’s spokesperson also noted that the grant had not come with any indication that it would be renewed.) Another former grantee told me that while their organization is currently wrapping up a grant with Breakthrough and does not have anything in the works with them for this year, they expected that future funding would be impacted, though they did not explain why.
Breakthrough Energy made up a relatively small share — perhaps 1% — of climate philanthropy worldwide. Foundations and individuals around the world gave a total of $9 billion to $15 billion to climate causes in 2023, according to an analysis from the Climateworks Foundation.
But what has made Breakthrough Energy distinctive is its support for policy and advocacy groups that promote a wide range of technological solutions, including nuclear energy and direct air capture, to fight climate change.
“Their presence will be missed,” said the CEO of another climate nonprofit who was notified by Breakthrough that its funding would not be renewed. Breakthrough Energy “was one of the few funders supporting pragmatic research and advocacy work that pushed at neglected areas such as the need for zero-carbon firm power and accelerated energy innovation,” they added.
"Even if it’s a drop in the bucket, it still makes a difference,” another former grantee with a particularly large budget told me. This organization recently sent Breakthrough an inquiry about partnering up again and is waiting to hear back. “But for small organizations, it’s make it or break it.”
Speculation abounds as to the rationale behind Breakthrough’s funding cuts. “I have heard that one of the reasons that Bill decided to stop funding climate was that he concluded that there was so much money in climate that his money really wasn’t that important,” Nordhaus told me. But that is not true when it comes to agriculture, he said, which comprises about 12% of global emissions. ”There’s very little money for advocating for agriculture innovation to address the climate impacts of the ag sector,” Nordhaus told me.
Gates, who privately donated to a nonprofit affiliated with the Harris campaign in 2024 but did not endorse the Democrat, dined with Trump and Susie Wiles, the White House chief of staff, for more than three hours at Mar-a-Lago around New Year’s Day, he told Wall Street Journal editor-in-chief Emma Tucker. He said that Trump was interested in the possibility of eradicating polio or developing an HIV vaccine. “I felt like he was energized and looking forward to helping to drive innovation,” he told her, days before the inauguration.
Since then, Trump’s war on USAID has frozen funding to a polio eradication program and shut down the phase 1 clinical trial of an HIV vaccine in South Africa, Kenya, and Uganda.
