Last year, according to Banking on Climate Chaos—released by groups including the Rainforest Action Network, Sierra Club, and Oil Change International—the world's largest financial institutions committed $906 billion in financing to fossil fuel companies, representing an 8% increase over funding the previous year.
The groups emphasized that the banks financed pollution-causing oil, gas, and coal projects even as they made "voluntary commitments" to “aligning their lending, investment, and capital markets activities with net-zero greenhouse gas emissions by 2050," as a now-defunct United Nations-backed scheme called the Net-Zero Banking Alliance (NZBA) pledged.
More than a decade after countries agreed to the Paris climate accord and pledged to take action in a push to avert planetary heating over 1.5°C above pre-industrial temperatures, the report notes, "banks maintain and are expected to uphold climate policies independent of the NZBA."
However, it continues, "the collapse of the NZBA—culminating in its cessation of operations in October 2025—freed banks to further unwind from climate targets and other elements of their climate strategies."
"Notably, throughout 2025 and the first half of 2026, banks have further weakened their commitments to uphold 1.5˚C temperature rise limits, widened loopholes, and undercut sector policies for coal, oil, and gas energy or power supply primarily by removing or diluting exclusion criteria and commitments. Most policy changes in the past year were downgrades of existing policies rather than improvements," reads the report.
"Voluntary commitments aren’t working. No major oil and gas company is doing anything even close to what is needed to hold global heating to 1.5°C, and voluntary banking sector pledges like the Net Zero Banking Alliance aren’t cutting their pipeline of cash."
Diogo Silva, campaign lead for BankTrack and a co-author of the report, said: "Banks keep telling us they’re committed to climate. Then they abandon their own policies the moment political pressure mounts. Voluntary pledges have had their chance. We need binding rules—not promises.”
Banking on Climate Chaos highlights the banks that spent the most money investing in fossil fuel projects, with JPMorgan Chase named the leading financier of oil, coal, and gas. The Wall Street firm spent $58 billion in 2025, the same year it also "weakened" its own climate policy.
"Of the 15 North American banks in scope, 12 now have no meaningful fossil fuel commitments," said Rainforest Action network. "JPMorgan Chase and Goldman Sachs abandoned their coal and Arctic exclusions entirely, converting them into case-by-case due diligence standards."
JPMorgan Chase is one of three US banks listed in the top five fossil fuel backers; Bank of America financed the second-largest amount of pollution-causing projects at $47 billion, while Citigroup poured more than $45 billion into fossil fuels. Two Japanese institutions, Mitsubishi UFJ Financial Group and Mizuho Financial, were also in the top five.
With President Donald Trump taking executive action last year aimed at pressuring companies to back fossil fuel interests and "disregard social or environmental considerations," the report notes, US banks' share of all global fossil fuel financing increased to 32%, representing "the single largest source of fossil capital in the world." In 2021, US banks provided 28% of fossil fuel investment.
Trump has also aggressively pushed for more coal production since taking office for his second term in January 2025, and financing for coal mining expansion surged 77% in 2025, to $84 billion. Funding for coal power also grew by 40%, with companies pouring $81 billion into coal-fired plants.
Even when asked about the report's findings, top banks pointed to their own voluntary commitments to finance renewable energy projects and "achieve net zero financed emissions by 2050," as a spokesperson for Citigroup said to The Guardian.
The spokesperson said the bank "supports clients in the low‑carbon transition while recognizing the real need for secure, affordable and reliable energy today. We are committed to... advancing our $1 trillion sustainable finance goal, with a focus on balancing the transition with global energy resilience”.
David Tong, global industry campaign manager for Oil Change International and a co-author of the report, warned that "every dollar of finance for oil and gas helps an industry of war profiteers squeeze out short-term profits, further trapping communities into paying higher fossil fuel energy bills, fueling war and conflict, and burning all our futures."
"Voluntary commitments aren’t working. No major oil and gas company is doing anything even close to what is needed to hold global heating to 1.5°C, and voluntary banking sector pledges like the Net Zero Banking Alliance aren’t cutting their pipeline of cash," he said. "Instead, banks have injected over staggering $900 billion into fossil fuel financing in 2025 alone. Governments must step in and take urgent action to hold financial institutions and fossil fuel companies accountable for their role in the climate crisis.”
Since the Paris climate agreement, the report says, banks have poured a staggering $8.7 trillion into the fossil fuel industry, with the "Dirty Dozen," as the authors call the 12 largest fossil fuel financial backers, providing nearly 40% of all investment for coal, oil, and gas extraction.
The report makes demands of banks, calling on them to "exclude all finance for fossil fuel expansion immediately" and "require robust, 1.5°C-aligned transition plans from all existing fossil fuel clients"—but emphasizes that governments must compel financial institutions to end financing for oil, gas, and coal.
"After two consecutive years of fossil fuel finance increases by global banks—especially the increase in fossil fuel expansion finance and the continued backtracking from banks on their climate pledges—it is clear that the banking sector will not voluntarily take the necessary steps to transition out of fossil fuel finance at the pace and scale needed for the world to deliver on the Paris Agreement goals," reads the report.
Instead, it says, governments must mandate transition planning by banks, private equity holders, insurers, and other companies; make polluters pay for climate damages; ensure public finance institutions are subject to transparent reporting and legal accountability to international standards, and rapidly wind down supply-side fossil fuel subsidies, tax exemptions, subsidies, guarantees or other public assistance for new oil, gas, and coal projects.
"A decade after Paris, just twelve banks now drive more than a third of the world’s fossil fuel financing—proof that this is no longer a problem of markets, but of a small set of decision-makers making active choices," said Niko Lusiani, research director for Rainforest Action Network. "They are choosing to lock in an energy system that hands record profits to a few fossil firms while passing the costs onto the three of every four people on Earth who depend on imported fuel."
"The good news is that what a handful of banks built," said Lusiani, "governments and people worldwide have the power to change.”
