On January 20, 2025, President Donald Trump signed an executive order directing the U.S. Ambassador to the United Nations to submit formal written notice of withdrawal from the Paris Agreement under the UNFCCC. The order also revoked the U.S. International Climate Finance Plan and instructed agencies to cease or revoke all climate-related financial commitments. This was the second U.S. withdrawal from Paris: Trump first initiated withdrawal in 2017, Biden rejoined in 2021, and Trump reversed course again on his first day back in office. Under Article 28 of the Paris Agreement, legal withdrawal took effect one year after UN notification.
The Paris Agreement was adopted in 2015 and entered into force in 2016. Trump announced the first U.S. withdrawal in 2017, which became legally effective in November 2020. Biden rejoined in January 2021, restoring U.S. participation. The 2025 withdrawal differs from 2017 in two significant ways: Trump acted on Day 1 rather than waiting months, and the order simultaneously targeted the U.S. International Climate Finance Plan and all agency climate-finance commitments, making it a broader rollback than the first exit. Internationally, the 2025 move landed in a more mature climate-finance architecture, with a global target of $1.3 trillion per year by 2035 already established.

Trump Abandons Paris Again, This Time Taking Climate Finance With Him
Left-leaning coverage framed the decision as a dramatic abandonment of global climate leadership that went well beyond a symbolic treaty exit. The recurring concern was not just the act of leaving Paris but the simultaneous revocation of the U.S. International Climate Finance Plan and the directive to agencies to freeze or rescind climate-related funding. That made the order look less like a foreign policy adjustment and more like a comprehensive rollback of U.S. climate participation. Critics argued the move undermined allied trust at a critical moment in global climate negotiations, stripped the U.S. of its seat at the table shaping future climate rules, and sent a signal to other nations that American climate commitments cannot be relied upon across administrations. The financial dimension received particular attention: the revocation of climate finance commitments was seen as undercutting the UN climate body budget and the multilateral architecture built around U.S. participation.
Key takeaway
The order was not just a Paris exit: it simultaneously revoked U.S. climate finance commitments, making it the broadest single rollback of American climate participation in history.

Trump Restores U.S. Sovereignty Over Climate Policy on Day One
Right-leaning coverage framed the order as a long-overdue reset of U.S. climate policy, ending what supporters described as costly and uneven international obligations. The central argument was that the Paris Agreement imposed disproportionate burdens on the U.S. economy, constraining domestic energy and industrial policy while allowing other major emitters to continue on their own schedules. Supporters highlighted that Trump moved immediately on Day 1, pairing the Paris exit with broader actions on energy, foreign aid, and international commitments, signaling a systematic rollback rather than a one-off diplomatic adjustment. Pro-withdrawal commentary stressed that U.S. taxpayers should not subsidize climate projects abroad while bearing disproportionate domestic compliance costs. Some right-leaning analysis noted that a second withdrawal demonstrated the Paris framework fragility when it depends on executive-branch continuity in the U.S.
Key takeaway
Trump restored U.S. control over climate and energy policy on Day 1, ending what supporters called costly international obligations that constrained American industry without equivalent burden on other major emitters.

Day-One Executive Order Initiates Second U.S. Withdrawal from Paris Climate Agreement
On January 20, 2025, President Trump signed an executive order titled Putting America First In International Environmental Agreements, directing the U.S. Ambassador to the UN to submit formal written notice of withdrawal from the Paris Agreement. Under Article 28, withdrawal takes legal effect one year after the depositary receives notice, meaning the withdrawal became effective January 27, 2026 after the U.S. notified the UN on January 27, 2025. The order simultaneously rescinded the U.S. International Climate Finance Plan and directed all federal agencies to cease or revoke climate-related financial commitments. The order did not withdraw the U.S. from the UNFCCC itself, leaving residual U.S. participation in the wider UN climate treaty architecture. The Federal Register published the order on January 29, 2025.
Key takeaway
Trump signed the order on January 20, 2025, the U.S. notified the UN on January 27, 2025, and the withdrawal became legally effective exactly one year later on January 27, 2026.
The Analysis
The order was significantly broader than its Paris exit framing suggested. While coverage focused on the treaty withdrawal, the executive order simultaneously revoked the U.S. International Climate Finance Plan and directed the Office of Management and Budget to issue guidance within 10 days for rescinding frozen climate funds, with agencies required to report on rescinded climate-finance efforts within 30 days. This made the order as much a budget and governance action as a diplomatic one, a dimension underreported in initial coverage from both sides. One specific detail from the primary source text that received little attention: the order required agencies to identify and revoke not just future commitments but purported existing commitments, suggesting a retroactive unwinding of financial obligations already in motion. The order also attached a formal Appendix A notice for the UN notification, signaling a more procedurally formalized withdrawal process than the 2017 exit. Most significantly, the order did not withdraw the U.S. from the UNFCCC itself. The U.S. retained observer-level participation in the wider climate treaty architecture even while exiting Paris, a nuance neither side fully explained to their audiences.

Why It Matters
This decision affects how the U.S. government spends money on international climate programs, how American diplomats engage in future climate negotiations, and whether the U.S. helps shape or simply inherits the rules other countries write. Over time the consequences can appear in energy prices, federal infrastructure planning, insurance costs in climate-exposed regions, and the pace of clean-energy investment. For anyone who pays utility bills, buys home insurance, or lives near a coast or wildfire zone, the downstream effects of this decision are not abstract.
