America’s Irreversible Goodbye to Climate Governance

In January, President Donald Trump signed an executive order to withdraw the United States from 66 international organizations deemed “redundant, poorly managed, unnecessary, costly, ineffective,” or that were instruments of America’s adversaries. Among them are various United Nations agencies and, most significantly, the Intergovernmental Panel on Climate Change (IPCC) and the 1992 United Nations Framework Convention on Climate Change (UNFCCC), the latter of which is the backbone of global climate governance.

 

During his first term, President Trump removed the U.S. from the Paris Agreement. But a newly elected President Joe Biden promptly returned the nation to the agreement in 2021, making it a central gesture of his climate diplomacy. The episode exposed the fragility of America’s international climate policy: A simple change in administration could send the U.S. in or out of sweeping, long-term agreements, rendering global climate commitments mere extensions of domestic, partisan politics.

 

This time, however, there is a degree of permanence to the change. By targeting the UNFCCC itself, the Trump administration has dismantled the legal framework that made possible reversal by a simple executive decree.

 

Adopted under the 1992 Convention, the Paris Agreement is built on the institutional architecture of the UNFCCC, whose bodies provide the agreement with necessary support. These include the Conference of the Parties, the secretariat, and a system for financial contributions. Paragraph 3 of Article 28 of the Paris Agreement reads as follows: “Any Party that withdraws from the Convention shall be considered as also having withdrawn from this Agreement.” By leaving the Framework Convention, Washington severs the link that allowed Biden’s reentry into the Paris Agreement. Trump’s withdrawal is not tactical, but structural.

 

The key precedent insulating Trump’s decision from a Supreme Court challenge is Goldwater v. Carter, in which the high court in 1979 declined to review President Carter’s unilateral termination of a mutual defense treaty with Taiwan, strengthening executive authority over treaty withdrawals. In practice, therefore, a president can withdraw from a treaty without a clear judicial avenue to stop him. The Trump administration sits in a legally comfortable position: Opponents have no leverage to undo the move, and attempts to seek a new Supreme Court ruling would risk further entrenching executive power over treaty termination.

 

Democrats are paying the price for designing Paris to avoid Senate ratification. Knowing they lacked a two-thirds majority in the upper chamber, the Obama administration insisted on voluntary, non-binding contributions and targets, which ensured Paris would rest on a reversible presidential signature rather than durable treaty law.

 

The Trump administration has fully absorbed these lessons. During his first term, Trump withdrew only from the Paris Agreement, leaving the UNFCCC intact and allowing his successor to rejoin easily. This time, Trump’s action is far more radical: By targeting the Framework Convention itself, Trump deprives future presidents of an easy diplomatic reversal.

 

Politically, the message is clear: Washington increasingly views climate diplomacy as an instrument of external constraint — beneficial to America’s strategic competitors, a burden on U.S. industrial competitiveness, and costly.

 

Formally, the U.S. could rejoin the UNFCCC, but it would now require a level of political consensus that no longer exists. Approved in 1992, when bipartisan faith in a painless energy transition was at an all-time high, the Convention today confronts economic and geopolitical realities that expose prior illusions and make revival unlikely any time soon.

 

What are Europe’s climate true believers supposed to do now? One question, though rarely voiced publicly in Brussels, Strasbourg, or Berlin, persists in the minds of European Union policymakers and regulators: How long will the EU remain wedded to a climate strategy that no longer meaningfully binds either the United States or emerging nations beyond toothless declarations? The EU continues to lock itself into ever more ambitious targets (a 90 percent carbon dioxide reduction from 1990 levels by 2040), while eroding its industrial base, deepening its dependence on China, and widening the gap between rhetoric and the reality of global emissions.

 

Instead of responding to Trump’s withdrawal with their usual ritual denunciations, European leaders should ask the following question: If the world’s leading economic and military power no longer wants to be trapped in U.N.‑led climate architecture, isn’t it time for the EU to reassess its own commitments with clear eyes? The wrong answer will leave Europe discovering too late that it has sacrificed its prosperity and strategic autonomy to a climate lunacy abandoned by its closest — and most consequential — allies.
