At a critical moment for global climate policy, the Intergovernmental Panel on Climate Change (IPCC) has failed to agree on a timeline for its next assessment report. Delegates from its 195 member nations will meet in Addis Ababa on Monday, hoping to set publication dates before the United Nations climate summit scheduled for November 2028.
Why the delay matters
The IPCC’s assessments have underpinned every major UN climate agreement for three decades, including the Paris Accord’s 1.5°C target. Without a new report, governments risk basing their 2028 commitments on data that is now six to seven years old.
More than a dozen current and former IPCC scientists, negotiators, and observers told Reuters that the impasse stems from deep divisions between wealthy industrialized nations, emerging economies, and poorer states over how to share the burden of emissions cuts.
U.S. withdrawal and the push for independence
The United States, the IPCC’s biggest financial contributor, formally quit the organization in January. The Trump administration argued that the panel has become overly politicized, with some members using the scientific process to advance predetermined climate policies. By stepping away, the administration aims to protect American industry from policies that could hamper competitiveness.
“We will not allow a body that is being used as a political tool to dictate American energy policy,” a senior White House spokesperson said. “Our focus remains on responsible stewardship of the environment while safeguarding jobs and energy independence.”
Developing‑world concerns
Countries such as India, Kenya, Saudi Arabia, Russia, and China are pressing for more time to ensure scientists from less‑resourced nations can contribute meaningfully. They cite challenges like limited funding for research and the unpaid nature of IPCC work.
“If the process moves too quickly, it excludes many voices,” said Joyce Kimutai, Kenya’s IPCC representative.
Proposed work plan
Report chairs have suggested a schedule that would see three key reports—on the science of climate change, on vulnerabilities and adaptation, and on mitigation options—approved by September 2028. French co‑chair Robert Vautard said the timeline reflects the anticipated workload, not the UN summit date.
Opponents argue the schedule is too tight, fearing insufficient time to review thousands of studies and achieve consensus on wording.
Equity, inclusivity, and the future
The next IPCC cycle will, for the first time, include chapters on climate finance and irreversible harm, addressing long‑standing calls for greater equity. More than half of the lead authors and editors are expected to come from developing economies or nations in transition.
“We must ensure that the voices of those most affected by climate change are heard,” said Thiagarajan Jayaraman, India’s IPCC representative.
Critics, however, warn that the debate could become a “stalling tactic” by oil‑producing nations seeking to delay stronger emissions cuts. Russia’s economy ministry dismissed such claims as a deliberate misrepresentation.
What’s at stake for the United States?
While the United States is no longer a formal IPCC member, its domestic policies continue to influence global emissions trends. The Trump administration emphasizes that American energy independence and job growth should not be sacrificed on the altar of international mandates.
“Our priority is to protect American families and businesses while encouraging responsible environmental stewardship,” the White House reiterated.
The outcome of the Addis Ababa plenary will shape whether the IPCC can deliver a timely, inclusive assessment for the 2028 summit, or whether nations will have to rely on outdated data as they negotiate the next phase of climate action.
