The United Nations Environment Program (UNEP) released its annual Emissions Gap report on Wednesday, October 21, 2026, stating that global average temperatures will unavoidably exceed the 1.5-degree Celsius warming target established by the Paris Climate Agreement. The report marks the first time UN authors have categorized breaching this threshold as "imminent and unavoidable," shifting the focus to limiting the duration and scale of the temperature "overshoot."
The findings are intended to inform government representatives attending the COP31 global climate talks in Turkey next month. While the Paris Agreement aimed to keep long-term temperature increases well below 2 C and preferably at 1.5 C, the new report examines scenarios where peak warming reaches 1.7 to 1.8 C before potentially returning to 1.5 C through emissions reductions and the use of carbon removal technologies.
According to the report, current national policies would lead to a warming peak of approximately 2.8 C, an estimate that rose since last year due in part to the withdrawal of the United States from the Paris Agreement. Even if existing pledges and net-zero commitments are met, peak warming is projected at 2.1 C. To achieve the lowest reported overshoot scenario of 1.7 to 1.8 C, global greenhouse gas emissions would need to fall by 18% by 2030, 45% by 2035, and 69% by 2040, relative to 2025 levels.
For households and businesses, the report outlines a concrete shift in energy and infrastructure requirements. To meet the lowest overshoot pathway, the UN indicates that renewable electricity capacity must triple by 2035, and coal power must be phased out entirely by 2040. Individual consumers may notice these changes through shifts in available energy sources and the scaling of carbon removal technologies, which the report notes have not yet been proven at a large scale. The report also highlights that the 55 most climate-vulnerable economies have already recorded over $500 billion in climate-related damages.
The report sets a framework for immediate policy deadlines, noting that every five years of carbon dioxide emissions at current levels increases peak warming by roughly 0.1 C. The findings establish the baseline for the COP31 summit in Turkey next month, where nations are expected to negotiate new emissions reduction targets. Under the Paris Agreement, governments are scheduled to submit updated national climate commitments in 2025. Failure to act urgently, the report warns, will cause the pathway to the lowest possible temperature overshoot to quickly fade as the remaining carbon budget for 1.5 C is expected to be depleted by 2030 at current emission rates.
