The United Nations Environment Programme has released its annual assessment of the global emissions gap, concluding that a temporary breach of the 1.5C global warming target set by the Paris Agreement is now unavoidable due to decades of inadequate climate action. The organization’s report, titled “The point of return,” characterizes the situation as “sobering” and states that exceeding this threshold is both “imminent and unavoidable.” The focus has shifted from preventing an overshoot to minimizing its magnitude and duration.
According to the report’s most optimistic scenario, global temperatures would peak at approximately 1.7-1.8C in the middle of the century before declining back to 1.5C by the end of the century. Achieving even this outcome would require substantial emissions reductions of 18% by 2030 and 45% by 2035, alongside significant expansion of carbon dioxide removal technologies. Current national climate pledges, if fully implemented, fall significantly short of these targets, projecting only 5-8% emissions reductions by 2030 and 11-15% by 2035 compared to 2025 levels.
Global greenhouse gas emissions in 2025 totaled 58.4 billion tonnes of CO2 equivalent, representing a marginal decrease from 2024 levels. However, provisional data makes it difficult to determine the overall direction of emissions trends. Emissions from fossil fuels increased slightly, while reductions in land-use and forestry emissions partially offset this growth, partly due to declining wildfire activity in Africa, South America, and southeast Asia following El Niño conditions.
Among major emitters, only the United States recorded notable emissions growth in 2025, driven by increased electricity demand and expanded coal power generation. The power and transport sectors showed the most significant progress toward decarbonization, led by solar energy expansion and electric vehicle adoption, though transport sector emissions continue to rise due to growth in aviation and shipping.
The report notes that 124 countries, representing 75% of global emissions, have submitted updated climate pledges for 2035 as of early September 2026, more than double the number available at the time of the previous year’s assessment. Despite calls for comprehensive greenhouse gas targets, only modest increases have occurred in the number of nations covering all emissions sources in their pledges.
