United Nations sees higher global warming even if countries reduce emissions

By the Editorial Team · Thursday, October 22, 2026

The United Nations Environment Programme reports that global temperatures are projected to rise by about 1.2 degrees Celsius above current levels even if countries meet their current emission reduction pledges, with the United States driving much of the recent increase due to higher emissions and coal use. This revised outlook highlights the difficulty of meeting Paris Agreement targets and signals that global warming could reach 2.6 degrees Celsius by 2100 under current policies.

A recent update from the United Nations Environment Programme (UNEP) indicates that the world is on track to experience greater global warming than previously anticipated, even if countries fulfill their current emission reduction commitments. Released on Wednesday, the report highlights that if all promised actions are implemented, global temperatures are projected to rise by approximately 1.2 degrees Celsius above present levels, an increase of 0.1 degrees Celsius compared to projections made last year.

The report identifies the United States as a significant factor behind the upward revision. It attributes this in part to the formal withdrawal of the U.S. from the 2015 Paris Agreement and revised assessments of historical emissions, which have contributed to higher global temperature forecasts. According to the findings, the U.S. experienced a marked increase in emissions in 2025, adding 133 million tons of carbon dioxide equivalent—a rise that surpasses emission changes seen in all other top 20 major economies. This growth was driven largely by increased electricity demand and a resurgence in coal-fired power generation.

In contrast, most other leading economies either reduced their carbon output or managed to slow the growth of their emissions. Among 187 countries analyzed, 124 reported emission increases in 2025, while 63—predominantly European nations—achieved reductions. The U.S. alone accounted for roughly 70 percent of the global rise in emissions during that period, which totaled 189 million tonnes.

Climate analysts have expressed concern over the U.S. policies. Bill Hare, chief executive of Climate Analytics, criticized the country's approach, saying it actively hinders renewable energy development while promoting coal subsidies. Hare described U.S. environmental diplomacy as undermining global climate action efforts by encouraging other nations to delay or retract their commitments.

The UNEP report also assessed future temperature trajectories based on current policy scenarios. If countries meet all their pledged targets, global temperatures are expected to rise by about 2.6 degrees Celsius above preindustrial levels by 2100. Without these commitments being realized, the world would face an estimated increase of 2.8 degrees Celsius by the end of the century, consistent with last year’s projections.

Both scenarios significantly exceed the goals set by the Paris Agreement of capping global warming to well below 2 degrees Celsius and pursuing efforts to limit the rise to 1.5 degrees. The findings underscore the growing challenges in global climate efforts amid shifting national policies and increased emissions from key economies.
