UN Warns Climate Goals Are Slipping, With U.S. Partly to Blame

WHO:

The Guardian - Inger Andersen said the effort to stay within the 1.5°C limit had not been made: “We procrastinated, and now we are saying this window has closed.”

The Guardian - Mohamed Adow said solar and wind power were growing faster than expected, while governments were not moving away from fossil fuels quickly enough.

NPR - The United States was tied with Russia for the highest greenhouse-gas emissions per capita among the world’s largest emitters; China produced more total emissions than the U.S. while having more than four times its population.

NPR - The U.S. government said it “does not endorse or agree with [the report’s] analysis or conclusions” and had not provided comments.

The Guardian - The United States was described as the world’s second-biggest greenhouse-gas emitter, after China.

The Guardian - Bill Hare said the United States and Saudi Arabia together produce 20–25% of the world’s fossil fuels.

Fast Company - The United Nations Environment Programme (UNEP) issued updated climate calculations; Anne Olhoff, director of the UNEP Copenhagen Climate Centre, was the report’s lead author.

Fast Company - United Nations Secretary-General António Guterres said the world was falling “dangerously short” of climate goals but had tools to change course.

Fast Company - UNEP Executive Director Inger Andersen said global emissions cuts were necessary to return to a more manageable climate.

Fast Company - Australian climate scientist Bill Hare, CEO of Climate Analytics, criticized U.S. policies; he was not part of the UN report.

Fast Company - Climate scientist Adelle Thomas, vice chair of a UN scientific assessment on climate impacts, said the tools to act were available; she was not part of the study.

Fast Company - Mohamed Adow, director of Power Shift Africa; Michael Mann of the University of Pennsylvania; Johan Rockstrom, director of the Potsdam Institute for Climate Impacts Research; and Australian climate scientist Malte Meinshausen commented on the consequences or wider effects of U.S. policy.

Phys.org - A UN report said the United States was a major contributor to worsening climate projections.

ABC News Business - Reported that humanity was losing ground in the fight against climate change.

WHAT:

The Guardian - UNEP said cutting greenhouse gases by 45% by 2035 would give a good chance of limiting warming to 1.7°C above preindustrial levels.

The Guardian - The report said the 1.5°C warming limit has been exceeded, but limiting the overshoot remains possible.

NPR - The European Union had invested heavily in energy-efficient appliances and renewable electricity, including wind and solar.

NPR - The United Nations report said that keeping global warming below 3.6°F (2°C) would still be possible if greenhouse-gas emissions fell by about 25% over the next decade; submitted national plans would cut emissions by only about 15%.

NPR - The report described the Earth as about 2.7°F (1.5°C) warmer than in the mid-1800s and warned that warming of 5°F (2.8°C) this century could cause massive sea-level rise and mass extinction of plants and animals.

NPR - The Trump administration ordered U.S. coal-fired power plants to stay open longer than planned, rolled back vehicle fuel-efficiency standards, and ended tax credits for solar and wind projects.

NPR - The administration is working to remove the U.S. from all U.N. climate work; the Environmental Protection Agency reversed its previous position and now says greenhouse gases do not threaten human health and welfare.

NPR - The annual report said about two-thirds of countries had submitted updated formal emissions-cutting plans. If fulfilled, those plans would reduce emissions by about 15% over the next decade, compared with a 25% reduction needed to keep warming below 3.6°F (2°C).

The Guardian - UNEP said global emissions in 2025 were broadly similar to the previous year, but analysts cautioned against calling this a peak or plateau.

The Guardian - UNEP estimated that cutting emissions by 18% by 2030 and 45% by 2035 would give a good chance of limiting warming to 1.7°C above preindustrial levels.

The Guardian - Rockström said that if current national commitments are implemented, annual global emissions would be approximately 50 gigatonnes of CO₂ equivalent by 2035, versus a target of below 35 gigatonnes.

The Guardian - UNEP identified methane cuts as a way to limit warming quickly and said methane is 80 times more powerful than carbon dioxide.

Fast Company - If countries fulfill their climate plans, global temperatures are projected to rise 2.6°C (4.7°F) above pre-industrial levels by 2100; under the current path without national promises, warming is projected at 2.8°C (5°F).

Fast Company - The report projected 2.2°F (1.2°C) of additional warming above current temperatures if countries meet their promises—about 0.2°F (0.1°C) more than the previous year’s projection.

Fast Company - The U.S. increased emissions by 133 megatons of CO₂ equivalent, attributed to higher electricity demand and a rebound in coal-fired power.

Fast Company - Of 124 countries that increased emissions, excluding 63 that reduced them, the increase totaled 189 million tons of CO₂ in 2025; the report attributed 70% of that increase to the U.S.

Fast Company - The report said all other top 20 major economies reduced carbon pollution or slowed its growth.

Fast Company - The report said U.S. withdrawal from the Paris Agreement and revised historical-emissions estimates worsened the projection. Olhoff said the U.S. policy change could add 0.1°C (nearly 0.2°F) to global temperatures by the end of the century.

Fast Company - The Paris climate pact’s goals are to limit warming to below 2°C (3.6°F), preferably 1.5°C (2.7°F). The world is at about 1.4°C (2.5°F) above pre-industrial levels; UN officials said the 1.5°C goal could no longer be achieved.

Fast Company - Andersen said emissions must fall 18% by 2030 and 69% by 2040. Hare said an extra 0.1°C could expose another 140 million people to dangerously hot conditions; Mann estimated it could cost the global economy about $1.2 trillion.

WHERE:

NPR - Global climate talks were set to take place in Turkey; the Trump administration would not participate.

Fast Company - The report discussed global warming and emissions worldwide, including impacts on vulnerable communities in Africa and possible risks to the Amazon rainforest and ice sheets in Greenland and Antarctica.

WHEN:

The Guardian - The next assessment of emissions targets under the Paris Agreement’s “global stocktake” mechanism is scheduled for 2028.

WHY:

NPR - Inger Andersen said global oil and gas disruptions stemming from wars in Ukraine and Iran had prompted countries to scramble over energy security.

NPR - The Trump administration said the international system imposed unfair burdens on Americans as its reason for withdrawing from U.N. climate work.

The Guardian - The Guardian reported that the IPCC failed to set a timetable for publishing its latest report before the 2028 global stocktake, potentially preventing governments from assessing progress against the latest science.

Fast Company - The report linked increased U.S. emissions to greater electricity demand and renewed coal-power generation; it linked the changed outlook partly to U.S. withdrawal from the Paris Agreement.

HOW:

The Guardian - The Paris Agreement’s “global stocktake” mechanism is intended to correct shortfalls in countries’ emissions commitments.

Fast Company - The report compared projected warming under countries’ submitted climate plans with warming under the current path without those promises.

Fast Company - UN officials said limiting warming to about 1.8°C and later removing enough CO₂ from the air might bring temperatures back to 1.5°C.

A new United Nations climate assessment warns that countries are falling well short of the cuts needed to limit dangerous warming, with the United States a major contributor to worsening projections. The report says current national plans would reduce emissions by about 15% over the next decade, while roughly 25% is needed to keep warming below 2 degrees Celsius. Even if countries meet their promises, temperatures could rise 2.6 degrees by 2100. UNEP chief Inger Andersen says the window to meet the 1.5-degree goal has closed, though limiting the overshoot remains possible. She says emissions need to fall 18% by 2030 and 45% by 2035 for a good chance of limiting warming to 1.7 degrees. U.S. emissions rose as electricity demand increased and coal power rebounded, while the Trump administration rolled back clean-energy policies. The next assessment under the Paris Agreement is scheduled for 2028.

A new United Nations climate report says countries’ current plans fall far short of the emissions cuts needed to limit dangerous warming, with U.S. policy worsening the outlook. If nations meet their pledges, temperatures are projected to rise 2.6°C by 2100; without them, the estimate is 2.8°C. The report says emissions must drop 25% over the next decade to keep warming below 2°C, but submitted plans would cut them by only about 15%. U.S. emissions rose as electricity demand increased and coal power rebounded, while the administration rolled back clean-energy policies and is seeking to withdraw from U.N. climate work. The United States is among the highest emitters per person, while China produces more overall. U.N. officials say tools to change course remain available, including sharp cuts to methane. The next assessment of national targets is scheduled for 2028.

(UPDATED October 22, 2026 02:13 UTC)

A new United Nations climate assessment says the world is falling further behind its warming goals, with U.S. policy changes worsening the outlook. The Trump administration has expanded coal power, rolled back vehicle efficiency standards, ended renewable-energy tax credits, and is moving to withdraw the United States from U.N. climate work. U.S. emissions rose by 133 million tons of carbon dioxide equivalent, driven by electricity demand and a rebound in coal. The report projects warming of 2.6 degrees Celsius by 2100 if countries meet their climate plans, and 2.8 degrees on the current path. Those plans would cut emissions about 15% over the next decade, short of the 25% needed to stay below 2 degrees. UNEP says steep emissions cuts, including methane reductions, could still limit damage. The U.S. government rejected the report’s analysis and conclusions.

(UPDATED October 21, 2026 18:12 UTC)

A United Nations climate report says the world is falling further behind its emissions goals, with rising U.S. pollution worsening the outlook. The United States, the world’s second-largest greenhouse gas emitter after China, accounted for 70% of emissions growth among countries that increased pollution in 2025. Higher electricity demand and a rebound in coal power drove the U.S. increase, while other major economies cut emissions or slowed their growth. If countries meet their climate plans, warming is projected to reach 2.6 degrees Celsius by 2100; without those promises, the estimate is 2.8 degrees. The UN says emissions need to fall 18% by 2030, and methane cuts could curb warming quickly. Officials say the 1.5-degree target is no longer achievable, though limiting warming to about 1.8 degrees and later removing carbon dioxide could bring temperatures back down. The next global stocktake is scheduled for 2028.
