UN Report Calls 1.5°C Breach 'Imminent and Unavoidable' as US Emissions Rise and Washington Skips COP31

The United Nations Environment Programme has dropped the 1.5°C goal as a realistic target. Its annual Emissions Gap report, released ahead of the COP31 climate summit, says breaching the Paris Agreement limit in the next few years is "imminent and unavoidable." It is the first edition to say so.

"We are now saying this window has closed, but we can open it again by making the overshoot as brief as possible," UNEP Executive Director Inger Andersen told reporters.

The report now measures a different gap. It models a best-case path in which peak warming stays between 1.7°C and 1.8°C, then falls back to 1.5°C or lower by 2100 through deep cuts and carbon removal.

What the UN says it would take

The lowest-overshoot scenario requires global emissions to fall 18% by 2030, 45% by 2035 and 69% by 2040, measured against 2025 levels. It also calls for tripling renewable electricity capacity by 2035 and phasing out coal by 2040.

The report says nothing currently on the table at COP31 comes close. Michael Mann, a climate scientist at the University of Pennsylvania who did not work on the report, said each added fraction of a degree has an "immense" impact in damage, cost and lives lost.

Global emissions were essentially flat last year compared with the year before, the report found.

The U.S. stands out

The U.S. was the only major economy where emissions rose dramatically last year, according to the report. It tied Russia for the highest per-capita emissions among the biggest emitters.

The report attributes the increase to higher electricity demand and to Trump administration policies that favor fossil fuels. Those include orders keeping coal plants open longer than planned, rolled-back vehicle fuel-efficiency standards and the end of tax credits for solar and wind projects.

The administration has withdrawn from the Paris Agreement and is working to pull out of U.N. climate work, arguing the international system imposes unfair burdens on Americans. The EPA now says greenhouse gases do not endanger human health and welfare. The report carries a U.S. government statement saying Washington "does not endorse or agree with its analysis or conclusions." The State Department did not answer NPR's questions, and the administration will not take part in COP31.

The per-capita comparison cuts both ways. China emits more total greenhouse gas than the U.S., but with more than four times the population.

Andersen noted that governments are "scrambling a little bit regarding energy security" amid oil and gas disruptions from the wars in Ukraine and Iran. She said several G20 members, including the European Union, have still sustained emissions reductions.

China arrives with a claim and a bill

China's Ministry of Ecology and Environment says it will send a delegation to Antalya to "actively promote the international climate negotiations." Vice Minister Li Gao told a press conference that China's solar capacity exceeded its coal capacity for the first time this year. He added that China is the top EV producer and leads the world in nuclear capacity when plants under construction are counted.

Li also pressed rich countries on money. He called for "in-depth discussions on a roadmap for developed countries to deliver the $300 billion climate finance goal by 2035 and to triple adaptation finance."

China does not count itself a developed country, even as the world's second-largest economy, so it is not expected to pay into that fund. Breitbart News points to forecasts that China's coal consumption will rise more than 3% this year, partly on data center, EV and air conditioning demand and reduced Middle East LNG shipments during the Iran war. Li did not raise that in his remarks.

The skeptics' case

The Heartland Institute, a think tank that disputes the urgency of the climate agenda, argues that the 1.5°C target may no longer be achievable. It says energy security and adaptation deserve more weight. Its reading of the June preparatory talks in Bonn is that countries are "prioritizing their own industries, electricity security" and fuel supply, not failing out of stubbornness.

Those talks did end in deadlock. Negotiators could not agree on the Mitigation Work Programme meant to push deeper emissions cuts, and the question was deferred to COP31. The EU and Switzerland accused Saudi Arabia, China, India and Russia, among others, of undermining climate science to protect fossil fuel demand.

Heartland also cites Eurocontrol's Small Emitters Tool, which estimates 317 private jet landings at last year's COP30 in Belém, Brazil, produced about 1,541 tons of CO₂.

The host is drilling too

Turkey, the COP31 host, is expanding domestic fossil production. Energy Minister Alparslan Bayraktar said Turkey will soon start drilling a difficult oil-targeted well in the western Black Sea. He expects to double Black Sea gas production capacity by the end of the year.

The Sakarya field supplied 92% of Turkey's domestic gas as of May. Ankara targets 16 to 17 billion cubic meters of annual Black Sea gas by 2028, roughly 80% of what it now imports from Russia.

Energy prices show the pressure behind the talks. Brent crude recently settled at $108.79 a barrel after touching $111.99, a five-month high, as Iranian attacks on Gulf shipping and Houthi strikes on Saudi infrastructure continued.

COP31 opens Nov. 9 in Antalya and runs through Nov. 20. The deferred Mitigation Work Programme dispute and the 2035 climate finance roadmap are both on the agenda, with China, which emits more total greenhouse gas than any other country, attending and the U.S., tied with Russia for the highest per-capita emissions among the biggest emitters, absent.
