The report, marking ten years since the Paris Agreement’s adoption, concludes that even with full implementation of all existing pledges, global temperatures are projected to rise between 2.3°C and 2.5°C this century. Should current policies persist, global warming could potentially reach 2.8°C.
United Nations Secretary-General Antonio Guterres, in his video message posted after the report launch on November 4, said that the new Emissions Gap Report, issued by the United Nations Environment Programme, is clear and uncompromising. If nationally determined contributions, the national action plans on climate, are fully implemented by 2035, global warming would reach 2.3 degrees Celsius, down from 2.6 degrees in last year’s projections. That is progress, but nowhere near enough.
He said that the current commitments still point to climate breakdown. Scientists tell us that a temporary overshoot above 1.5 degrees is now inevitable, starting at the latest in the early 2030s. And the path to a livable future gets steeper by the day. “But this is no reason to surrender. It is a reason to step up and speed up. 1.5 degrees by the end of the century remains our North Star. And the science is clear: the goal is still within reach. But only if we meaningfully increase our ambition. Our mission is simple, but not easy,” he said.
Only about one-third of countries have submitted new or updated climate pledges (NDCs) by the September 2025 deadline. The report warns that despite some progress in renewable energy deployment, overall global emissions reached 57.7 gigatons of CO₂ equivalent (GtCO₂e) in 2024—a 2.3 percent increase from 2023, the steepest annual rise in over a decade.
According to UNEP, deforestation and land-use change accounted for more than half of the increase in 2024’s emissions, with fossil fuels contributing 36 percent. The G20 nations remain responsible for 77 percent of total global emissions, and only the European Union recorded a decline last year. India and China saw the largest absolute increases, while Indonesia registered the fastest relative growth.
Despite the Paris Agreement’s requirement that all parties submit new or revised NDCs by early 2025, only 60 parties, covering 63 percent of global emissions, have done so. Of these, just 13 updated their 2030 targets. Most new NDCs offer little improvement in ambition, with many missing commitments to double energy efficiency or triple renewable energy capacity by 2030. “Costs are falling, investments are rising, innovation is surging, and clean power is now the cheapest source of electricity in most markets and the fastest to deploy. It strengthens energy security, cuts pollution, and creates millions of decent jobs. Leaders must seize this moment and waste no time,” Guterres said.
He added that tripling renewables and doubling energy efficiency by 2030, building modern grids and large-scale storage, and ending all new coal, oil and gas expansion in a just and equitable manner. “The clean energy revolution must reach everyone, everywhere. But developing countries face crippling capital costs and a fraction of global investment,” he added.
UNEP’s analysis indicates that the new NDCs narrow the emissions gap for 2035 only marginally. The world would still emit 12 GtCO2e more than what is consistent with a 2°C pathway and 23 GtCO2e above the level required for 1.5°C. The gap widens further by 2050 unless countries drastically change course.
Overshoot of 1.5°C Now Inevitable
The report warns that global temperatures are set to exceed the 1.5°C limit within the next decade, with 2024 already marking the hottest year on record at 1.55°C above pre-industrial levels. The remaining carbon budget for a 1.5°C future without overshoot is just 130 GtCO₂, which is enough for barely three more years of current emissions.
Inger Andersen, Executive Director of UNEP, said the findings show governments have “missed the target for a third time.” She called the withdrawal of the United States from the Paris Agreement a major setback that would add roughly 0.1°C to projected warming.
“The task now is to make this overshoot as brief and shallow as possible,” Andersen said. “Every fraction of a degree matters. Each 0.1°C increase brings more droughts, floods, and losses, especially for the poorest.”
What Needs to Happen
To have a 66 percent chance of returning global warming to 1.5°C by 2100, the world must cut 2030 emissions by 26 percent and 2035 emissions by 46 percent compared with 2019 levels. This would require reducing global greenhouse gas output to about 32 GtCO₂e by 2035.
The “rapid mitigation from 2025” scenario explored in the report shows that immediate and deep reductions starting next year could still limit peak warming to around 1.7–1.9°C before gradually returning to 1.5°C by the end of the century. But UNEP warns that each year of delay makes the path “steeper, costlier, and more disruptive.”
The report emphasizes two imperatives: implementing aggressive near-term mitigation to minimize temperature overshoot and scaling up carbon dioxide removal (CDR) technologies to reach net-zero and eventually net-negative emissions.
Unequal Progress and Missed Opportunities
Seven G20 members are on track to meet their current NDC targets, but most are far from achieving their net-zero pledges. Many developing countries still lack financing and technical support to implement their climate commitments. The report urges developed nations to provide “unparalleled increases in climate finance” and to reform international financial systems to make green investments accessible.
Despite setbacks, UNEP highlights that 70 percent of global emissions are now covered by net-zero pledges, a sharp increase from zero in 2015. Falling costs of wind and solar energy, along with advancements in battery storage, have made clean energy transition more viable than ever.
“Climate action is not charity,” Andersen said. “It is self-interest. It delivers jobs, energy security, and economic resilience.”
Science and Legal Mandates
The report also references the July 2025 advisory opinion of the International Court of Justice, which ruled that states have legal obligations to protect the climate system under human rights law. It reaffirmed that limiting warming to 1.5°C remains the primary goal of the Paris Agreement, despite temporary exceedance.
UNEP scientists caution that even brief overshoots of 1.5°C could trigger irreversible tipping points, including the collapse of the West Antarctic ice sheet and thawing of permafrost releasing methane. Each 0.1°C rise beyond current levels increases risks of extreme weather, biodiversity loss, and health impacts, particularly in vulnerable regions.
Path Ahead to COP30
The findings come ahead of COP30 in Belém, Brazil, where nations are expected to present enhanced NDCs. UNEP urges governments to treat the conference as a turning point.
“The Paris Agreement has driven progress, but ambition and delivery have lagged,” the report states. “Each missed opportunity now adds to future costs, instability, and suffering.”
Guterres said that COP30 in Belém must be the turning point, where the world delivers a bold and credible response plan to close the ambition and implementation gaps, to mobilize USD 1.3 trillion a year by 2035 in climate finance for developing countries, and to advance climate justice for all. “The path to 1.5 degrees is narrow but open. Let us accelerate to keep that path alive for people, for the planet, and for our common future,” he said.
The 2025 report was prepared by 39 scientists from 21 institutions in 16 countries, coordinated by UNEP’s Copenhagen Climate Centre. It states that while 1.5°C is still technically achievable, the window is “narrow and closing fast.”
“Global warming will exceed 1.5°C, very likely within the next decade,” it says. “The challenge now is to ensure that this overshoot is brief and reversible. Every year, every policy, every ton of CO2 counts.”
