UN sets steep emission cuts to reverse 1.5C overshoot by end of century

🗞️ Driving the news: The UN says global greenhouse gas emissions must fall by nearly 6% annually to give the world a good chance of returning global warming to the Paris Agreement’s 1.5°C limit by 2100
• According to the 2026 Emissions Gap Report, decades of insufficient climate action have made a temporary overshoot unavoidable, but a return to the target remains possible

🔭 The context: UN Secretary-General António Guterres said the world can no longer prevent temperatures from exceeding 1.5°C above pre-industrial levels, warning that the consequences are already severe
• The report, published by the UN Environment Programme (UNEP), highlights the scale of emissions reductions needed to reverse that overshoot by the end of the century

🌍 Why it matters for the planet: Exceeding 1.5°C increases risks to ecosystems, biodiversity, food and water security, and communities exposed to extreme heat and other climate hazards
• Rapid emissions cuts could limit further warming, while returning temperatures to 1.5°C would not necessarily undo all impacts caused during the overshoot

⏭️ What’s next: Governments would need to accelerate emissions reductions across energy, transport, industry and land use to approach the required annual decline
• The feasibility of returning to 1.5°C by 2100 will depend on the pace and scale of global action, as well as sustained emissions cuts over time

💬 One quote: “The world could no longer avoid overshooting the 1.5C limit,” said UN Secretary-General António Guterres, while maintaining that returning to the target by the end of the century remains possible

📈 One stat: Nearly 6% per year — the annual reduction in global greenhouse gas emissions the report says is needed to give the world a good chance of returning to the 1.5°C limit by 2100
