UNEP declares 1.5°C lost and calls for 69% emission cuts by 2040
The UN Environment Programme's report is titled "The Point of Return". Its verdict: the chance to close the 1.5°C gap with limited overshoot "has been lost", so the aim is now to stay under 2°C and come back to 1.5°C by 2100.
Countries' current pledges would cut emissions 5 to 8% by 2030, against the 18% UNEP says is needed. Getting back under 1.5°C also means pulling about 320 gigatons of CO2 out of the air by 2100, roughly eight times what the world emitted in 2024.
A climate-tech worker with 12 years in the field answered with a plea for stamina: the physics never changes, so neither does the task.
What "overshoot" now means
UNEP's 2026 Emissions Gap Report concludes that limiting warming to 1.5°C by 2100 is no longer achievable, and that exceeding it is imminent. The new priority is to hold warming below 2°C and then return to 1.5°C before the century ends. UN Secretary-General António Guterres asked for cuts of close to 6% every year until 2035.
| Year | Cut needed vs 2025 | Cut if all current pledges are met |
|---|---|---|
| 2030 | 18% | 5–8% |
| 2035 | 45% | 11–15% |
| 2040 | 69% | not given |
The toolkit: tripled renewables and 320 gigatons of removal
Renewable capacity must triple by 2035 against 2025. The shares of coal, oil and gas in energy production must fall by 55%, 15% and 5% by 2035, and by at least 75%, 30% and 35% by 2040. Carbon removal fills the rest: about 320 gigatons of CO2 by 2100.
The report finds some good news. Renewable capacity has grown three times faster than expected since 2015, solar PV seven times faster, and coal and oil supply have grown more slowly than projected. UNEP still calls progress insufficient on fossil fuels and deforestation.
The thread: stamina, a carbon price, and a harsh word for climate tech
The most-replied comment came from a climate-tech worker.
"The physics, however, don’t change, and neither does the task in front of us." — a climate-tech worker with 12 years in the field
Replies went for the system rather than the individual. One commenter wanted a carbon price:
"If the politicians focused on that then the forces of capitalism and startups would be unleashed to bring down co2."
A harsher view came from inside the industry.
"Unfortunately my conclusion is that Climate Tech companies in general have been delusional thinking the mission is enough and there is no requirement to be a business." — a climate-tech engineer
His advice to anyone moving into the field: go in with eyes open, and pick companies that could survive without the mission.
