UNEP's latest Emissions Gap Report says the window to hold warming at 1.5C is effectively closed. To keep the overshoot near 1.7C, global greenhouse gas emissions need to fall 18% by 2030 and 45% by 2045. Current policies point to roughly 2.8C of warming, and even fully implemented pledges would land near 2.6C. That gap between what countries promise and what they actually do is the core problem. Renewable energy is growing fast, but emissions in 2025 stayed nearly flat. UNEP points to methane as a near-term lever, since it warms about 80 times more than CO2 over a short horizon. The report also warns that every five years of current emission levels adds another 0.1C of projected warming. The next global stocktake is set for 2028, but IPCC report delays could weaken that review. For carbon market participants, the report reinforces demand for projects that deliver verifiable cuts and removals. With overshoot likely, avoided emissions and direct capture both gain value. The article is a useful summary of the UNEP findings, though it does not detail how the 18% cut gets financed or enforced.
