A new UN Environment Programme report says the world is falling further behind in the fight against climate change. If countries meet their current promises, the planet would still warm about 2.6 degrees Celsius above pre-industrial levels by 2100, well past the Paris Agreement targets. The report specifically points to the United States, where emissions rose by 133 megatons of CO2 equivalent in 2025, driven by higher electricity demand and a rebound in coal generation. That increase accounted for about 70% of the net rise from all countries that saw emissions grow. The report also attributes roughly one-tenth of a degree Celsius of added end-of-century warming to the US withdrawal from the Paris Agreement. UN officials now say the 1.5 degree goal is out of reach and are focusing on limiting warming to around 1.8 degrees. The findings highlight how domestic energy policy and international commitments are tightly linked, and they add fresh context for anyone tracking carbon markets, grid investments, or the pace of coal retirement.
