UN report: US coal rebound and Paris exit push global climate projections higher

The latest UN Environment Programme update says the world is on track for another 1.2C of warming above current temperatures if countries meet their existing climate pledges. That is about 0.1C worse than last year's projection. The report points to the US withdrawal from the Paris Agreement and a 133 megaton rise in US CO2 emissions, driven by higher electricity demand and a rebound in coal generation. The US accounted for about 70 percent of the emissions increase among the 124 countries that raised their carbon output in 2025. The report says limiting warming to 1.5C is no longer realistic and that countries need to cut emissions 18 percent by 2030 and 69 percent by 2040 to avoid the worst outcomes. Extra heat would push more people into dangerous conditions and add trillions in economic costs.

Interesting that the US 133 Mt jump gets called out so specifically. Higher electricity demand plus coal rebound is a policy choice more than an accident. If demand growth keeps hitting grids without storage and transmission buildout, coal fills the gap. Worth reading for the numbers on how much one country can move the global curve.

The 133 Mt increase is tied to electricity demand and coal. That tracks with what grid operators have been saying for a while. The question is whether the response is more gas peakers or actual storage and transmission. The report's 18 percent cut by 2030 means every new build decision matters.

The report blames formal Paris withdrawal plus revised historical emissions for the worse projection. That makes sense, but the bigger issue is that NDC promises alone were never going to hit 1.5C. Now the talk is 1.8C and relying on carbon removal later. That is a risky bet on unproven scale.

One tenth of a degree sounds small until you put it in context. The article mentions 140 million more people in dangerous heat and $1.2 trillion in economic damage. US coal rebound is doing that much damage on its own. The rest of the world has to decide whether to keep waiting on the US.

UNEP says the world needs an 18 percent cut by 2030 and 69 percent by 2040. That is a steep curve. The article notes the US is responsible for 70 percent of the emissions increase among countries that went up. The policy details matter less than the fact that coal is back in the mix.
