US leads global CO2 emissions increase in 2025, report finds

Global energy-sector carbon emissions rose 1.1% to 35,806 million metric tons, with the U.S. accounting for about a third of the increase as coal consumption jumped 10% on higher gas prices. Renewable power generation still climbed 9.1%, led by a 30% surge in solar, but electricity demand rose faster than supply at 3% year-on-year, driven by EVs, data centres and AI. The report points to a mixed energy backdrop: accelerating clean power growth alongside a temporary coal rebound and firmer fossil-fuel demand.

Analysis

The near-term market read-through is not simply “more emissions,” but a regime shift in marginal fuel economics: if gas volatility keeps power generators bidding back into coal, the clean-fuel transition becomes less linear and more policy- and price-sensitive. That is bearish for names exposed to pure-play decarbonization narratives, while simultaneously supportive of integrated energy, thermal coal logistics, and utility fleets that can flex between fuels. The second-order effect is that any sustained gas strength widens the earnings dispersion across utilities, with generators lacking hedges or dual-fuel optionality likely to see the sharpest margin pressure over the next 2-4 quarters.

The cleanest alpha is in the lag between policy rhetoric and physical system constraints. Renewables are still growing fast, but the report underscores that electricity demand is outrunning supply, which means intermittent additions do not fully displace firm capacity in the medium term. That keeps a bid under gas infrastructure, grid equipment, and power-market volatility, while making “green beta” vulnerable if investors had been extrapolating straight-line coal displacement; the market may need to re-rate away from aggressive 2026-2027 transition assumptions.

The AI/data-center angle matters because it raises power demand exactly where the grid is already tight, creating a structural tailwind for dispatchable generation, transmission, and thermal fuel transport. A contrarian view is that higher coal burn may be self-limiting: if gas prices moderate or policy support accelerates permitting and storage buildout, the current emissions rebound can reverse faster than consensus expects. But until then, the macro setup favors assets that monetize power scarcity over those that depend on a clean-electrification narrative.
