Overview
- Building fuel use jumped 6.8% as colder weather increased demand for heating, reversing recent declines in that sector.
- Power‑sector emissions rose 3.8% as rapid growth in electricity use from data centers and cryptocurrency mining coincided with pricier gas that lifted coal generation about 13%.
- Total U.S. greenhouse gases reached roughly 5.9 billion tons of CO2‑equivalent, about 139 million tons more than 2024, outpacing real GDP growth of 1.9%.
- Solar generation surged about 34% and zero‑emitting sources supplied a record near 42% of U.S. power, while transportation emissions were roughly flat despite record travel.
- Researchers said recent federal rollbacks had little measurable effect on 2025 totals but could weigh on future reductions, and reduced federal data collection may complicate tracking.
