US carbon emissions rebound in 2025, fueled by heating demand and data-center growth

TL;DR Summary
U.S. greenhouse gas emissions rose about 2.4% in 2025 versus 2024, ending a decade-long decline as a cold winter boosted heating demand and electricity use from data centers and crypto mining, with higher natural gas prices boosting coal power; solar surged 34% and zero-carbon sources supplied roughly 42% of electricity, though experts warn the uptick could foreshadow more emissions if fossil fuels remain dominant and Trump-era rollbacks haven’t yet taken effect.
