Blockchain’s carbon footprint is real—proof-of-work mining consumes as much electricity as a small country. Yet the industry is evolving. Proof-of-stake slashes energy use by >99%, layer-2 roll-ups reduce on-chain load, and many miners now run on solar and wind. Carbon-offset programs and green-coin projects turn waste into credits, showing sustainability can coexist with decentralization.
