Illuminating the Energy Footprint of WEB3 Technology
Every Proof-of-Work transaction has a real carbon cost. WEB3CO2 measures it from live network data — and reveals how radically that cost differs between blockchains.

Frequently Asked
How do you calculate carbon per transaction?
We estimate the number of Antminer S21-equivalent ASICs from each network's hashrate, multiply by their power draw to get whole-network energy, then divide by throughput (transactions per second) and apply a grid-average emission factor of 0.5 kg CO2 per kWh. The full derivation is above.
Where does the live data come from?
BTC and BCH statistics come from Blockchair; BSV statistics come from WhatsOnChain. All figures reflect a rolling 24-hour window and refresh once daily.
Why is BSV so much more efficient?
BSV processes far more transactions per block, so the same mining energy is amortised across vastly more transactions — dramatically lowering the energy and carbon attributable to each one.
