Proof-of-Work vs Proof-of-War
Bitcoin's Proof of Work (~90 Mt CO2e/yr): =
Fiat's Proof of War (~2,750 Mt CO2e/yr): ============================ (28 units)
(Scale: Each "=" represents approx. 100 Million tonnes CO2e/year)
Bitcoin (Proof of Work): Est. CO2e from electricity used for Bitcoin's Proof of Work – the computational effort required to secure the network and validate transactions.
Fiat (Proof of War - Military Proxy): Est. CO2e from the global military system – argued by some to represent the enforcement cost underpinning geopolitical/economic systems associated with fiat currencies.
Sources / Estimates Basis:
BTC: ~90 Mt CO2e/yr (e.g., CCAF [Cambridge Centre for Alternative Finance] est. c. 2022).
Military: ~2,750 Mt CO2e/yr (SGR [Scientists for Global Responsibility] / CEOBS [Conflict and Environment Observatory] est. 2022).
