Cryptocurrencies rely on energy‑intensive consensus mechanisms, most notably proof‑of‑work, which require computers to solve complex mathematical puzzles. Each solved puzzle validates a block of transactions and secures the network, but it also consumes electricity that often originates from carbon‑producing sources.
The ecological impact of a cryptocurrency can be estimated by multiplying three key variables: the number of transactions processed, the average energy consumed per transaction, and the carbon intensity of the electricity used. This approach translates digital activity into a tangible amount of CO₂ emissions, making the hidden environmental cost visible.
By understanding and monitoring these variables, users, developers, and policymakers can make informed decisions to reduce the carbon footprint—such as improving transaction efficiency, switching to renewable energy, or adopting less energy‑hungry consensus algorithms.
N = number of transactions per day
E = energy per transaction (kWh)
I = carbon intensity of electricity (kg CO₂/kWh)
