Cryptocurrency Footprint Calculator

Estimate the energy and CO2 per transaction.

CO2 per transaction 332.5

Tonnes per 1000 tx (t) 332.5

Formula: CO2 = kWh * grid intensity / 1000

Step-by-step with your numbers:

1. Values used:

2. Energy per transaction = 700 kWh

3. Grid CO2 intensity = 475 g/kWh

5. CO2 per transaction = 332.5

6. Tonnes per 1000 tx = 332.5t

Did we solve your problem today?

Proof-of-work blockchains consume large amounts of electricity per transaction.

The math behind it

CO2 per transaction = energy used x grid carbon intensity. The energy figure varies widely by blockchain.

700 kWh at 475 g/kWh emits about 333 kg CO2.

Is all crypto this intense?

No — proof-of-stake chains like Ethereum post-merge use a fraction of the energy.
