Bitcoin (1 Tx) vs Ethereum (Tx)

This comparison matters because Bitcoin and Ethereum represent very different network energy profiles, especially after Ethereum's move away from proof-of-work.

Summary

When comparing Bitcoin (1 Tx) and Ethereum (Tx), Bitcoin (1 Tx) generates significantly more CO2 emissions per hour (400000g) than Ethereum (Tx) (13g). Both applications rely on devices, networks, and server infrastructure, which all contribute to their environmental impact.

Why the gap happens

Consensus design affects the total network energy requirement.
Transaction attribution is still debated, so use the result directionally.
This is a systems comparison more than a device-use comparison.

What to act on first

If crypto is part of the footprint you are trying to cut, network choice matters more here than typical browser or app optimizations.

Bitcoin (1 Tx) is currently modeled at 399987g CO2 more per unit of use than Ethereum (Tx).
