Cryptocurrency Footprint Historical Model

Archived record of a discontinued fixed-factor cryptocurrency footprint model; it is not a current emissions calculator.

Published

Calculator archived: The former interactive fixed-factor model is disabled and does not provide current cryptocurrency energy or emissions estimates.

Archived cryptocurrency footprint model

Archived historical, non-current snapshot — dated July 10, 2026 (2026-07-10). The fixed asset factors, generic 0.40 kg CO2e per kWh electricity factor, and 2021–2023 year adjustments described below belong to a discontinued model and are not a current method for estimating cryptocurrency energy use or emissions. Consult a network-specific energy dataset and the applicable electricity-emissions inventory for current research.

This page is a historical, non-current record of a discontinued calculator. The interactive model has been disabled. It must not be used to estimate the present energy use or greenhouse-gas emissions of a cryptocurrency, network, transaction, holding, miner, or metal.

Historical scope

The retired model used fixed asset factors, a generic electricity factor of 0.40 kg CO2e per kWh, and year adjustments limited to 2021–2023. Those assumptions were not tied to a documented network, geography, grid region, hardware fleet, or accounting boundary. Its metal-unit selector also did not perform physical unit conversion.

The historical example is 100 kWh × 0.40 kg CO2e/kWh = 40 kg CO2e, explicitly using a hypothetical 2021 eGRID factor. This illustrates multiplication only; it does not validate that factor for a cryptocurrency or make the old model current.

Why the calculator is archived

Cryptocurrency electricity use and emissions vary with consensus design, network activity, equipment, location, time, and electricity mix. The former fixed-factor interface could imply unsupported currency and precision. The old model is not suitable for current estimates.

For current research, consult a network-specific energy dataset and the applicable versioned electricity-emissions inventory directly. No current result or freshness claim is provided here. For current scenario-style estimates in adjacent areas, see the Home Energy Efficiency Calculator and Solar Panel Carbon Offset Calculator, or the Flight Emissions Calculator for a travel-footprint worksheet.
