What an AI request costs

Electricity, carbon, and water, for your actual use. The same formulas and data as the open-source calculator. Orders of magnitude, not measurements.

The tool

Pick a model and a monthly volume of requests, or start from one of three examples (a tourist office chatbot, writing listing descriptions, an assistant for a team of ten). The page shows the carbon, electricity, and water per request and over a year, the breakdown by item, and how the same use compares across the method’s 38 models.

Method and data: Impact’IA, calculator and methodology guide v1.0 (July 2026), by the SNCF group’s digital department, Resilio, and Wavestone, under the CC BY-NC-SA 4.0 license.

The tool is in French.
