1Calculation factorsGoogle, fiscal year
All the electricity consumed by Google in one year, data centres and offices, with the carbon and water published by the company.
- Selected reference: In 2025, source Google.
- Consumption includes uses other than AI; AI's share is not isolated in this figure.
- Out of scope: the company's other emissions, including server manufacturing, counted separately.
Sentence to citeGoogle, annual fiscal year: 15.1 MtCO2e, figure published by Google, for 43.6 TWh of electricity.
Origin of the value
AI is included without being quantified separately; consumption more than doubled between 2021 and 2025.

The published figures do not all count the same scope; the scope of each figure is written next to it. Why do the estimates diverge?
