# What do AI energy and water disclosures actually tell you?

A company-wide power or water report describes infrastructure and practices within a stated boundary. It does not automatically measure the energy or water for a particular model, app, or request. Check the reporting year, metric, region, and workload before comparing numbers.

## What kinds of water information do providers publish?

Water withdrawal, consumption, water-use effectiveness, and replenishment measure different things. WUE describes water intensity per unit of data-center IT energy, not water per prompt. Replenishment describes restoration projects, not a reduction in local withdrawals. [AWS publishes data-center and regional WUE ↗](https://sustainability.aboutamazon.com/products-services/aws-cloud?waterType=true); [Google reports freshwater use and replenishment ↗](https://sustainability.google/operations/); [Microsoft reports fleet water intensity ↗](https://blogs.microsoft.com/blog/2026/06/24/inside-microsofts-two-decade-push-to-cut-water-intensity-while-scaling-for-growth/); [Meta reports stress-region restoration ↗](https://about.fb.com/news/2025/12/advancing-water-stewardship-in-metas-data-center-communities/).

## Does a report measure one chatbot or AI request?

Product-level impact needs a known serving route, location, model, workload, and measured method. Company totals do not allocate use to a prompt. The directory’s energy practices score assesses documentation and controls; it is separate from water disclosure and does not estimate a request footprint. Check the scope for [ChatGPT](https://ethicalstack.ai/products/chatgpt/), [Gemini](https://ethicalstack.ai/products/gemini/), [Microsoft Copilot](https://ethicalstack.ai/products/copilot/), and [Grok](https://ethicalstack.ai/products/grok/).

## How can I compare providers fairly?

Compare the same reporting year and boundary: direct operations or full value chain, company or named facility, withdrawal or consumption, and measured or estimated data. Note whether high-stress regions are disclosed and whether the provider maps a service to a location. If the route is unknown, the product-level answer remains unknown. Browse [compare providers](https://ethicalstack.ai/compare/providers/) and read each profile’s environmental sources.
