# Water withdrawals The water withdrawals data in the AWS Sustainability service quantifies customer-specific water withdrawals associated with the use of AWS cloud services and covers the full range of said services. The methodology allocates total water withdrawal from AWS data center operations to individual customer accounts based on their proportional cloud service usage. Total water withdrawal is defined as the total volume of water taken from any source (e.g., surface water, groundwater, rainwater, third-party/municipal supply, and reclaimed water) for data center operations, regardless of whether it is eventually returned to the environment. The definition for total water withdrawal used in the AWS Sustainability service aligns with the [CDP technical note on water accounting](https://cdn.cdp.net/cdp-production/cms/guidance_docs/pdfs/000/001/561/original/CDP-technical-note-water-accounting-definitions.pdf) and [GRI 303:2018](https://globalreporting.org/pdf.ashx?id=12488). ## See also * **Skills for AI coding assistants (optional).** AWS publishes reusable skills for AWS Sustainability.
