Updated Carbon Methodology for the AWS Customer Carbon Footprint Tool

AWS has updated the Customer Carbon Footprint Tool (CCFT) with three key improvements to help customers track their carbon emissions:

• Enhanced data access through AWS Billing and Cost Management Data Exports service
• More granular carbon emissions data by AWS Region
• Updated, independently-verified carbon methodology (version 2.0)

Key methodology changes include:

• Allocating emissions from unused server capacity to all customers
• Improved emissions allocation for services without dedicated hardware
• Including overhead emissions from data center operations

Customers will see updated carbon emissions estimates for AWS usage starting January 2025, supporting their sustainability journey and AWS's commitment to reach net-zero carbon by 2040.
