AWS awsaccountbilling documentation change
Summary
Updated methodology documentation for Customer Carbon Footprint Tool with expanded standards references (GHG Protocol, ISO 14040/14044), third-party verification details, regional emission examples, and structural improvements
Security assessment
Changes focus on environmental reporting methodology improvements and documentation structure. No security vulnerabilities, access controls, or data protection mechanisms are mentioned. Updates relate to emissions calculation transparency rather than system security.

This means it factors in Amazon enabled renewable projects on the grids where the customer footprint is being estimated. Because we use the market-based method to calculate Scope 2 emissions, only purchased renewables on the grid where your workloads are running are included in the carbon footprint estimates. Estimates factor the grid mix of the AWS Regions where you run your workloads, following GHGP guidance.

There are others where the low usage results in higher emissions. For carbon reports, EMEA Regions are often shown as under represented in estimates since there are more renewables on the grid. APAC Regions are often shown over represented in estimates. This is because sourcing renewable energy is difficult.
