This article explains how to establish a sustainability proxy metrics data pipeline on AWS to track and optimize cloud efficiency across multi-account environments.

• Set up centralized metrics pipeline using AWS Cost and Usage Reports and CloudWatch data
• Implement multi-account governance with AWS Control Tower and Organizations structure
• Establish resource tagging strategy for granular metric scope definition
• Ingest business metrics into central S3 metrics lake for normalization calculations
• Create dashboards showing compute usage ratios, instance types, and adoption metrics
• Extend existing cost showback processes with sustainability proxy metrics
• Start with high-impact services like EC2 where you control efficiency decisions
• Share dashboards with application teams for operational reviews and decision-making
• Celebrate optimization wins with leadership visibility to foster sustainable behavior

The post provides a framework for organizations to measure cloud efficiency systematically and drive sustainability improvements through data-driven insights and team engagement.
