summary
Claims a reproducible per-release KPI based on the Green Software Foundation Software Carbon Intensity (SCI) spec, implemented with a simple pipeline that deploys workloads to controlled bare-metal testbeds, measures power with Kepler, and posts SEI scores to a shared observability stack. Demonstrates idle vs loaded measurements, cites KEDA’s carbon-aware scheduling on Azure as an early adoption, and flags hard problems: the functional scaling factor R, embodied carbon math, and reliance on carbon-mix APIs (WhatTime / ElectricityMap) that often require paid access.
