First GitLab Duo Agent implementing GSF carbon-aware CI/CD scheduling
A GitLab Duo Agent that measures the carbon footprint of every CI/CD pipeline using the GSF Software Carbon Intensity (SCI) standard — ISO/IEC 21031:2024. It classifies pipeline urgency from commit messages via a fine-tuned INT8-quantized DistilBERT model, autonomously reschedules deferrable pipelines to low-carbon windows, profiles code for energy inefficiencies using Anthropic Claude, and gamifies sustainability with a contributor carbon leaderboard. GreenPipe applies the same optimisations it recommends: its own SCI score is ~0.00079 gCO₂e per pipeline analysis.
GreenPipe automatically posts a carbon report as a GitLab MR comment after every pipeline. No config needed beyond a webhook.
