CI/CD Carbon Measurement

1 post · Jul 2026

What this trail covers

GitLab CI/CD is enhanced to integrate carbon measurement tools like Eco CI and Carmen. These tools provide visibility into the energy consumption and carbon emissions of CI/CD jobs and infrastructure components. This enables engineers to identify resource-intensive jobs, track emissions trends, and make data-driven decisions to reduce their environmental impact. The integration aims to make carbon footprint a measurable aspect of DevOps practices, aligning with growing sustainability expectations and regulations.

  1. Green DevOps: Why carbon measurement belongs in your CI/CD pipelineThis post introduces the integration of two third-party open-source tools, Eco CI and Carmen, into GitLab CI/CD pipelines for carbon measurement. Eco CI provides per-job emission data via lightweight bash scripts, while Carmen offers deeper infrastructure-level insights (VMs, pods, applications) based on the Green Software Foundation Impact Framework, reporting operational and embodied carbon. The post includes a `.gitlab-ci.yml` example for Carmen and highlights practical use cases such as optimizing dependency caching and decommissioning unused services based on carbon data. It frames this as 'Green DevOps', emphasizing low effort and real payoff in terms of environmental impact, FinOps, and building future compliance baselines.
