Carbon Ledger
What every pipeline costs, in grams.
The carbon steward meters every CI job of this project, turns the timings into a Software Carbon Intensity score, and audits the pipeline for work it does not need to do.

Latest pipeline
Every job is metered in its after_script; the footprint is energy times the grid's intensity plus a share of the runner's manufacturing.
Footprint by job
Grams of CO2e per job, highest first. Hover or focus a bar for its runner time and energy.

What the carbon steward found
A deterministic audit of the CI file against what the last pipeline measured. The steward opens an optimisation merge request only when the saving pays back three times its own footprint.

Estimate a CI job
The same formula the pipeline uses, pre-computed per runner and region, so nothing leaves your browser.
Three greenest regions for this job
Grid intensity by region
Grams of CO2e per kWh on the local grid of every Google Cloud region, cleanest first. Where a job runs can matter more than how long it runs.
