GitHub Actions

It's a one-line code change!

Global grids are dirty. Default GitHub Actions are stuck in high-emission regions. CarbonRunner shifts jobs in real time to the greenest, cheapest energy regions — delivering up to 10x CO₂ savings and 25% lower spend.

GitHub Actions are slow, expensive and are powered by fossil fuels.

Every build you run on GitHub-hosted runners comes at a premium — both in cost and emissions. Most workloads run on fossil-fuel heavy grids, and the waste adds up fast.

437g
CO₂eq/kWh

The current global grid intensity average.

Full of lots of fossil fuels.

330g
CO₂eq/kWh

The current average grid intensity of Github runners.

Where over 10 million jobs are run each day.

Fun fact... right now CarbonRunner is a whopping 12x greener than default GitHub Actions.

The world's first carbon-aware CI/CD infrastructure.

4 Features for Faster, Cheaper, Greener Workflows.

Multi-cloud resilience & cost savings: CarbonRunner automatically shifts across providers to maximise reliability and find the cheapest compute and zero lock-in.
Region preference & control: Decide where your jobs run, with full sovereignty over data and compliance. Or let us handle it with our carbon-aware infrastructure.
Faster builds than GitHub Actions: Run your jobs faster than GitHub Actions. With a one-line swap in your workflow, you’ll save developer time, speed up releases, and ship with confidence.
10x fewer emissions, by default: TCarbonRunner is the world’s first carbon-aware infrastructure — with automatic carbon accounting and ESG-ready reporting built in. Your pipelines get greener without extra effort.

Built for enterprise scale.

Swapping over to CarbonRunner we've seen enterprise customers typically save over $20k per year, while cutting emissions by 10x - That's a whopping 25% saving.

Based on 500,000 CI/CD minutes per month on a 4 vCPU GitHub runner. GitHub Actions: $86,400/year (450k billable minutes @ $0.016). CarbonRunner: $64,800/year (450k billable minutes @ $0.012). Annual saving: $21,600 (25%).

Frequently asked questions

Got a questions for us? Please feel free to reach out to our customer support team.

Can you shift my AI training models?: Yes. CarbonRunner isn’t limited to CI/CD — we can shift AI training workloads, batch processing, and data pipelines to the cleanest, cheapest regions in real time.
What about Bitbucket, GitLab, and CircleCI?: Absolutely. CarbonRunner integrates with all major CI/CD platforms — not just GitHub Actions. Wherever you run your pipelines, we make them faster, cheaper, and greener.
Can CarbonRunner be used without GitHub?: Yes, we accept other sources like BitBucket and Gitlab. Also workloads through API-submitted jobs, Docker containers, and job specs.
Why does shifting CI/CD jobs even matter?: CI/CD runs constantly in most teams — thousands of minutes every month. On default grids, those jobs burn through cash and carbon. By shifting them to the cleanest, cheapest regions, you cut real emissions (up to 10x) and save serious money (25% on average) without changing your code. Small switches at scale make a huge difference.
