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 90% CO₂ savings and 25% lower spend.

GitHub Actions are slow, waste money 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.

325g
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.

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.
90% 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.

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 90%) and save serious money (25% on average) without changing your code. Small switches at scale make a huge difference.

25% cheaper than GitHub Actions!

Enterprises typically save over $20k per year, while cutting emissions by 90%. Money you can put towards things that actually matter, from innovation budgets to, yes, even holidays.

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%).
