At least a 90% reduction in carbon emissions.

Swapping over to use our carbon-aware Github Actions Runner is so simple; it's a one-line code change! Once you've done this we will find the most low-intensity regions to run your jobs. A huge win for the planet.

We've saved
0.00kg
of CO2 so far!

In the last 7 days

Every time a job runs, we track the carbon savings, providing a clear and measurable impact for our users and as a service.

So far, this collective effort has resulted in substantial emission reductions, showcasing the power of technology to drive positive environmental change.

We run jobs in 45 of the lowest CO2regions.

Carbon-aware

Finding the lowest CO2 regions by default

Our average CI job runs at an impressive 48gCO2eq/kWh. Achieving a 10x reduction in carbon emissions per job compared to traditional Github Actions Runners.

Multiple regions

Optimizing Across Regions for Maximum Sustainability

Running in over 45 low CO2 regions. We gather live energy data to shift workloads to the lowest carbon intensity regions. This optimizes energy use, reduces emissions, and supports sustainability without sacrificing performance.

Flexible

Power Your Workloads with Providers You Trust

Running your jobs on different providers AWS, Azure, Google GCP (coming soon) and Oracle OCI (coming soon)

Deploy smarter

It's a one-line code change!

Once you've made the change, we select the most environmentally & cost-effective regions to run your AI, CI, Video and Gaming jobs.

Only using servers in regions with a grid intensity less than 100gCO2eq/kWh.

We're on a mission to reduce the carbon emissions of the internet.

When you swap over to CarbonRunner we'll use a server in the most eco-friendly region around the world. This small change sees at least a reduction in carbon emissions of equivalent Github Actions runners.
