Carbon-aware Github Actions for the greenest workloads.

Using real-time data we ensure your Github Actions run on low-carbon energy whenever possible, helping lower carbon footprints without sacrificing performance.

"Carbon-awareness is about making smarter choices to reduce emissions by shifting workloads to places where the energy grid is cleanest, most low-carbon."

Dryden Williams – CEO of CarbonRunner

Why Carbon-Aware Matters

The internet relies heavily on fossil fuels, with many of the 8,000+ data centers located in hot, water-scarce regions—environments that increase operational strain and, in turn, produce significant carbon emissions.

By embracing carbon-awareness, we can significantly reduce the environmental impact of our operations. This means being highly selective about the data centers we use, prioritizing sustainability by dynamically adjusting operations to align with cleaner energy sources.

A data center's carbon intensity reflects how much CO₂ is emitted to generate one kilowatt-hour of electricity. By choosing facilities with a carbon intensity of less than 100g CO₂/kWh, we ensure that your workloads run in the most environmentally friendly settings available.

  • Reduced Carbon Footprint: Dramatically lower the environmental impact of your digital operations.
  • Support Renewable Energy: Prioritize data centers powered by wind, solar, and hydroelectric energy.
  • Global Compliance: Align with corporate sustainability goals and international climate initiatives.

How CarbonRunner Enables a Carbon-Aware Internet

We actively monitor real-time carbon intensity data from grids around the world. Here's how our system works:

  • Real-Time Intensity Tracking: Using live grid data, we identify regions where electricity is generated using renewable sources.
  • Intelligent Job Routing: Workloads are dynamically routed to data centers in regions operating below 100g CO₂/kWh.
  • Always Carbon-Aware: If no regions meet the criteria at a given moment, CarbonRunner queues jobs until the system identifies a green region, ensuring eco-conscious operations.

Why do you always say "low-carbon" and not"renewable"?

We try to be as conscious as possible with the words we use around the environment.

We use "low-carbon" as it refers to an energy mix including nuclear. "renewable" normally excludes nuclear and is an energy source that "naturally replenish over time".

Our intelligent Github Actions runner doesn't mind if it's nuclear just as long as it dosn't produce carbon emissions!

Make a Meaningful Impact

Every workload you run with CarbonRunner contributes to a cleaner planet. Our Github Actions Runners reduce emissions by at least 90%. By choosing only the greenest servers, you:

  • Support the growth of renewable energy: Help drive global renewable energy adoption.
  • Lower global CO₂ emissions: Reduce the tech sector's carbon footprint by leveraging green servers.
  • Showcase sustainability leadership: Demonstrate your commitment to a greener future to customers and stakeholders.

Why Carbon Matters in CI/CD

Traditional CI/CD workflows often run on servers with high carbon emissions, as they prioritize availability over sustainability. CarbonRunner flips this paradigm by prioritizing regions with renewable energy sources and low grid intensity.
