CarbonRunner

CarbonRunner is designed to make continuous integration and deployment workflows more sustainable by automatically running GitHub Actions jobs in regions with the lowest carbon intensity. By dynamically selecting from over 47 low CO2 regions across multiple cloud providers, it achieves a 90% reduction in carbon emissions compared to traditional GitHub runners. This is accomplished with a simple one-line change in the workflow configuration, making it easy for developers to adopt greener practices without sacrificing performance or flexibility. CarbonRunner also tracks and reports carbon savings, providing measurable environmental impact for users.

CarbonRunner shifts AI training and CI/CD workloads to data centers in the lowest-carbon regions across multiple clouds, reducing CO2 emissions by up to 90% and saving costs by up to 25%. It uses live grid data to optimize workload placement in real-time.
