Carbon Aware SDK
A toolkit for building carbon-aware applications.
Overview
The Carbon Aware SDK is an open-source project from the Green Software Foundation. It's a WebAPI and command-line tool that allows developers to fetch and use grid carbon intensity data from various providers. This enables the creation of 'carbon-aware' applications that can intelligently shift workloads to times or regions where the electricity grid is powered by more renewable sources, thus reducing emissions.
✨ Key Features
- Provides a standardized WebAPI to query carbon intensity data
- Supports multiple data sources (e.g., WattTime, Electricity Maps)
- Calculates the best time window or location to run a workload for lowest emissions
- Command Line Interface (CLI) for easy scripting and integration
- Enables 'load shifting' and 'location shifting' of compute workloads
🎯 Key Differentiators
- Open-source and vendor-neutral
- Standardizes access to multiple carbon intensity data providers
- Focuses on actionable reduction, not just measurement
Unique Value: Provides developers with the tools to actively reduce software emissions by aligning compute workloads with the availability of renewable energy on the grid.
🎯 Use Cases (4)
✅ Best For
- Integrating into Kubernetes schedulers to make pod placement carbon-aware
- Delaying non-critical batch processing until the grid is cleaner
💡 Check With Vendor
Verify these considerations match your specific requirements:
- Latency-sensitive applications that cannot be time-shifted
- Carbon footprint measurement and reporting (it's for reduction)
🏆 Alternatives
As an open-source standard, it prevents vendor lock-in and promotes a common, community-driven approach to building carbon-aware software.
