Add GreenOps Carbon Scheduler to Carbon Intensity and Accounting

[RamGudivada]

Project Addition

Project: GreenOps Carbon Scheduler

Category: Emissions → Carbon Intensity and Accounting

What It Does

A Python-based GreenOps tool for carbon-aware scheduling of batch data pipelines (e.g., Airflow/Snowflake). It:

• Queries a real-time grid carbon intensity API (gCO2/kWh) before running batch ETL jobs
• Defers jobs to "green windows" (low-carbon periods) with a SLA circuit-breaker
• Estimates the carbon footprint of individual Snowflake queries based on compute tier and duration

Why It Qualifies

• ✅ Open source (MIT license)
• ✅ Actively maintained (initial release Feb 2025)
• ✅ Documented README with usage examples
• ✅ Addresses a gap in the existing list: no tool currently targets carbon-aware scheduling specifically for cloud data warehouses

Related Listing

This tool is closely related to CATS: the Climate-Aware Task Scheduler listed above, but focuses on cloud data warehouse workloads (Snowflake) rather than HPC compute jobs.

Hi @RamGudivada,
The project only contains a few small scripts.
Would you like us to review the project in its current form, or are you still working on it?
