What it does
An open source Claude Code plugin that estimates the CO2 footprint of a coding session from token usage and shows it live in the status line next to the session cost. It keeps history in a local SQLite database so it survives the transcript purge, and includes commands for reports and for checking a pull request's footprint.
Use cases
- 01Show a live CO2 estimate during a coding session
- 02Generate a carbon report for a period of time
- 03Check the footprint of a specific pull request
