Track the carbon footprint of your Claude Code sessions, in the terminal and the Claude desktop app

Why this job: topics: claude-plugin, claude-code-plugin, claude-code

Open on GitHub Website

claude-carbon, free and open source: the CO2 of your Claude Code sessions, in the terminal and in the Claude app. Eight pixel molecules from dark blue to dark red, a terminal whose status line reads 8.2gCO2, and the /carbon-panel pane: this session

claude-carbon in 16 seconds: Claude Code never shows its CO2; claude-carbon puts it in the terminal status line, then in the Claude desktop app, where /carbon-panel opens a pane with a pixel molecule coloured by this session

Illustration of the Claude desktop app with the claude-carbon pane open: a blue pixel molecule, "This session: 8.2 gCO₂ · 0.04× your median", the last 30 days as tiles and warming stripes, a "Get my 2026 card" button, and "This session: 8.2 gCO₂" under the prompt
