Claude Code CO₂ leaderboard — who's burning the most rainforest with AI?
Self-reported · Not verified · For laughs and existential dreadEvery prompt to Claude burns electrons in a data centre, which (depending on grid mix) burns kerosene, coal, or — increasingly — wind. This leaderboard turns the joke into a number. Self-reported via the Claude Usage Tracker: download, run locally, hit "Burn dem Trees".
What you're seeing: aggregated GPU-hour and CO₂ totals per submitter, computed server-side from H100 TDP (700 W) × grid average (0.4 kg CO₂/kWh) × tree absorption (22 kg CO₂/year/tree). Numbers are estimates. The leaderboard ranks by submitted CO₂ — climb at your own existential cost.

Server: Hetzner, Germany. Lawful basis: GDPR Art. 6(1)(a) consent. We store: pseudonym (if provided), aggregated GPU/CO₂ stats, daily/weekly/monthly/yearly buckets, optionally hourly buckets for last 24h (only if user ticks consent), salted SHA-256 hash of IP (for rate-limiting; IP itself never stored).
We never store: prompts, project paths, file paths, model names, sessions, conversation logs, raw token streams, plain IPs, or device fingerprints.
You can erase your entry any time via the "Remove me" button in the local tracker (uses the deletion token returned at submission). Auto-prune kicks in once 10 000 rows are reached. Pseudonyms are first-come-first-served and bound to your IP-hash; impersonation attempts get rejected.
