README

Environmental Impact Tracker

**v1.2.0**

A Claude Code skill that calculates and displays the environmental footprint of your AI interactions, translating abstract token usage into energy consumption (Wh), water usage (mL), and relatable real-world comparisons.

What it does

After heavy turns (5,000+ tokens, subagent use, or complex tasks), Claude automatically displays:

🌍 Environmental Impact of This Response

Energy: 19.36 Wh (about 1 phone charge)
Water:  32.90 mL (about 2 tablespoons)

Model: Claude Sonnet 5
Tokens: 25,000 in + 6,000 out + ~2,500 skill = 33,500
+ 136,000 agent tokens across 4 agents = 169,500 total

💡 If a lighter model had been used:
  Haiku: 6.46 Wh / 10.97 mL  (3.0x less)

Note: Estimates. See references/sources.md for methodology.

Features:

Per-turn impact: energy and water for each heavy exchange
Subagent tracking: includes all spawned agent activity in the total
Skill cost included: accounts for the tokens used to load this skill itself
Model efficiency comparison: shows what the same work would have cost on a lighter model
Cumulative tracking: session, weekly, and project totals via a local log file
Auto-wires enforcement: adds a rule to your CLAUDE.md on first use so it never gets skipped

Installation

Claude Code

/plugin install example-skills@anthropic-agent-skills

Or copy `SKILL.md` (and the `references/` folder) into your Claude Code skills directory:

~/.claude/plugins/cache/anthropic-agent-skills/example-skills/unknown/skills/environmental-impact-tracker/

Manual (any Claude environment)

Paste the contents of `SKILL.md` into your system prompt or project instructions.

Setup

Installing the skill alone is not enough for it to fire automatically. It needs an enforcement rule and a toggle file, both one-time steps:

Add this rule to ~/.claude/CLAUDE.md (global, applies to every project; use a project-local CLAUDE.md instead if you on
