CarbonInk is a free, open-source desktop tool for greenhouse-gas accounting on macOS and Windows. It runs offline, and its README says user data does not leave the device. The inventory tracks emission sources, activity data, and pinned emission factors across Scope 1, 2, and 3. AI can extract activity data from utility bills, fuel receipts, freight, travel, and purchase documents when users provide their own LLM API key. Users can fill customer or rating-agency disclosure forms from the inventory and collect supplier data for Scope 3 Category 1. The app produces an ISO 14064-1 inventory report as a PDF in one click. Pinned factors and calculation snapshots form an audit trail. A built-in MCP server exposes inventory data to Claude, Cursor, and Pi. CarbonInk is licensed under MIT. Its Free plan costs nothing, with no account, cloud service, or subscription. The README directs users to the releases page for macOS and Windows builds and says no activation key is needed.
