CarbonInk is free, open-source (MIT) carbon accounting for macOS & Windows. It runs fully offline — your data stays in SQLite on your machine. AI extracts activity data from bills, receipts and freight docs (BYO LLM key: OpenAI, Anthropic, Gemini, DeepSeek), every number traces back to its source and a pinned emission factor, and one click exports an ISO 14064-1 GHG inventory report. It fills customer questionnaires and collects Scope 3 supplier data. Built-in MCP server for Claude & Cursor.
