TokenClimate

TokenClimate is a French service that measures what an organisation's AI usage costs and emits, team by team. It grew out of an open source command line tool its founder published in April 2026 to track the carbon footprint and spend of his own Claude Code sessions, and applies the same approach across a company. A dashboard breaks down Anthropic and OpenAI spend by team, person, model and session, and shows estimated CO2e emissions and litres of water alongside cost. It is aimed at organisations already spending at least €2,000 per month on AI. Claude Code, the Claude API and the OpenAI API connect immediately, and Codex is counted when it runs on an OpenAI API key; other tools are connected only after checking that usage data is accessible. Chat products such as claude.ai and ChatGPT are not measured. An initial assessment takes about a week for Claude Code and Codex, followed by a monthly review that prices reduction options such as switching suitable tasks to a smaller model. The service reads usage volumes only, never conversations, groups figures by team unless named reporting is chosen, hosts data in Europe and supports export. The carbon methodology is public, and carbon figures are estimates because model providers do not publish energy data. Pricing is not published. It depends on the tools connected and the level of AI spend, and a written quote follows a free 30 minute call. The site is in French, and the founder states capacity for three pilot clients by the end of the year.
