The carbon footprint of Mistral Vibe Pro
Mistral AI publishes some per-prompt figures: a life-cycle analysis with Carbone 4 and ADEME: emissions, water and materials per response, but no energy figure. Below is what a Mistral Vibe Pro subscription plausibly emits in a month, with every assumption shown, and a pass that funds well beyond it.

Funds about 110 kg of verified carbon credits a month — roughly 7.6× the high end of this estimate.
The assumptions
- Pro
- 10 to 100 queries a day, with up to 25% long reasoning answers at the high end.
- Per query
- One 400-token response from Mistral Large 2 in Le Chat (since renamed Mistral Vibe), from a life-cycle analysis carried out with Carbone 4 and the French ecological transition agency ADEME. A life-cycle figure counts far more than electricity — including making the hardware — so it runs higher and is not directly comparable to the energy-only figures above.
- Left out
- Image and video generation, and the large contexts coding agents read on every step — no published study measures those yet.

Common questions
- How much CO₂ does Mistral Vibe Pro produce?
- By our estimate, 350 g – 15 kg CO₂e a month — from light use to hard daily use with long reasoning answers. Nobody outside Mistral AI knows actual usage, so this is a range, not a measurement.
- Does Mistral AI publish the environmental impact of Mistral Vibe Pro?
- Mistral AI publishes some per-prompt figures: a life-cycle analysis with Carbone 4 and ADEME: emissions, water and materials per response, but no energy figure.
- What does the climate pass for Mistral Vibe Pro fund?
- The Everyday pass costs $3 a month and funds about 110 kg of verified carbon credits at today's price — roughly 7.6× the high end of our estimate. The credits are retired in your name with registry serial numbers.
- Does the pass make Mistral Vibe Pro carbon neutral?
- No. It funds verified carbon credits, which you can check on a public registry. The emissions from your AI use still happened — the honest claim is how many kilograms of credits you funded.
