Key figures, per million tokens
| Energy | CO₂e | Water | Price | |
|---|---|---|---|---|
| Input tokens | 7.4 kWh | 3.2 kg | 33.9 L | €2 |
| Generated tokens | 44.6 kWh | 19 kg | 203 L | €9 |
Gemini 4 Argon emits 2,642% more than the median of the 34 models in the TokenClimate registry (691 g per million generated tokens), that is ×815 compared with Mistral Small 4, the most frugal.
One million generated tokens represents about 133 km in a combustion car and 3 showers.
Frequently asked questions
How much CO₂e for 1 million tokens with Gemini 4 Argon?
About 19 kg per million generated tokens and 3.2 kg per million input tokens (factors tokenclimate-v4-2026-10 of the TokenClimate registry).
Where do these figures come from?
Factors published in TokenClimate's versioned registry, each with its citation on this page. The full equations and parameters are in the public methodology, at tokenclimate.com/en/methodology.
What is the confidence level?
Low confidence: extrapolated from another model, or estimated by a parametric tool.
How can you measure your organisation's real usage?
The TokenClimate dashboard connects to your organisation's Anthropic, OpenAI or OpenRouter admin keys (stored encrypted) and measures cost and CO₂e per team and per model. You can see it in the demo: tokenclimate.com/demo. Locally, the open source plugin claude-carbon measures a Claude Code session.
