1 pair of jeans (making) = 125,000 AI prompts
1 pair of jeans (making) equals roughly 125,000 AI prompts on the CO₂ side: 25,000 g, while an average text prompt weighs just 0.2 g. The math, the source and detailed equivalents are right below, with public, verifiable numbers.
Figures updated on June 30, 2026 · Source : ADEME : Base Empreinte / Impact CO2
The CO₂ of a prompt reflects the emissions of the electricity used while answering, on an average power grid. On the action side, figures include production (food, goods) or combustion (transport). Here again, we compare orders of magnitude, not gram-perfect measurements.
Why 125,000 prompts?
The math fits in three lines, using public, sourced values:
- 1.1 pair of jeans (making): 25,000 g (ADEME : Base Empreinte / Impact CO2)
- 2.1 text prompt: 0.2 g (published range: 0.15 to 1 g)
- 3.25,000 g ÷ 0.2 g ≈ 125,000 prompts
In other words, “1 pair of jeans (making)” weighs as much as 125,000 questions asked to a generative AI. It is an order of magnitude, not a to-the-decimal measurement: sources publish ranges, and we use a median value, explained in our methodology.
What about a generated image or a reasoning prompt?
Not every AI use weighs the same. A generated image costs about 6 g and a “reasoning” prompt about 13.3 g, versus 0.2 g for a simple text prompt. So “1 pair of jeans (making)” is also roughly 4,167 times one generated image, or 1,880 times one reasoning prompt.
Convert your own usageWhere do these numbers come from?
The value we use for “1 pair of jeans (making)” comes from “ADEME : Base Empreinte / Impact CO2”, referenced like all our data on the Sources page. No number on this page is made up: every value can be traced back to a public document.
On the prompt side, there is no official meter: we convert the electricity used with the average grid intensity (about 480 g of CO₂ per kWh), which lands around 0.15 g in operation. We use 0.2 g per prompt, rising towards 1 g over the full life cycle.
