Create a clip of 10 seconds

A 10-second video in 720p in a single piece, with an open generator. Projet Celsius estimate.

"Second of video" accounts for 91% of emissions in this scenario.
100% of the calculation rests on database assumptions; it does not measure actual use.
Out of scope: server manufacturing, model training and the user's device.

Reading: a single use of "10-second clip" weighs as much as 18 phone charges. Carbon footprint (CO2e) over one year, by number of uses. Each use is a straight line; "10-second clip" is highlighted, with the chosen parameters, compared with 6 reference uses at their default settings; the solid line shows one phone charge per week over a year, and the point where the task reaches it. Servers worldwide. Calculation from the AI Impact Database by Projet Celsius.

How the calculation is built

The computation for a video grows as the square of its duration: 10 seconds cost about 3.4 times the 5.4-second video measured.

Comparison with the other uses

Published readings, conventions, assumptions

What this figure rests on

Projet Celsius assumptions 100 %

A share counts as an assumption as soon as a quantity set by Projet Celsius (a frequency, a share done with AI, a headcount) enters its calculation, even if the rest rests on published measurements.

Methodology conventions

With their alternatives

The full methodology

The data centre	Server electricity is multiplied by 1.10 for the data centre · alternatives: × 1.72 from chips to the full service at Google, never to be combined
The default location	Without other information, the servers are in the world, at the world average electricity · alternatives: the United States, where most of the large assistants run
Electricity, location-based, on a life cycle basis	The kilowatt-hour is that of the servers' country, on a life cycle basis, from a single source for all countries · alternatives: market-based, with purchase contracts, shown alongside when published
Two significant figures	A calculated value is rounded to two significant figures, a published value is reproduced with the precision of its source; the calculation keeps full precision
The formula	the sum of what makes up the entry, then CO2e: electricity (Wh) multiplied by the carbon intensity of the server location (gCO2e/kWh), divided by 1,000
Calculate a case without an entry	The formula, the default values and a step-by-step example
