SCI Calculator

The Sustainable Compute Intensity (SCI) score measures the carbon impact of running a workload. It combines the energy used, the carbon intensity of the region, and the model’s resource footprint.

SCI Formula

SCI = (E × I) + MR

Where:

• E = Energy consumed by the workload (kWh)
• I = Carbon intensity of the region (gCO₂/kWh)
• MR = Model resource overhead (gCO₂)

Example

If your workload uses 10 kWh in a region with 200 gCO₂/kWh carbon intensity, and your model overhead is 50 gCO₂:

SCI = (10 × 200) + 50 = 2050 gCO₂
