Data Center Operational and Lifecycle Carbon Calculator

Range: 1–100,000,000,000 kWh

Enter annual IT electricity use only, in kWh/year. Apply PUE separately below so facility energy is not counted twice.

Range: 1–5

Enter the facility PUE used for this scenario. PUE 1.0 means no overhead above IT energy; use measured or documented project data when available.

Range: 0–5 kg CO₂e/kWh

Enter the location- and accounting-boundary-specific grid emissions factor in kg CO₂e/kWh. This is a user-selected factor, not a universal U.S. value.

Range: 0–100 years

Enter the operating horizon in years. The model holds annual IT energy, PUE, and the grid factor constant across the horizon.

Range: 0–1,000,000,000,000 kg CO₂e

Enter embodied emissions already defined within the project boundary, in kg CO₂e. Do not add them again for each operating year.
