Supply Chain Carbon Per Dollar Spend Calculator

Estimate Scope 3 Category 1 emissions using USEEIO spend-based emission factors. Calculate kg CO2e per dollar spent across product categories.

2D stress state at a point. All stresses in MPa.

σx — Normal Stress X (MPa)
σy — Normal Stress Y (MPa)
τxy — Shear Stress (MPa)
⚙ Mechanical Note: Results are based on standard textbook formulas and ISO/AASHTO references. Always verify critical designs with applicable codes (ISO 898, AASHTO 1993, AISC, Eurocode 3) and a qualified engineer.

How It Works

Estimate Scope 3 Category 1 emissions using USEEIO spend-based emission factors. Calculate kg CO2e per dollar spent across product categories

Each component has a specific meaning:

  • USEEIO spend-based emission factors — The useeio spend-based emission factors recorded for the scenario being assessed.

Note: Interpret the supply chain carbon/$ result against the thresholds and context described above.

How to Use

Enter the USEEIO spend-based emission factors for the scenario you are assessing. Estimate Scope 3 Category 1 emissions using USEEIO spend-based emission factors. Calculate kg CO2e per dollar spent across product categories. Use the supply chain carbon/$ result to inform your calculation.
