Scope 3 Supply Chain Emissions Estimate Calculator

Estimate Scope 3 value chain emissions using spend-based, average-data, and supplier-specific methods across all 15 GHG Protocol 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 value chain emissions using spend-based, average-data, and supplier-specific methods across all 15 GHG Protocol categories

Each component has a specific meaning:

  • Spend-based — The spend-based recorded for the scenario being assessed.
  • Average-data — The average-data recorded for the scenario being assessed.
  • Supplier-specific methods across all 15 GHG Protocol categories — The supplier-specific methods across all 15 ghg protocol categories recorded for the scenario being assessed.

Note: Interpret the scope 3 estimate result against the thresholds and context described above.

How to Use

Enter the spend-based, average-data, supplier-specific methods across all 15 GHG Protocol categories for the scenario you are assessing. Estimate Scope 3 value chain emissions using spend-based, average-data, and supplier-specific methods across all 15 GHG Protocol categories. Use the scope 3 estimate result to inform your calculation.
