How to Calculate Scope 3 Emissions
Scope 3 covers all indirect emissions in your value chain not included in Scope 2. These are typically the largest portion of a company's total footprint.
15 Categories of Scope 3
Upstream: purchased goods/services, capital goods, fuel/energy activities, transportation, waste, business travel, employee commuting, leased assets.
Downstream: product transportation, processing, use of sold products, end-of-life treatment, leased assets, franchises, investments.
Formula
Total Scope 3 = Sum of all category emissions
Example Calculation
A mid-size company with estimated Scope 3 across four main categories.
- 01Purchased goods: 200 metric tons CO2e
- 02Business travel: 50 metric tons CO2e
- 03Employee commuting: 80 metric tons CO2e
- 04Waste disposal: 20 metric tons CO2e
- 05Total Scope 3: 200 + 50 + 80 + 20 = 350 metric tons CO2e
