Scope 3 Emissions Reporting
Master Your Value Chain Emissions - 70-90% of Your Carbon Footprint
What are Scope 3 Emissions?
Scope 3 emissions are indirect greenhouse gas emissions that occur in your value chain, both upstream and downstream of your operations. According to the GHG Protocol, Scope 3 typically represents 70-90% of a company's total carbon footprint. The CDP reports that addressing Scope 3 is critical for genuine climate action.
Scope 1
Direct emissions from owned sources (5-10% typical)
Scope 2
Indirect emissions from purchased energy (5-20% typical)
Scope 3
All other indirect value chain emissions (70-90% typical)
All 15 Scope 3 Emissions Categories
The GHG Protocol Corporate Value Chain Standard defines 15 distinct Scope 3 categories. Our Scope 3 emissions reporting covers all categories relevant to your business:
Upstream Scope 3 Categories
Purchased Goods & Services
Extraction, production & transportation of purchased products
Capital Goods
Production of capital goods (machinery, buildings, vehicles)
Fuel & Energy-Related
Emissions not included in Scope 1 or 2
Upstream Transportation
Transportation of purchased products & distribution
Waste Generated
Disposal & treatment of waste in operations
Business Travel
Employee transportation for business activities
Employee Commuting
Employee travel between home and work
Upstream Leased Assets
Operation of assets leased by the company
Downstream Scope 3 Categories
Downstream Transportation
Transportation of sold products to end consumer
Processing of Sold Products
Processing of intermediate products by downstream companies
Use of Sold Products
End use of goods and services sold (often largest category)
End-of-Life Treatment
Disposal and treatment of sold products at end of life
Downstream Leased Assets
Operation of assets leased to other entities
Franchises
Operation of franchises
Investments
Financed emissions (critical for financial institutions)

Scope 3 Calculation Methodologies
We use GHG Protocol approved methodologies for accurate Scope 3 emissions calculation:
Primary Data Methods
- Supplier-Specific: Actual emissions data from suppliers
- Hybrid Method: Combination of supplier data and secondary factors
- Average-Data: Industry average emission factors
Secondary Data Methods
- Spend-Based: Economic value × emission factors
- Average-Product: Mass/units × emission factors
- Distance-Based: Distance × mode × emission factors
