Why Supplier Engagement is Paramount for Scope 3

While Scope 1 (own facilities, vehicles, heat, operations, etc.) and 2 emissions (purchased energy) are generated and controlled a company’s own operations, Scope 3 emissions encompass all indirect emissions generated by a company’s activities along the supply chains.

The 15 Categories of Scope 3 Emissions along the Supply Chain

According to the Greenhouse Gas Protocol (GHG Protocol), the indirect Scope 3 emissions include 15 different categories, ranging from the procurement of product and services (Scope 3.1) and transportation (Scope 3.4) upstream, to End-of-Life (Scope 3.12) and investments (scope 3.15) downstream.

Scope 1, 2, 3 emissions

Upstream Emissions

3. 1. Purchased Goods and Services – emissions generated by the raw material extraction and processing of goods and services used by a company for its own activities.

3.2. Capital Goods – emissions resulting from the production of plant, equipment, machinery and other long-term capital goods that a company uses in its operations.

3.3. Energy and Fuel-Related Activities – emissions that arise from upstream and network losses of energy and fuel.

3.4. Upstream Transportation and Distribution – emissions generated by the transportation and distribution of raw materials and products delivered to the company by suppliers.

3.5. Waste – emissions from the disposal and treatment of waste.

3.6. Business Travel – emissions that arise from business trips by a company’s employees.

3.7. Employee Commuting – emissions that arise from the daily commute of a company’s employees.

3.8. Upstream Leased Assets – emissions from buildings or vehicles rented from third parties.

Downstream Emissions

3.9. Downstream Transportation and Distribution – emissions that arise from transportation and distribution to customers or end users – or paid for by third parties.

3.10. Processing of Sold Products – emissions from processing products sold.

3.11. Use of Sold Products – emissions generated during the usage of a product by customers or end users.

3.12. End-of-Life Treatment of Sold Products – emissions generated during the disposal and treatment of products after they have reached the end of their life.

3.13. Downstream Leased Assets – emissions resulting from the use of fixed assets rented or leased by a company to other companies.

3.14. Franchises – emissions generated by franchisees’ business activities.

3.15. Investments – emissions that arise from a company’s investments in other companies or projects.


As indirect upstream Scope 3 emissions are typically 11.4x bigger than the direct Scope 1 and 2 emissions of a company, effectively managing and reducing them is paramount to meet corporate climate goals.

Rising Regulatory Landscape requires transparent Scope 3 Data

Overview of sustainability standards and regulation worldwide.


As Scope 3 emissions are generated, managed and controlled directly or indirectly by suppliers and business partners, supplier engagement is a crucial part of holistic climate management to address the Scope 3 challenge. The importance of doing so, is driven by rising international regulation.
