Scope 3 emissions
All other indirect GHG emissions in the value chain, upstream and downstream.
The GHG Protocol defines 15 Scope 3 categories including purchased goods and services, capital goods, fuel/energy-related activities, transportation, waste, business travel, employee commuting, and use/end-of-life of sold products. Scope 3 typically accounts for 70–90% of total corporate footprint, making supply chain engagement critical to net-zero targets.
