Upstream Emissions

Meaning statusEstablishedSource recordDirect source requestedWhy these are different

Definition

Upstream emissions are the greenhouse gas emissions occurring in an organisation's value chain before its own operations: extraction, production and transport of purchased goods and services, capital goods, fuel- and energy-related activities, business travel, employee commuting and upstream leased assets (Scope 3 categories 1–8). For most companies in most sectors, upstream categories — above all purchased goods and services — dominate the total footprint, often by an order of magnitude over direct emissions.
