Carbon Footprint Analysis
The total amount of greenhouse gas emissions, typically measured in carbon dioxide equivalents, produced directly and indirectly by an activity, product, or organisation.
Formula
Carbon Footprint (CO₂e) = Activity Data × Emission Factor
Real World
Apple reported a total corporate carbon footprint of 20.6 million metric tonnes CO₂e in 2022, with over 70% attributed to Scope 3 supply chain manufacturing emissions.
Exam Focus
Specify Scope 1, 2, and 3 categories in extended answers — omitting supply chain (Scope 3) is a common error that loses marks.
