Scope 3 Emissions: Measuring Your Supply Chain Footprint
S
Statura Team
Scope 3 emissions — those across your value chain rather than your own operations — typically make up the majority of a company's carbon footprint, and are the hardest to measure.
What Counts as Scope 3?
The GHG Protocol defines 15 categories, including purchased goods, transport, business travel, product use, and end-of-life treatment.
Why It Is Hard
- Data sits with suppliers and customers, not you.
- It requires estimation and emission factors.
- Boundaries and double-counting need care.
How to Start
Prioritise the largest categories, use spend- and activity-based estimates, and engage key suppliers for primary data over time.
Statura measures Scope 1, 2, and 3 through its carbon footprint audits and net-zero roadmaps.
