What is the difference between a carbon footprint and a sustainability report?
A carbon footprint is one number — the greenhouse gases associated with your business over a period. A sustainability report is a document that covers environmental, social and governance topics together, explains which of them matter to your business and why, and usually contains a carbon footprint as one part.
They serve different requests. A customer filling in their Scope 3 wants the footprint. An investor, a bank, a large tender or a certification body usually wants the report.
| Carbon footprint | Sustainability report | |
|---|---|---|
| Covers | Greenhouse gas emissions only | Environment, social, governance |
| Method | GHG Protocol | A disclosure framework such as GRI or IFRS S1/S2 |
| Output | A figure, with its boundary and factors | A document, with a content index |
| Typical effort | Hours, from bills you already have | Weeks, and involves several people |
The order matters. Building the footprint first is not a detour — the emissions figures are what GRI 305 and IFRS S2 both want, so the work carries straight into the report.
