Carbon Footprint vs Life Cycle Assessment
A carbon footprint measures an organisation; an LCA measures a product. They use overlapping data but answer different questions.
A corporate carbon footprint quantifies the total GHG emissions of an organisation over a period. An LCA quantifies the environmental impacts of a specific product across its full life cycle.
Side by side
| Dimension | Corporate Carbon Footprint | Life Cycle Assessment (LCA) |
|---|---|---|
| Unit of analysis | The organisation / reporting entity | A product or service |
| Standard | GHG Protocol Corporate Standard, ISO 14064-1 | ISO 14040/14044, GHG Protocol Product Standard, PEF |
| Scope | Scope 1 + 2 + 3 over a reporting year | Raw materials → end of life |
| Impacts | GHG only (CO₂e) | GHG + water, land use, toxicity, biodiversity, resource use |
| Use case | Disclosure, target-setting, financed emissions | Product design, EPDs, eco-labels |
You need to disclose, set targets or fund transition at organisation level.
You need to design a lower-impact product, respond to customer LCA requests or issue an EPD.
Frequently asked questions
Can product LCAs feed a corporate footprint?+
Yes — product LCA results are a rich source of primary data for Scope 3 category 1 (purchased goods) and 11 (use of sold products).
Both are sustainable-finance instruments, but they work differently: a Green Loan finances a specific green project; an SLL is general-purpose credit whose pricing moves with sustainability performance.
The CSRD is the EU directive; the ESRS are the technical standards it mandates. One creates the reporting obligation, the other tells you how to report.
Scope 1 and 2 are the emissions a company controls directly or via purchased energy. Scope 3 is everything else in the value chain — typically 70–90% of the total.
