Carbon footprint splits into four main types: product (ISO 14067), corporate or organisational (GHG Protocol and ISO 14064-1), national territorial versus consumption-based, and personal. Scope 1, 2 and 3 are not a separate type but the boundary that structures a corporate footprint across direct, purchased-energy and value-chain emissions.
The phrase “carbon footprint” covers several distinct measurements, each with its own boundary and governing standard. Choosing the right one depends on the object being measured: a single product, a whole company, a country, or one person. A product footprint follows life-cycle rules, while a corporate footprint follows GHG accounting frameworks.
Footprint types at a glance
| Type | Boundary / what it measures | Governing standard |
|---|---|---|
| Product carbon footprint (PCF) | GHG of one product across its life cycle, cradle-to-grave or a partial cradle-to-gate scope; climate-change impact only, in CO2e | ISO 14067:2018 (built on LCA, ISO 14040/14044) |
| Corporate / organisational (CCF) | All GHG emissions and removals of a whole organisation over a reporting year | GHG Protocol Corporate Standard (2004); ISO 14064-1:2018 |
| Scope 1 / 2 / 3 | Boundary inside a corporate footprint: direct sources; purchased energy; all other value-chain emissions | GHG Protocol Corporate and Scope 3 (2011) Standards |
| National / territorial | Country total: production-based (emissions inside borders) or consumption-based (including imports) | IPCC methodology, reported to the UNFCCC |
| Personal / individual | One person’s or household’s consumption emissions per year, in tonnes CO2e | No ISO standard; calculators and input-output models |
Which footprint applies
Most corporate reporting under CSRD, BRSR or CDP runs on the corporate footprint, while product-level data feeds EPDs and the EU Digital Product Passport. National and personal footprints, by contrast, are consumption-based estimates with no ISO backing, so their figures vary by method. GreenSutra’s consultants map the right boundary to each obligation through its carbon footprint solutions, and the step-by-step method sits in the carbon footprint guide.
