ISO 14064 vs ISO 14067: Corporate vs Product Carbon Footprint, and Which One Your Buyer Wants

A procurement email lands from a German automotive supplier: "Please send your product carbon footprint per part, ISO 14067, by the end of the quarter." Two weeks later a Scandinavian retailer asks the same exporter for its corporate emissions inventory under ISO 14064. Same company, same year, two different carbon numbers, two different standards. Pay for the wrong study and you will have spent months measuring something your buyer never asked for. The two standards are not interchangeable, and knowing which one a given market wants is now part of staying in the supply chain.

ISO 14064 and ISO 14067 both count greenhouse gas emissions, but they draw the boundary in completely different places. One looks at your organisation. The other looks at a single product. This guide separates them at the level where the decision actually gets made: what each one measures, who is asking for which, and the order to do them in so the work compounds instead of duplicating.

ISO 14064 counts the company, ISO 14067 counts the product

ISO 14064 is an organisation-level standard. It quantifies and reports the greenhouse gas emissions of an entire entity, a factory, a legal company, a site, over a reporting year. It is the corporate carbon footprint, expressed in tonnes of CO2 equivalent for the whole operation. The standard is published in three parts: Part 1 covers the organisational inventory, Part 2 covers project-level reductions, and Part 3 covers the validation and verification of those claims. When a buyer or a sustainability rating asks for your "annual emissions" or your "Scope 1, 2 and 3 inventory", they are pointing at ISO 14064-1.

ISO 14067 is a product-level standard. It quantifies the carbon footprint of one product across its life cycle, from raw material extraction through manufacturing, distribution, use, and end of life. The result is a number attached to a unit: kilograms of CO2 equivalent per part, per litre, per kilogram of finished goods. ISO 14067 is built on life cycle assessment methodology, so it inherits the rigour and the data demands of a full or partial LCA. When a customer wants "the footprint of this specific item", they mean ISO 14067.

The distinction is not academic. A company can have an excellent corporate inventory under ISO 14064 and still be unable to answer a product carbon footprint request, because the corporate number never breaks emissions down to a single SKU. The reverse is also true. The two studies share data sources but produce different deliverables for different questions. You can read how each one is scoped on our ISO 14064 certification page and our ISO 14067 certification page.

Which standard your buyer actually wants

The market signal usually tells you which study to commission, if you read it carefully. Three patterns cover most cases.

Retail and consumer goods buyers increasingly ask for product-level data, because they are building category footprints and on-pack carbon labels. A grocery chain, an electronics retailer, or a fashion buyer that wants "the footprint per item" is asking for ISO 14067. The unit matters to them because they aggregate it across thousands of products.

Investors, banks, and sustainability ratings (CDP, EcoVadis, lenders running ESG screens) want the organisation-level picture. They are assessing the company as a whole, so they ask for the ISO 14064 inventory and, increasingly, third-party verification of it. A tender that scores you on "corporate carbon disclosure" is in ISO 14064 territory.

Regulatory drivers split between the two. The EU Corporate Sustainability Reporting Directive (CSRD) pulls toward organisation-level Scope 1, 2 and 3 reporting, which maps to ISO 14064. The Carbon Border Adjustment Mechanism (CBAM), by contrast, asks for embedded emissions in specific goods (cement, iron and steel, aluminium, fertilisers, hydrogen, electricity), which is a product-level question that draws on ISO 14067 methodology even though CBAM has its own reporting rules. An Environmental Product Declaration (EPD) is also product-level and built on the same LCA backbone as ISO 14067.

If you are unsure which way a request points, look at the unit. "Per year, for the company" is ISO 14064. "Per product, per unit shipped" is ISO 14067. Our team can map an incoming buyer requirement to the right study during a carbon footprint and life cycle assessment scoping call before any measurement begins.

How they feed CBAM, an EPD, and a CSRD filing

The downstream use is what should drive the choice, because each compliance output consumes a different carbon number.

A CBAM filing for steel or aluminium needs embedded emissions per tonne of the specific good crossing the EU border. That is product-level accounting. An ISO 14064 corporate inventory will not satisfy it on its own, because CBAM importers need the emissions tied to the consignment, not to your annual total. The ISO 14067 product study, with its LCA boundary, is the closer fit.

An EPD for a construction product, a tile, an insulation panel, a window, is a product carbon footprint dressed in a standardised report format governed by EN 15804 and product category rules. The carbon module of an EPD is exactly the ISO 14067 question. If your buyers in construction are asking for EPDs, you need product-level life cycle data, not a corporate inventory.

A CSRD or CDP submission wants the full organisational inventory across all three scopes. That is ISO 14064-1, ideally verified under ISO 14064-3 so the disclosure carries third-party assurance. Here the product breakdown is not the deliverable; the consolidated company number is.

The cheapest carbon study is the one you do not have to repeat. Before commissioning either standard, confirm the exact compliance output the number will feed, then scope to that.

Sequencing the two so the work compounds

For most exporters the practical answer is not "one or the other" but "in what order". The corporate inventory and the product footprint share a foundation: activity data, energy bills, fuel records, supplier data, process measurements. Building that data layer once and using it twice is what keeps the cost down.

Start with ISO 14064 when your most pressing demand is corporate disclosure (a CSRD obligation, an EcoVadis scorecard, an investor questionnaire) and you do not yet have a single product under a specific buyer mandate. The organisational inventory forces you to assemble the energy and activity data that any later product study will draw on, and it answers the company-wide questions first.

Start with ISO 14067 when a named customer has put a specific product on the line, a part, a finished good, a material, with a deadline and a contract attached. In that case the product study is the revenue-critical work, and you build the corporate inventory around it afterward, reusing the same emission factors and data sources.

Either way, the sequencing principle holds: collect the underlying data once, structure it so it serves both the organisation-level and the product-level cut, and verify each output to the level its audience requires. Sistem Patent Kalite scopes both standards together at the start, so an exporter facing CBAM on one product line and CSRD at group level does not run two disconnected projects. We map the buyer requirement, set the boundary, and sequence the studies so the second one builds on the first instead of starting over.

The one-line test

When the next carbon request arrives, ask a single question before you commission anything: is the buyer measuring my company, or measuring my product? Company is ISO 14064. Product is ISO 14067. CBAM and EPDs pull product-level; CSRD and ESG ratings pull organisation-level. Get that one distinction right and the rest of the carbon programme, the boundary, the data, the verification, follows from it without a wasted study.
