Product Carbon Footprint (PCF): definition, method and challenges for companies

‍

More and more companies are being asked by their customers, investors or contractors for the carbon footprint of their products and no longer just that of the company as a whole.

‍

This is called the Product Carbon Footprint, the PCF, or the carbon footprint produced. The PCF measures the greenhouse gas emissions generated by a product over its entire life cycle.

‍

Long reserved for large industrial companies, the PCF is now becoming a strategic tool for a growing number of organizations. The pressure is both regulatory (CSRD, MACF...) and commercial, with buyers who now include the PCF in their supplier selection criteria.

‍

In this article, we explain to you what the PCF is in practice, how to calculate it, how it differs from the carbon footprint and why it has become a must for any company wishing to seriously pilot its decarbonization strategy.

‍‍

1. What is the Product Carbon Footprint?

‍

The Product Carbon Footprint (PCF) is a method for measuring greenhouse gas (GHG) emissions generated by a product or service over its entire life cycle: from the extraction of raw materials to its end of life, including its manufacture or use.

The results are expressed in kilograms of CO₂ equivalent (kg CO₂ e), which makes it possible to have a clear and quantified vision of the climate impact of a product and to identify the most emitting steps to guide reduction efforts.

‍

• The reference standard: ISO 14067

‍

ISO 14067:2018 is the international standard that specifies the requirements and guidelines for calculating and presenting a Product Carbon Footprint.

‍

It allows companies to follow a clear, rigorous and uniform methodology for carrying out their PCFs and thus ensure their compliance.

‍

• What are the differences between a PCF and a full LCA?

‍

The PCF is different from a Life cycle analysis (LCA) complete by its deliberately restricted scope: it is only interested in the “climate change” indicator by measuring only the emissions of greenhouse gases linked to the product.
‍

Where a multi-criteria LCA also analyzes the impact on biodiversity, water eutrophication, resource depletion or even terrestrial and freshwater acidification.
‍

The PCF thus makes it possible to focus on the carbon footprint and thus to very clearly identify the stages of the product life cycle that emit the most. It is a major tool for companies that want to focus their decarbonization efforts where the levers are most important and thus give themselves every chance of massively and more quickly reducing their emissions.

‍

• What are the differences between a PCF and a carbon footprint?

‍

The PCF and the carbon balance share the fact of measuring greenhouse gas emissions in both cases.
‍

On the other hand, the carbon footprint analyzes the GHG emissions of the company and its value chain and not of a product or service. We take into account all the inputs, the impact of all the products manufactured by the company but also the travel of employees or the energy used to heat the premises.
‍

Whereas the PCF focuses only on the data of the product (s) studied.
‍

The PCF allows you to zoom in on the precise impact of a system studied where the carbon balance makes it possible to have a global vision of emissions related to the company's activity.
‍

But PCF and carbon balance are not opposed, they are even complementary. We'll see that a bit later in this article.

‍

2. Why do a Product Carbon Footprint?

‍

• Meet the requirements of your partners and contractors

‍

Today, large companies are no longer content with greening their own perimeter (Scope 1 and 2). To achieve their neutrality goals, they are tackling their Scope 3: the emissions in their value chain.

‍

As a result, major accounts are becoming more and more demanding and require their suppliers to provide accurate and verifiable carbon data.

‍

Mastering your PCF means guaranteeing your place in these supply chains and transforming a compliance constraint into a major commercial advantage.

‍

• Anticipating regulatory and financial pressure

‍

The European legislative framework is getting tougher. The PCF is becoming an essential tool to meet two major regulations:

‍

• The CSRD (Corporate Sustainability Reporting Directive): it requires large companies to report their environmental impacts in detail.

‍

• The MACF (Carbon Border Adjustment Mechanism): for the sectors concerned, calculating the carbon content of products is now an obligation to cross European borders.

‍

At the same time, investors are increasingly integrating ESG criteria into their decisions. A robust PCF is a guarantee of transparency that reassures the company's ability to manage its long-term climate risks.

‍

• Refine and manage your decarbonization strategy

‍

The PCF is the essential complement to the company's carbon footprint. Where the Carbon Balance offers a macroscopic vision, the PCF allows:

‍

• to identify the “Hotspots”: it makes it possible to isolate the most emitting stages of the life cycle.
• to be more precise: by injecting real product data into your global carbon footprint, you gain in precision and get rid of monetary ratios that are often too inaccurate
• to prioritize: you are no longer working blindly, you are focusing your reduction efforts where the impact is greatest.

‍

• Engaging a genuine eco-design approach

‍

As ADEME points out, ecodesign aims to reduce the impacts of a product as soon as it is created. The PCF (often based on the PEF - Product Environmental Footprint methodology) is the first brick in this approach. It allows you to:

‍

• Compare scenarios: test the impact of an alternative material or a change of supplier before production.
• Benchmarking: comparing your products internally or against the competition to aim for environmental excellence.

‍

• Communicate transparently and avoid greenwashing

‍

At the time of environmental labelling (already effective in textiles since October 2025 and soon extended to food, furniture or cosmetics), transparency is an obligation of reputation.

‍

Relying on a PCF that complies with standards makes it possible to make robust environmental claims. This is the only way to prove the performance of your products to consumers and avoid accusations of greenwashing, while valuing your reduction efforts in a factual way.

‍

3. How do you calculate a Product Carbon Footprint (PCF)?

‍

As with a CVA, there are 4 main steps to follow.

‍

Definition of the objectives and the field of study

‍

• Objective of the study

‍

This is the reason why the company decides to carry out a LCA: eco-design, comparison of several products or services, comparison with the competition...

‍

• The field of study

‍

This is when the main characteristics and hypotheses that are chosen are specified.

‍

• Do we carry out a cradle-to-grave PCF, “from cradle to grave”, therefore over all stages of the product's life cycle, or a cradle-to-gate PCF, “from cradle to door” which excludes the stages of use of the product and its end of life? If it's a cradle-to-gate PCF, the company should explicitly mention it in their inventory report.

‍

• What is the functional unit of the product or service covered by the Product Carbon Footprint? This is fundamental in defining the field of study. The functional unit is the primary function, the service provided by the system under study.

‍

Some examples of functional units: number of times a garment is worn, travel 15,000 km/year and for 20 years for a car, etc...

‍

• Methodological limitations.

‍

Life cycle inventory

‍

This is the most time-consuming step, the one that corresponds to data collection. The aim is to trace all the flows of the product studied: the incoming and outgoing flows.

‍

It is necessary to collect all the data that is directly attributable to the life cycle of the product based on the definition of the field of the study and on the flow map that will be developed.

During this stage, businesses must pay attention to the quality of the data collected. Several types of data are available: primary data, secondary data, financial data.

Companies must be able to assess the quality of the data in order to select those that are most representative of the product's real emissions, based on precise indicators (temporal, geographical, etc.).

Evaluating the quality of the data then allows:

• improve the quality of current and future inventories by identifying the lowest quality data. The company can thus identify which data it should focus its efforts on to improve its quality.
• document the inventory process and thus provide information if an audit phase is carried out.
• provide proof to its stakeholders of the quality of the data used during the inventory

‍

Impact assessment

‍

For the results of a PCF, the unit used is the equivalent CO2 (CO2e).

‍

It is then a question of passing on the data collected in CO2 equivalent. Businesses must apply a global warming potential (GWP) factor to 100 years.

‍

Thus, for all the greenhouse gases that will appear in the life cycle inventory, they will have to be converted into CO2e by associating them with a characterization factor. For methane, for example, we know that 1 ton of methane is equivalent to 28 tons of CO2. We will therefore multiply the methane fluxes by this factor of 28. As another example, for nitrous oxide, its global warming potential is 298 times higher than CO2. A factor of 298 is therefore associated with it.

‍

Interpreting results and reporting

‍

That's when we move from accounting to action.

‍

This phase is used to verify the robustness of the study, in particular:

‍

• by identifying which stages of the life cycle (raw materials, transport, manufacturing, end of life) contribute the most to the total footprint.
• by conducting an uncertainty analysis: the margin of error related to the databases used must be explained

‍

If you decide to report on the results of the Product Carbon Footprint, the report should include:

• The Scope: “Cradle-to-Grave” (cradle-to-grave) or “Cradle-to-Gate” (cradle-to-gate).
• exclusions: what was not included in the carbon footprint produced?
• Methodological choices

‍

This last step is crucial in order to both communicate transparently about your approach and to identify what could be called opportunities to reduce greenhouse gas emissions, i.e. the most important reduction levers.

FAQS

‍

1. Does the PCF replace my company's carbon footprint?

No, they are complementary. The Carbon Footprint gives a global vision of the climate health of your organization (offices, trips, vehicle fleet, etc.), while the PCF is a magnifying glass placed on a specific product. Carrying out a PCF allows you to refine your overall Carbon Balance by replacing monetary estimates with real and accurate data related to your manufacturing cycle.

‍

2. What is the difference between a “Cradle-to-Gate” and a “Cradle-to-Grave” calculation?

It all depends on the use of the report:

• Cradle-to-Gate (from cradle to door): stops the moment the product leaves your factory.
• Cradle-to-Grave (from cradle to grave): includes use by the end consumer and waste treatment.

‍

3. Is it mandatory to follow the ISO 14067 standard?

Although not a strict legal requirement for all businesses, following the ISO 14067 standard is recommended. It guarantees your investors and customers that your results are comparable, transparent and based on a scientific methodology recognized worldwide.

‍

4. Why give priority to the PCF rather than a complete LCA?

The PCF is faster and cheaper to implement because it focuses on a single indicator: climate change. It is the ideal tool if decarbonization is your strategic priority. However, if you want to communicate on other environmental aspects (water consumption, ocean protection, etc.), you will then have to move towards a multi-criteria Life Cycle Assessment (LCA).
