From food to furniture, companies across the world are under mounting pressure to show the real impact of the products they sell. And the smartest brands are already ahead of the curve.
Brands like Caudalie, Swisscom and Wickes are embracing carbon footprinting to gain visibility across complex supply chains, make more informed decisions, and meet the rising bar of sustainability disclosure.
In this guide, you’ll learn what a product carbon footprint really is, why it’s essential for today’s businesses, and how to get started with confidence. Whether you’re reporting to investors, preparing for CSRD, or future-proofing your portfolio, PCFs are your foundation for action.

A product carbon footprint (PCF) measures the total greenhouse gas (GHG) emissions linked to a product throughout its life. From raw material extraction to manufacturing, transport, use, and disposal, every stage is accounted for in carbon dioxide equivalent (CO₂e).
Unlike a corporate carbon footprint, which captures company-wide emissions, a PCF focuses on a specific product or product line—whether it’s a pair of shoes, a bottle of shampoo, or a building material. It’s a precise way for businesses to understand the climate cost of what they make and sell.
PCFs help trace emissions through the value chain and are increasingly used to support carbon labelling, offering customers transparency and helping companies meet stakeholder and regulatory demands
PCFs are powerful tools that:
(Imagine a spider diagram here with “Product carbon footprint” in the centre and the three bullet points surrounding it.)
Net-zero targets are only as strong as the data behind them. PCFs provide reliable, detailed emissions data that allow companies to confidently report on carbon-neutral products or supply chain impacts. They’re increasingly essential for meeting disclosure rules and avoiding greenwashing risks.
PCFs break down emissions by lifecycle stage, spotlighting the highest-impact areas for intervention. For example, knowing whether more emissions come from raw materials or manufacturing lets businesses act with precision.
More buyers and lenders now expect emissions data at the product level. PCFs help demonstrate climate performance, support supplier comparisons, and improve access to green finance and preferred partnerships.
A product carbon footprint is a focused type of life cycle assessment (LCA) that deals only with GHG emissions.
| Aspect | PCF | LCA |
| Focus | GHG emissions only | Broader environmental impacts |
| Metric | CO₂e | Water, land use, toxicity, etc. |
| Complexity | Simpler, quicker | More comprehensive and detailed |
| Use case | Carbon labelling, net-zero plans | Policy-making, full environmental profiling |
Calculating a product carbon footprint involves a series of clear, structured steps. From defining boundaries to collecting lifecycle data and applying emissions factors, each stage plays a vital role in producing accurate, credible results. Here’s how the process works.
Before starting, clarify why you’re calculating a product carbon footprint. This will shape your data collection process and determine how you use the results. Common goals include:
The clearer your questions, the more focused and useful your PCF will be.
You’ll need to determine how much of the product’s lifecycle your carbon footprint will cover.
| Boundary Type | What’s Included | Best For |
| Cradle to gate | Emissions from raw materials through to manufacturing and transport to the factory gate | B2B products, where downstream use is outside your control |
| Cradle to grave | All cradle-to-gate stages plus product use, disposal, and end-of-life treatment | Consumer goods, or when you influence or control the product’s entire lifecycle |
A cradle-to-gate analysis may be sufficient if you’re a supplier selling to other manufacturers. But if you’re making consumer-facing products, a cradle-to-grave boundary provides a fuller picture of environmental impact—especially where usage or disposal emissions are significant.
Be sure to clearly document which boundary you’ve selected, as it affects comparability with other PCFs.
Data collection is the most time-consuming stage—but also the most critical. You’ll need to gather inputs for each step of the product lifecycle. These should include:
Primary data (e.g. kWh of electricity used, km transported) is the most accurate and should be used wherever possible. When unavailable, secondary data (from emissions databases or industry averages) can be substituted but must be flagged in your final results.
Once you have your activity data, emissions are calculated using the following formula:
Activity data × Emissions factor = GHG emissions (CO₂e)
Emissions factors vary by country, energy source, transport method, and material type. They are published by trusted sources such as:
Make sure to use the most recent and geographically relevant factors available.
CO₂e (carbon dioxide equivalent) is the standard unit for expressing the impact of all greenhouse gases—like methane and nitrous oxide—based on their global warming potential (GWP). This allows all GHGs to be reported using a single comparable metric.
Example:
1 kg of methane = 25 kg CO₂e (using a GWP of 25)
If your process produces more than one product or output (e.g. cheese and whey, petrol and diesel), you must fairly distribute emissions among them. The GHG Protocol offers several acceptable methods:
| Allocation Method | How it Works | Best Used When… |
| Mass-based | Emissions divided according to weight of each output | Products are similar in function or value |
| Economic | Emissions divided by market value of each output | Co-products vary greatly in price |
| System expansion | Credits assigned for avoided impacts of co-products | Outputs substitute other products or processes |
The method used can significantly affect results, so document your choice and reasoning.
Once emissions are calculated, prepare to report the final PCF. This will usually include:
Results can feed into a carbon label, internal decision-making, product redesign, or investor disclosures. Many companies also benchmark PCF data across suppliers or against industry standards.
Conducting product carbon footprint calculations manually is time-consuming, especially across multiple product lines, geographies, or suppliers. This is where carbon management software plays a transformative role.
Modern platforms integrate with ERP, procurement, and manufacturing systems to automate data collection. This reduces errors, increases data granularity, and allows companies to capture more primary data from across the product life cycle.
These tools include pre-loaded databases of emissions factors and apply them accurately to input data. The result is faster, more consistent, and audit-ready PCF results that align with standards like ISO 14067 and the GHG Protocol.
Many tools allow companies to run simulations to see how design or supply chain changes would affect the product carbon footprint. For example, switching from virgin plastic to recycled material, or changing a supplier’s energy mix, can be modelled and compared directly.
This allows businesses to weigh the carbon benefit of potential changes before implementation, supporting more strategic decarbonization decisions.
Carbon management tools store detailed records of inputs, assumptions, and calculations. This makes it easier to verify results for internal use, investor confidence, or third-party certification.
They also support the creation of standardized outputs such as:
Once PCF models are developed, businesses can scale their methodology across hundreds of SKUs, suppliers, or locations. This capability is essential for large manufacturers or retailers seeking portfolio-wide carbon insights.
