LCA vs. PCF vs. EPD: What Are the Differences and When Do You Need Which Tool?
LCA vs. PCF vs. EPD: Anyone working with product environmental impact will quickly come across these three abbreviations. But what do they mean? When does each tool make sense? This article gives you an overview. Plus: What role does the CCF play?
LCA vs. PCF vs. EPD: an overview
Before we take a closer look at each tool for calculating and presenting product environmental impact, we want to give you a brief overview in table form. This way, you can see at a glance what to consider when comparing Product Carbon Footprint vs. Life Cycle Assessment vs. Environmental Product Declaration.
| PCF | LCA | EPD | |
|---|---|---|---|
| Written out | Product Carbon Footprint | Life Cycle Assessment | Environmental Product Declaration |
| What does it measure? | Greenhouse gas emissions from a product, expressed in CO₂e | Multiple environmental impacts: climate, water, resources, acidification, land use, and more | A product environmental profile, third-party verified and published |
| Standard | ISO 14067 | ISO 14040, ISO 14044 | ISO 14025, EN 15804 (construction) |
| Verification | Optional | Optional | Mandatory third-party verification |
| Impact scope | Climate | Multiple impact categories | Multiple, depending on the product category |
LCA vs. PCF vs. EPD: the tools briefly explained
Let’s now take a closer look at PCF, LCA, and EPD. PCF, LCA, and EPD all describe product environmental impacts, but in different ways. One measures only climate impact, another covers a whole set of impacts, and the third presents results in a publicly comparable format. If you mix them up, you may end up providing too much or too little. Here are the three in detail:
Product Carbon Footprint (PCF)
The Product Carbon Footprint (PCF) measures only a product’s greenhouse gas emissions, expressed in CO₂e. The established standard here is ISO 14067. A PCF is especially useful when customers ask for specific CO₂ values, CBAM data is required, or a climate hotspot needs to be identified. By the way: The PCF should not be confused with the Corporate Carbon Footprint, which refers to the entire company. However, the PCF can feed into the CCF.
Life Cycle Assessment (LCA)
When it comes to LCA vs. PCF, one thing is clear: the Life Cycle Assessment goes far beyond the PCF. It looks not only at climate impact in the form of emissions, but also at water consumption, resources, acidification, and land use. Common standards here include ISO 14040 and ISO 14044. When deciding between Product Carbon Footprint vs. Life Cycle Assessment, the LCA is especially useful when you want to make product decisions across several environmental impacts, for example in redesign or material selection.
Environmental Product Declaration (EPD)
When comparing LCA vs. PCF, the EPD also comes into play. An Environmental Product Declaration is a third-party verified, public document based on an LCA. The classic standard for this is ISO 14025, while construction products, for example, are also subject to EN 15804. An EPD is often necessary when you want to communicate environmental data externally — in tenders, for building certifications, or to customers who require verified comparability.
Put simply: The LCA is the comprehensive method for calculating product environmental impact. The PCF is the climate-related part within the LCA. And the EPD is the verified format for public communication.
And the CCF?
The Corporate Carbon Footprint (CCF) does not quite fit into the LCA vs. PCF vs. EPD comparison because it does not look at a single product, but at greenhouse gas emissions from an entire company. It is calculated across Scopes 1, 2, and 3 based on the GHG Protocol, from office heating to the supply chain. PCF and CCF complement each other: product data from the PCF can feed into the Scope 3 part within the CCF. You can learn how to calculate your Corporate Carbon Footprint in our blog post on the CCF.
LCA vs. PCF vs. EPD: Which one do you need when?
Whether a PCF is enough or whether you need an LCA or EPD depends on the reason behind the request: Who is asking, what are the data needed for, and what format must the results ultimately take? This is a good way to determine whether a PCF is sufficient, an LCA is necessary, or an EPD is required. Three questions usually lead you to the answer quickly:
1. Who is asking, and for what purpose?
If the request comes from a customer’s procurement team, it is usually about CO₂ data for that customer’s own Scope 3 inventory or supply chain reporting. A PCF is sufficient. If it is about a public tender or building certification, an EPD is usually required. If it is about internal product decisions, an LCA provides the more robust basis.
2. Is a CO₂-only view enough, or do several environmental impacts need to be considered?
For CBAM, decarbonization strategies, and most customer requests, the PCF is sufficient. Anyone comparing materials, rethinking packaging, or assessing circular solutions will not get far with climate data alone. In those cases, the LCA is the right tool.
3. Do the data need to be publicly comparable in a standardized format?
Not for internal management and most customer requests. But they do for tenders, building certifications, or market communication where products are directly compared. This is exactly where the EPD shows its strength: uniform product category rules make products within the same category truly comparable.
How are PCF, LCA, EPD, and CCF connected?
In brief:
- LCA vs. PCF is actually the wrong framing, because the PCF is part of the LCA: the LCA covers several environmental impacts, while the PCF focuses on greenhouse gas emissions.
- And the EPD is not a fully separate tool either. The EPD brings LCA results into a standardized, public format.
- The CCF sits one level higher, at company level. PCF and EPD provide product data for its Scope 3 inventory.
PCF, LCA, EPD, and CCF do not simply stand side by side; they build on each other. The LCA is the method behind the scenes: it assesses a product’s environmental impacts across its entire life cycle. The PCF is one impact category within the LCA, namely global warming potential, expressed in CO₂e. The EPD, in turn, presents LCA results in a standardized, third-party verified, and public format.
The CCF looks at a different level: not a single product, but company-wide emissions across Scopes 1, 2, and 3. This is where the connection to the product closes the loop, because product data from the PCF can feed into the Scope 3 part within the CCF.
One data foundation for PCF, LCA, EPD, and CCF
PCF, LCA, EPD, and CCF do not compete with each other; they answer different questions. Which tool you need depends on the occasion, and over time you will often need several of them: a PCF for a customer today, an LCA for a redesign tomorrow, and later an EPD for a tender. The better you understand the differences, the more precisely you can deliver what is needed without wasting effort.
What connects all four is the data behind them: they rely on largely the same product data or build on one another. Once you have reliably collected a product’s CO₂ value, you have already completed a large part of the work needed for the LCA, and those results in turn form the basis for an EPD. The real effort rarely lies in the individual proof point, but in building a robust, traceable data foundation. If the data is scattered or incomplete, every new request starts from scratch. If it is well-structured and available, the right proof point can be derived depending on the occasion.
