Environmental Product Declarations (EPD): The Complete Guide for 2026

Environmental Product Declarations (EPDs) are fast becoming a business essential, not just a sustainability badge but a credible, verified way to communicate the full environmental story of your product.

If you’re a manufacturer, supplier, or specifier navigating low-carbon claims, procurement pressures, or green building standards, understanding EPDs is a smart place to start.

In this guide, we’ll break down what an EPD is, why it matters, and how it works, in plain English.

Whether you’re new to EPDs or ready to invest in one for your product, we’ll help you get to grips with the key terms, the process, and the real-world value they deliver.

What is an EPD?

An Environmental Product Declaration (EPD) is a standardised, independently verified report that sets out the environmental impact of a product across its life cycle, from raw materials and manufacturing to use and end of life.

Put simply, an EPD is the executive summary of your product’s environmental impact. It details impacts like carbon dioxide equivalent emissions, water use, acidification potential, and waste flows. It’s based on a rigorous life cycle assessment (LCA), follows international standards, and is designed to be transparent, comparable, and trustworthy.

An EPD doesn’t say whether a product is “good” or “bad”, it simply presents the facts, enabling more data-driven decisions and meaningful comparisons.

What does EPD stand for? Environmental Product Declaration
EPD meaning: a factual, third-party verified summary of environmental performance
Governed by standards such as EN 15804, ISO 14025, and ISO 14040/44
Used globally to support greener procurement, specification, and design
Applicable to a wide range of materials, products, and systems, from construction materials to packaging, consumer goods, and beyond

How Does an EPD Work?

An EPD is built on a process called Life Cycle Assessment (LCA), which is a detailed evaluation of your product’s environmental impacts at each stage of its life cycle. This includes:

Raw materials: extraction, processing, and supply
Manufacturing: energy, water, emissions, and waste
Transport and distribution: from factory gate to point of use
Use phase: energy or maintenance during product life (if relevant)
End of life: disposal, recycling, or reuse

The resulting data is compiled into a standardised EPD format, which includes a range of environmental indicators such as:

GWP (Global Warming Potential): your product’s “carbon footprint”
AP (Acidification Potential): the impact on ecosystems
EP (Eutrophication Potential): nutrient pollution in water systems
ODP, POCP, ADP: other technical metrics covering ozone depletion, smog formation, and resource depletion

An EPD report must be reviewed and verified by a third party to assure accuracy and comparability. Once approved, it’s published by a Programme Operator and made publicly available, typically for five years.

This level of rigour is what makes an EPD verified declaration a trusted resource across industries and borders, particularly where transparency and standardisation are required for compliance, procurement, or ESG reporting.

1. Scoping and Data Collection

Start by defining what product or range is being assessed, and gathering the necessary data including materials, energy use, waste, transport, and packaging. Accuracy and completeness are key here.

2. Life Cycle Assessment (LCA)

Model the resource and energy inputs and outputs of the product across its full life cycle, often using a cradle-to-gate plus end-of-life or cradle-to-grave boundary. The result is a detailed breakdown of environmental indicators.

3. EPD Report Creation

Format the LCA results into a standardised EPD format, in line with the relevant Product Category Rules (PCR). This ensures the data is consistent, credible, and comparable across similar products.

4. Independent Verification and Publication

A third-party verifier reviews the EPD to confirm it meets international standards (such as EN 15804 and ISO 14025). Once approved, it’s published by a recognised Programme Operator (e.g. EPD International, EPD Hub) and made publicly accessible, typically valid for 5 years.

Why EPDs Matter

An EPD is a strategic tool for any business serious about sustainability, carbon reduction, and market credibility.

Carbon and sustainability goals: EPDs quantify the carbon footprint and other impacts of your product, forming a credible foundation for your net zero and ESG reporting
Procurement and specification: Many public and private sector clients now require or reward EPDs in tenders, especially in sectors like construction, infrastructure, and healthcare
Supply chain transparency: With growing pressure to account for Scope 3 emissions, EPDs help position your product as a lower-impact, data-backed choice
Competitive edge: Being able to show independently verified environmental data can differentiate you in increasingly crowded markets
Policy and compliance: EPDs are aligned with standards like BREEAM, LEED, RE2020, and public procurement frameworks across Europe and beyond

In short, EPDs help you turn sustainability claims into facts, which builds trust with clients, regulators, and your own internal teams.

Who Needs an EPD?

EPDs aren’t just for sustainability teams or compliance specialists. They’re fast becoming a commercial tool for manufacturers, exporters, specifiers, and supply chain partners across multiple sectors.

You’ll benefit from an EPD if you are:

A manufacturer of building materials, packaging, furniture, or consumer goods looking to quantify and communicate product impacts
Supplying into infrastructure, construction, or public sector projects, where EPDs are increasingly required to win tenders or achieve certification credits (e.g. BREEAM, LEED)
Selling internationally, especially to countries like France, Germany, and the Nordics, where local EPD registration (e.g. INIES database in France) may be required
Part of a supply chain under pressure to provide product-level carbon data for ESG reporting, green building schemes, or lifecycle costing
A specifier or buyer seeking verified data to support procurement and material selection decisions

Whether your focus is compliance, client demand, or competitive advantage, having an EPD allows you to speak the same language as regulators, certifiers, and sustainability consultants and demonstrate a measurable commitment to responsible business.

Understanding Environmental Indicators in an EPD

At first glance an EPD results table can seem confusing. The scientific numbers look technical, the units unfamiliar, and the value unclear. But once you understand what the indicators mean and how they relate to real-world impacts, the data becomes a powerful decision-making tool.

For example, shipping a product by sea from the Far East may reduce GWP compared to road transport from mainland Europe, but increase acidification potential (AP) due to sulphur-rich marine fuels. This illustrates why a product’s carbon footprint is only part of the picture.

By understanding these indicators and how they relate to manufacturing decisions, logistics, and material choices, you can turn an EPD from a static document into a strategic sustainability tool.

GWP

(Global Warming Potential)

Measures carbon dioxide equivalents (kg CO₂e) across the life cycle. It’s the most commonly cited indicator in carbon reporting and net zero planning

AP

(Acidification Potential)

Shows how the product contributes to acid rain and soil degradation, influenced by sulphur dioxide and nitrogen oxide emissions from burning of fossil fuels.

EP

(Eutrophication Potential)

Highlights nutrient pollution in water, linked to fertilisers, wastewater, or agricultural runoff.

ODP & POCP

Ozone Depletion Potential and Photochemical Ozone Creation Potential

Covers impacts related to smog and atmospheric pollutants.

ADP

(Abiotic Depletion Potential)

Indicates the use of finite resources such as metals and minerals.

Common Challenges and How to Overcome Them

We’ve helped a wide range of businesses develop EPDs, from first-timers to multinational exporters. Here are the challenges that come up frequently:

Data quality and availability: Many companies worry they won’t have the “perfect” data. Your EPD provider will work with what’s available, identify gaps, and support you in building a realistic data model that reflects your operations while meeting EPD standards.
Time and cost pressures: An EPD takes time, but with good planning and the right support, it doesn’t have to derail other priorities. Your EPD provider will structure the project in manageable stages, helping you balance internal capacity with deadlines and commercial demands.
Internal and external stakeholders: Sustainability, marketing, technical teams, third-party verifiers, it’s a lot of moving parts. Your EPD provider will act as a bridge, helping align stakeholders around clear goals, a shared timeline, and a consistent narrative.

EPD vs. Other Sustainability Declarations: What’s the Difference?

EPDs aren’t the only way to report or communicate a product’s environmental performance, but they are among the most robust and standardised. So, how do they compare with other formats?

EPD vs. Carbon Footprint (e.g. PAS 2050): A carbon footprint typically measures only one indicator: Global Warming Potential (GWP), or kg CO₂e. It’s useful for climate-related targets but doesn’t provide a full picture of environmental impacts. An EPD, by contrast, includes GWP plus a range of other metrics such as resource use, water, waste, acidification, and more — and is subject to independent verification.

EPD vs. Environmental Labels (Type I, II, III): Type I labels (like EU Ecolabel or Blue Angel) are certification schemes based on predefined environmental criteria. Type II labels are self-declared claims (e.g. “eco-friendly packaging”). Type III labels are factual, data-driven declarations — and that’s where EPDs sit. They are based on independently verified LCAs and follow ISO 14025.

In short, EPDs are transparent, standardised, and verifiable, which makes them more credible in technical, regulatory, and procurement settings.

When should you choose an EPD?

When your clients demand product-specific carbon data
When entering public sector or certified building projects
When exporting to markets with formal EPD registration requirements
When you want to substantiate sustainability claims with data you can stand behind

Global EPD Requirements by Country

If you’re exporting or planning to enter international markets, your EPDs may need to be registered, adapted, or verified in specific ways to meet local regulations.

Some Programme Operators allow for mutual recognition (e.g. EPD International), some are internationally focused (e.g. EPD Hub) but it’s important to check the format, language, and scope required in each market.

As experienced EPD consultants, we regularly help clients navigate these differences, whether that’s getting EPDs into the INIES database for the French market or adapting it for LEED compatibility in North America.

UK

Not yet mandatory but increasingly expected on many larger private and public sector and infrastructure projects, often contributing to schemes like BREEAM. Strong market demand driven by competition amongst building product manufacturers.

France

Requires EPDs to be published in the INIES database to be valid for use in the RE2020 building regulation. French PCRs are often more detailed, and translations may be required.

Germany

EPDs are commonly used in public sector procurement and green building certification (e.g. DGNB).

Nordic Countries

High uptake of EPDs, particularly in timber, insulation, and furniture sectors.

USA & Canada

EPDs aligned with ISO standards are recognised in LEED and other sustainability frameworks.

What is an EPD in simple terms?: An Environmental Product Declaration (EPD) is like an executive summary of your product’s environmental impact. It tells you how much carbon, water, energy, and other resources are used across the product’s life cycle, all based on science and independently verified.
What does EPD stand for?: EPD stands for Environmental Product Declaration. It is a standardised report that shows the environmental performance of a product, based on a life cycle assessment (LCA).
What is the purpose of an EPD?: EPDs help manufacturers, buyers, and specifiers make more informed choices. They support green building certifications, help win tenders, and are increasingly used in private and public procurement and ESG reporting.
What’s included in an EPD report?: An EPD report includes data on things like embodied carbon, acidification, water use, and resource depletion, all measured over the life cycle of the product. It follows strict standards and is independently verified, so you can trust the numbers.
Is an EPD the same as a carbon footprint?: No. A carbon footprint only measures climate impact (in kg CO₂e). An EPD goes much further, it covers a full range of environmental indicators, including carbon, water, waste, and more.
Do I need an EPD for every product I sell?: Not necessarily. You can sometimes cover a product range in a single EPD if the impacts are similar. The key is understanding your product category rules (PCRs), the rules of the Program Operator where your EPD will be published and choosing the right scope.
How long does it take to get an EPD?: It depends on the complexity of your product and availability of your production data, but typically 3 to 6 months from kick-off to publication. We help you plan efficiently and avoid delays.
What does “verified EPD” mean?: A verified EPD means the data and methods have been reviewed by an independent expert, in line with international standards like ISO 14025. Verification adds credibility and ensures your EPD is accepted by clients, specifiers, and regulators.
Where can my EPD be published?: EPDs are usually published on a Programme Operator’s platform, such as EPD International, EPD Hub (International), INIES (France), or IBU (Germany) depending on your market. We can help ensure your EPD is correctly registered for your audience.
Can an EPD help me win more business?: Yes, especially in construction, infrastructure, and export markets where EPDs are required or highly valued. They also demonstrate leadership, transparency, and readiness for net zero supply chains.
What’s the format of an EPD?: EPDs follow a standard format or template, often based on a specific Product Category Rule (PCR) and the General Program Instructions (GPI) of the Program Operator who publishes the EPD. That ensures the data is structured, consistent, and comparable across similar products.
Can Blue Marble help me get an EPD?: Yes. We offer end-to-end support from data collection and LCA modelling to verification and publication. We help make the process clear, credible, and commercially useful, whether it’s your first EPD or your fifth.
