What is an Environmental Product Declaration?
An Environmental Product Declaration (EPD) is a uniform document that provides clear and verified information about a product’s environmental impact throughout its lifecycle. It measures the environmental data concerning energy use, raw material sourcing, emissions, waste generation, etc.
To understand the stages of a product lifecycle, refer to our blog on Fashion Life Cycle.
EPDs are of great significance in sustainability as they help companies with a comparable and transparent set of data. This data can help them understand a product’s environmental footprint. Businesses make use of EPDs to showcase their dedication to sustainability, whereas consumers rely on them for making informed decisions.
For example, EPDs can show how much CO2 a product releases in its entire lifecycle. Companies can subsequently set and achieve emission reduction targets.

The Role of EPDs in Green Building and Product Transparency
EPDs are crucial to green building certifications like LEED (Leadership in Energy and Environmental Design) and BREEAM (Building Research Establishment Environmental Assessment Method). These certifications require environmental assessments of building materials. EPDs help meet these stringent standards by providing essential data.
For example, LEED rewards points for using products with EPDs. These points can help get to higher certification levels.
EPDs help boost transparency in environmental impact assessments by providing third-party-verified data. This helps build credibility in the market and ensures sustainability claims are authenticated. Companies can showcase genuine environmental responsibility through EPDs and combat the growing concern of greenwashing.
Companies can also gain a competitive edge in the market by attracting eco-conscious consumers with the help of EPDs.
Key Components of an EPD
Core Elements of an EPD
Product Description and Lifecycle Stages
An EPD consists of a detailed description of the product and its primary functions. This involves information about the product’s composition, manufacturing process, and intended use. After this, the EPD consists of the product’s lifecycle stages.
The stages are classified into: raw material extraction, manufacturing, transportation, use, and end-of-life disposal. Each stage is examined to evaluate its environmental impact.
Environmental Impact Categories
- Global Warming Potential (GWP): This estimates the amount of greenhouse gases released by a product, and evaluates the product’s contribution to climate change. GWP is expressed in CO2 equivalents.
- Water Usage: This measures the amount of water consumed throughout a product’s lifecycle. This is crucial in areas of water scarcity.
- Ozone Depletion Potential (ODP): This assesses the amount of chemical usage in a product’s lifecycle that can impact the ozone layer.
- Eutrophication Potential: This measures the extent to which a product contributes to water pollution. It can result in harmful algae blooms in aquatic ecosystems.
Standards and Frameworks Governing EPDs
EPDs are created according to stringent international standards, like the ISO 14025. This standard highlights the principles and practices for creating Type III environmental declarations. EPDs fall under these environmental declarations. ISO 14025 ensures EPDs are clear, reliable, and comparable across different products and markets.
ISO 14040 is another significant standard that outlines guidelines to conduct lifecycle assessments (LCA). These guidelines form the basis of an EPD while providing a consistent methodology. This way, all EPDs are developed with the same level of accuracy.
The Role of Product Category Rules (PCR) in EPD Development
Product Category Rules (PCR) are a set of specific rules that outline how to conduct a lifecycle assessment. It also highlights what to include in an EPD for a specific product category. PCRs make sure EPDs remain the same and can be compared within the same product category. For example, a PCR for concrete would only highlight how to measure and report the environmental impacts of various concrete products.
PCRs are prepared through a collaborative effort of stakeholders. Often, there are competitors involved to ensure fair play and the best use of available science. It would be difficult to compare EPDs without PCRs, as they provide systematic criteria.
Why are Environmental Product Declarations Important?
Benefits of EPDs for Businesses and Consumers
Environmental Product Declarations (EPDs) majorly boost the credibility and scalability of products. Businesses can provide reliable proof of their product’s environmental impact through EPDs. This way, they can also gain a competitive edge in the market by differentiating themselves. This helps build consumer loyalty and opens up new markets where people are environmentally conscious while purchasing.
In a study by the World Business Council for Sustainable Development, it was found that products with EPDs are preferred over ones without EPDs. They drive better sales and brand loyalty.
Consumers can have access to clear and credible information concerning the environmental impact of the products through EPDs. They can make better decisions that are in line with their sustainability goals and values. A Nielsen survey says that 73% of global consumers would change their consumption habits to reduce their environmental impact.
EPDs make use of this by providing consumers with credible data like the product’s carbon footprint or water usage.
EPDs and Regulatory Compliance
Businesses can meet their regulatory requirements and achieve their sustainability goals through EPDs. Global standards like ISO 14025 demand that EPDs be based on detailed lifecycle assessments (LCA). This is to make sure all environmental impacts are taken into consideration.
Adhering to these ISO standards supports broader corporate sustainability plans and helps meet regulatory requirements.
For example, in the European Union, regulations like the Construction Products Regulation (CPR) promote the use of EPDs. This is to ensure that building materials meet environmental performance standards. Businesses that provide EPDs with their products meet regulatory standards and avoid fines or penalties.
EPDs are rapidly becoming essential in industries where environmental impact is an issue. In Sweden, the law demands EPDs for particular construction materials. This is done to ensure transparency in environmental reporting.
In the automotive industry, car manufacturers are seeking to meet stringent emissions regulations and hence EPDs are crucial. The EU’s End-of-Life Vehicles Directive promotes the use of EPDs to showcase that vehicles are designed with environmental considerations in mind.
EPD Standards and Rules
EPDs follow rules such as ISO 14025 and EN 15804 that help to maintain the accuracy of the environmental data provided. EPDs must follow these standards to be created and disseminated and therefore must consist of a Life Cycle Assessment, which measures the environmental effects of the product through its entire life span. The aim is to disseminate accurate, evidence-based knowledge in a similar, easily comparable style.
Another principle of EPDs is compliance with Product Category Rules (PCR), which apply to a particular product group. PCRs prescribe the rules on how LCAs should be conducted and EPDs developed, especially for related products. They assist in the standardization of the existing measuring instruments by determining what data is to be collected, how the impacts are to be measured, and how the results are to be reported, enabling easier comparisons of products that fall under the same category.
Verification is another important factor, since EPDs have to receive third-party verification to guarantee compliance with appropriate standards and PCRs. This verification procedure would improve the reliability of EPDs and enable other stakeholders such as businesses, consumers, and regulators to use them as tools to determine and distinguish better sustainable products.
How to Develop an Environmental Product Declaration
Steps in the EPD Development Process
Conducting a Life Cycle Assessment (LCA)
To prepare an Environmental Product Declaration (EPD), the first step is to conduct a Life Cycle Assessment (LCA). An LCA assesses the product’s environmental impact throughout its lifecycle. This is done from raw material extraction to manufacturing, distribution, use, and end-of-life disposal. This detailed assessment helps in recognizing hotspots in the product’s lifecycle. These hotspots could be energy consumption, greenhouse gas emissions, water usage, or waste generation.
The precision and scope of LCA is critical as it forms the base of an EPD.
Gathering Data and Adhering to Product Category Rules (PCR)
After LCA is completed, the next step is to collect detailed data on each stage of the product’s lifecycle. The data should be product-specific and showcase real production processes. Product Category Rules (PCR) offer standardized guidelines on how to perform LCA and what to include in the EPD. It is essential to follow the PCR during the process.
Staying compliant with PCRs is significant so that the EPD meets industry standards and is credible for stakeholders.
