Is there a template for creating EPDs?

Yes, you can download the template here.

What is the validity of an EPD?

An EPD is valid for five years. That is from the date of registration until a final validity date which is declared in the EPD.

Is it possible to group several products in the same EPD?

This is possible under the condition that average result for GWP-total should not differ by more than ±10 % compared to the GWP-total results for any of the covered products.

Several sets of results are not allowed to be declared in the same EPD. However, similar products from a single or several manufacturing sites covered by the same PCR and manufactured by the same company with the same major steps in the core processes may be grouped and thereby included in the same EPD. For such an EPD, there are three options:

  • For each indicator, declare the average results of the included products. This average shall be weighted according to the production volumes of the included products, if relevant. In this option, the average content shall be declared in the content declaration.
  • Declare the results of one of the included products – a representative product. The choice of the representative product shall be justified in the EPD, using, where applicable, statistical parameters. For example, the choice may be based on production volumes. In this option, the content of the representative product shall be declared in the content declaration.
  • For each indicator, declare the highest result of the included products (i.e., the results of a “worst-case product”, which may be the results of one or several of the included products). In this option, the content declaration shall include the lowest amounts of recycled and biogenic content of the included products and their packaging, respectively, and the information on environmental and hazardous properties of substances shall reflect the highest share and most hazardous such substances contained in the any of the included products.

What makes the EPD complies with ISO 14205/ EN 15804?

There are 3 things to look for:

  1. The EPD should mention a programme operator.

    According to ISO 14025 and EN 15804 guidelines, an EPD should make reference to the EPD program under which it is registered. The program operator bears the responsibility of ensuring that its documentation meets standard requirements. The program operator, tasked with various duties, aims to uphold transparency and credibility in declarations. As part of its obligations, the program operator maintains a public register of all registered EPDs, making it easy to verify the validity of an EPD by accessing the operator's website or contacting them directly.

  2. The EPD should clearly state the PCR used.

    AThe program operator ensures that the PCR adheres to ISO standards. The PCR document guarantees uniform development and presentation of EPDs within the same product category, while also providing insight into the life cycle assessment methodologies employed. The program operator maintains a record of PCR documents developed within the program.

  3. The EPD should clearly state the third party verifier.

    An EPD should feature information regarding the verification process. Most EPD programs mandate third-party verification, and the EPD should specify the verifier's name, whether an individual or organization, along with the validity date.

These criteria serve as essential benchmarks for assessing the credibility and compliance of purported EPDs with established environmental standards.

What is a PCR?

Product Category Rules (PCR) provide rules for how to develop an EPD for a specific product category, including instructions for the underlying life cycle assessment (LCA) and other content of the EPD.

PCRs are developed in the framework of a programme operating in accordance with ISO 14025.

Can I register an EPD for a product with less than 1 year production data?

Typically, LCI data should derive from at least one year of production records. However, if such data isn't accessible due to the product's production duration being less than a year, LCI data might rely on a shorter timeframe (e.g., three months), provided it's demonstrated to be either conservative or representative of a full year's data. In such instances, the product description must include a disclaimer stating "Product recently on the market – LCI data is not yet based on 1 year of production," and the EPD should undergo an update and re-verification once one year of production data becomes available.
