The EPD is a ISO type III Environmental Declaration acc. ISO 14025 standard
As that, the EPD differs in many aspects from ISO type I third-party (independent eco-labels) and type II self-declared eco-labels. No secret, the EPDs relevance is steadily growing in voluntary and mandatory engagements.
Watch this short video and learn!
An Environmental Product Declaration (EPD) transparently reports objective, comparable and third-party verified data about products and services' environmental performances from a lifecycle perspective.
Where the EPD is the final report, the foundation of any EPD is a lifecycle assessment (LCA). This LCA allows you to evaluate your product’s environmental performance over its entire life-cycle. It typically takes into consideration your full value chain, from material extraction through to manufactured product, its usage stage and end of life.
An EPD is a so-called type III environmental declaration that is compliant with the ISO 14025 standard. A type III environmental declaration is created and registered in the framework of a programme, such as the International EPD® System. EPDs registered in the International EPD System are publicly available and free to download through the EPD Library, accessible via this link.
In physical terms, an EPD consists of two key documents:
As a voluntary declaration of the life-cycle environmental impact, having an EPD for a product does however not imply that the declared product is environmentally superior to alternatives.
Following we present a short summary conveying an (your?) EPD's value!
EPDs are based on International Standards
The concept of EPDs is based on the standard ISO 14025, which is internationally recognized and developed with in the International Organization for Standardization.
EPDs consider the full Life Cycle Assessment of goods and services
Compared to alternative reporting formats such as eco-labels and self-declared labels that only cover aspects of a lifecycle perspective, EPDs cover the full LCA of goods and services.
EPDs can be used for all types of goods and services
There are no restrictions regarding what products that can have EPDs as there are no criteria on environmental performance that must be met. EPDs works for both goods and services and companies all sizes have registered EPDs.
EPDs contain verified environmental information
The EPD is a third-party verified document which gives the information credibility and therefore is very suitable for procurement.
EPDs are based on a robuts, transparent and open framework
ISO 14025 requires the programme operator to publish the programme instructions, product category rules and registered EPDs. The transparent framework makes it possible to understand the calculations and methods behind the results in the EPD.
EPDs gives comparable information within the same product group
EPDs that are based on the same product category rules (PCR) are comparable as the PCR set the rules for the life cycle assessment that the EPD must meet, for example allocation rules, data quality requirements and system boundaries.
EPDs communicate sensitive commercial information, correct?
No, this is absolutely not the case!
Factually, as little as it is correct that surströmming, a Swedish delicacy, tastes worse than it smells...
The public EPD document does not include sensitive commercial details of e.g. your own manufacturing processes or up and down-stream supply chain partners and activities. An EPD is used to communicate the life-cycle assessment results, only. The public EPD that is published via the EPD Portal/website does not contain any such specific details.
Now want to try surströmming?
Please do not open the can indoors! Your neighbours will love you...
An EPD (Environmental Product Declaration) is a verified and registered document that communicates transparent and comparable information about the life-cycle environmental impact of products.
Having an EPD for a product does not imply that the declared product is environmentally superior to alternatives — it is simply a transparent declaration of the life-cycle environmental impact.
An EPD is created and registered in the framework of a programme based on ISO 14025, such as the International EPD® System.
Developing and publishing an EPD in The International EPD® System consists of the following steps:
The two most time-consuming steps are to create a PCR (if not already available) and to perform the underlying LCA study. Developing a PCR in an open and transparent process normally takes between 5-12 months. Conducting an LCA study in accordance with the PCR may take anywhere between 1-12 months depending on the availability of data and the amount of LCA work that has been done in the company to date. If a PCR is being developed, the LCA study may be carried out in parallel to drafting the document.
It is recommended to make contact with a potential verifier early on in the process so that this step may start as soon as the LCA study is done and the information compiled into the EPD reporting format.
After verification is completed, registration by the Secretariat upon receiving the complete documentation normally takes 1-3 working days. The Secretariat may assist with Helpdesk and pre-booking of an EPD registration number throughout the process.
The International EPD® System has two types of fees: registration fee (one-time fee, which includes future updates) and an annual fee paid per organisation.
In addition to these fees, the total cost of an EPD also includes:
There is no fee for updating already-registered EPDs for EPD registrations via the EPD International Secretariat. This is included in the annual fee.
For EPD registrations in countries where registration is done via a fully aligned regional programme (currently: Australia, Brazil, Chile, India, Mexico, New Zealand, Russia, Souteast Asia and Turkey), please check their website for up-to-date details.
Yes, a voluntary EPD template is available under Resources. The current template is only for non-construction products.
The use of the template is voluntary, as companies are free to use their own branding in the EPD.
No, publishing an EPD in multiple languages is included in the registration fee for EPD registrations via the EPD International Secretariat.
For EPD registrations in countries where registration is done via a fully aligned regional programme (currently: Australia, Brazil, Chile, India, Mexico, New Zealand, Russia, Souteast Asia and Turkey), please check their website for up-to-date details.
The Secretariat recommends the following three dates to be displayed in an EPD:
"Publication date" (sometimes referred to as "issue date" or "registration date"). This date is set as the date when the company submit the EPD registration. In case the documentation is incomplete or contains errors, the publication date on the EPD should be updated to correspond to the date of the final resubmission for registration. This date remains the same even with later updates of the EPD.
"Revision date". In case of a new version of an already-published EPD, this date should be set corresponding to the date when the updated EPD is submitted for publication. It should not be included in case of a first EPD edition.
"Validity date". This date is set during verification as normally +5 years (depending on rules in PCR) from the finalization of verification/date of the verification report.
An EPD is valid from completion of the last step of the EPD process (Registration & publication) until a final validity date, which is declared in the EPD.
The EPD validity is normally five years. An expired EPD can still be published to give environmental information for products still in use, but may not been used in marketing.
Regardless of the validity, a published EPD shall be updated during its validity if one of the environmental indicators has worsened for more than 10% compared with the data currently published.
Rules for including multiple similar products in the same EPD can be found in Section 9.3 of the General Programme Instructions. These rules are also listed below, with some specifications and changes that will be implemented in the next update of the GPI, to be released towards the end of 2022.
Note that a specific PCR may include deviations or specifications to these rules. Further, some PCRs are based an old version of the General Programme Instructions (version 3.01 or older) in which the rules may be different from the current version - we still recommend following the current version, as all PCRs will be updated according to this.
Several sets of results, reflecting different products, 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.
The first two options are only possible if none of the declared environmental impact indicator results differ by more than 10% between any of the included products. The third option is possible also if variations are larger than 10%.
The option chosen shall be clearly described in the EPD.
In addition to above options, sector EPDs are possible. See more in Chapter 9.3.2 of the GPI.
For EPDs following version 1.1 of PCR 2019:14 Construction products, the 10% difference only applies for the GWP-GHG indicator and for modules A1-A3, and larger variations may be accepted if justified and if the variation is declared.
If the PCR is based on an old version of the GPI (version 3.01 or older), the EPD may include several products/product groups even if above requirements are not fulfilled, but then the results of each product/product group shall be separately declared. If the PCR is based on the current version of the GPI (version 4.0 or later), the EPD shall include not more than one set of results. This change of rules was done to improve machine-readability of EPDs and thereby facilitate digitalisation of the EPD system. To enable this change, the cost per EPD registrations was reduced significantly as of 1st January 2021. Even if older versions of the GPI allow the declaration of results for several products/product groups, we recommend you to declare no more than one product or average/representative product per EPD – to be prepared for a more digital future.
Note that you are not allowed to include a conversion factor in the EPD for the purpose of converting the declared results into results for products not covered by the EPD. The EPD is for a specific product or product group, and only the EPD content of that product/product group has been verified and may be considered EPD information. You may, however, include a conversion factor for other purposes, see the answer to the question "May conversion factors be included in the EPD?".
We recommend that the EPD document is maximum 10 MB. PDF files can often be made smaller when saving from the layout application or by resaving the finalized PDF file.
EPDs are published by a programme operator following the ISO 14025 standard. All EPDs via the International EPD® System are published and freely accessible via our search portal. Since the start, more than 1800 EPDs have been published in the International EPD® System from organizations all around the world.
Besides the International EPD® System, EPDs can also be published by other programme operators and the EPDs should be available via their respective website. There are current and past initiatives to allow searching across the databases of multiple programme operators, such as the InData working group.
The standard output format of an EPD is a PDF document containing the information as mandated by the General Programme Instructions and the relevant Product Category Rules. This information consists of indicator results from the LCA study, but also other verified quantitative and qualitative information about the product, the company and the environmental impact. An EPD is thus more than the LCI/LCA indicators, but they form an important sub-set of the EPD.
EPD owners are welcome to publish the LCA/LCI information in parallel with the EPD at www.environdec.com or elsewhere for import into LCA software such as GaBi, SimaPro or openLCA.
An EPD provides relevant and verified information to meet the various communication needs. This may be relevant within the supply-chain and for end-products both in the private and public sector, as well as for more general purposes in information activities and marketing.
The potential uses and application include:
The interest for environmental declarations in building rating systems and certification schemes has increased in the last few years. This may be due to recognition of EPD benefits such as the life cycle approach, the transparent disclosure of relevant impact categories and the independent verification.
LEED by the US Green Building Council (USGBC) is one of the schemes that have come the furthest in giving benefits for projects where EPDs are available to encourage the use of products with life-cycle information. In LEED v4 introduced in November 2013, two "points" are possible for projects that have product-specific declarations such as EPDs available and that demonstrates an impact reduction compared to an industry average. More information is available on the USGBC site: http://www.usgbc.org/credits/new-construction-core-and-shell-schools-new-construction-retail-new-construction-healthca-22
BREEAM has several national implementations where the requirements are somewhat different. Normally, only pre-approved national databases of LCA information are accepted. Please contact your local BREEAM national scheme operator for more information: http://www.breeam.org/
There are also other national and international building rating and assessment schemes that may or may not accept EPDs as part of their scope.
The International EPD® System is based on ISO 14025 (environmental declarations) and EN 15804 for applicable EPDs and PCRs. As a founding member of ECO Platform, the system works on harmonization efforts for EPDs for construction products across Europe. The International EPD® System is allowed to give the right to use the ECO Platform logotype on EN 15804-compliant EPDs for construction products during registration.
There are three main methods on how to use EPDs in public procurement:
1. To obtain environmental information on the product. To get information on the environmental impact from the goods and serviced being procured can be seen as the first step in greening the procurement activities. Knowledge about the impact of the subject matter is vital in order to be able to put down relevant GPP criteria in the tendering documents. EPDs can therefore give very useful input to GPP, either in the market analysis or as a first step in greening the GPP.
Information obtained from the EPDs can also serve as environmental information to different stakeholders.
2. As verification on environmental requirements in the tendering documents. As the EPDs contain information on the products environmental impact in a life cycle perspective, the EPD can be used to verify compliance provided that the environmental requirements put in the tendering documents is information that can be found in an EPD. Examples on such requirements are:
3. To reward the environmentally best product. Information in EPDs within the same product group and based on the same PCR can also be used to compare products from an environmental point of view and also to reward the environmentally best product. This must be done according what is allowed in the legislation and the reward criteria must be transparent and non-discriminatory.
For our quality management it is very important that the Secretariat get information if there are any irregularities with EPDs, PCR or other published documents. To file a complaint, send an e-mail to the Secretariat: firstname.lastname@example.org.
To handle the complaint we need information about name, registration number, etc. of the document complained of. The complaint also must be clear in what way the document not meets the requirements in GPI, ISO 14025, EN 15804 or other steering document.
Anonymous complaints are not considered.
An EPD is a type III environmental declaration according to ISO 14025 or EN 15804. However, on the market there are other documents that could be mistaken for being type III environmental declarations, but rather should be seen as self-declarations or the results from LCA studies. Such documents are lacking some important characteristics of EPDs that are conformant with the standards.
Here are three important things to look for when reading a document claiming to be an EPD, with or without a reference to ISO 14025 or EN 15804:
Reference to an EPD programme According to ISO 14025 and EN 15804, the EPD shall refer to the EPD programme under which it has been registered. The EPD programme operator is responsible for making sure that its documentation fulfills the requirements in the standards. The programme operator has many duties to fulfill, and is intended to ensure transparency and credibility in the declarations. As the programme operator shall maintain a public register over all registered EPDs it is also easy to check the validity of the EPD by visiting the website of the program operator or by contacting the operator.
Reference to product category rules (PCR) The EPD shall also refer the PCR-document that has been used for the EPD development. The programme operator is responsible for that the PCR is developed according to the ISO standard. The PCR document ensures that the EPDs within the same product category are developed and presented in the same way and also gives information on the methods used in the life cycle assessment. The programme operator shall maintain a record over the PCR documents developed within the programme.
Information on the verification The EPD shall have information on the verification process. Most EPD programmes requires a third party verification and the EPD shall contain information on the name of the verifier, which can either be a person or organisation. The EPD shall also give information on the validity date.
Incorporating data from EPDs into software platforms is currently ongoing discussion internationally.
For EPDs compliant with EN 15804, the International EPD® system allows the publication of a machine-readable LCA dataset in parallel to the EPD.
If an EPD owner wishes, the International EPD® system allow the publication of a machine-readable LCI dataset in parallel to the EPD. Such data sets are available on the individual EPD page and may be produced in multiple of the available formats currently available on the market. For machine-readable LCA datasets, the International EPD® system recommends following the format solutions that are compatible with the International EPD® system data hub and formats following developments from the InData working group.
Questions or suggestions on how the International EPD® system may enable or facilitate the use of EPDs may be sent to the Secretariat.
Environmental claims are under hard scrutiny to ensure that consumers are not misled. The ISO standards in the 14020-series gives guidance focusing on things like the correctness of information (not being misleading), using scientific methods, using the life cycle perspective, transparency and including all relevant environmental aspects.
The contents in the EPD must be in line with the requirements and guidelines in ISO 14020. Any environmental claims based on the EPD is recommended to meet the requirements in ISO 14021 and national legislation and best available practices in the markets in which it will be used. The international standard ISO 14021 states that only environmental claims that can be supported by up-to-date and documented facts may be used. Vague claims about a product such as "environmentally friendly" should be avoided.
A Climate Declaration is single-issue declaration focused on the carbon footprint of the product. The emissions of greenhouse gases of a product are reported in kg CO2 equivalents from the different life cycle stages of the product.
Climate Declarations may be published based on a registered EPD, or if the full information about the other types of environmental impact of the product is available upon request. The Climate declaration shall give information on how to obtain information on the full environmental impact from the declared product.
Environmental declarations and environmental labels are tools that serve similar purposes but provide complementary information, depending on the purpose and target audience of the information. Both are voluntary instruments based on international standards and independent verification.
An EPD provides verified, objective and detailed information about the life cycle environmental impact of a product. Having a certified EPD does not imply any environmental advantage of the product itself, only that the presented information has been verified to comply with the rules set out in the General Programme Instructions and the relevant Product Category Rules. The reference standards are ISO 14025 for the management of a programme for type III environmental declarations and ISO 14040/14044 for the procedure to carry out a life cycle assessment (LCA).
An environmental label (type I) according to ISO 14024 is a third-party verified demonstration that the product fulfils certain environmental criteria as defined by the programme owner. The design of the programme is normally such that only a certain share of the market will fulfil these requirements, and thus intend to drive the market into a direction with a lower environmental impact.
Different stakeholders currently refer to slightly different things when referring to the use of "EPD tools". The International EPD® System has several options for cost-effective EPDs:
The International EPD® System does not currently offer any way to create a fully automated EPD tool, from which the output may be published directly as an EPD. The reason is that such an approach would not have any verification in the way the tool has been used nor on the data input to the tool.
A company is very welcome to create and use an internal or external tool to use in carrying out an LCA. Such a tool needs no approval from the programme to be used, and the results and the EPDs based on the results are verified in the same way as though the calculations had been done in dedicated LCA software (SimaPro, GaBi, etc.).
The International EPD® System also offers these possibilities that are similar to what is referred to as "EPD tools" by some stakeholders:
A company may use an internal LCA tool as part of its EPD Process Certification. When using a tool together with a certified process or routines for making an EPD, this replaces external verification of each EPD.
An industry association may develop a pre-verified EPD tool to be used by its members. Such a tool would simplify LCA calculations as the tool would be verified to produce correct results based on a correct input. The resulting EPD would, however, still need to be verified.
Please contact the Secretariat at email@example.com for more information.
Performing a Life Cycle Assessment (LCA) in accordance with the relevant Product Category Rules (PCR) is one of the largest tasks in the process to create an EPD. If such expertise is not available in-house, a consultant is often employed to assist and work with the company to collect the relevant data, model the product life cycle and calculate the results.
In its role as the programme operator according to ISO 14025, the Secretariat does not recommend any specific company or person for you to perform the Life Cycle Assessment.
As a service to companies and consultancies to more easily find each other, we have prepared a list of potential consultancies to consider under Resources.
In order to find the most suitable LCA practitioner for a specific project, it is recommended that companies ask for tenders from several potential candidates.
No, the European standard EN 15804:2012+A1:2013, “Sustainability of construction works - Environmental product declarations - Core rules for the product category of construction products” is limited to construction products. It is thus not applicable or used for EPDs of for example food and beverages.
For many key aspects, however, the International EPD® System has aligned with the standard for all product categories. This includes a five year validity of all EPD (instead of the previous three years ) and the main environmental indicators.
A manufaturer may link to their EPD in the International EPD System by using the format https://www.environdec.com/Detail/epdXXXX, where XXXX is replaced by the digits of the registration number.
Example: The EPD S-P-01234 is available via https://www.environdec.com/Detail/epd1234.
There is also an automatically-generated QR code on each EPD page that may be used to provide a link to the EPD page.
The requirements for comparability of EPDs are set in Section 6.7.2 of ISO 14025. They involve the two EPDs covering the same product category, LCA methodology, environmental, indicators, additional environmental information, life cycle stages covered, EPD validity, etc.
Achieving these requirements is most easily met by two EPD registered based on the same Product Category Rules developed based on the general LCA methodology in the same EPD programme. Other EPDs may also fulfil these requirements, but this puts additional requirements on the reader of the EPD to understand if the information is comparable or not.
For construction products, Section 5.3 of EN 15804 sets additional requirements for comparability, e.g. that the EPD shall be cover the full life cycle and be in the building context to provide a tool of comparison.
The results of normalization are not allowed to be reported in an EPD.
A pre-certified EPD allows you to publish environmental information for a product that is covered by a PCR under development, in case the PCR is for a new product category. Pre-certification is not applicable for a product category in the event of an existing PCR (valid or expired).
A pre-certified EPD shall be based on the current version of the General Programme Instructions and be valid for at maximum one year. After this, the pre-certified EPD shall be updated based on the published PCR.
Read more about pre-certified EPDs in Section 6.1.1 of the General Programme Instructions.
Mass balance approaches are not allowed in the development of an EPD. Read more about our position on mass balance in Section A.4.2 of the General Programme Instructions.
No, biogas certificates is an example of a mass balance approach and as such it is not allowed in the development of an EPD. Read more about our position on mass balance in Section A.4.2 of the General Programme Instructions.
In general, LCI data shall be based on data from at least 1 year of production. If such data is not available because the product has not yet been produced for 1 year, the LCI data may be based on data from a shorter time period (e.g. 3 months) provided that the data can be proved to be conservative or representative for 1-year data. In such cases, the product description shall include a disclaimer saying "Product recently on the market – LCI data is not yet based on 1 year of production" and the EPD shall be updated and re-verified when data from 1 year of production is available.
When a product is made in whole or in part with biobased or recycled materials, the provenience of these materials (pre-consumer or post-consumer, in case of recycled materials) shall be presented in the EPD as part of the content declaration.
To avoid any misunderstanding about which material that may be considered “recycled material”, the guidance given in ISO 14021 shall be taken into account. In brief, the standard states that:
The declared share of biobased/recycled materials shall be based on the actual share of biobased/recycled material in the product (in average over the studied time period, normally 1 year of production). In other words, the share of biobased/recycled materials of, for example, global average production of the constituent materials, for example as stated in generic LCI datasets, shall not be used as the basis for the declaration of recycled content.
If the share of biobased/recycled materials is unknown, this part of the content declaration can be left out (unless otherwise required by the PCR) or it can be stated to be 0% (a conservative estimate) or unknown.
Yes, conversion factors may be included for the purpose of:
(i) converting the declared results of a product group to results for specific products within the group, or
(ii) converting the declared results to results for another declared/functional unit.
For conversion factors to be possible, the results of all declared life-cycle stages/modules must scale linearly with the conversion factor.
The conversion factors must be verifiable, i.e., the underlying data for the conversion factors must be provided in the LCA report.
The conversion factors shall be included in the section Additional environmental information, although they may be referred to in the Results section.
Conversion factors can, however, not be included for the purpose of converting the declared results into results for products not covered by the EPD. The EPD is for a specific product or product group, and only the EPD content of that product/product group has been verified and may be considered EPD information.
