European foreword
This document (EN 15942:2021) has been prepared by Technical Committee CEN/TC 350 “Sustainability
of construction works”, the secretariat of which is held by AFNOR.
This European Standard shall be given the status of a national standard, either by publication of an
identical text or by endorsement, at the latest by May 2022, and conflicting national standards shall be
withdrawn at the latest by May 2022.
Attention is drawn to the possibility that some of the elements of this document may be the subject of
patent rights. CEN shall not be held responsible for identifying any or all such patent rights.
This document supersedes EN 15942:2011.
In comparison with the previous edition, the following technical modifications have been made:
— alignment of the content to the last amendment of EN 15804 (EN 15804:2012+A2:2019);
— revision of the general information table according to the content usually provided in EPDs;
— update of the tables to allow the declaration of more than one scenario per module;
— revision of the text to keep consistency with other CEN/TC 350 complementary standards.
This document has been prepared under a standardization request given to CEN by the European
Commission and the European Free Trade Association.
Any feedback and questions on this document should be directed to the users’ national standards body.
A complete listing of these bodies can be found on the CEN website.
According to the CEN-CENELEC Internal Regulations, the national standards organisations of the
following countries are bound to implement this European Standard: Austria, Belgium, Bulgaria, Croatia,
Cyprus, Czech Republic, Denmark, Estonia, Finland, France, Germany, Greece, Hungary, Iceland, Ireland,
Italy, Latvia, Lithuania, Luxembourg, Malta, Netherlands, Norway, Poland, Portugal, Republic of North
Macedonia, Romania, Serbia, Slovakia, Slovenia, Spain, Sweden, Switzerland, Turkey and the United
Kingdom.
Introduction
The aim of this document is to harmonize the way in which environmental product declarations (EPD)
are communicated in Europe.
It is relevant to the use of the EPD in the building chain where materials and products are assembled into
new products and assemblies, each with their own EPD.
This document will improve handling of the data from EPD at the building level and the assessment of
environmental performance of buildings.
An EPD expressed in a standardized format will facilitate the communication of the product's
environmental performance for business-to-business (B2B).
1 Scope
This document is applicable to all construction products and services related to buildings and
construction works. It specifies and describes the communication format for the information defined in
EN 15804 for business-to-business communication to ensure a common understanding through
consistent communication of information.
NOTE This document does not deal with business-to-consumer communication and is not intended for that
purpose. Business-to-consumer communication format is planned to be the subject of a future document.

5 Communication principles
5.1 General principles
The ITM presents and allows transfer of environmental information. It
— does not preclude the fact that an EPD can have an individual and unique format;
— is the standardized part of EPD communication according to EN 15804;
— shall contain a statement whether the ITM has been independently verified.
5.2 Types of information addressed
Table 1 describes how ITM addresses the different types of information according to EN 15804.

6 Requirements for EPD communication format
An EPD shall include an ITM following these formatting requirements (electronic and paper):
— the information in the ITM shall not be misleading;
— as regards the structure of the EPD, information shall be accurately placed in its unique position
identified in the ITM, according to Annex A, but tables can be transposed from rows to columns and
vice versa;
— quantitative data shall be numerically reported in the appropriate units of measurement as
prescribed in EN 15804;
— no more than three significant figures shall be applied to numerical reporting;
— text shall be clearly written adopting a single language throughout;
— where text is conveying a qualitative issue or parameter, it shall provide sufficient detail as to give
transparency and precise and accurate understanding of that issue or parameter.
