b) Describe which life cycle phases are considered in a particular EPD, which processes are included in the life cycle phases, and the How it is subdivided into information modules;

c) establish rules for how to build scenarios;

d) Rules for reporting relevant environmental and technical information not included in the LCA;

e) specify the core elements to be covered by the EPD;

f) Establishing the structure of project reports;

g) specify the conditions for comparing different building products based on the information provided in the EPD;

h) provide requirements and guidance for PCR of construction product subcategories;

i) Mandatory and non-changeable requirements to be included in any PCR based on this document.

This document applies to exchanges between suppliers and buyers (B2B), but under certain conditions it can also be applied to exchanges between suppliers and consumers (B2C).
