Build greater environmental transparency into your product sector and earn the respect of your stakeholders and customers by establishing carefully crafted Product Category Rules (PCRs). PCRs are the product category-specific requirements for conducting life cycle assessment (LCA) studies and reporting their findings through Environmental Product Declarations (EPD), consistent with international standards ISO 14025 and ISO 14044. EPDs are recognized by a growing number of green rating systems, such as LEED v4 and Green Globes.
PCR Sponsorship
Product Category Rule (PCR) development is typically sponsored by a group of stakeholders, including industry associations, groups of manufacturers, or other interested parties. Individual manufacturers may contact SCS for PCR development services, but the process must include a stakeholder group involving multiple parties.
Relevant Standards
PCRs must be prepared in accordance with the requirements set forth in ISO 14025. PCRs of construction products must additionally comply with ISO 21930. Copies of these ISO standards can be downloaded from ANSI: http://www.webstore.ansi.org.
SCS' Role
Our job is guide your PCR development process to assure that it fully complies with the requirements of international standards, and that it achieves the transparency, scientific grounding, and comprehensive coverage needed to guarantee credibility in the marketplace. We will assist with organization of the stakeholder group, manage the peer review process, provide expert input based on extensive experience with LCA, and oversee the PCR development.

Ask us for additional support in the following areas:
The PCR development process involves a series of discrete steps:
Review existing applicable Product Category Rules, if any
Discuss scope of product category to be covered and the LCA framework
Assemble a group of stakeholders
Start work with a PCR template provided by SCS
Convene stakeholder group to draft the PCR
Review public comments and revise the draft PCR
Send revised draft to a qualified peer review panel
Make further revisions, then return to panel for final peer review
Post the draft PCR for public comment
Publish the final PCR
What is the purpose of a Product Category Rule (PCR)?
PCRs are intended to level the playing field when comparing the life cycle assessment (LCA) results or Environmental Product Declarations (EPDs) of similar products. Specifically, their purpose is to provide a consistent set of rules and ensure that the LCA adequately addresses issues relevant to a particular product category.
What is driving the development of PCRs?
Stakeholders are now demanding more transparency and disclosure of the impacts for products. Green rating systems such as LEED v4 and Green Globes now give credit to products for which EPDs have been prepared.
Who are the stakeholders in a PCR development process?
The stakeholders for any given PCR may include material suppliers, manufacturers, purchasers, users, non-governmental organizations (NGOs), academics and scientists, public agencies, LCA Practitioners, and certification bodies.
Who can peer review a PCR?
The peer review team consists of individuals with sufficient knowledge of life cycle assessment, the relevant ISO standards, and the product category to be able to fairly critique the work and lend credibility to the process. The peer review panel will consist of a minimum of 3 individuals.
What is the connection between PCRs and international standards?
PCRs are described in ISO 14025, the international standard for Environmental Product Declarations (EPDs). That standard, in turn, refers back to ISO 14044, the standard for life cycle assessment (LCA). (PCRs of construction products must additionally comply with ISO 21930.) As these standards are updated through the normal ISO process, it will be important to assure that the PCRs continue to comply with such standards. SCS can help you set your PCR up to comply with the most stringent LCA reforms.
