ACLCA PCR Open Standard

Ensuring transparency and reliability in procurement and supply chain data.

The ACLCA PCR Open Standard is the authoritative framework for developing high-quality Product Category Rules (PCRs)  ensuring consistency and reliability in PCRs and Environmental Product Declarations (EPDs), which are critical tools for assessing and communicating environmental impacts of products and processes.

The ACLCA PCR Open Standard provides process checklists for each of the key roles in the product category rule creation process and methods and methodologies addenda on areas related to PCR development.

ACLCA PCR Open Standard V2.0

The Standards Behind the Standards
‍
ACLCA PCR Open Standard V2.0 and other standards to support a more robust EPD ecosystem 
‍The backbone of credible EPDs and transparent data in procurement and design.
Version 2.0 is advancing international interoperability and setting the new benchmark for consistency, comparability, and confidence in product environmental information.
‍
Version 2.0—and the full suite of standards envisioned—will drive alignment across industries and government to meet the growing demand for credible, comparable environmental data, while building on Version 1 through additional standards to support product environmental information disclosure across all sectors.
‍
Version 2.0 Standards in Development
‍Version 2.0 work will initially concentrate on several priority focus areas:
•Terminology 
•General Program Instructions
•PCR Requirements
•LCA Requirements for the PCR
‍
These standards will be advanced through targeted Working Groups responsible for drafting documents under the Version 2.0 Committee.
‍
Who's Involved
‍This update is being developed through a multi-stakeholder committee of recognized thought leaders from:
Industry and manufacturing
Government and policy organizations
LCA program operators
Academia and technical experts

PCR Open Standard Methods and Methodologies Addenda
The following PCR Open Standard Addenda have been developed to further aid in harmonizing PCRs and EPDs.
Published
Quantifying Renewable Electricity Instruments in Environmental Product Declarations
The addendum provides a methodology for including and allocating renewable electricity instruments (e.g. RECs, PPAs) in LCA and EPDs, detailing modeling, reporting, and verification requirements. It is the first consensus-based approach for integrating renewable energy into EPDs in North America.
Assessing Data Quality of Background Life Cycle Inventory Datasets
The addendum strengthens standards for Life Cycle Inventory data, ensuring consistent data quality. It addresses discrepancies in LCA outcomes caused by varying background data, enhancing EPD comparability. Standards for using the Enhanced Pedigree Matrix are also provided.
Determining EPD Types and Calculating and Communicating Data Specificity Through the Supply Chain
Provides much-needed standardized nomenclature for types of EPDs covered under the scope of ISO 21930 (e.g. product-specific, facility-specific). Outlines methods to improve the transparency of data in EPDs. Prescribes a methodology for calculating the supply chain specificity of an EPD. Prescribe EPD labeling requirements for EPD programs following this guidance. Recommends language for policymakers on specifying the types of EPDs they will accept.
Allocating Burdens and Benefits of Materials Shared Across Product Systems
The addendum standardizes allocation for materials crossing product system boundaries, reducing subjective variance and preventing double counting of environmental burdens. A harmonized approach enhances EPD comparability, value chain consistency, and avoids miscounted impacts.

Under Development
The PCR committee has multiple addenda in development to further aid in harmonizing PCRs and EPDs.
Under development
Mass Balance Chain of Custody
The addendum provides guidance for LCA practitioners, policymakers, standards setters, and other stakeholders on how to approach LCA for product systems using Mass Balance.
Under development
Developing PCR-specific Digital EPD Reporting Requirements
This addendum standardizes EPD terminology under ISO 21930, enhances data transparency, establishes supply chain specificity calculation methods, prescribes labeling requirements, and provides guidance for policymakers on acceptable EPD types—ultimately improving consistency and usability across the construction sector.
Get Involved
There are multiple ways to get involved in the progression of the PCR Open Standard addenda that are undergoing the developmental process as well as getting involved with ACLCA.
Call for Participation
Assessing Data Quality of Background Life Cycle Inventory Datasets
The Assessing Data Quality of Background Life Cycle Inventory Dataset addenda is undergoing a review and potential revision period. This addendum strengthens the standard for usage of Life Cycle Inventory data. Using different background data can lead to drastically different outcomes making EPDs for similar PCRs incomparable. Even with the same foreground data, a choice of different background inventories can create significant differences in the final LCA results.
