Carbon Leadership Forum

Concrete Product Category Rule

Purpose

To establish the standard to calculate concrete EPDs (reporting the environmental impacts of concrete).

Summary

The Carbon Leadership Forum developed and verified the first version of the North American Product Category Rule (PCR) for Concrete in 2012 and published Version 1.1 in February 2013. This PCR has been used to develop Environmental Product Declarations (EPDs) for individual concrete suppliers and industry average data for the United States and Canada.

Due for revision in November 2017, the PCR was reviewed by a technical committee who worked together to develop recommendations to improve Version 1.1 and drive greater alignment with other PCRs in the building industry (locally and globally).

Results

In February 2019, Version 2.0 was finalized and published on the National Science Foundation (NSF) website.
