Concrete Product Category Rule
Establishing the standard to calculate EPDs (reporting the environmental impact of concrete)
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 of 2013. This PCR has been used to develop the Environmental Product Declarations for both individual concrete suppliers and industry average data for both the United States and Canada. Information on published EPDs can be found at the National Ready Mixed Concrete Association’s EPD Website. Current EPD Documents can be downloaded here:
The PCR is due for revision in November of 2017. A technical committee has been formed to review the current PCR and develop recommendations to improve it’s quality and work towards greater alignment with other PCRs in the building industry (both locally and globally). As the Carbon Leadership Forum is no longer acting as an official ‘program operator’, the updated PCR will be verified and reviewed by another program operator prior to publishing later this year.
The NRMCA has funded the technical review oversight. The volunteer technical committees efforts are greatly appreciated and includes representation from Manufacturers (Bill Larson/Dave McElvain-CalPortland, Patrick Frawley-Central Concrete/US Concrete, Jim Blais-Stoneway Concrete/GMC Inc., Kyle Gilmour-Lehigh Cement Vancouver, Manuela Ojan-Heidelberg Cement/WBCSD CSI observer); Trade Organizations (David Shepherd-Portland Cement Association, James Bogdan-NRMCA, Emily Lorenz-Precast/Prestressed Concrete Association), Users (Chris Drew- Adrian Smith Gordon Gill (architect), David Walsh-Sellen Construction (general contractor), Dirk Kestner-Walter P Moore (structural engineer), Erin McDade-Architecture 2030 (NGO), Jordan Palmeri-Oregon Department of Environmental Quality (Gov’t) and LCA Expertise (Jamie Meil-Athena Institute, Laurel McEwen-Climate Earth, Jessica Slomka-NSF)
