NSF publishes Concrete Product Category Rule (PCR) Version 2.0, supported by the CLF

On Feb. 22, 2019, the National Science Foundation (NSF) issued Version 2.0 of the Concrete Product Category Rule (PCR), updating Version 1.1 published by the Carbon Leadership Forum (CLF) in 2013.
CLF Director Kate Simonen supported the review process through providing life cycle assessment (LCA) expertise in her role on the PCR Committee for Concrete. The technical committee included subject matter experts across the building industry who developed recommendations to improve Version 1.1 and drive greater alignment with other PCRs in the building industry (locally and globally).
