The Carbon Leadership Forum has just announced the release of a U.S. specific standard to track and report the environmental footprint of concrete — Concrete Product Category Rules (PCRs).
In 2009, a group of researchers, associations and companies within the building industry came together to respond to this desire for accurate information and disclosure. The group — named the Carbon Leadership Forum (CLF), hosted by the University of Washington, set two key goals:
1. Bring methods and data of Life Cycle Assessment (LCA) to design and construction practice
2. Devise standards that will account for and report carbon footprints of building products and systems.
PCRs enable the creation of standardized Environmental Product Declarations (EPDs), viewed worldwide as the key to providing clear, scientifically based environmental impact data that allows for apple-to-apple comparisons, promotes transparency and instills trust. This has been further supported by Architecture 2030 which has issued the 2030 Challenge for Products recognizing the value of PCRs and EPDs to motivate improved performance of building products.
Culminating over a year of committee effort, two rounds of stakeholder comments and ISO third party verification, this PCR enables ready mixed suppliers, such as Central Concrete, to track and report the impacts of their different concrete mixes and structural engineers, such as Arup and Degenkolb, to include environmental performance in their design specifications. Arup, Central, Degenkolb and the National Ready Mixed Concrete Association have all adopted the Architecture 2030 Challenge for Products.
More on this initiative is available on the CLF website. CLF director Kathrina Simonen will also be at GreenBuild later this week ad can be reached at 415 641 1421 or call Anne Banta (firstname.lastname@example.org, 650-400-9673) to arrange an interview.
