To address calls for streamlining embodied carbon in private and public work, LafargeHolcim plans to issue Environmental Product Declarations (EPD) covering shipments from its U.S. Aggregates and Construction Materials (ACM) and Cement businesses. It will enlist top auditors and EPD Program Operators to prepare, verify and host a library of ready mixed concrete or cement declarations abiding the latest criteria for quantifying carbon dioxide emissions throughout raw material, processing, delivery and finishing phases.

The Carbon Leadership Forum (CLF), a University of Washington College of Built Environments-hosted coalition of architecture, engineering and construction stakeholders, formally launched the Embodied Carbon in Construction Calculator (EC3) tool in public beta version at the U.S. Green Building Council’s Greenbuild International Conference & Expo in Atlanta. Embodied carbon volumes reflect carbon dioxide emissions attributable to material or product processing, fabrication, delivery, and erection or placement.

A global engineer’s seven-year survey of 600-plus buildings assesses materials, structural components and facility types with the highest embodied carbon, and cites a market-driven trend toward increased use of supplementary cementitious materials and recycled steel as the largest driver of a reduction in that metric.
