MIT CSHub spells carbon uptake accounting method

A new report from the Concrete Sustainability Hub at Massachusetts Institute of Technology, Cambridge, probes statistical and scientific methods for measuring carbon dioxide uptake in hardened concrete and other cement-based products (CBP). It proposes a framework to account for carbon uptake in Product Category Rules (PCRs), documents key to creating verifiable environmental product declarations (EPDs). Credible uptake calculations will contribute…

Life Cycle Factors Gain in ISO 14001:2015

A new version of a global standard behind 300,000 certifications annually, including parties developing Product Category Rules (PCR) and Environmental Product Declarations (EPD) backing green building rating measures, places increased emphasis on life-cycle thinking, considering each stage of a product or service, cradle to grave. Released last month from Geneva-based International Organization for Standardization, ISO 14001:2015 Environmental Management Systems likewise addresses users’ recognition of the need to factor both external and internal elements that influence their impact, including climate volatility, plus proactive initiatives for greater environmental protection.

Construction life cycle assessment pioneer retools Pavement software

Sources: Athena Sustainable Materials Institute, Ottawa; CP staff

The developer of a life cycle assessment (LCA) tool informing ready mixed and manufactured-concrete interests’ product category rules (PCR) and environmental product declarations (EPD) has released Pavement LCA Version 2.1, succeeding the Impact Estimator for Highways software. Athena Institute envisioned the charter program for major freeway and arterial roadway assessment, but notes the tool can now gauge the environmental footprint of any roadway cross-section along its length and over its service life.
