ACI has helped lead the concrete industry in a sustainable direction through the formation of ACI Committee 130, Sustainability of Concrete, and cosponsoring the Concrete Sustainability Forum. The latest forum, Concrete Sustainability Forum IV, was held at the ACI Fall 2011 Convention in Cincinnati, OH. Presented topics included ISO TC 71/SC 8 Standard Development, ISO TC 59/SC 17 Standard Development, ACI Committee 130 Work, Incorporating LCA into Codes and Standards, ISI Rating Tools, Low-Carbon Concrete, Sustainable Building, and Essence of Sustainability—Lessons from the Japan Disaster.
