USG Corp. has expanded the Environmental Responsibility section of its Web site with new information on the subject. The expanded section includes a Product Sustainability Table covering a wide range of products manufactured by USG Co. and USG Interiors. The table features specifications on post-consumer and post-industrial recycled content, densities, volatile organic compounds, manufacturing efficiencies and raw materials for each product, plus other details.

In addition, the company has developed specific answers to the ASTM E2129 "Standard Practice for Data Collection for Sustainability Assessment of Building Products" as applied to products, manufacturing processes, operational performance, indoor environmental quality and corporate environmental policies. This ASTM standard is frequently used as a guideline in answering industry questions about sustainable construction.
