NSC Sustainability Benchmark Survey: Results and Publications
A number of reports and other informative material will be made available as this project continues. This page provides these documents, specifically:

Life-cycle inventories have been established for granite, limestone, sandstone, and slate quarrying and processing operations. These data will serve a multitude of functions, including the ability to:
- Characterize the environmental profile of natural stone industry operations by providing an estimate of embodied energy, water consumption, and material resource utilization per ft3 of stone extracted and produced;
- Identify improvement areas for industry operations;
- Assist in establishing best practices of industry operations against which improvement can be measured; and
- Feed material fact sheets and other documents useful for the stone and design communities.
These reports are provided below Note that these documents are updates to earlier versions (v1) posted in August 2008. Changes from v1 are detailed in each report.
The LCI datasets have been instrumental in illuminating the industry’s improvement areas. In order to communicate these focus points and to provide direction in modifying quarry and processing operations, a series of best practice documents is being generated.
- Best Practice: Water Consumption, Treatment, and Reuse
- Best Practice: Site Maintenance and Quarry Closure
- Best Practice: Solid Waste Management
- Best Practice: Transportation
Using stone products in building applications can produce certain environmental benefits. Real examples are highlighted through case studies to communicate these positive aspects of stone.
- Case Study: Application of Green Building Certification Programs to Natural Stone
- Case Study: Durability of Stone Flooring in High Traffic Areas
- Case Study: Use of Reclaimed Stone in Building Construction
- Case Study: Solar Reflectance of Natural Stone
Designers, architects, and sometimes even researchers, among other audiences, find utility in reference materials that provide a quick overview of a particular topic. Material fact sheets describing specific stone types have been developed to meet this need. The one-page (double-sided) documents are partially fed by the life-cycle inventories and inform the reader about the stone’s natural formation, region(s) of deposits worldwide, physical properties, applicable ASTM standards, as well as environmental and human health considerations.
- Material Fact Sheet: Granite
- Material Fact Sheet: Limestone
- Material Fact Sheet: Marble
- Material Fact Sheet: Sandstone
- Material Fact Sheet: Slate
Life-cycle assessment (LCA) is a holistic evaluation of a product’s environmental footprint and can be employed to compare alternative materials’ sustainability profiles. With the data collected by earlier phases of the UT-NSC collaboration, an LCA has been performed to identify the benefits and trade-offs of granite and limestone to some of their competitors, namely aluminum composite panels, brick and mortar, and precast concrete. While the results of the study are indeed informative, it is important to remember that conclusions are valid only within the context of the investigation. The report is provided below.
