During Marmomacc, the most important stone show in the world, an equally important event took place. Leaders from many of the world’s stone associations, federations, and publications gathered to meet and discuss the development of a green certification standard for natural stone. Sebastiano Brancoli, representing VeronaFiere, kicked off the meeting, reminding attendees of the continued efforts on this topic which had begun last year. “A standard certification system is needed so that architects understand and trust that it is clean,” he said.

John Mattke, President of Cold Spring Granite, then took the reins to provide a short history of the Natural Stone Council (NSC) and reviewed the goals to educate and inform the industry about the role of the environment in their activities and priorities. “Within 18 to 24 months, there will be a U.S. Green Building Council standard to be adhered to,” he said.

Mattke formally introduced the main speakers and representatives of the NSC, and asked attendees to offer up a short statement of the current efforts and interest in sustainability within their organizations. Most commented that they were focused on a variety of efforts, including a comparative research analysis of stone to materials such as glass; participating in the development and refinement of programs that are similar to LEED such as BREEAM and Green Guide in the U.K.; and the development of Environmental Product Declarations (EPDs), which are underway in Europe. Additionally, general concern for the environment is evident as attendees understand the impact that population growth and the demand for development are having on resources.

Jack Geibig, President of EcoForm, proceeded with an overview of the development of the proposed green certification standard for natural stone. The standard process began in response to the growing green building market and regulatory environment in the U.S. Programs such as the U.S. Green Building Council’s Leadership in Energy and Environmental Design (LEED), Green Globes and others have made it absolutely essential for future market success to have such a label for stone. The certification standard process will be run in accordance with ANSI standards with support and cooperation from the National Sanitation Foundation (NSF). The development of the standard is expected to take between 18 and 20 months and will entail a variety of committee meetings and reviews through a multi-stakeholder process with the intent of developing criteria and performing technical research. Geibig sought the input and interest of the attendees to join the effort and participate in the process. He also clarified for the attendees the difference between such a standard and an EPD, which do not make a value judgment. Other comments raised included the concern over a variety of different programs being developed instead of one coordinated method for creating sustainable buildings and environments. Geibig reminded the attendees that they could all benefit from the development of the standard as it will establish a set of well-defined environmental and human health metrics that are recognized by the green building movement as an indicator of leadership in sustainability performance. The standard also has the potential to harmonize national and international environmental requirements for stone quarrying and production as well as create parity and a competitive edge for the stone industry as a whole.  

“The misinformation out there is countered by data,” Geibig said. “A benchmarking study is being done with 40 granite quarries and 26 processing facilities to determine industry best practices in terms of waste management, transportation, site maintenance and closure and water consumption, treatment and re-use.”

By establishing a public standard, the stone industry can offset the negative publicity campaigns of alternative products. “The best defense is the offense of creating a standard that can be third-party verified, that is transparent and shows that the industry is doing the right things to establish the stone industry as an environmental player,” Geibig said.

Gary Distelhorst, Executive Vice President of the Marble Institute of America (MIA), provided an overview of the financial implications of the stone certification process and formally solicited support for the effort. “Funding has to come from the industry - companies and associations,” he said. “We need the support of stone companies around the world. We need financial resources as well as help in developing standards. We need money to bring it to market - to architects and designers - and we invite the support and involvement of the industry.”

Final discussions centered on coordinating communications and collaborating at an informational and educational level. Sharing of attendee information will be circulated so that the group can continue to discuss, coordinate and participate in the standard process as it moves forward. The joint committee is nearly formed and there will be an initial teleconference, followed up shortly by a face-to-face meeting to begin the standards development process in earnest. For the standard to truly have international recognition and influence, support and input from all the organizations and representatives of natural stone around the world is critical. So it is the intention of the NSC to reach out further to those who did not participate in the meeting while continuing to build on the relationships that have already been established through regular communications and in-person meetings on the subject of stone and sustainability in the coming months.

Sustainability has emerged as the seminal issue of this decade, both in the U.S. and globally. Unstable global energy supplies, international scientific and political debates over climate change and increased emphasis on life cycle-based policy setting have provided the background for the continued and strengthening focus on sustainability within the public discourse. Despite the backdrop of severe economic recession, nowhere has the effect of this been felt more dramatically than in the building sector, as exemplified by the evolution of green building policies and rating programs, and new and emerging green products and continued demand and growth in the number of Leadership in Energy and Environmental Design (LEED)-rated buildings.

The Natural Stone Council (NSC) and its members in the natural stone industry continue to be a part of this effort. Over the last three years, the NSC and the industry have worked to characterize and ultimately improve the overall sustainability of its members’ operations and the products they manufacture. In partnership with the Center for Clean Products at the University of Tennessee, the NSC conducted a comprehensive benchmarking of industry operations, identified and communicated best practices, made industry and product environmental data publicly available and evaluated stone cladding products against alternatives using a life-cycle framework. Through these efforts, the industry has gained valuable understanding about the environmental strengths and liabilities of stone relative to other materials, developed strategic goals for improvement, and gained valuable insight required to effectively position stone in the evolving green building movement.

These essential efforts are the foundation for the next phase of work. Members of the NSC and the dimensional stone industry announced the development and launch of an international certification program for dimensional stone products, which began in September 2010.

Benefits to the stone industry of a stone standard

Building a credible certification program for stone will require both the development of robust standards through American National Standards Institute (ANSI) and the formation of a credible compliance and verification system. When completed, such a system will:
  • Establish a set of well-defined environmental and human health metrics recognized by the green building movement as an indicator of leadership in sustainability performance.

  • Provide an important opportunity to educate key members of the green building movement, government and environmental advocacy groups about the production of stone products.

  • Create a mechanism that rewards natural stone companies that demonstrate environmental leadership through commitment to sustainable operations and continued innovation.

  • Preempt competitor marketing claims by proactively addressing potential stone-related environmental and human health concerns in a multi-stakeholder, science-based forum (i.e. radon, dust, etc.).

  • Harmonize national and international environmental requirements for stone quarrying and production.

  • Create parity and a competitive edge between stone and other competitive products covered by existing certification programs.


How is the stone standard being developed?

The NSC Dimensional Stone standard is being developed through an ANSI-based multi-stakeholder process, with an eye towards development of an International Standards Organization (ISO) compliant standard with an international scope. The development process involves the creation of a core committee tasked with overseeing the development of draft criteria and performing technical research, and a larger group of stakeholders expects to review and ultimately approve individual criteria and the final standard.

Who is developing the ANSI Dimensional Stone standard?

The dimensional stone standard is being developed by Ecoform in partnership with the National Sanitary Foundation (NSF), under funding from the NSC. Ecoform, a group staffed in part by researchers from the University of Tennessee (UT) Center for Clean Products, has extensive experience in developing leading environmental product standards for a wide range of products, including standards for green cleaning chemicals, toys, building products and consumer electronics. NSF is the leading ANSI-accredited development organization in North America. Jack Geibig, President of Ecoform, is leading the development process.

What will fall within the scope of the standard?

The focus of the ANSI standard is on North American-based stone products and operations, but is being developed with the participation and cooperation of the international stone community. When completed, the standard will provide a basis for expansion to a proposed ISO certification. Criteria will address both environmentally preferable products and stone production operations, and it will be applicable to international as well as U.S. stone operations.

When will the standard development process begin, and how long is it expected to take?

Initial planning by UT and NSF has already begun, and a Project Initiation Notice (PIN) - the public notification of an impending ANSI standard development process - has been issued. Development of the standard itself began in October 2010, and it will take approximately 18 to 20 months to complete. A dimensional stone certification program will be launched upon completion, with applications for certification being accepted by the first quarter of 2012.

How can international organizations and companies become involved?

International participants are being sought for both the Core Committee and the broader stakeholder group. Individuals interested in becoming directly involved in the development of criteria are encouraged to submit an application for one of the limited positions on the Core Committee, the body charged with oversight of the development process. In addition, stakeholders are currently being sought from a variety of national and international organizations, including the stone industry, government, environmental advocacy, academia, green building and design and other relevant groups. Stakeholders will have the opportunity to provide comment on review drafts and the final standard.

How will products be certified under the standard?

A certification and compliance protocol, to be developed concurrently with the standard, will govern the certification process. Select independent certifying organizations meeting this protocol will be allowed to certify products under the standard. All products certified under the standard will be tagged with a green label to be developed and branded by the stone industry, similar in nature to other green product labels in the marketplace.

How is the standard being funded?

Initial funding for the development of the standard is being provided by the NSC. Funding is being sought by the NSC from other national and international stone organizations. Total funding for the development of the standard and launch of a certification process is expected to be $400,000.
