With the increasing importance of green building certification systems like LEED, having independent verification for building materials is critical.
By 2021, the standard had been widely recognized for several years, and a major related standard—the edition—was in effect. This period saw the standard’s principles being integrated into major green building rating systems. For instance, NSF-certified sustainable products are known to earn points toward the U.S. Green Building Council’s LEED certification, adding tangible value to sustainable projects. The evolution from the original 2012 version to the 2018 version represents a maturation of the sustainability assessment process, incorporating more stringent criteria and broader industry feedback.
: Social responsibility and sustainability reporting from the manufacturer. Innovation nsfs 347 2021
True sustainability extends to social responsibility and corporate accountability. This section evaluates the manufacturer's corporate ecosystem: Duro-Last® and NSF/ANSI 347
The NSF/ANSI 347 Sustainability Assessment solves this issue. It applies comprehensive Life Cycle Assessment (LCA) principles to analyze products from initial raw material extraction through manufacturing, field usage, and eventual end-of-life management. The standard applies to all major single-ply formulations, including: (Thermoplastic Polyolefin) PVC (Polyvinyl Chloride) EPDM (Ethylene Propylene Diene Terpolymer) KEE (Ketone Ethylene Ester) PIB (Polyisobutylene)

While the foundational standard was established earlier, periodic updates (such as those in 2021) ensure the criteria align with current science, technologies, and evolving market expectations for sustainable building materials. Key Pillars of the NSF/ANSI 347-2021 Standard
The standard was developed by the and published in 2021 .
Encourages manufacturers to integrate environmental thinking at the earliest stages of development, often called "enlightened design".
Manufacturers achieve certification based on their total point score: Minimum 35 points Silver: Minimum 45 points Gold: Minimum 56 points Platinum: Minimum 75 points | With the increasing importance of green building
Unlike single-attribute certifications that only focus on recycled content or reflectivity, NSF/ANSI 347 utilizes a comprehensive approach. It tracks a roofing membrane's environmental footprint from raw material extraction, through manufacturing and decades of building performance, to its eventual disposal or reclamation.
NSFS 347 2021 is a critical standard that outlines the requirements for food safety management in Australia. By understanding and complying with the standard, food businesses can reduce the risk of foodborne illness, improve their brand reputation, and ensure compliance with regulatory requirements. By following best practices and continuously improving their food safety management system, businesses can ensure the highest level of food safety and protect their customers.

Developed through NSF International , in collaboration with industry stakeholders, the NSF/ANSI 347 standard is designed to assess the sustainability profile of single-ply membranes. These include (Ethylene Propylene Diene Terpolymer), PVC (Polyvinyl Chloride), TPO (Thermoplastic Polyolefin), KEE (Ketone Ethylene Ester), and PIB (Polyisobutylene).
