NSF/ANSI 347 (published 2021) is a voluntary sustainability standard and third‑party certification protocol for single‑ply roofing membranes. It sets criteria across material health, product efficiency, manufacturing, supply chain transparency, and end‑of‑life to help roof membrane manufacturers demonstrate reduced environmental and social impacts and support sustainable building rating systems.

This category rewards manufacturers who introduce forward-thinking technologies or processes that exceed the baseline requirements of the standard. Examples include pioneering advanced closed-loop roof recycling programs or engineering breakthrough material configurations that drastically reduce carbon footprints.

The construction industry has long been a significant contributor to global carbon emissions and waste. As building owners and architects shift toward "green" building practices, the need for standardized, third-party verification of "sustainable" materials has become paramount. stands as the premier consensus-based standard specifically designed to evaluate the environmental footprint of single-ply roofing membranes, such as PVC, TPO, and EPDM.
