An environmental product declaration (EPD) for LEED must conform to which of the following standards?

An environmental product declaration (EPD) for LEED must conform to ISO standards, specifically ISO 14025, which provides guidelines for the development of Type III environmental declarations. This standard outlines the requirements for the creation of EPDs, ensuring that they are based on life cycle assessment (LCA) and contain verifiable information about the environmental impacts of products. By adhering to ISO standards, EPDs can provide credible and comparable information that supports transparency and informed decision-making in sustainable design and construction practices.

While the other mentioned organizations and standards play important roles in various aspects of construction and sustainability, they do not specifically provide the framework for EPDs required by LEED. ANSI focuses on the development of consensus standards, LEED-NC pertains to the overall LEED rating system for new construction, and ASTM develops technical standards for materials and products but does not explicitly govern the requirements for EPDs in the context of LEED.
