Which standard includes sustainability principles in building construction that relate to EPDs?

The correct choice is based on the focus of ISO 21930, which specifically addresses the environmental product declarations (EPDs) as they pertain to building and construction products. This standard is designed to provide principles and requirements for EPDs in the context of sustainable construction, taking into account key sustainability impacts and information for stakeholders.

ISO 21930 emphasizes how EPDs can be utilized to convey the environmental performance of construction products throughout their life cycle. By establishing a consistent methodology for creating EPDs, it helps enhance transparency and comparability among products, thereby promoting sustainability within the industry.

In contrast, other options touch on different aspects of environmental standards. For example, ISO 14021 deals with self-declared environmental claims (Type II environmental labels) but doesn't specifically focus on EPDs. ISO 14040 addresses the principles and framework for life cycle assessment (LCA), providing a methodology but not the specific guidelines for EPDs in building construction. Meanwhile, ISO 14062 is concerned with integrating environmental aspects into product design and development processes, which indirectly relates to sustainability but does not center on EPDs. Each of these other standards has its own merit, yet they do not specifically target the principles surrounding EPDs in
