When comparing Environmental Product Declarations (EPDs), what is often noted?

When assessing Environmental Product Declarations (EPDs), it's essential to understand that they provide standardized information about the environmental impact of products. For comparisons to be meaningful, the products being evaluated must have similar functions, applications, and performance characteristics, as EPDs address specific environmental metrics relevant to each product. This alignment ensures that the differences in environmental impacts highlighted in the EPDs are due to genuine variations in the products rather than differences in their intended use or functionalities.

When products are dissimilar, even small differences in one product's EPD may not accurately reflect its environmental performance relative to another. Thus, requiring similar products for accurate comparisons is crucial for obtaining valid and actionable insights from EPDs, thereby supporting informed decision-making in sustainable purchasing practices.
