What is the product value of a product-specific declaration according to EPD types?

1. 1/4 of a product

2. 1/2 of a product

3. 3/4 of a product

4. 1 product

The correct answer is: 1/4 of a product

The product value of a product-specific declaration according to Environmental Product Declarations (EPDs) is understood as a defined portion of the total product life cycle. A product-specific EPD is a type of EPD that provides detailed information about the environmental impact of a specific product, derived from life-cycle assessment results that conform to relevant ISO standards. In this context, EPDs can be categorized into several types, with the product-specific EPD focusing on a single product rather than a whole category. When evaluating the scope of the data provided, a product-specific EPD often accounts for about a quarter of the total life cycle impact due to its narrower focus. This helps designers and builders make informed decisions based on precise environmental impacts associated with that particular product, ensuring that they have clear and actionable information to utilize during the design and construction process. Understanding this context helps in realizing that the other options indicate greater portions of a product's total value, which do not fit the established convention for product-specific declarations in EPDs.
