Eco Textiles, a textile manufacturing company, is committed to enhancing its environmental stewardship and aims to integrate Life Cycle Assessment (LCA) into its strategic decision-making processes, aligning with ISO 14044:2006 standards. As the newly appointed sustainability manager, Aaliyah is tasked with defining the functional unit for an LCA study comparing the environmental impacts of conventionally produced cotton fabric versus organically produced hemp fabric intended for use in apparel. The study aims to inform decisions about sourcing materials and optimizing production processes. The CEO, Mr. Ramirez, emphasizes the need for a functional unit that provides a clear and measurable basis for comparing the two fabric options, considering factors such as durability, water resistance, and overall lifespan of the apparel made from these fabrics. Furthermore, the company wants to ensure that the LCA results are robust and can be used to support environmental claims and marketing initiatives. Considering the requirements of ISO 14044:2006 and the specific goals of Eco Textiles, which of the following functional units is the MOST appropriate for Aaliyah to define for this LCA study?
