Developed for PCR Committees and LCA practitioners, the report addresses a critical gap in current practice: the lack of consistent guidance for characterizing and communicating uncertainty in the data underlying EPD results. \u003cspan class=\"contents\"\u003e\u003c\/span\u003e\u003c\/p\u003e\n\u003cp\u003eThe guidance provides approaches for establishing data-source hierarchies, determining ranges and thresholds for background and foreground data, conducting sensitivity and data-quality assessments, and communicating uncertainty in EPDs. It uses Global Warming Potential (GWP) as the primary example while providing a framework that can also be applied to other environmental impact indicators. \u003cspan class=\"contents\"\u003e\u003c\/span\u003e\u003c\/p\u003e\n\u003cp\u003eDesigned to support more robust, transparent, and decision-useful environmental information, the report includes practical methodologies, decision frameworks, worked examples, and recommendations for incorporating uncertainty into PCR development and EPD reporting. \u003cspan class=\"contents\"\u003e\u003c\/span\u003e\u003c\/p\u003e\n\u003cp\u003ePublished by the American Center for Life Cycle Assessment (ACLCA), 2026.\u003c\/p\u003e","brand":"ACLCA","offers":[{"title":"Default Title","offer_id":44271126020183,"sku":null,"price":0.0,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0202\/5897\/9904\/files\/ACLCA_Uncertainty_PCR_EPD_Shopify_Cover.png?v=1789209196","url":"https:\/\/lcacenter.org\/products\/uncertainty-management-in-product-category-rule-pcr-development-and-reporting-in-environmental-product-declarations-epds","provider":"ACLCA","version":"1.0","type":"link"}
