Product Category Rules

Information used in an EPD is based on an life-cycle assessment (LCA) methodology following certain product-specific requirements and boundaries, referred to as Product Category Rules (PCRs). These are the rules a product must follow to develop and publish and EPD in order to create a fair, credible report.

 

NAPA and a group of industry experts developed a North American PCR for asphalt mixtures. Members of the public submitted comments on the PCR during the public review period.
