Product carbon footprint developments and gaps

Purpose – Over the last decade, multiple initiatives have been undertaken to learn how to capture the carbon footprint of a supply chain at a product level. The purpose of this paper is to focus on the process of standardization to secure consistency of product carbon footprinting (PCF) and to outline how the current developments in PCF support the need for a standardized method to measure and report environmental performance in supply chains. Design/methodology/approach – This paper is based on a literature review and a review of international standards for PCF which brings knowledge of PCF to the existing literature of green supply chain management. Findings – The multiple initiatives for standardization each improve the understanding of standardized methods of conducting PCF. At the same time, however, important differences exist between the standards in terms of the modelling framework to be used when conducting a PCF, and a paradox exists concerning methods for securing future standardization of PCF....
