Israel Waichman, Professor of Economics, publishes research in the Nature Portfolio Journal: Climate Action

Professor of Economics Israel Waichman co-authored a review article titled “Supply-chain data sharing for scope 3 emissions” with Aurel Stenzel (University of Kiel; co-chairman of the SINE foundation) in Nature Portfolio Journal: Climate Action. The article covers the obstacles to and the benefits from firms sharing data with each other about their actual greenhouse gas emissions, with the ultimate goal of reducing overall greenhouse gas emissions.

The article focuses on the measurement of Scope 3 emissions, which are indirect emissions produced along a firm’s supply chain, and “represent the majority of most firms’ carbon footprint in the production process.” While firms are already required to report direct emissions data, Stenzel and Waichman’s research focuses on “primary data sharing along the supply chain [which] would provide firms with precise measures of Scope 3 emissions that are eventually necessary for decarbonizing supply chain emissions beyond industry averages.” The “overarching motivation in sharing primary data for Scope 3 emissions is to optimally mitigate GHG emissions.” To facilities such primary data sharing, there is a need to address “legal and regulatory challenges, missing interoperability, and data privacy concerns.” The article concludes with a discussion of initiatives and approaches for overcoming these obstacles, and further benefits firms may discover through primary data sharing, such as “new business models within digitized supply chains.”
