Sustainability is the one metric where both consumers and firms are ‘Supply-Chain-aware’; that is, buying decisions do not depend exclusively on product or financial considerations but also on the sustainability performance of the *entire* supply chain. However, empirical research in supply chain management is, at the moment, behind these developments. The main reason is that supply chain sustainability is hard to measure in an objective way: (1) Data availability is very poor — often relying on self-reporting; (2) if data is available, it’s typically at the firm-level (not SC); (3) furthermore, if data is available it is often not transparent — it usually consists of opaque proprietary data that do not allow for the study of different aspects of sustainability. This project intends to address these issues. We’ll first combine several sources of objective, firm-level, sustainability data with existing supply-chain data to construct a large supply-chain-level sustainability dataset. We will then use this dataset to perform descriptive and prescriptive empirical studies – our main objectives are to show (1) how sustainability in supply chains has evolved during the last decade, and (2) how “sustainable” supply chains differ from “non-sustainable” ones.
