Unilever Pursues Supply Chain Sustainability with Blockchain

# Overview In this interview from TechTarget, Nicole Laskowski, senior news director, speaks with Jim O'Donnell, a reporter covering SAP and ERP sites. The discussion centers on the intersection of enterprise resource planning (ERP), blockchain technology, and sustainability initiatives, spotlighting a solution called GreenToken by SAP and its implementation by consumer goods giant Unilever.

# Key Topics - **GreenToken by SAP**: Originating from SAP's startup incubator, GreenToken is a SaaS offering designed to provide proof of responsible raw material sourcing across supply chains. - **Unilever's Use Case**: Unilever, a large consumer products manufacturer producing goods ranging from soaps to beverages, uses GreenToken to trace raw materials like palm oil. - **Palm Oil Sourcing and Environmental Impact**: Palm oil production has roughly doubled over the past 20 years, predominantly in regions where cultivation can negatively impact rainforests. Buyers require verification that palm oil is harvested responsibly from certified plantations. - **ERP Systems and Sustainability**: ERP platforms function as the core data backbone for enterprises, gathering operational, manufacturing, logistics, and transportation information necessary for environmental accountability and carbon tracking.

# Technical Details - **Blockchain-Based Provenance**: GreenToken utilizes a blockchain where producers enter data regarding raw materials, geographical origin, and certification records from sustainability NGOs. - **Immutability and Traceability**: The recorded sustainability data follows the product through every stage of the supply chain, ensuring that the raw material is verified as coming from responsible sources and has not been altered or tampered with in transit. - **Platform Architecture**: GreenToken operates independently as a SaaS product and is not strictly tied to SAP core ERP systems, though it complements broader ERP infrastructure. - **Enterprise Data Aggregation**: ERP systems act as the central nervous system of large organizations, centralizing supply chain, manufacturing, and logistics data. This enables enterprises to track environmental metrics, such as carbon emissions generated during transportation and worldwide movement of goods.

# Takeaways - Blockchain provides a mechanism to establish chain-of-custody verification and prevent unauthorized alteration of sourcing certifications. - Companies like Unilever leverage this traceability to ensure commodities like palm oil do not drive deforestation and are harvested responsibly. - ERP vendors are focusing heavily on sustainability initiatives because their systems already aggregate the logistical and operational data required to audit supply chains and measure environmental footprints.
