Because of their limited bandwidth, small and medium enterprises (SME’s) sometimes struggle to respond to the environmental and social sustainability expectations set by large customers. Purchasing organizations committed to supplier diversity and local economic development are proactively helping SMEs get ahead of the many sustainability requests and requirements coming from themselves and other customers by supporting the SMEs in developing their capacity to profitably understand and manage the sustainability of their own business. Done right, these engagement efforts can forge deeper supply chain resilience and reliability for the purchaser, also. In this session SPLC will first present its curated set of tools, trainings, programs, and materials that purchasing organizations can use to help suppliers improve their sustainability performance. We will hear from two recent experiences of running supplier development programs on sustainability, PG&E’s “Diverse Suppliers Go Green” program and training, and The State of Minnesota’s targeted vendor engagement on sustainability.
