The document discusses green supply chain management (GSCM), which aims to reduce a company's carbon footprint through aligning sourcing, manufacturing, distribution, transportation, and recycling processes. GSCM provides financial benefits like increased revenue and reduced costs. Environmental benefits include reduced emissions, waste, and fuel consumption. Social benefits involve optimizing warehouse space, transportation routes, and logistics networks. However, barriers to implementing GSCM include adapting to customer and supplier changes, the costs of changing processes, and difficulties measuring return on investment.
