Sustainability management and reporting, understood as the processes by which companies identify, measure, monitor, and disclose their material environmental, social, and governance risks, opportunities, and impacts, has become increasingly essential to how businesses build competitiveness, resilience, and trust in today’s economy. At the same time, sustainability management and reporting are a critical foundation for system-level impact transparency, particularly when adopted consistently across value chains. Yet for most small and medium enterprises (SMEs)—especially in emerging markets and developing economies (EMDEs)—the business case remains unclear, and the pathway to implementation often feels out of reach. Limited resources, capacity and technical know-how, combined with emerging sustainability-related reporting requirements designed primarily for large corporations, make it difficult for SMEs to engage meaningfully.
