The supply chain represents a business's operational backbone, and for small and medium-sized enterprises, it carries substantial weight in determining their overall environmental, social, and governance footprint. Research indicates that companies implementing sustainable supply chains can reduce their greenhouse gas emissions by an average of 50%.
Notably, supply chain emissions dwarf operational emissions by a factor of 26, yet businesses typically concentrate their reduction efforts on operational improvements. The COVID-19 pandemic has accelerated digital transformation within SMBs, introducing new technologies that simultaneously improve efficiency and enable sustainable practices.

How can technology support sustainability? AI, IoT, and blockchain improve decision-making, transparency, and traceability while facilitating data collection and operational efficiencies.
