This achievement will help further motivate UMC's sustainability efforts, as the milestone comes less than one month after UMC received CommonWealth magazine's Global Citizenship Award. The hard work shown by our employees has not only resulted in UMC's repeated selection as a DJSI index component, but also improved overall scores in recent years. Going forward, UMC will continue to strive for excellence by working closely with employees, customers and supply chain partners to drive towards our goal of a sustainable society."
