Major developed countries have been trying to build a block of the global semiconductor industry supply chain by considering their interests first. And their supply chain due diligence agreement demands the due diligence on environmental risks that may occur throughout the supply chain. So the integrated approach called supply chain ESG is needed. But there is not yet to be a global standard for ESG, and the disclosure standards for each country are different, adding to companies’ confusion. So this study shows environmental evaluation indicators of global semiconductor supply chain ESG customized for Korean SMEs and then performs weight analysis using AHP methodology. Through this, this study aims to suggest implications for gaining sustainability within the supply chain of Korean SMEs by presenting indicators to be considered first among environmental evaluation indicators in preparation for ESG due diligence of the global semiconductor supply chain.
