What quantitative indicators do construction companies use to manage ESG?-A case study in South Korea-

This study aims to identify the quantitative indicators construction companies use for Environmental, Social, and Governance (ESG) and to investigate their trends. ESG implementation in the construction industry is crucial due to its significant impact on the labor market and environment. However, challenges such as high accident rates and substantial industrial waste generation hinder full ESG integration. The diversity of ESG scores and criteria also slows adoption in the industry. To evaluate the current state of ESG management, this study reviewed ESG reports from the past 10 years of nine general contractor companies in South Korea, identifying 28 common quantitative indicators: 10 Environmental, 13 Social, and 5 Governance. Time series analysis revealed an increasing number of companies using these indicators, with progressive improvements in the values of E, S, and G indicators, reflecting better fulfillment of social responsibilities. These findings can aid ESG management, particularly for small and medium-sized companies lacking resources for ESG implementation. Additionally, by presenting trends over time, this study offers guidance on which indicators should be reinforced for improved ESG performance in the construction industry.
