A KOMIR-included Carbon Emissions DB Based on the Standard Quantity per Unit in Mine Rehabilitation Projects for use in the design of "Mine Rehabilitation Projects as carbon neutral C codes" in the "GuidebooK: Mine Rehabilitation Technology in Korea -2022 Edition Appendix." In this study, a method of utilizing the "Mine Rehabilitation Projects as carbon neutral C codes" was proposed and the applicability of carbon emissions to eight "Mine Rehabilitation Projects" was reviewed through case studies.
