The purpose of green concrete specification is to decrease the negative environmental impacts (such as GHG and waste generation) and increase positive environmental impacts (such as long service life) incorporating lifecycle concept where applicable. The 2013 Building Construction Standard Specification of AIK (Architectural Institute of Korea) has first adopted the concept of "Environmental management and green construction" generally following the principles outlined by ISO 14000 series such as ISO 14001, 14025, and 14040. Korea Concrete Institute (KCI) has further pursued this concept and expanded the contents of "Environmental management and green construction" for concrete in 2016.
