A Study on QA/QC Method for GHG Inventory in the Railroad Construction Sector

철도건설현장의 온실가스 인벤토리 QA/QC 방안 연구

The impact of greenhouse gas (GHG) emissions is the global issue over the world. Korean government has presented various policies to induce GHG reduction for the industries with high energy consumption such as power generation and chemistry. Construction sector has produced a large amount of GHG emissions resulted in the energy consumption of heavy equipments and the use of materials. This study aims to suggest the QA (Quality Assurance) and QC (Quality Control) method to identify and quantify the GHG emissions released from heavy equipments in the railroad construction sector. Generally, the accuracy and reliability of GHG inventory is dependent on the data collection. Therefore, it is necessary to mange the detailed statements for the fuel consumption of heavy equipments and the quantity of work in the field. Also, the breakdown of GHG emission sources should be recorded from the design step of railroad infrastructures. Based on these data, the GHG reduction technologies and polices can be applied in railroad construction sector.
