Abstract

Global warning and climate change adaptation policies have become a major issue for all nations. To establish and implement a GHG (Greenhouse gas) reduction plan in the construction sector, we need to secure data for actual GHG emissions. However, information on energy consumption and GHG emissions in the construction sector is lacking. The purpose of this study is to calculate 1) GHG emissions generated in the construction sector, 2) the annual variation in emissions, and 3) emission characteristics from emission intensity of the construction sector. This study provides information on the amount of GHG emissions and its characteristics within the construction industry and in the overall view. As a result of GHG emissions calculations from the construction sector, GHG emissions in 2007 were 2.51 million ton CO<SUB>2-eq</SUB>, almost the same as the emission reported by the government. Annual GHG emissions have decreased at a mean rate of (-)1.2% from 2006 until 2019. The calculated emission intensity of the construction sector was about 0.02 ton CO<SUB>2-eq</SUB>/million KRW, showing a continuously decreasing tendency until 2019, at an annual mean rate of (-)0.3%.
