Greenhouse gas (GHG) emissions from onsite equipment usage have not been fully investigated despite their high reduction potential. This study presents a comparative analysis of the generation of GHGs by various equipment types used in different construction activities. Twenty-four cases involving a typical road construction project in Korea were selected for comparison. GHG emissions from onsite equipment usage for different activities were estimated using final design documents, which fully defined the construction project. This study also provides the expected ranges of such emissions according to equipment productivity related to site conditions of good, fair, and poor. For the major activities that produced most of the GHG emissions from onsite equipment, the value was estimated to be in the range of 256.52-376.70 tCO2e, with 282.17 tCO2e for fair site conditions. A focus group interview (FGI) was conducted to identify guidelines that can be applied to improve equipment productivity to reduce GHG emissions. The proper selection of equipment and its components to deal with specific site conditions was one of the fundamental reduction methods derived through the FGI. These study results can be used to reduce GHG emissions from onsite equipment usage
