Greenhouse gas emissions from onsite equipment usage in road construction

Kim, B; Lee, H; Park, H and Kim, H (2012) Greenhouse gas emissions from onsite equipment usage in road construction. Journal of Construction Engineering and Management, 138(8), pp. 982-990. ISSN 0733-9364

Abstract

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

Descriptive scope: 4 PCEA

N.B. Descriptive scope is a count of how many of the five facets of empirical research are indicated by the words used in title, abstract and keywords. It is not intended as a judgement on the research; merely a count of the kind of word we would expect to indicate Phenomenon, Concepts, Theoretical framing, Empirical techniques, Analytical techniques. If all five are present, then a code of “5 PCTEA” will indicate this. If you feel the coding for this record is questionable, we welcome discussion around the terms we matched or the way we categorized them. The facet you would expect may not be coded, or a facet may be coded inappropriately. This can also bear on a larger question, of which facets should be treated as defining in construction management research. Please get in touch, and we will look at it. More details here
