—The method for estimating carbon emissions across road life cycle is applied to G-TIES (green road technology investment evaluation system) being developed in Korea. G-TIES is an evaluation system that supports activities to gauge applicability of green road technology that reduces carbon emissions and to forecast benefits of application. First of all, the authors selected programs assessed to stand out among those already developed and are in use and qualitatively compared their functions in order to evaluate performance of the methodology adopted by G-TIES to calculate carbon emissions. In addition, G-TIES, ROADEO and Carbon Gauge Tool, which can calculate carbon emissions by entering general information on road projects, were used to calculate carbon amount emitted during construction of a road section in Korea. The values gained from ROADEO and Carbon Gauge Tool differed greatly from the value gained from G-TIES. Although further improvements need to be made in G-TIES in ways to include greater parts of carbon emission source in road works and reflect a wide variety of road construction conditions it is deemed to be more appropriate than other tools in calculating carbon emissions in road construction projects in Korea as its development is based on actual road constructions in the country.
