Abstract
We estimated CO2 emission caused by port construction based on accounts of all port constructions that Ministry of Land, Infrastructure, Transport and Tourism ran in 2010. Port projects were categorized by structure type, and total construction costs of port project were summed up by structure type. We set unit structures for calculation defined by cross-section view and span, and calculated CO2 emission and construction cost of each unit structure. Total CO2 emissions were estimated by multiplying CO2 emission per cost and total construction cost by each structure type. The results showed that total CO2 emission of Japan caused by port construction was 960kt. And, characteristics of CO2 emission per day were drawn by structure type.
