Calculation Model for Energy Carbon Emission of Building Material Transportation

To establish an analytic model for carbon emission of building lifecycle, based on life cycle theory and the factors affecting energy consumption in building material transportation(BMT), a calculation method for carbon emission benchmark of BMT was proposed. Furthermore, with the coefficient of carbon emission by transportation means and the coefficient of transportation distance, a calculation model for carbon emission of BMT was put forward. Taking steel as a case study, it is found that the benchmark of carbon emission from steel transportation is 15.86 kg/t steel. Railway transportation is the cleanest way, accounting for one tenth of that of highway and a half to one third of that of waterway.
