Transport takes place on four main elements: Air, rail, road, and sea. The question of which of these four elements is more environmentally friendly is a subject that has been studied frequently. In order to give a full answer to such a question, all modes of transport (including vehicles of transport) must be comprehensively examined from a life cycle perspective. In this study, the CO2eq, which is identified as the greenhouse gas impact of different greenhouse gases is measured from the CO2 unit, emissions of the four modes of transport in the case of carrying 1 tkm of unit load, which means the transport of 1 t of cargo at a distance of 1 km, were calculated. The first reason for choosing only CO2eq emissions is that the method used calculates only CO2eq emissions, while the second reason is that global warming is the most important environmental impact category for different transport modes. Calculations were made according to the Intergovernmental Panel for Climate Change (IPCC) method, which considers only CO2eq emissions and thus can be accepted more accurate than other methods, and life cycle approach and the effects were measured at 20-, 100-, and 500-year periods, which are called individualistic, hierarchist, and egalitarian, respectively. Accordingly, maritime transport is the most environmentally friendly mode of transport in all three periods, and air transport has the largest share in greenhouse gas production. The main aim of the study is to draw attention to the life cycle perspective in the calculation of greenhouse gas emissions and to compare the short-, medium- and long-term effects of transportation modes both with themselves and with each other.
