The research problem in this study is an energy consumption and carbon dioxide emission production modeling by temperature measurements. The temperature data was collected by GreenLC project from a temperature controlled outbound transport. The selected research questions was related on the modeling, if it is possible to calculate the energy consumption based on the temperature measurement data. What are the effective heat loads when modeling an outbound transport? Furthermore, what are the carbon dioxide emissions produced by outbound transport model? The research was based on the principles of the Green logistics and the characteristic of supply chain and outbound transport. Moreover, Modeling was based earlier studies that considered modeling temperature controlled transport and thermal features of a trailer. In addition, the energy calculations was based on thermodynamic principles and earlier energy calculation studies made on temperature controlled transport. The research problem was answered with two different energy models made from the GreenLC project outbound transport. The both models illustrated the case study closely and the cumulative energy load correlation had high values in both models. However, important finding was that, if models is wanted to reflect even more the case study more specific starting values should have been available. The research questions was also answered. The energy consumption can be calculated from the temperature measurement, if the trailer specifications are available. The most important heat loads in both energy models was the infiltration air from door-openings, the conduction heat through trailers body and the product heat load from replaced air in the trailer. Lastly, the carbon dioxide emissions was successfully calculated and found quite small. However, the infiltrations heat load produced 60 percent of the total emissions and it was found very interesting.
