# Customized Approach to Greenhouse Gas Emissions Calculations in Railway Freight Transport
## Appendix B  
Semi-structured interviews--aggregated answers:  
1. Is the field of producing GHG emissions from RFT relevant for your company? Yes, of course. This area is very popular for our company, because our company strives to minimize the negative impacts on the environment. The issue of GHG emission calculations is one of the tools to achieve the above goal.
2. Do you use any tool for calculating GHG emissions? Our company does not currently use any RFT emissions calculators or another similar tool. There is no appropriate GHG emissions calculator available to meet our assumptions and restrictive conditions. Our logistic processes related to the RFT are very comprehensive and specific with many unique conditions. There are currently no suitable RFT emission calculators or another similar tool that contains all required specifics of our company.  
Where do you analyze the GHG emissions produced by FFT? We track produced GHG emissions by FFT in inbound and outbound logistics. The most important for us are transports within outbound logistics to foreign plants and to customers.
4. What emissions do you track in logistic processes connected with FFT? We track CO\({}_{2}\) and SO\({}_{2}\) emissions as part of logistic processes.
5. What kind of freight do you transport using FFT? We transport predominantly passenger cars (PC), car bodies (CB), and freight containers (FC). We have three kinds of vehicles there are: vehicles for the transportation of PC (see Appendix C, Table A1), vehicles for the transportation of CB (see Appendix D, Table A2), vehicles for the transportation of FC (see Appendix E, Table A3).
6. Define restrictive conditions for FFT. The fundamental restrictive conditions are the maximum freight weight of the vehicle, the maximum load volume of the vehicle and vehicle selection by type of transported freight. The following specific conditions are further applied to the transport of PC: * Different PC (PC1-PC8) with different weights (WPC1-WPC8) are transported. * The maximum number of PC is 10 PC for transport from plant A on one railway car. * The maximum number of PC is 11 PC for transport from plant B on one railway car. The following specific conditions are further applied to the transport of CB: * Different CB (CB\({}_{1}\)-CB\({}_{2}\)) with different weights (V\({}_{\text{CB1}}\)-V\({}_{\text{CB2}}\)) are transported. * Each CB is transported together with a pallet of different pallet weights (V\({}_{\text{P1}}\)-V\({}_{\text{P2}}\)). * The maximum number of transported CB including pellets is as follows: RC\({}_{26}\)--8 CB, RC\({}_{27}\)--10 CB, RC\({}_{28}\)--8 CB, RC\({}_{29}\)--10 CB. The following specific conditions are further applied to the transport of FC: * Different FC (FC\({}_{1}\)-FC\({}_{3}\)) with different weights (V\({}_{\text{FC1}}\)-V\({}_{\text{FC3}}\)) are transported (V\({}_{\text{FC1}}\) = 2.2 t, V\({}_{\text{FC2}}\) = 3.8 t, V\({}_{\text{FC3}}\) = 3.9 t). * FC are preferably loaded on Sggns S183 railway cars (RC\({}_{32}\)). * The options for loading railway cars are as follows: for Lgs 580 (RC\({}_{30}\))--two FC\({}_{1}\) or one FC\({}_{2}\) or one FC\({}_{3}\), for one FC\({}_{2}\) or one FC\({}_{3}\), for Sggns S183 (RC\({}_{32}\))--four FC\({}_{1}\) or two FC\({}_{2}\) or two FC\({}_{3}\), two FC\({}_{1}\) and one FC\({}_{2}\), two FC\({}_{1}\) and one FC\({}_{3}\), one FC\({}_{2}\) and one FC\({}_{3}\). * The aim is to maximize the load of railway cars during loading. * What type of transport do you use? We use one-way transport and return transport. When it is a one-way transport, our company uses multiplying of the produced emissions by specific coefficient. * How do you want to present the resulting GHG emissions? We would like to present the results in the form of: total GHG emissions, average GHG emissions per 1 km, average GHG emissions per 1 t and average GHG emissions per 1 km and according to the calculation approach and origin of GHG emissions (FO and BO).
