I want to model the transportation of components from suppliers to the main manufacturing facility. Every shipment is made by truck. I plan on using predefined processes available in the database I use. However, I am a bit perplexed concerning the unit kgkm (or tkm).
Let's say there are two scenarios. 1) A truck of a certain type transports a 10 kg package a distance of 100 km. 2) The same truck transports a 10 000 kg package a distance of 100 meters. For both scenarios, as I've understood it, one would enter the value 10 000 kgkm (10*100 = 10 000*0.1 = 1000 kgkm). But it would logically seem reasonable that scenario 1 would produce more emissions than scenario 2, or is that an unreasonable assumption?
Is there something that I've misunderstood about how these processes are meant to be used and interpreted?
