My LCA studies is mostly focus on the end of life (waste management) part of life cycle. In every single processes that I use from ecoinvent are include the production processes, e.g. for transportation, I`m using small truck or van to transport the waste from from one point to another point, then when I try to do the model graph, I can`t find process that not involve production part, so it`s still involve production process of the truck or van. Because I`m not considering the emissions from the production part, only during transporting. Could you help me on this?
