Hi,
I see you work in LCA commons. If you use this flow as input make sure you connect it via 'provider' to the process 'Transport, transit bus, CNG powered' (you will see it in the process inputs or the model graph of the product system). Then you should have all the emissions related to the transport in your results. The process also has direct emissions so, even if you don't connect the supply chain of it, there should be emissions accounted for.
Hope this helps
