The dataset for "transport, passenger car, EURO 5" includes the construction, operation, maintenance and disposal of the vehicle and road infrastructure. Is there a way to only model the effects from the operational phase?
I have modelled the data from Simons (2013) for the exhaust emissions, but when I model the outputs the results don't show up in the Product system calculation.
I was trying to assess just the effect of exhaust emissions and hence did not model Petrol as input. So basically my process had only the emissions modelled.
But when I add the fuel i.e. Petrol as input the results start showing up in the impact assessments. Why is that the case? I did not quite understand that.
