Adding transport phase in impacts object

[da-ekchajzer]

Problem

Today, only Manufacture and Usage impacts are implemented. We could add the impacts of device transportation.

Solution

We should consider two transportation phases :

• inter-state : mostly done by boat, plane and/or train
• intra-state : mostly done by trucks and trains

The functional unit should be kg per km.

"model":{
   "weight": 35,
    ...
},
"transport":{
   "interstate-km": 20204,
   "intrastate-km": 1000,
   "interstate-mode": "plane",
   "intrastate-mode": "truck"
}

interstate_impact = weight * interstate_km * allocation_factor(interstate_impact)
intrastate_impact = weight * intrastate_km * allocation_factor(intrastate_mode)

Default values

• A default weight should be provided per type of devices
• A default transport object should be provided :
  • default interstate should be China-Europe by plane (to maximize)
  • default intrastate should be set at 1000 km by trucks (ADEME/ARCEP approach + maximizing)

Additional context or elements

• Ecotransit methodology can be used to identify impacts factors
• Inspired by ADEME/ARCEP report
