Based on "transport, freight, inland waterways, barge, RER 2000". Inventory refers to the entire transport life cycle. Port infrastructure expenditures and environmental interventions are allocated based the yearly throughput (0.14). Vessel manufacturing is allocated based on the total kilometric performance (1'240'000km) and its transport performance (1000/unit). The energy use and combustion emissions data represent the transport of good with a barge with a carrying capacity not less than 50 tonnes operating on inland waterways.
Undefined unit processes (UPRs) are the unlinked, multi-product activity datasets that form the basis for all of the system models available in the ecoinvent database. This is the way the datasets are obtained and entered into the database by the data providers. These activity datasets are useful for investigating the environmental impacts of a specific activity (gate-to-gate), without regard to its upstream or downstream impacts.
