Specific data for specific inventory items may be based on sub-samples for which detailed data was available. Vessel dimensions: 34 - 275 m3 (16 - 34 m length).
System boundaries and relation between activities
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.
