The production volumes and market shares of land tenure and LUC have a high level of uncertainty, which can have large impacts in overall LCIA results (Novaes et al. 2017). However, the uncertainty associated with these data could not easily be reflected in the datasets. Uncertainty assessments should take this limitation into consideration.
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.
This dataset represents a market activity in the ecoinvent database. A market activity is an activity that does not transform inputs, but simply transfers a specific intermediate exchange (i.e. products, including wastes and by-products) from supplying transforming activities to other transforming activities that demand this intermediate exchange as an input, e.g. from glycerine at the supplier to glycerine at the consumer. A market dataset collects all activities with the same reference product in a certain geographical region. Furthermore, it typically includes average transport requirements for that product within the geography in question, as well as inputs of the product itself to cover any losses in trade and transport. In other words, market activities are generally intended to represent consumption mixes of a given product in a certain geographical region.
