pyLCAIO
pyLCAIO is a Python package to automatically hybridize the ecoinvent database with the exiobase database. In other
words, ecoinvent processes will be added inputs which are deemed missing from the process description. Typical such inputs
are services, such as business trips, banking, insurance, advertisement, IT, etc. Hybridizing allows to complete the scope
of the data to englobe the whole economy instead of being confined to the sectors covered by ecoinvent.
For instance, here we show the process of production of rice in China from ecoinvent. After hybridization with
pyLCAIO, the process is added wholesale and retail services, support transport services, etc. based on the average usage
of such services by the corresponding sector of activity in exiobase (i.e., for rice -> Paddy rice))
Then, in the LCI calculations, the impact of those added inputs is accounted for to obtain a more complete impact assessment.
Here in the example shown, those added inputs only account for a ~2% additional increase but the average increase is
around 9% for the GWP100 indicator.
As of the v3, pyLCAIO is only usable through the brightway2 LCA software.
