pyLCAIO

An object class to hybridize lifecycle assessment (LCA) and environmentally extended input-output (EEIO) databases.

• Only works with Python
• Read in, combine, organize, manipulate and concatenate LCA foreground and background matrices
• Combine LCA system with EEIO matrices
• Automate hybridization and correction for double-counting with two available methods (STAM and binary)
• Can currently hybridize ecoinvent3.5 with exiobase3
• Includes extrapolated additional environmental extensions for EXIOBASE
• Includes matching of ecoinvent and EXIOBASE to Impact World+
• Can accept capitals-endogenized version of EXIOBASE
• Includes regionalized characterization matrices for use with Impact World+

If you are just interested in the default hybrid database (if you do not want to or cannot run the code) you can find it here: https://zenodo.org/record/3890379

The software is still under development but has already 2 operational versions.
