Frequently Asked Questions

Known limitations

We are aware of some limitations and plan to address them. If any of these limitations are limiting problem for you, please feel free to contact us to let us know so we can either prioritize fixing the limitation or help you fix it.

Versions

Appa Build currently works with Brightway 2.4.7 and lca_algebraic 1.0.0. This includes working with Python above version 3.10. This limits EcoInvent version support to version 3.9.1.

Latest version of Brightway, which supports all versions of EcoInvent, is currently integrated in the dev branch, and will be integrated into a new release after thoroughly tests.

Background databases

At the moment only the EcoInvent background database is supported, as we haven’t been able to access and test other databases supported by Brightway. Data from other databases can nonetheless be imported at the impact level.

Methods

Appa Run uses Enum to associate Brightway method names with comprehensive strings. We currently only implemented an Enum for PEF v3.0 LCIA methods and plan to support other methods as well.

You can easily extend the mapping to other LCIA methods. If you do so, it may be a good idea of contribution and could be integrated into Appa LCA’s source code.
