Purpose

mescal is a Python package for the creation and management of life-cycle inventory databases and generation of
sustainability metrics derived from Life-Cycle Assessment (LCA), to be integrated Energy System Models (ESM) in order to
make energy transition pathways sustainability assessment more holistic, transparent and reproducible.

mescal is a specialized package of the Brightway Software Framework, mainly relying on the bw2calc
and wurst Python packages.

mescal was designed for all researchers and modellers aiming to include life-cycle assessment (LCA) in their analyses,
without necessarily being LCA experts. On the other hand, mescal is also designed for LCA experts who want to
integrate projections from ESM into their LCA studies.

workflow of the mescal methodology

Life-Cycle Inventory (LCI) datasets are taken from ecoinvent and possibly other sources if some of the ESM technologies
are not covered in the ecoinvent database, e.g., premise additional inventories. These LCI datasets are mapped
to the ESM technologies and resources. Systematic transformations are operated on LCI datasets, including
regionalization, databases harmonization, double-counting removal, and life-cycle impact assessment.
LCA indicators are then ready to be integrated in the ESM.

How to use mescal?

You can follow this example notebook to learn how to use mescal. It presents a real application using the
EnergyScope model.
