LCIA formatter

The LCIA formatter, or lciafmt, is a Python tool for standardizing the format and flows of life cycle impact assessment (LCIA) data. The tool acquires LCIA data transparently from its original source, cleans the data, shapes them into a standard format using the LCIAmethod format, and optionally applies flow mappings as defined in the Federal LCA Commons Elementary Flow List. The result can be exported to all formats supported by the pandas package (e.g. Excel, CSV) or the openLCA JSON-LD format.

The LCIA Formatter v1 was peer-reviewed internally at USEPA and externally through the Journal of Open Source software. An article describing the LCIA Formatter was published by JOSS.

Installation Instructions

lciafmt requires Python 3.9 or greater.

Install a release directly from github using pip. From a command line interface, run:

pip install git+https://github.com/USEPA/LCIAformatter.git@v1.1.0#egg=lciafmt

where you can replace 'v1.1.0' with the version you wish to use under Releases.

Alternatively, to install from the most current point on the repository: git clone https://github.com/USEPA/LCIAformatter.git cd LCIAformatter pip install . # or pip install -e . for devs The current version contains an optional dependency on the pyodbc library to generate the Impact World+ LCIA method. Due to limitations in reading Access databases from non-Windows platforms, this will only be install on Windows machines.

This needs to be specified in the pip install command. It can be done in one of two ways:

pip install .["ImpactWorld"]

or

pip install . -r requirements.txt -r impactworld_requirements.txt

See the Wiki for further installation and use instructions or for information on how to seek support.
