ulcarchetype is a Python library that provides some simple tools to characterize the uncertainty due to archetype "underspecification" in life cycle assessment (i.e. when the "subcompartment" is not specified). It is meant to be used with the LCA software Brightway2.
Use the package manager pip to install ulcarchetype
pip install ulcarchetypeimport brightway2 as bw
from ulcarchetype.utils import get_cf_info,minmax_archetype,cf_add_uncertainty
method = bw.methods.random()
cf_df = get_cf_info(method) # returns a dataframe with data on characterisation factors
minmax_archetype(cf_df) # returns a dataframe with data needed to define uncertain CFs
# or simply
cf_add_uncertainty(method) # returns a list of CFs taking into account archetype uncertaintyPull requests are welcome. For major changes, please open an issue first to discuss what you would like to change.
