unfold: removing the barriers to sharing and reproducing prospective life-cycle assessment databases

Abstract

unfold is a Python package that allows reproducing life-cycle databases which partially build on a data source that cannot be shared. It produces data packages that contain the differences between the databases to share and the licensed data source. The data package also includes a metadata file describing the databases, the author, and other helpful information. unfold allows one to pack and unpack any databases from a single data package to ease the sharing and reproducibility of prospective or scenario-based life-cycle assessment databases.

MARIO: A Versatile and User-Friendly Software for Building Input-Output Models

“…Recently, other Python packages such as pycirk [11,12], and pyLCAIO [13] have also been developed to enable modeling of Circular Economy scenarios and streamline the hybridization of process-based Life Cycle Assessment and Environmentally Extended IO databases. Recently, unfold was released, a repository that improves the packaging and sharing of data, making it easier to reproduce life-cycle databases that are based on proprietary data sources [14].…”
