Methods for background life cycle inventory

The open-source model for background life cycle inventory of bio-based sectors consists of a set of documents, tutorials, and data templates:

·       Model description for background life cycle inventory of bio-based sectors

The document consists of a brief description of the theoretical basis of prospective LCA and a tiered-based approach for generating background databases.

·       A tutorial for generating background life cycle inventories, Tier 1

The document contains a tutorial for generating a single background database with an attributional approach.

·       A tutorial for generating background life cycle inventories, Tier 1

The document contains a tutorial for generating a single background database with a consequential approach.

·       A tutorial for generating background life cycle inventories, Tier 2

The document contains a tutorial for generating multiple background databases with an attributional approach.

·       A tutorial for generating background life cycle inventories, Tier 2

The document contains a tutorial for generating multiple background databases with a consequential approach.

·       An example of the foreground inventory format to be modified by the user (an excel file)

The example provides a template for compiling the users’ own Brightway2 foreground inventories and connecting them to the users’ prospective background databases by using a Jupyter notebook.  More detailed instructions can be found in the Tier 2 tutorials.

·       Environment specifications (.yml file)

The Yaml Source File contains the specifications for the environment used in the tutorials in Task 1.1.
