ecoSpold Format

ecoSpold is a name for a format used by ecoinvent to create life cycle inventories. This format sets up standards on what are mandatory and what are optional fields for a standard life cycle inventory. While the ecoSpold 1 format is used for ecoinvent version 1 and 2, it is the ecoSpold2 format for ecoinvent version 3. The ecoSpold2 format offers many new fields, such as mathematical relation, variable names or properties of an exchange which were not available in the older ecoSpold1 format.
