Generally, there are as follows:

emissions
probably the toughest of the tables to create, but would be a per kg set of emissions based on different life cycle stage types. This table may need to be expanded to account for the different A1-A3 impacts, A4 impacts, and eol impacts. However, it could also be combined since it will be a typical scenario used for each of them, so maybe it can be simplified into one table. TBD.
