There are significant imports of Other goods and some of Used goods (see rows from t_df from 2012 these are in million current USD)

IOCode CA CN EU JP MX APAC ROW
Used 2907 325 1456 179 713 360 578
Other 7766 3381 55516 12738 5021 15549 20653

but they get dropped after this merge because they are not in the concordance.

These would account for substantial embodied emissions and need to be handled.

A test of the quantity of imports before and after merging in this step could help identify and prevent such data loss

Review those exiobase sectors that don't match at all - those are likely to be in this "other" category

bl-young commented 6 months ago

USED data was getting dropped because the sector mapped to USED from exiobase has no exports to the US (in exiobase). this is fixed with https://github.com/USEPA/USEEIO/commit/bf995e5887d0a9d425c783602cc29697c37f2d20

The BEA Concepts and Methods in IO (the IO Manual) has a good section on defining non-comparable imports and the source data. These are mostly services consumed by US residents abroad. Foreign travel is a big one. This needs to be address in the longer term, as they these services do have embodied flows.
