For trade-content matrix \(C\) returned by calc_trades_content:

\[\mathrm{Exports}_o = \sum_{d\ne o} C_{od}.\]

Summation is over destination Regions; the same-label domestic entry is excluded. With aggregate=False, this formula is applied separately to intermediate and final content.

db.calc_embodied_exports(...) collapses db.calc_trades_content(...) into embodied export accounts by origin Region.

For each origin Region, MARIO sums the corresponding trade-content row and removes the same-label diagonal entry, so domestic content is not counted as an export. When aggregate=False, the output keeps separate Intermediate and Final columns.

indicator, item, scenario, method, clusters, clusters_direction, intermediate, final and aggregate behave like they do in db.calc_trades_content(...).

Database.calc_embodied_exports(

indicator,

item=None,

scenario='baseline',

method='total',

clusters=None,

clusters_direction='both',

intermediate=True,

final=True,

aggregate=True,

)

Calculate embodied exports by origin Region for one indicator.

This method collapses calc_trades_content(...) by summing each origin row and removing the same-label diagonal contribution. With aggregate=False, the output keeps separate Intermediate and Final columns.
