What it returns

Section titled “What it returns”

The inventory is a list of elementary flows with their aggregated amounts per functional unit. These are the flows that are then multiplied by characterization factors in LCIA.

Use impacts to go directly from an activity to impact assessment scores without inspecting the inventory.
