FAQs

In rare and exceptional situations, an activity dataset that includes confidential information may be kept inaccessible as a unit process dataset while still being included in calculations of accumulated systems datasets. Confidential datasets are subject to the same Data quality guidelines as any other ecoinvent dataset and are reviewed on a unit process level internally, but the review procedure is performed under the direct management of the ecoinvent team.

Most of the few confidential datasets are from older versions of the database, and in general ecoinvent aims to replace such data with transparent unit process data as soon as possible.
