With permission of the ecoinvent centre, we are happy to be able to provide, for free, the LCIA methods of the ecoinvent database. LCIA methods packs for the ecoinvent databases 2.2, 3.01, 3.1, 3.2 and 3.3 are available for download in openLCA Nexus. These LCIA methods should be used to reproduce the LCIA results published by the ecoinvent centre. They are not intended to be used with other openLCA Nexus databases because the impact characterisation factors included in them refer only to the openLCA elementary flows used by the ecoinvent databases. If you have any questions or comments, please let us know!
