How to update the LCIA Methods in openLCA:

If you want to update the method package in a database that already contains the previous version, you have different options:

  • Delete the current version of the method package (both methods and impact categories folders) and then import the latest one,
  • Import the latest one and use the option “Overwrite all existing datasets”. This option will overwrite all the existing version of the method package with the newest one. At the end you will see the new folders and the old ones (both of methods and impact categories) which will be empty and you can safely delete.

We recommend to make a copy or a backup of the database in use before making any changes. Moreover, it’s not possible to have different version of the method package within the same database. In that case, we advise to have two copies of the same database with different versions of the methods imported.
