It depends. The AusLCI and EcoInvent Databases are updated about every year. However, if the updates only affect the section data that eTool doesn’t use (i.e. agriculture), it may not be necessary for us to update our database. However, since we are constantly scrutinising and reviewing the data, there may be times when we find errors in the database and will need to update it to correct them. Therefore, I would say that on average we may be updating our databases about every 1-2 years depending on the factors mentioned above.
