In previous versions of ecoinvent, products of single-output processes always had to have the same name as the activity producing it. In version 3, we have moved to a more intuitive naming: There is now a list of product names and a list of activity (process) names. This allows us to use simpler product names, and you can now identify a dataset more easily by first searching for a product and then selecting one of the activities producing it from a list.
Due to this change, the product and activity names changed for our datasets. We are working with our resellers to support a smooth transition in the software tools. Should you work with the data directly, a correspondence file, which lists all the old names with the corresponding new product and activity names, is at your disposal.
