Hi, for use with openLCA, it is recommended to purchase from Nexus as the ecoinvent files from ecoinvent do not work in openLCA and Nexus will give you access to the ecoinvent site as well, so that you get access to the ecoinvent original files. If you have purchased from ecoinvent, we will charge a registration fee to get the ecoinvent version for openLCA, from Nexus. And we sell the license in Nexus for the same price as ecoinvent on the ecoinvent site (also for the maintenance, btw.?), thus it is overall cheaper to buy from Nexus if you want to use ecoinvent in openLCA.
Best wishes,
Andreas
