Dina, as said, the categories are empty since you use a database that does not support EN15804, and we are offering one that does suport EN15804.
- we somehow are quite often target of trolls it seems, or of users who expect that we can offer anything for free because the software is free - but of course, we also have expenses and expect fair payment for our work. But we created openLCA since in our impression, current LCA software is too expensive, which is a bottleneck to LCA application
- openLCA in industry: We clearly have more academic users but know of quite some companies who use, and continue to use, openLCA; it is true that some take openLCA less seriously than other LCA software because it is free, but those who commit to using it also typically stay; and we see increasing demand from industry currently. We are working on a version to add some features more interesting for business use currently btw.
