Those of you that have an ecoinvent 3 licence can of course already login at the ecoinvent website and inspect the data sets there. Of course we are doing our best to make ecoinvent 3 available fast and in good quality.

openLCA is a free, professional Life Cycle Assessment (LCA) and Footprint software with a broad range of features and many available databases, created by GreenDelta since 2006. It is an open source software; the software and its source code is freely available.

Besides being open source and free, openLCA offers...
professional life cycle modeling,
up-to-date usability,
the broadest choice of available databases, and
seamless collaboration.

This leads us to say: "openLCA - doing more with less".

We invite you to take a tour through the site and to explore openLCA. If you have any comments, please let us know. Thanks in advance.
