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. The software is fully transparent and can be modified by anyone.

Besides being open source and free, openLCA offers...

  • professional life cycle modeling,

  • up-to-date usability,

  • a broad choice of life cycle databases (probably the largest worldwide), and

  • fluent collaboration for teams.


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