If I have understood well your question, it think that SimaPro is the most suitable software for your purpose: version 8 is already available. This software is usable for a wide range of systems and enables development of life cycle assessment, carbon footprint, ecological footprint, cumulative energy demand and many others. If you go on line e look for "SimaPro", you can get other useful information, thus allowing you to understand better if it suitable for your type of project or not.

I hope my information has been helpful for you.

Yours truly

Currently, I am OpenLCA for life cycle assessment, which is available for free.
