A fresh design for R&D GREET life cycle analysis tool
R&D GREET® 2023 .Net software provides the user with an easy to use and fully graphical
toolbox to perform life cycle analysis simulations of alternative
transportation fuels and vehicle technologies in a matter of a few
clicks. This new tool includes the data of the R&D GREET Excel models, a fast
algorithm for processing it and an interactive user interface. The
interface allows faster development using graphical representation of
each element in the model, and drag & drop editing approach to add and
modify data.
The R&D GREET.Net software can be only installed in Windows OS with Microsoft .Net Framework 4.5 installed.

Although a previous R&D GREET.Net version (e.g., 2022) may be able to load the latest data file in this release, it is highly recommended to upgrade the software to R&D GREET 2023. To do that:
If the old “default.greet” file you move to other places contains your modifications, it is possible to merge those changes to the new “default.greet” file. Please refer to “Data Merging” section of the “GREET-Manual.pdf” (Menu Bar→"About"→"User Manuals")
