The GREET team of Systems Assessment Center at Argonne National Laboratory is pleased to announce release of a new GREET Aviation Module.

The Systems Assessment Center at Argonne National Laboratory has developed an interactive standalone aviation module (GREET Aviation Module) to have a consistent aviation life-cycle analysis platform with the most up-to-date datasets. It is intended to evaluate the environmental impact of various aviation fuel production pathways including both fossil- and bio-derived aviation fuels. For easy access, this module uses Microsoft Excel with Visual Basic for Applications (VBA) to enable an interactive user interface.

In this release (2022 Rev2), we have updated the background datasets with the most up-to-date GREET 2022. In particular, we made the GREET Aviation Module dynamic, which interacts with the GREET fuel cycle model (GREET1) by directly reading upstream life cycle energy uses and emissions for key inputs to various stages in sustainable aviation fuel production pathways. The dynamic version enables changing the default settings of the GREET1 model as related to SAF inputs. After clicking the “Read from GREET” button in the LCProfile tab, the module will import updated conditions from the GREET1 file in the same folder. Note that this button will only be applicable with GREET version 2022 or later.
