There is a new GHGenius website. Unfortunately you will have to re-register to access the model and some of the reports; however you can use the same user name and password that you previously used.

Along with a new version of the model (GHGenius 5.0) there are new reports posted.  The 3 and 4 series of the GHGenius models and some of the previously posted reports are no longer available for download.

The new model has many new data series, new pathways, new regions, new features, new macros, and a new look that avoids the Excel limitations that previous versions experienced. It has been created by the same team that developed the 2, 3 and 4 series models following the same approaches to data quality.
