Thanks for your query. As you’ve already pointed out, our data is based on the AusLCI datasets and there is currently no easy way for a standard eToolLCD user to pull out that information from the software. That information however will be based on industry average figures. Therefore assuming that Green Star’s assumptions are based on typical statistics, the LCI data would probably be pretty close to similar.
If you wish, you can actually download the material datasets from AusLCI in spreadsheet format and inspect the data yourself. All you need to do is to register an account and you can download those spreadsheets for free. 🙂
