QAFCO provides sustainability reports on it's website dating back to 2012. This is the 2015 version.
I didn't check whether this report was on WikiRate already and duplicated this source, I will see if I can delete my version.
This sustainability report has an excellent GRI Table which can be found on page 39 of the PDF (page 74 of the report). This table references to the correct report page where the metric can be located.
