We are aware that web interfaces of national databases such as Nabisy may not appear compatible with the Annex VI, RED II method. We recommend entering the feedstocks individually but using the same GHG value for all co-digested feedstocks. In addition, it may help to contact the national databases directly (i.e. nabisy@ble.de) and request an update of the interface to the current method. Please also see the ISCC System Update from 4 March 2024 in which we shared an information letter from Nabisy on the calculation of greenhouse gas values in case of co-digestion.
