When dealing with multiple batches of the same material with different sustainability characteristics, how should these batches be accounted for?

If an ISCC System User receives different GHG values, the aggregation of GHG values from incoming input materials is only possible if the product identities and GHG values are the same. Either individual values for each incoming batch or the highest GHG value (of the least performing batch) should be used for all incoming batches of the same kind of input material.
