1) The category "other" includes HFC-365, R413a, R417a Isceon 79 and HFC-245fa, (in the emission calculation the emission factor for HFC-410a is used).
2) The category "other" includes HFC -408a, -409a, -410a, (in the emission calculation a worst-case scenario is used on the basis of the GWP value for HFC-410a).
