1) The category "other" includes HFC-408a, -409a, -410a
+ HFC-365, HFC-23 and HFC-227 (in the emission calculation a worst-case figure
is used on the basis of the GWP value for HFC-410a). There were, however, no imports
in 2002.
n.i.= not informed
n.e. = not evaluated
2) The category "other" includes HFC -408a, -409a,
