p. 3. l. 71: the regulations of HFCs in the Kigali amendment are actually rather complicated. I suggest to either explain them in detail or (my suggestion) just state that HFCs are now included in the MP, but that no immediate reduction are foreseen.

p. 21. l. 635: should this be emissions instead of sensitivities?

p. 21, l. 636: you might want to point out that the ratio of 1.85 is actually prescribed.

p. 21. l. 640. Could you comment more on the differences derived for HFC-152a? Are they outside the estaimted uncertainties?

p. 27. l. 830.: This sentence is a bit ambiguous. I suggest rephrasing: ... emissions of HFC-152a are reported in the country where the consumer product is manufactured, not in the country where emissions are likely to occur during use or disposal.

p. 31, l. 951.: I suggest to replace "are laregely independent" by a statement that the estimates sty with the quoted uncertainty range.

additional comment: please include somewhere (e.g. Figure caption where it is first used) that ppt refers to pmol mol-1, which is the SI unit
