At the 22nd Meeting of the Parties to the Montreal Protocol (MOP-22), two draft decisions on amendments to the Protocol to address HFCs were presented by the US, on behalf of Canada and Mexico (UNEP/ OzL.Pro.22/5), and by the Federated States of Micronesia (UNEP/OzL.Pro.22/6), advocating for a phase down of HFCs under the Protocol to mitigate the climate change impact of their projected use increase.

The proposals were triggered by projections showing that HFC emissions are likely to rise by roughly 300% by 2050 triggered these proposals (EFCTC comments here :EFCTC POSITION PAPER ON PROJECTED HFC EMISSIONS.
The MOP adopted no decision on these draft proposals, but 91 countries signed on to a US-led declaration, which was included in the MOP 22 Report as Annex III. The declaration encourages Parties to promote policies and measures aimed at selecting low-GWP alternatives to HCFCs and other ozone-depleting substances.
Key Points of the North American HFC Submission to the Montreal Protocol:
Due to differences of views amongst delegations (Brazil, India and China objecting), no decision was adopted by the MOP. Nevertheless 91 countries signed on to a US-led declaration, which was annexed to the MOP 22 Report.
Declaration on the global transition away from hydrochlorofluorocarbons (HCFCs) and chlorofluorocarbons (CFCs)
India, China and Brazil remained united in their resistance to including HFC-controls under the Protocol, underlining that HFCs are not ODS and thus remain outside the scope of this regime, preferring to address this under the UNFCCC.
More recently, an India-US Task force on HFCs has been established, which will include industry representatives, scientists, and government officials from India and the US to evaluate a phase-down of the production and use of HFCs under the Montreal Protocol.
The US have also requested the Ozone Secretariat to post on its web site the US Declaration, and inviting countries to associate themselves with it.
