While some parties feel they have a moral duty to deal with
HFCs even if they are a threat to climate, and the Montreal
Protocol has a better chance of dealing with them successfully,
others feel they have just committed to transition from HCFCs to
HFCs, and appropriate, viable alternatives are not yet available
to replace HFCs. The former have put forward a proposal for an
amendment to phase-down HFCs. The latter have opposed such
an amendment ever since it was first proposed five years ago.
The debate is getting increasingly acrimonious, and any hint of
progress was quickly vaporized in the past, as it also appeared to
be at this meeting.
