As the Montreal Protocol Meeting of the Parties (MOP 25) entered the second day of discussions on Tuesday, South Africa called for setting up a formal contact group to discuss how the problem of hydrofluorocarbons (HFCs) can be addressed under the international treaty. (For an official decision to emerge from the Protocol, an issue first needs to be formally discussed under a contact group.) By doing so, South Africa broke ranks with other BASIC (Brazil, South Africa, India and China) countries that are opposed to setting up such a contact group on HFCs under the treaty. China, member of this coalition of emerging economies, called for a formal discussion group, talks under which are not legally binding upon parties to the Montreal Protocol.
