14 May 2008: UN Secretary-General Ban Ki-moon, in his capacity as depositary of the Montreal Protocol on Substances that Deplete the Ozone Layer, has advised parties that the adjustments made to the Montreal Protocol at the Nineteenth Meeting of the Parties to the Protocol (17-21 September 2007) will enter into force, and become binding to all parties, on 14 May 2008.

The changes accelerate the phase-out of hydrochlorofluorocarbons (HCFCs) in developed and developing countries.
The adjustments came about in reaction to recent increases in HCFC production in developing countries, which have been linked to unintended perverse incentives unintentionally created by the Kyoto Protocol’s Clean Development Mechanism.
