Hydrochlorofluorocarbons (HCFCs) are ozone depleting substances (ODS) controlled by the Montreal Protocol on Substances that Deplete the Ozone Layer that are widely used in refrigeration and air conditioning, foam blowing and solvent applications. The Parties to the Protocol have decided to accelerate the phase-out schedule for these chemicals .
Action on HCFCs is important in that these chemicals have an impact on both ozone depletion and climate change. In terms of direct impact, the most commonly-used HCFCs have ozone depleting potentials (ODPs) ranging from 0.02 (HCFC-123) to 0.11 (HCFC-141b) and global warming potentials (GWPs) ranging from 76 (HCFC-123) to 2270 (HCFC-142b). Equipment using HCFCs consumes energy, which contributes to indirect global warming impacts.
Developing countries are close to a very important step in the new accelerated HCFC phase-out; the 2013 freeze. Taking early action that would facilitate compliance, specifically the establishment of policies and legislation, is therefore critical to a successful and smooth phase down.
