Where are we with banning the importation of the HCFC blowing agent R141b in terms of South Africa’s phase-down schedule for ozone depleting substances?
As a signatory of the Montreal Protocol, South Africa phased out the importation and production of CFCs on 1 January 1996. Because of the high ozone depletion potential (ODP) of CFCs like R11, R12, and R502, the international community first focused on the phasing out of these man-made substances to halt the damage to the ozone layer at between 10 and 30km above the earth’s surface.
