Parties to the Montreal Protocol on Substances that Deplete the Ozone Layer will achieve the final phase-out of ozone-depleting chlorofluorocarbons (CFCs) this year with the phase-out of CFCs used in metered-dose inhalers (MDIs).
More than 98% of the CFCs used in MDIs have already been phased out, and will disappear completely in 2016, a significant milestone following 30 years of concerted global action to protect the ozone layer.
Affordable CFC-free alternatives for all inhaled treatments have been developed over the last 20 years, and are now available worldwide.
In 1996, when CFC-based aerosols were phased out in developed countries, CFC-free replacement inhalers were not available for the hundreds of millions of patients with asthma/chronic obstructive pulmonary disease worldwide who relied on them, and so a temporary exemption was allowed. MORE
