The Montreal Protocol on Substances That Deplete the Ozone Layer is a landmark international agreement designed to protect the stratospheric ozone layer from depletion due to ozone (O3) reaction with halogenated hydrocarbons.

- The treaty calls for the phase out of Ozone Depleting Substances (ODS) and provides a timetable on the ban and elimination of their production. The treaty provides a timetable on the phase-out of ODS, taking into consideration the allowance for developing countries (Article 5) to delay their compliance with the prescribed control measures by ten years.
Parties to the Protocol are required to report annually on production and consumption of ozone depleting substances.

The DENR through the EMB has already completed the ban on five of the six groups of Ozone Depleting Substances (ODS) namely: chlorofluorocarbons (CFCs), halons, carbon tetrachloride (CTC), methyl chloroform and methyl bromide (non-quarantine pre-shipment or non-QPS). The remaining group of the ODS to be phased out is hydrochlorofluorocarbons or HCFCs. HCFC-141b, widely used as a blowing agent, is the first species of HCFCs to be phased-out in the country because it has the highest ozone-depleting potential (ODP).
In 2004, the Philippines released a Chemical Control Order (CCO) for the phase-out of ODS. It is expected that 97.5% of HCFC blends have been prohibited by 2030.
