PH still on track to phase out ozone-depleting chemicals

As part of the global agreement to protect the ozone layer from chemicals, the Philippines is currently focused on phasing out the supposed last batch or group of ozone-depleting substances (ODS), which are the hydrochlorofluorocarbons (HCFCs).

HCFCs are type of chemicals used in refrigerators, freezers, and air conditioning systems.

Environment Secretary Cimatu said the Philippines has always been in full compliance with the Montreal Protocol since it ratified in 1991 the global agreement to protect the ozone layer from chemicals referred to as ODS.

According to Cimatu, the Montreal Protocol on Substances that Deplete the Ozone Layer is considered as one of the most successful multilateral environmental agreements in history because it enjoys the full support and cooperation of countries like the Philippines.

In 1987, the Philippines joined the rest of the world in adopting the landmark global agreement to protect the ozone layer by stopping the production and consumption of ODS.

Four years later, in 1991, the country successfully completed the ratification of the Montreal Protocol.

Cimatu said that from 1991 to 2010, the country has fulfilled its commitment of phasing out the first batch or group of ODS in the manufacturing and servicing sectors.

In 1996, the Philippines phased out carbon tetrachloride or CTC and methyl chloroform. After three years, it ended the production and consumption of halon, a chemical compound formerly used in firefighting.

Also in 1999, the country phased out chlorofluorocarbon (CFC) variants—CFC-13, CFC-114, CFC-115—used in various industries as refrigerant, propellant, solvent and cleaning agent.

Appliances, such as refrigerators and airconditioners, using CFC-11 were totally banned in 2005. Non-quarantine pre-shipment methyl bromide was also phased out in 2009, while cars having airconditioners with CFC-12 were prohibited to be registered since January 2010.

In terms of HCFCs, Cimatu said the country has made good with its implementation and has complied with the 10 percent import reduction since 2015, a target set to be achieved up to year 2019.
