4.4- Consumption of Ozone Depleting Substances (ODS)
This indicator is a driving force indicator. The release of ozone depleting substances to the atmosphere leads to the depletion of the Earth's ozone layer. The stratospheric ozone layer protects people and environment from harmful ultra-violet (UV) radiation emitted by the sun .
Chlorofluorocarbons (CFC) hydrochlorofluorocarbons (HCFC), halons, Carbon Tetrachloride, Methyl Chloroform used as refrigerants, cooling agents and fire extinguishers, are substances that cause depletion of the ozone layer.
Turkey has been a party to the Montreal Protocol on Substances that Deplete the Ozone Layer in 1991 and is among the developing countries of the Protocol as the A5 country. The import and consumption of ODSs’ that haven’t been produced in our country are gradually terminated in accordance with the Protocol obligations. Projects and public / sector awareness-raising activities are carried out on transition to alternative substances. Turkey is making a successful trend by implementing a faster ODS phase-out calendar than other developing countries. In Turkey, the use of substances that reduce the ozone layer during the period 2009-2016 has decreased by 97%.
Globally, consumption of ODS’s controlled under the Montreal Protocol has declined by some 98.34% worldwide in the period 1986-2015 .
