Article 1.
Objectives

This Decree specifies necessary principles, rules and measures for the control of the
import, export and use of Ozone Depleting Substances (ODS), in order to protect the
environment and prevent the depletion of the ozone layer in accordance with the Country
Program on the phase-out of ODS under the Montreal Protocol, ensuring that any development is
in compliance with the government’s socio-economic plan.

Article 2

Article 2.
Definitions
ODS are chemical substances that have the potential to react with ozone molecules in the
stratosphere. ODS are basically chlorinated, fluorinated or brominated hydrocarbons and include:
− Chlorofluorocarbons (CFCs);
− Hydrochlorofluorocarbons (HCFCs);
− Halons;
− Hydrobromofluorocarbons (HBFCs);
− Bromochloromethane;
− Methyl chloroform;
− Carbon tetrachloride; and
− Methyl bromide.

The ozone layer is a term used to describe the presence of ozone molecules in the
stratosphere, which is that part of the atmosphere at 10-50 km height above our earth level. It
acts as a filter to prevent the harmful ultraviolet radiation (UV-B,C), which is a highly energetic
light that originates from the sun, from reaching the earth. Therefore the ozone layer is vital to
life on the planet’s surface.

Article 3.
Controlled substances
Controlled substances include: Cholorofluorocarbon-11 (CFC-11), Chlorofluorocarbon-
12 (CFC-12), Hydrochlorofluorocarbon-22 (HCFC-22), R-502, Halon-1211, Halon-1301, Halon-
2402, 1,1,1-Trichloroethane and Methyl bromide.
