Answer:

Halons, carbon tetra chloride, methyl chloroform, methyl bromide

Explanation:

There is a reference gas (CFC-11) This has a global warming potential (as well as ozone depletion potential) 1.0. The ozone depletion potential (ODP) of a gas is defined as the decrease in total ozone per unit mass emission of CFC-11 (CFCl3).

Two halons (chiefly CF2ClBr and CF3Br) and methyl chloroform (C2H3Cl3) have ODP values of 6, 12, and 0.1, respectively. ODP is an independent of the length of time required for depletion of ozone to take place.

Ozone depleting substances have become an important issue of the regulatory approach. For additional information, you can visit World Meteorological Organization (The Scientific Assessment of Ozone Depletion, 2002) web site.
