Chlorofluorocarbons (CFCs) and other halogenated ozone depletingsubstances (ODS) are mainly responsible for man-made chemicalozone depletion. The total amount of effective halogens (chlorine and bromine) in the stratosphere can be calculated and are known as the equivalent effective stratospheric chlorine (EESC).
