Production of ozone depleting substances in EEA member countries, 1986-2007
Additional information
Production is defined under Article 1(5) of the Montreal Protocol as production minus the amount destroyed minus the amount entirely used as feedstock in the manufacture of other chemicals. Calculated production may therefore be negative in cases where the destroyed amounts exceed the production. Since the figures are for each calendar year, it is quite possible that in some years the feedstock figure may exceed the production figure of that year, if the feedstock use is from a carry-over stock. The calculated production could be negative in such cases.
