About this data
Consumption of various controlled substances. These include Bromochloromethane (BCM), Carbon Tetrachloride (CTC), Chlorofluorocarbons (CFCs), Hydrobromofluorocarbons (HBFCs), Hydrochlorofluorocarbons (HCFCs), Hydrofluorocarbons (HFCs), Methyl Bromide (MB), Methyl Chloroform (TCA) and Other Fully Halogenated CFCs. This is measured as an index relative to emissions in the year 1986 (1986 = 100).
