GLOBAL PRODUCTION AND EMISSIONS OF BROMOCHLORODIFLUOROMETHANE AND BROMOTRIFLUOROMETHANE (HALON-1211 AND HALON-1301)

Data for the global production of Halons 1211 and 1301 have been assembled from audited values submitted by producers within OECD (Organisation for Economic Cooperation and Development, comprising Australia, Canada, Japan, New Zealand, U.S.A. and European countries, excluding those in the former Eastern bloc) and from estimates of production in U.S.S.R. and China. Aggregate values for production are accurate to within 3% for Halon 1211 and 2% for Halon 1301. Annual emissions of these Halons have been calculated from the production figures and industrial estimates of the annual percentages released. The totals of these emissions up to and including 1990 are 112,946 tonnes of Halon 1211 and 48,377 tonnes of Halon 1301; values which, after discounting for the atmospheric lifetimes of these compounds, are generally consistent with measured atmospheric concentrations.
