DISTRIBUTION OF EMISSIONS OF CHLOROFLUOROCARBONS (CFC)-11, (CFC)-12, (CFC)-113, (CFC)-114 AND (CFC)-115 AMONG REPORTING AND NON-REPORTING COUNTRIES IN 1986

A country-by-country distribution of emissions of CFCs 11, 12 113, 114 and 115 has been developed using national and United Nations statistics for the year 1986. It is apparent that almost 75% of these emissions come from developed nations. To provide estimates for nations which did not report consumption statistics, a relationship between Gross Domestic Product and total consumption of CFCs has been developed. For the full data set: C = 0.0801G where C is the CFC consumption in metric tonnes and G the Gross Domestic Product in millions of US$. This equation can be used to predict CFC consumption at GDPs up to US$ 400 million with a scale uncertainty of plus or minus 38%. These uncertainties are half those of the similar, and commonly used, relationship between consumptions of CFCs and electrical power. The data set developed here could be used as input data For global atmospheric modelling.
