Trends in total greenhouse gas emissions
For some countries the reporting of some gases, mainly the fluorinated gases (and if a few number of cases of N2O), was incomplete. Because of the relatively low weight of the F-gases in total greenhouse gas emissions, the trends presented in the chart above should reflect rather accurately the development of total greenhouse gas emissions in the four regions. Index 1990 = 100. The volume of emissions in million tonnes of CO2-equivalents in 1990 was: EU25 = 5 231; EECCA = 4 630; SEE = 620; EFTA = 106.
