+ 1 ppmv = 1 part per million by volume; 1 ppbv = 1 part per billion by volume; 1 pptv = 1 part per trillion (million million) by volume.
++ No single lifetime for CO2 can be defined because of the different rates of uptake by different sink processes.
+++ This has been defined as an adjustment time which takes into account the indirect effect of methane on its own lifetime.
* The growth rates of CO2 , CH4 and N2O are averaged over the decade beginning 1984; halocarbon growth rates are based on recent years (1990s).
(Ed. note: 1kg of carbon = 3.664 kg of CO2.)

Notes: Primary energy is recovered or gathered directly from natural sources (e.g., mined coal, collected biomass, or harnessed hydroelectricity), then is converted into fuels and electricity (e.g., electricity, gasoline, and charcoal), resulting in final energy after distribution and delivery to the point of consumption. (An EJ, or exajoule, is one billion joules, equal to the energy content of about 24 million tonnes of oil ed.)
Nuclear and hydropower electricity have been converted into primary thermal equivalent, with an average factor of 38.5% (WEC, 1983).
Feedstocks represent nonenergy use of hydrocarbons.

Notes: Gg = 1,000 tonnes
a.In accordance with decision 9/CP.2 some Parties with economies in transition use base years other than 1990: Bulgaria (1988), Hungary (average of 1985-87), Poland (1988) and Romania (1989).
b.The baseline figure used for calculation of percentage change may differ than that of the 1990 figure given in this table due to use of a different baseline other than 1990, use of only a subset of the 1990 figure, subsequent updating of inventory data, calibration of projection models or rounding.
c.Party did not provide estimates for all years subsequent to 1990.
