Footnotes for Tables 1 to 7

a Emissions of CO2 from coke ovens and patent fuel production are calculated according to a carbon balance on the coal consumed and the coke, patent fuel, blast furnace gas and coke oven gas produced.
b Included in 1A1f Other
c Emissions of CO2 from ammonia manufacture are reported under 2B1 Ammonia Production
d Emissions from locomotives only are reported under 1A3c Railways
  Emissions from autogeneration for transport use and other stationary combustion associated with railways are reported under 1A4a Commercial/Institutional
e Emissions from stationary combustion at military installations are reported under 1A4a. Emissions from military vehicles are reported uder 1A3b
f Emissions from oil, oil/gas and gas production facilities and well testing are reported under 1B2a Oil
g Emissions given for information only and are not totalled
h The use of limestone, dolomite and chalk in glass making
i The use of soda ash in glass making
j Includes emissions from iron and steel blast furnaces and electric arc furnaces. CO2 emissions from blast furnaces are calculated from a carbon
  balance on the coke consumed and blast furnace gas emitted and carbon sequestrated in steel. Emissions from the use of limestone, dolomite and chalk in blast furnaces and flaring of blast furnace gas are also accounted for.
k Emissions of CO2 and SO2 from ferroalloy production are included in 1A2f.
l Fugitive and byproduct emissions are combined.
m The CO2 equivalent of solvent NMVOC emission in 1996 is estimated as 1554 Gg
n Yearly figures
o Field burning ceased in 1994
p Includes agricultural land use change. Net emission reported
q Agricultural set-aside.
r CO2 emission arises from liming of soils. Agricultural soils could be a net sink of methane.
s Emission of CO2 is from wetland drainage and peat extraction. Removal arises from salt marshes.
t Sewage sludge disposal by landfill is included under 6A.
u Emissions from own wastewater treatment by industry not estimated
