All data is for 2000. All calculations are based on CO
2
equivalents, using 100-year global warming potentials from the IPCC
(1996), based on a total global estimate of 41 755 MtCO
2
equivalent. Land use change includes both emissions and absorptions.
Dotted lines represent flows of less than 0.1% percent of total GHG emissions.
