Sources & Notes: All data is for 2000. All calculations are based on CO2 equivalents, using 100-year global warming potentials from the IPCC (1996), based on a total global estimate <strong>of</strong><br />

41,755 MtCO2 equivalent. Land use change includes both emissions and absorptions; see Chapter 16. See Appendix 2 for detailed description <strong>of</strong> sector and end use/activity definitions, as well as data sources.<br />

Dotted lines represent flows <strong>of</strong> less than 0.1% percent <strong>of</strong> total GHG emissions.<br />
