Notes: MtCO2 eq. is millions of tons of carbon dioxide equivalent. Emissions exclude those from international bunker fuels and land-use change and forestry. Countries not among the top 25 absolute emitters are shown in italics. GHG data is from 2000; other data is from 2002. GDP is measured in terms of purchasing power parity (constant 2000 international dollars).
