Note: Rest of the world refers to world emissions minus the top ten emitters among IPAC-covered countries. World emissions include national inventories plus international bunkers and a LULUCF bookkeeping estimate to account for differences in reporting methods. Individual country emissions reflect national inventories excluding LULUCF, as a LULUCF bookkeeping estimate is applied at the global level.
