In order to estimate CO₂ removals/emissions from the 4B2 "Land Converted to Cropland" category there were calculated carbon stock in biomass (losses and increments) due to the conversion of land from natural conditions and other uses to cropland, including deforestation, conversion of pasture and grazing lands as well as perennial plantations to cropland etc. At the same time, estimates for this category also included N₂O emissions resulting from conversion of grassland to cropland.
