  1. For all datasets, values include above and below ground carbon. Secondary forests are further disaggregated by forest-age classes. This shows the average removal value for each biome, which in the National Greenhouse Gas Inventory (NGHGI) [38] varies according to the type of land use transition taking place, and in the Global Earth Observation (EO) [17] varies depending on the type of forest plantation. The calculated modal removal factor in each biome for the Global EO dataset (see “Methodology”) is shown. Values in brackets indicate removal factors also used but where the associated ecozone did not account for a large area within the biome
