Land Use, Land-use Change and Forestry covers the following categories; Forest land, Cropland, Grassland, Wetlands, Settlements, Other land and Harvested Wood products.
This sector is a net source of carbon in all years. This result is determined largely by the CO2 emissions from Grassland and Wetlands, due to drainage of organic soils, offset somewhat by Forest Land, which acts as a major carbon sink. Harvested Wood Products are a sink of carbon for all years. The complex dynamics of land-use changes between categories and the relative contributions from biomass and soils lead to fluctuating estimates of sectoral emissions and removals.
