Net forest-related greenhouses gas flux represents the net exchange of greenhouses gas between forests and the atmosphere between 2001 and 2020. This net flux layer is part of the forest carbon flux model described in Harris et al. (2021). Here, the average annual net fluxes in MtCO₂e is shown at global level and the average annual net fluxes in MtCO₂e/ha in protected areas and outside protected areas at national level.
