Emissions caused by deforestation are determined following IPCC (2006), by multiplying the Acitivity Data with the Emission Factor for gross deforestation (the average carbon stock of the forest in t C per ha). While more detailed carbon stocks for other land use types need to be determined, it was assumed that the carbon stock after deforestation is zero. This is because most of the deforestation was caused by all mining (69%), urban (3%) and infrastructure (18%) (SBB, 2021), which are land use classes corresponding to a carbon stock of zero.

Forest degradation is for the second FREL (2021) defined as “human-induced or natural loss of the goods and services, provided by the forest land, in particular the forest carbon stocks, not qualifying as deforestation, over a determined period of time”.
Forest degradation is only temporary, with the forest expected to recover after a certain period of time, such as is the case for logging and shifting cultivation. The above mentioned goods and services refer to a holistic approach that includes a broad spectrum of aspects such as maintaining biodiversity and hydrological functions.
In the table and graphs you will find data of emissions from deforestation and forest degradation, caused by activities from industrial roundwood, fuelwood and first to shifting cultivation.
