Annual carbon stock change in Mt C by forest management (excluding afforestation, reforestation and deforestation, ARD). Indications from 1990 until 2007 based on IEEAF data and from 2003 until 2040 based on different WEHAM scenarios. The values in 2003 – 2007 reflect a mean between IEEAF and the respective WEHAM scenario. The NIR indicates the officially reported figures to IPCC (extrapolation on constant level). Positive (black) numbers represent emissions to the atmosphere; negative (red) numbers represent removals from the atmosphere (the sink function of forests).
