Carbon sink: plot a reports the evolution of the total forest C sink in the historical period (TOTAL Hist., until 2017; solid red line) and in the future, for both business-as-usual and VS scenario (TOTAL business-as-usual and TOTAL VS, until 2030; dashed red lines), further distinguished between living biomass, dead organic matter (DOM, including dead wood and litter) and soil. Plot b reports the historical (Hist., until 2017) and future (until 2030, under the business-as-usual and VS scenarios) total forest C sink including the HWP mitigation potential (assuming that the total amount of salvage logging is accounted as domestic production). All values are referred to the category Forest Land remaining Forest Land (FL-FL, as reported in (ISPRA 2019), equal to about 7932 kha in 2017, and reported in Gg CO₂ year⁻¹, with negative values highlighting removals from the atmosphere
