Carbon efficiencies of energy production (Mt C sequestered per Mtoe produced) for the three intensification scenarios separately (D, O_v, and M) and all three scenarios combined (D + O_v + M) between 2010 and 2115. Carbon efficiencies were calculated as cumulated total carbon balance (Mt C) divided by cumulated energy production (Mtoe). Blue shows all three scenarios combined (D + O_v + M), brown shows intensification of actively managed sites (M), red shows intensification of harvest-delayed sites (D), green shows intensification of overstocked sites (O_v), and black shows business as usual management of all sites (BaU). The intensification scenarios are presented in section “Methods”—Intensifying forest management and summarized in Table 3
