Estimates of forest biomass and soil carbon sequestration in Finland and Norway during the past two decades are 8 and 5.6 Tg C yr1, respectively, or 39 and 46 g C nr2 yr1 (Liski et al. For Sweden, forest carbon accumulation between 1920 and 2000 was estimated to be 7.1 Tg C yr1, or 31 g C m-2 yr1 (Agren et al. The soil carbon sink was about 19% to 28% of the total carbon sink, estimated using models.
