The carbon sink of boreal forests can be increased by paying forest landowners for carbon sequestration and taxing carbon releases. The aim of the study was to analyze the effect of carbon pricing on optimal forest management when forests are managed for maximal discounted benefits from timber production and carbon payments. A 0.5% random sample of all private forest stands of Finland was used in the analyses (48,842 stands). Calculations were performed for a 100-year time horizon. It was assumed that the carbon balance (difference between sequestrated carbon and released carbon) in the forest (trees and soil) or the carbon balance of forestry (trees, soil and wood-based products) was subsidized (positive balance) or taxed (negative balance) by 0, 50, 100 or 150 € t⁻¹, corresponding to CO₂ prices of 0, 13.6, 27.3 or 40.9 € t⁻¹, respectively. The results showed that paying forest landowners 150 € t⁻¹ of carbon sequestrated in forests would lead to the cessation of all cuttings everywhere in Finland for at least 100 years. In the northern part of the country, a carbon price of 100 € t⁻¹ would be enough to make the no-cutting management economically optimal. A low carbon price had the highest relative impact (value of increased sequestration divided by the cost of carbon payments). The benefit/cost ratio of carbon subsidies was higher in the northern part of boreal zone than in the southern parts. Subsidizing within-forest carbon sequestration by 50 € t⁻¹ would increase the carbon sequestration of Finnish forestry by 50%, ranging from 36% (south Finland) to 116% (north Finland). A payment of 100 € t⁻¹ or more would increase carbon sequestration by 70%, which is nearly the maximum possible increase that can be obtained by carbon subsidies.

可以通过向林地所有者支付固碳和征收碳排放税来增加北方森林的碳汇。该研究的目的是分析以木材生产和碳支付带来的最大折价收益来管理森林时，碳定价对最佳森林管理的影响。分析中使用了芬兰所有私人林分的0.5％随机样本（48,842个林分）。对100年的时间范围进行了计算。假定补贴了森林（树木和土壤）中的碳平衡（固存碳和释放的碳之间的差异）或林业的碳平衡（树木，土壤和木质产品）或征税了（负平衡）。余额）0，50，100或150€t ^-1，对应于CO ₂价格分别为0、13.6、27.3或40.9€t ^-1。结果表明，向森林所有者支付150欧元t ^-1的森林固存的碳将导致芬兰各地至少100年停止所有砍伐。在该国北部，100欧元t ^-1的碳价足以使无削减管理在经济上达到最佳。较低的碳价具有相对最大的影响（增加的固碳价值除以碳支付成本）。北方地区北部的碳补贴收益/成本比高于南部地区。向森林内部的碳固存提供50欧元t ^-1的补贴将使芬兰林业的碳固存增加50％，范围从36％（芬兰南部）到116％（芬兰北部）。支付100欧元t ^-1或更多的费用将使碳固存增加70％，这几乎是通过碳补贴可获得的最大可能的增加。
