Albedo and CO₂ sequestration are the two most important climate forcing factors in forestry. After harvest the albedo in boreal forests increases which has a cooling effect. Likewise, CO₂ captured in the photosynthesis reduce atmospheric CO₂ and thereby have a cooling effect. These effects have value to society, and they may affect optimal management.

This article investigates the effect on economical optimal forest management – here the optimal harvest age – by payment for these forcers. The albedo effect is evaluated using the standard climate metric global warming potential (GWP) with a time horizon of 100 years, i.e. in terms of CO₂ equivalents. Alternative measures are discussed. The cooling effect of albedo change at time of harvest for the total Norwegian harvest corresponds to about 1.3% of the current Norwegian GHG emissions. The variation in albedo effect across the southern part of the country is modest.

The CO₂ sequestration effect is much larger than the albedo. At the time of harvest the CO₂ content in forest is more than 40 times the albedo effect. The carbon effect will therefore dominate the effect on the harvest age. Payments for climate services will prolong the rotation period. With the current quota price in the EU ETS – about 80 € ton⁻¹ CO₂ equivalents – and current stumpage value, carbon capture and storage will be more profitable than commercial timber production for young stands. For stands close to maturity, the payment scheme will have little effect.

反照率和CO ₂封存是林业中两个最重要的气候强迫因素。收获后，北方森林的反照率增加，具有降温效果。同样，在光合作用中捕获的CO _{2会减少大气中的 CO 2}并因此具有冷却效果。这些影响对社会具有价值，它们可能会影响最佳管理。

本文研究了通过支付这些强制人员对经济最优森林管理（此处为最佳采伐年龄）的影响。使用时间跨度为 100 年的标准气候度量全球变暖潜能值 (GWP) 评估反照率效应，即以 CO ₂当量计。讨论了替代措施。挪威总收获时反照率变化的冷却效应相当于挪威目前温室气体排放量的约 1.3%。该国南部地区的反照率效应变化不大。

CO ₂封存效应远大于反照率。采伐时森林中的CO ₂含量是反照率效应的40多倍。因此，碳效应将主导对收获年龄的影响。气候服务付费将延长轮换期。鉴于目前欧盟排放交易体系中的配额价格（约 80 欧元吨^-1 CO ₂当量）和目前的立木价值，碳捕获和储存将比用于幼林的商业木材生产更有利可图。对于接近到期的展位，支付计划的影响不大。
