Timber can mitigate climate change because it can store carbon for decades. However, the value of timber carbon stocks has been neglected for a long time, which has led to overemphasize the production yields of timber. This approach is detrimental to increasing forest carbon sinks. Therefore, quantifying the economic value of the timber carbon stocks and incorporating it into timber prices have great practical significance for sustainable forest development and climate change mitigation. Moreover, the leakage of the global timber carbon stock value (TCSV) is prominent, and the flow patterns of the global trade-embodied TCSV should be determined to precisely evaluate the forest assets of individual economies. Based on the Exiobase database and a multi-regional input-output model, this study calculated the TCSV of 43 economies and 5 regions from 1995-2011 considering the cross-border transfer of TCSV. Furthermore, the effects of incorporating TCSV into timber prices on various product prices were explored. The results show that the top 10 surplus economies regarding the accumulated TCSV between 1995 and 2011 are the major contributors of production-based timber carbon stock value, and the top 10 deficit economies are dominated by developed economies with large net import-embodied TCSV. The ripple effect of the rising price of timber caused by TCSV as an environmental cost mainly influenced harvested wood products and energy-fuel products. The research findings provide a scientific assessment of the TCSV and contribute to advancing the timber pricing mechanism to increase forest carbon sinks.

木材可以缓解气候变化，因为它可以储存数十年的碳。但是，木材碳储量的价值长期以来一直被忽略，这导致过分强调木材的产量。这种方法不利于增加森林碳汇。因此，量化木材碳储量的经济价值并将其纳入木材价格对于森林可持续发展和减缓气候变化具有重要的现实意义。此外，全球木材碳储量价值（TCSV）的泄漏非常突出，应确定全球贸易性TCSV的流动模式，以准确评估各个经济体的森林资产。基于Exiobase数据库和多区域输入输出模型，该研究计算了1995-2011年43个经济体和5个地区的TCSV，其中考虑了TCSV的跨境转移。此外，还探讨了将TCSV纳入木材价格对各种产品价格的影响。结果表明，在1995年至2011年之间，按累积的TCSV计的前十大顺差经济体是基于生产的木材碳储量价值的主要贡献者，而前十个赤字经济体则由具有大量净进口TCSV的发达经济体所主导。TCSV作为环境成本引起的木材价格上涨的连锁反应主要影响了伐木产品和能源燃料产品。研究结果为TCSV提供了科学评估，并有助于推进木材定价机制以增加森林碳汇。
