The use of wood products is often promoted as a climate change mitigation option to reduce atmospheric carbon dioxide concentrations. In previous literature, we identified longevity and recycling rate as two determining factors that influence the carbon stock in wood products, but no studies have predicted the effect of improved wood use on carbon storage over time. In this study, we aimed at evaluating changes in the lifespan and the recycling rate as two options for enhancing carbon stock in wood products for different time horizons. We first explored the behaviour over time of both factors in a theoretical simulation, and then calculated their effect for the European wood sector of the future. The theoretical simulation shows that the carbon stock in wood products increases linearly when increasing the average lifespan of wood products and exponentially when improving the recycling rate. The emissions savings under the current use of wood products in Europe in 2030 were estimated at 57.65 Mt carbon dioxide (CO2) per year. This amount could be increased 5 Mt CO2 if average lifespan increased 19.54 % or if recycling rate increased 20.92 % in 2017. However, the combination of both strategies could increase the emissions saving almost 5 Mt CO2 more by 2030. Incrementing recycling rate of paper and paperboard is the best short-term strategy (2030) to reduce emissions, but elongating average lifespan of wood-based panels is a better strategy for longer term periods (2046).

从理论模型到欧洲木业应用的增加,使用寿命和回收率对木制品中碳存储的影响。

通常提倡使用木制品作为减轻气候变化的选择,以减少大气中的二氧化碳浓度。在以前的文献中,我们将寿命和回收率确定为影响木材产品中碳储量的两个决定性因素,但没有研究预测随着时间的推移,木材使用量的增加对碳储量的影响。在这项研究中,我们旨在评估寿命和回收率的变化,将其作为在不同时间段内增强木制品碳储量的两种选择。我们首先在理论模拟中探讨了这两个因素随时间的行为,然后计算了它们对未来欧洲木材业的影响。理论模拟表明,木材产品中的碳储量在增加木材产品的平均寿命时呈线性增长,而在提高回收率时呈指数增长。据估计,到2030年,欧洲目前使用木制品的排放量将节省57.65吨二氧化碳(CO2)每年。如果2017年平均寿命增加19.54%或回收率增加20.92%,则该数量可以增加5 Mt CO 2。但是,这两种策略的结合可以在2030年之前将排放量节省近5 Mt CO 2。纸和纸板是减少排放的最佳短期策略(2030),但延长人造板的平均寿命是长期的更好策略(2046)。
