全世界的重新造林项目数量正在增加。在许多情况下，资金是通过声称的树木碳捕获获得的，被称为即时和持久的，而重新造林的地块需要时间和维护才能实现其碳捕获潜力。此外，索赔通常忽略森林存在期间自然或人为干扰的环境成本，也不考虑与重新造林有关的温室气体排放。这项研究使用生命周期评估来量化在秘鲁亚马逊地区建立重新造林地块的碳足迹。同时，我们结合联合收割机土壤碳模型与地上和地下植物碳模型来预测种植后碳储量的增加。我们将我们的结果与一个重新造林平台提出的碳捕获声明进行了比较。我们的研究结果表明，在重新造林项目中，如果（1）忽略树木达到其碳捕获潜力所需的时间，（2）忽略建立地块所涉及的温室气体排放，（3）报告每棵树的碳捕获潜力，从而忽略森林生态系统水平的限制，那么碳核算就会出现重大错误。或（4）低估了由于不可避免的人为和气候干扰造成的树木损失。此外，我们表明，生物炭在造林过程中的应用可以部分补偿项目排放。
The number of reforestation projects worldwide is increasing. In many cases funding is obtained through the claimed carbon capture of the trees, presented as immediate and durable, whereas reforested plots need time and maintenance to realise their carbon capture potential. Further, claims usually overlook the environmental costs of natural or anthropogenic disturbances during the forest’s lifetime, and greenhouse gas (GHG) emissions associated with the reforestation are not allowed for. This study uses life cycle assessment to quantify the carbon footprint of setting up a reforestation plot in the Peruvian Amazon. In parallel, we combine a soil carbon model with an above- and below-ground plant carbon model to predict the increase in carbon stocks after planting. We compare our results with the carbon capture claims made by a reforestation platform. Our results show major errors in carbon accounting in reforestation projects if they (1) ignore the time needed for trees to reach their carbon capture potential; (2) ignore the GHG emissions involved in setting up a plot; (3) report the carbon capture potential per tree planted, thereby ignoring limitations at the forest ecosystem level; or (4) under-estimate tree losses due to inevitable human and climatic disturbances. Further, we show that applications of biochar during reforestation can partially compensate for project emissions.
