| Abstract:It is estimated that forest transformation and degradation caused by natural and anthropogenic disturbances account for approximately 20% of global greenhouse gas emissions, among which wood harvesting is the primary cause for the reduction in forest carbon stocks. Although most forests used for economic purposes are currently subject to “sustainable” forest management, such that the disturbance of wood harvesting activities on the carbon dynamics of these forests can be negligible, this practice of using the carbon benefits from new forest regrowth to offset the carbon losses caused by old logging is unjustifiable. Because this net carbon accounting method does not attribute any value to the carbon storage capacity of forest regrowth and unlogged forests. Hence, this paper presents the calculation results of a new method – taking the production of disposable hygiene products from Simao pine plantations as an example. Based on the CHARM model and in combination with the characteristics of product production and consumption, considering the factor of time, the carbon cost of logging in Simao pine plantations is calculated to be 4.2 - 16.6 tC/ha, confirming the actual carbon losses caused by logging，and providing a reference for further improving the carbon footprint calculation method for pulp, paper, and paper products in China. |
