助力"碳中和":中国木质林产品碳储量测算与增长路径
Supporting carbon neutrality:estimation and growth pathways of China's harvested wood products carbon stock
摘要
Abstract
[Objective]In the context of China's dual carbon goals,this study aims to examine the carbon sequestration capacity and potential growth pathways of harvested wood products(HWP),with the intention of contributing to international climate negotiations and the achievement of carbon neutrality targets.[Method]Based on a comprehensive review of carbon accounting methods for HWP under the Intergovernmental Panel on Climate Change(IPCC)guidelines,this study adopted the revised Production Approach outlined in the 2019 IPCC guidelines.Using this method,the carbon stock contribution of HWP in China from 1961 to 2022 was calculated.Furthermore,the study analyzed key model parameters and accounting rules to propose feasible pathways for enhancing carbon sequestration.[Result](1)The cumulative carbon stock of China's HWP reached 751.41 Mt by 2022,with sawnwood,wood-based panels,and paper products accounting for 269.04,404.96 and 77.41 Mt,respectively.(2)In 2021,the annual increase in HWP carbon stock offset approximately 1.4％of China's net carbon emissions from energy consumption.Within the forestry sector,the carbon storage of HWP balanced its carbon emissions,achieving sectoral"carbon neutrality".(3)Under the calculation framework of the revised Production Approach,an increase in paper recycling rates led to greater carbon stock in paper products.However,rising imports of industrial roundwood and exports of semi-finished wood products resulted in a net loss of domestic carbon stock.[Conclusion]China's HWP carbon stock has reached a substantial level and still possesses considerable growth potential.It can effectively support the realization of carbon neutrality goals and should be recognized as a significant asset in climate negotiations.Future efforts should focus on enhancing the recycling efficiency of paper,strengthening domestic wood supply and reserves,and promoting the export of finished wood products to further increase domestic HWP carbon sequestration.关键词
