R² of 0.993 6 and a prediction interval confidence probability of 0.892 4， outperforming the comparison model. This model demonstrated significant practical value for papermaking industry.]]> 2025/2/25 13:04:29 HU Yusha,ZHOU Jianzhao 5true R² of the four different types of enterprises were all above 0.74. The carbon emission accounting model was used to conduct greenhouse gas emission accounting at the factory scale for the 112 paper enterprises in the list of key emission units in China. The results showed that there were significant differences in greenhouse gas emissions among the 112 key emission units in the paper industry. The minimum emission was 44 500 t CO₂eq， and the maximum emission reached 4 260 100 t CO₂eq. This method also provided a new idea for carbon emission accounting at the factory scale.]]> 2025/2/25 13:04:29 HU Song,LI Jigeng,HONG Mengna,HAN Yulin 4true 2025/2/25 13:04:29 LIANG Xiangyao,HE Zhenglei 3true 2025/2/25 13:04:30 KONG Lingbo,CHEN Liang 2true Pinus kesiya plantations was taken as an example， and the carbon cost of plantation harvesting was estimated， based on the CHARM model， combined with the characteristics of product production and consumption， and considering the factor of time. The results showed that the carbon cost of harvesting Pinus kesiya plantations was 4.2 to 16.6 tC/ha， confirming that harvesting activities cause carbon losses and providing a certain reference for further improving the current carbon footprint accounting methods for pulp， paper， and paper products in China.]]> 2025/2/25 13:04:30 AO Haolin,SU Zhenhua,LIU Zhenhua,SUN Bo,WAN Xiaofang 1true
