中国是木质林产品的生产、消费和出口大国,分析其产品碳足迹的分布特征对于林产行业的国际贸易和节能减排工作具有重要意义。文章采用投入产出生命周期模型计算中国木质林产品的碳足迹,并对不同种类木质林产品产业链上的碳足迹分布进行分析。研究结果表明,产品碳足迹总量最大的木质林产品是木家具(占总量的36%),而单位产品碳足迹强度最大的木质林产品是纸制品(占整体的16%);针对林产品行业内部的产业链角度,碳足迹的主要流量发生在从用材林的种植和养护业到最终产品的制造;林产品产业行业外部,碳足迹的贡献则主要来自于金属冶炼及压延加工业、化石燃料开采业等行业,这2个行业碳足迹贡献分别占21%和18%;整体上,中国木质林产品生产中温室气体的排放以燃料燃烧产生的二氧化碳为主,这与产业链外其他行业的碳贡献密不可分。研究表明,通过碳足迹在产业链上的分布可以有助于分析林产品碳排放的工作重心。 China is a large country of production, consumption and export of wood-based forest products. Analyzing the distribution characteristics of its product carbon footprint is of great significance to international trade and energy conservation and emission reduction in the forest products industry. This paper uses the input-output life cycle model to calculate the carbon footprint of China’s wood-based forest products and analyzes the distribution of carbon footprint in the different types of wood-based forest products industry chain. The results show that the wood products with the largest total carbon footprint are wood furniture (36% of the total), and the wood products with the highest carbon footprint per unit product are paper products (16% of the total) Within the industry chain, the main flow of carbon footprint occurs from the planting and conservation of timber forests to the manufacture of final products. Outside the forest products industry, the contribution of carbon footprint mainly comes from the metal smelting and rolling processing industry, fossil Fuel extraction and other industries. The carbon footprint contribution of the two industries accounted for 21% and 18% respectively. On the whole, the emission of greenhouse gases from the production of China’s woody forest products is dominated by the carbon dioxide generated by fuel combustion. This is in line with other industries outside the industry chain The contribution of carbon is inseparable. Research shows that the distribution of carbon footprint across the industry chain can help to analyze the carbon emissions focus of forest products.
