Research Progress in Carbon Footprint Calculation Methods for Wooden Products
Wooden products are products processed with wood as the main materials,and the carbon footprint of wooden product is the total greenhouse gas emissions from the product system.Conducting product carbon footprint accounting is an inevitable step to reduce product emission and break through the carbon duty.The existing research on the carbon footprint of wooden products often focuses on empirical accounting for carbon footprint,and in-depth analysis of carbon footprint accounting methods is yet to be studied.On the basis of summarizing the calculation methods of carbon footprint,this paper analyzes the carbon footprint of wooden products under the two system boundaries of"cradle to gate"and"cradle to grave".Aiming at carbon footprint calculation in the future,three suggestions are proposed:1)Integrating carbon storage into the research on carbon footprint of wooden products on the basis of complying with the ISO 14067 and PAS 2050 on carbon footprint accounting standards and in view of the carbon storage characteristics of wooden products;2)Carrying out the in-depth research on the raw material and production subsystems of products and refining the research units,to obtain and accumulate as much real-life data as possible,and establish the database of carbon emissions that conforms to the characteristics of raw materials,equipment,and processes in China;and 3)Conducting the study of the carbon footprint of wooden products based on"cradle to grave"system boundary,and building a carbon storage measurement model for the entire life cycle of wooden products by comprehensively considering parameters such as processing loss,use,disposal,and recovery,so as to calculate the contribution of carbon storage of wooden products to the carbon footprint throughout the entire life cycle.
