Carbon stock in harvested wood products ( HWP) can effectively reduce the concentration of carbon dioxide in the atmosphere,which has been included in the national GHG inventories. From the national level,the disputes and coordination of the carbon accounting approaches and trade flows accounting approaches of HWP,which are based on theCommon but Differentiated Responsibility'( CBDR) principle,have impacts on the allocation of emission reduction responsibilities and the distributions of benefits on the parties'future climate change negotiations. This article first summarized the IPCC conferences which are relevant to HWP carbon stock accounting as well as the negotiation process,and reviewed the development process vertically. Second,it compared the application and disputes of accounting approaches in different countries and regions,and made a summary of the approaches' application and their related interests. Lastly,the different effects of Production Approach( PA) and Stock Change Approach( SCA) on the estimation of carbon storage in HWP were analyzed from the point of view of inventory report and international trade,and the applicable properties of the two methods were summarized. Results are as follows: ①During the second commitment period of the Kyoto Protocol( KP) ,AnnexⅠcountries should include the HWP carbon stock in the inventories. The parties should estimate the stock changes using PA if a party does not want to report their contribution of HWP as zero. And then estimating carbon stock change of HWP that are produced by domestic harvested wood becomes a basic requirement for the parties when it comes to mitigation responsibilities. ②From the perspective of reporting,AnnexⅠcountries are required to report the carbon stock of HWP at the forest management reference level. PA makes a distinguish from forest management activities and estimates carbon of HWP from sustainable forests,which is in compliance with the requirements of reporting. ③From the perspective of international trade,because of considering the carbon stock changes from HWP import and export,SCA is more beneficial to the largest trading countries such as China and other countries.
