中国木质林产品贸易的碳流动--基于气候谈判的视角

Carbon Flow of Chinese International Trade of Forest Products: Based on the Climate Change Negotiations

木质林产品(下简称HWP)国际贸易的碳计量和分配问题是《联合国气候变化框架公约》HWP议题谈判的焦点。依据IPCC指南,核算1961—2011年我国木质林产品贸易的碳储量和碳排放,继而分析木质林产品贸易的碳流动对减排贡献的影响。结果表明:我国木质林产品贸易的碳储量流动不断增长,应用不同的IPCC碳量核算方法会对附件I贸易国的碳减排产生不同影响。木质林产品进口提高了储量变化法核算的碳清除贡献;运用大气流动法,我国木质林产品的贸易与使用已成为碳排放源。

The measurement and allocation of carbon in harvested wood products （HWP） of international trade is an important forestry issue in the United Nations Framework on Climate Change Convention. In this paper, the carbon storage and carbon emissions of HWP in trade for China was accounted from 1961--2011, then the contribution to carbon removal was analyzed according to the IPCC guidelines. Research showed that： The carbon flow accounted by different method suggested by IPCC had different effect on carbon reduction for annex I trading nation. The carbon stock in the form of wood product imports grew constantly, which had increased carbon removal by stock-change approach. While estimated by atmospheric-flow approach, large imports of primary wood materials increased carbon emissions, so that trade of HWP had made China become a ＂ carbon source＂.
