PROJECTION OF GLOBAL LONG-TERM CARBON FLOW IN THE FOREST PRODUCTS TRADE FROM A CLIMATE NEGOTIATION PERSPECTIVE: 2010-2030

摘要

Forest products exhibit natural carbon-storage functions and alternative emission effects necessary to mitigate climate change effectively. Carbon flow, which is generated along with forest products trade, has been considered as an important topic of inter-governmental climate negotiations and distribution of climate responsibilities. Based on a case study of harvested wood products (HWP), the Global Forest Products Model (GFPM) and stock change approach were used in this research to simulate and analyze regional and national carbon flow in the trade from 2010 to 2030. Results show that Europe, Asia, and North/Central America are the major regions of such a carbon flow in the world; their corresponding total trade carbon flow will reach upto 75.9, 43.0, and 33.0 Tg C by 2030, respectively. Among these regions, Europe and Asia are the largest and most principal net outflow and inflow regions, respectively; the corresponding net carbon flows will reach 28.2 and 17.3 Tg C by 2030, respectively. Developed countries will remain in a dominant position in the carbon flow of HWP trade from 2010 to 2030, and will be net carbon outflow countries in HWP trade. By contrast, developing countries will be accounted for the net inflow in the carbon flow of HWP trade. Gross trade carbon flow and net trade carbon flow of both groups are likely to be exhibited as an increasing trend. In terms of product structure of HWP trade carbon flow, developed countries will focus on exporting sawnwood with higher carbon-storage performance, and on importing paper and paper-board with lower carbon-storage performance. Developing countries will experience completely opposite circumstances. However, product structure greatly differs among these countries.
