This study is aimed at developing a supply-demand model of wood products, and outlook for mid-term and long-term supply and demand for each products. The main wood products include sawnwood, plywood, particle board, fiberboard (MDF), and pulp. The partial equilibrium model is composed of supply function, import demand function, demand function, price relation function. With given parameters the outlook for year 2050 says that sawnwood, plywood, and fiberboard for domestic productions and imports are decreased. This may result from the increase of log prices from the inside and outside of the country because of the propensity for environment protection and the resource nationalism. On the other hand the supply of particle board and pulp will increase because they are made from wasted wood and chips.

This study analyzed core issues addressed in the tentative agreement of WTO ministerial meetings held to finish WTO/DDA negotiations in Geneva in July 2008. The objectives of this study are to analyze changes in tariff reduction on timber products, and their influence on demand and supply of the items according to the modality of Non-Agricultural Market Access (NAMA) and to provide basic information for strategy formulation of our country for further WTO/DDA negotiations. The results indicate that there will not be significant changes in the tariff on sawnwood and on veneer sheets, however, the tariff on plywood need to be cut by around 50% from the applicable tariff rates of 2008 on condition that our country is in the position of developed countries. Therefore, the item of plywood is expected to be influenced greatly according to the change in tariff reduction. From the analysis of influence of tariff reduction on the demand and supply of timber products including sawnwood and wood based panels, such as plywood, particleboard, and fiberboard, the import quantities of the items are expected to be changed from 0.8% to 13.3% if our country is in the position of developed countries, however, they are expected to decline by 0.8%~44.3%, if our country is in the position of developing countries (22, coefficient for developing members).

This study was analyzed the changes of the tariff reduction for the timber products according to the modalities proposed by the chairman of Non-agriculture Market Access. The resulted data would be expected to be used for establishing the strategies for the WTO/DDA negotiation of Korea. As WTO/DDA negotiation was officially resumed in the early 2007. It was necessarily required to develop a strategy how to address debating core issues raised during the negotiation since 2006. For this purpose, major core issues and agenda were arranged and analyzed in this study. In Korea, the results of the analysis show that, in the position of developed members, the applicable tariff rates after the tariff reduction of sawnwood and veneer sheet was not different from that in 2007. However, in the position of developing members, the applicable tariff rate of sawnwood and veneer sheet was increased after the tariff reduction. The unbound tariff lines, wood-based panels such as plywood and medium-density fiberboard, the applicable tariff rate after the tariff reduction was analyzed to be reduced more than 50% in the position of developed members, and therefore is determined to be considerable influenced upon the applicable tariff rates. On the other hand, in the position of developing country the tariff rates after the tariff reduction was higher than that of the applicable tariff rates in 2007. Thus no changes of the tariff reduction by a negotiation agreement was analyzed to be happened.

This study was carried out to quantify degree of contribution of harvested wood product (HWP) on mitigation of climate change by valuation of public benefits, environmentally and economically. The potential carbon dioxide emission reduction of HWP was estimated by accounting carbon storage effect and substitution effect. Based on 2014 statistics of Korea Forest Service, domestic HWPs were sorted by two categories, such as wood products produced domestically from domestic and imported roundwood. The wood products were divided into seven items; sawnwood, plywood, particle board, fiberboard (MDF), paper (including pulp), biomass (wood pellet) and other products. The carbon stock of wood products and substitution effects during manufacturing process was evaluated by items. Based on the relevant carbon emission factor and life cycle analysis, the amount of carbon dioxide emission per unit volume on HWP was quantified. The amounts of carbon stock of HWP produced from domestic and from imported roundwood were 3.8 million $tCO_{2eq}$., and 2.6 million $tCO_{2eq}$., respectively. Also, each reduction of carbon emission by substitution effect of HWP produced from domestic and imported roundwood was 3.1 million $tCO_{2eq}$. and 2.1 million $tCO_{2eq}$., respectively. The results of this study, the amount of carbon emission reduction of HWP, can be effectively used as a basic data for promotion of wood utilization to revise and establish new wood utilization promotion policy such as 'forest carbon offset scheme', and 'carbon storage labeling system of HWP'.

Recommendaton: These are the highlights of the findings of the Timber Consumption Survey carried out by the Project in 1966, and covering consumption for the period from 1961 to 1965. The survey was oriented towards consumption for structural, commercial and industrial purposes and existing estimates for local (village-level) consumption as fuel and the like were adopted. A full report on the survey was submitted to the Bureau of Forestry in 1966. Long-term Trends: After allowance for anticipated population increase, this ten year's increase in industrial wood consumption represents a gain of about 30% in per capita consumption (from 0.0913 cu.m. per capita to 0.118 cu.m. per capita). This is only about half the expected general economic growth of about 75% (7% per annum). It is therefore likely (a) that the 1975 estimate is conservative, (b) that the consumption demand beyond 1975 may be expected to build up at a greatly increased rate. Estimated income elasticity coefficients are high, and with expected ir,creases in prosperity and population, the consumption is expected to rise to 10 million cu. meters by the year 2,000. Consumption Pattern: The breakdown of industrial consumption (1965) is given in Table 4-2, showing sawnwood consumption as the most important in 1965. The upward trend in all sectors over the 1961-65 period is expected to continue. The general consumption pattern is expected to change through 1975 with a sharp increase in the relative importance of pulp products (to 30% of total consumption) offset by declining relative importance of sawlogs. The following recommendations follow from the study: (i) Industrial forests. - A programme of establishment of consolidated industrial forests should be initiated as a matter of urgency. (ii) Fuelwood forests - Properly sited, protected and managed fuelwood forest, worked on a 20-year rotation, should be established as a nation wide basis. (iii) Hardwood utilization - Detailed investigations are required into the use of indigenous hardwoods for the pulp, particle board and hardboard industries. (iv) Mining timber - Preservation treatment of all mining timber should be enforced by law. (v) Sawmills - Licencing restrictions should be enforced to reduce the number of small, inefficient sawmills. b. Extension work should be undertaken bv government to improve sawmilling practices.

This study aims to update the supply-demand model of wood products(FOSMO-2013) and to forecast mid and long run supply and demand for each products. The subjects of the study include sawnwood, plywood, particle board, fiberboard(MDF), and pulp. The updated partial equilibrium model is composed of supply function, import demand function, demand function, price relation function. The long run outlooks of world prices of wood and wood products are imported from the results of Buongiorno(2012). This study also adopt Buongiorno's scenarios, which includes three scenarios of IPCC(A1B, A2, B2) and the other one with assumption of increasing fuelwood consumption of A1B scenario. The result says that the domestic productions of wood products are expecting to decrease while the imports of them increase even there are some differences among the products as well as scenarios.

This study estimated the amount of carbon stocks in harvested wood products (HWP) using accounting approaches suggested by 2006 IPCC guidelines and analyzed the impacts of different approaches on national greenhouse gas inventory and the forest sector in Korea. The change in carbon stocks was calculated at the level of semi-finished wood products, which cover sawnwood, wood-based panels, other industrial wood, paper and paperboard. An estimation of the changes in carbon stocks in HWP in use for the period 1970~2008 varied between -9,023 Gg $CO_2$/yr and 4,052 Gg $CO_2$/yr depending on the accounting approach used. The stock-change approach provided the most favorable results because Korea was a net importer of wood products. However, each approach generates different impacts on harvest, trade, the use of wood for energy production and recycling. When deciding its position on accounting approach, thus, the Government should consider future direction of national forest policies as well as the effect on national greenhouse gas inventory for the minimization of negative impacts resulting from its selection.
