The purpose of this study is to estimate the optimal tax rate for gasoline in Korea, by utilizing both the parameters for the estimation of the optimal fuel taxes and the theoretical model considering externalities proposed by Parry and Small (2005). The result of simulation shows that the optimum fuel taxes in Korea is calculated in 382 korean won per liter, which is lower than fuel tax rate(529 korean won per liter) currently being imposed. The fuel tax is composed of two types of tax. First is Pigouvian tax caused by negative externality such as traffic congestion and accidents etc. And second is Ramsey tax for optimal commodity sales taxes. We find that Pigouvian tax in Korea is higher than one of U.S. and U.K and Ramsey tax is very small due to the inelastic labor supply comparing to consumption elasticity of fuel. When adjusting the elasticity of labor supply to the UK level, the optimal fuel tax in Korea is very close to the current level of 480 korean won per liter. This paper contributes to suggest the reasonable estimation and discussion in the social optimum fuel tax rates by utilizing the theory and simulation and improve the possibility of the derivation of optimum fuel taxes through both securing the exact parameters and modifying the theoretical model suitable for Korea.

Currently, the tax - exempted vessel fuel is provided for commercial fishing in order to increase the competitive power of fishery production thorough the National Federation of Fisheries Cooperatives. The National Federation of Fisheries Cooperatives should predict the exact amount of fuel consumption for fishing every year to request the fuel from the government. Unfortunately, there is no sophisticated model to predict the tax - exempted vessel fuel consumption. In 2003, the consumption of the tax- exempted vessel fuel was only $25.1\%$ of the estimation amount by the National Federation of Fisheries Cooperatives. This causes an inefficiency in the petroleum management. Moreover, we need some data such as the annual average fishing hours, fishing days and fishing behavior to adopt a new policy regarding fishing. Up to now, the data have been obtained by survey with response in the fishery field. In the most case, we have a small number of data because we spend so much time and money consuming for collecting fishing data. As a result, the level of confidence of the data is associated with the sample size and normally low. In order to achieve more accurate data, we need to develope an efficient method for collecting fishing data. In this research, we proposed a new method to predict the tax- exempted vessel fuel consumption more exactly. The prediction results from the proposed method has been compared with the results from the current method. According to the results in this research, the method proposed here produced much better accuracy than the current method. In addition, we also proposed in the paper for collecting fishing data of the annual average fishing hours using the tax - exempted vessel fuel consumption and the gasoline consumption of vessel engine. The fishing data obtained by using the method proposed in this research could be much more efficient and accurate because it doesn't need to estimate from survey sample data.

In Korea, nuclear power plants are major sources of electricity supply with relatively low costs. Despite the importance and scale of nuclear electricity generation, the Korean tax and levy system is less organized than those in other countries, such as France and Japan, where nuclear power plants also play significant roles for electricity supply. Countries impose tax on nuclear electricity generation roughly in three ways: tax on nuclear reactors; tax on uranium fuel; tax on electricity from nuclear power plants. The Korean government may consider taxing nuclear electricity generation based on uranium fuel or electricity generation. If taxing on uranium fuel at the rate of 90 KRW per milligram of uranium, the Korean government can collect additional tax revenue of 430 billion KRW. If taxing on electricity from nuclear power plants at the rate of 11 KRW per kilowatt-hour, the government can collect additional tax revenue of 1,600 billion KRW.

After individual consumption tax on bituminous coal has been imposed by Korean government after 2014 Jul, we analyse the influence of tax and conclude that the consumption of high calorie coal has been increased and that of low/middle calorie coal has been decreased. And also, the average calorie of coal consumption has been increased and the more fuel cost happens on account of the average calorie increase. Those effects have been caused by the current tax imposition system which does not reflect the bituminous coal trait. The motivation of oversea resource development and the effort of coal blending skill have been decreased because of the current tax policy. We suggest 2 ways of the tax policy improvement system[1. tax imposition system in proportion to 5,000kcal/kg, 2. 15 stages(1 stage : 200kcal/kg) segmentation tax imposition system equal to the tax/(5,000kcal/kg)] to increase the current tax amount, to prevent the coal consumption distortion and to remove the further fuel cost.

This paper estimates the effects of imaginary repeated increases in excise duties on fuel oil consumption and on their income redistribution according to changes in consumer price index, if the inflation indexation system was introduced right after the second Energy Tax Reform ended in July, 2007 in Korea. In fact, nominal excise rates have not been adjusted since 2007. As a result, the real excise rates on fuel oils have been diminished inversely proportional to the consumer price index. Own- and cross-price elasticities of fuel oils such as gasoline and diesel oil are estimated under the general equilibrium framework based on the linear expenditure system. Counterfactual analyses through microsimulation in a static model are adopted to estimate the effects of introducing inflation indexation into the fuel tax in 2007 when the second Energy Tax reform ended on the fuel consumption and income redistribution in 2014. Microsimulations suggest that its introduction could have reduced the consumption of gasoline and diesel oil by 8.8% and 5.4%, respectively, ending up with increased excise revenue by 11.9%. The revenue increase in spite of decreased consumption is mainly because their demands are price inelastic. It could also have increased positive income redistributive effect by 0.01%p (from 0.12% to 0.13%), which is measured in terms of percentage decrease in Gini coefficient. In other words, the fuel excise on the two fuel oils decreased by 0.13% the Gini coefficient of before and after fuel tax income in 2014. This implies that the inflation indexation could have enlarged the income redistributive effect up to 0.13% in 2014, if it is introduced in 2007.

The tax exemption oil for fishery is expecting that the use of oil is gradually decreasing according to the environmental change such as reductions of vessel force caused by an upswing of oil prices and reduction of fishing vessels in the recent. Such reductions in the tax exemption oil amount have a negative effect on the tax exemption oil business and the fishery infrastructure. This paper studied to provide the basic data for a stable supply thorough the facts affected in the use of the tax exemption oil and the prediction for the use of the tax exemption oil in future. This analysis drew a estimation method by Cochrane-Orcutt repeated proceeding model with an object main factors such as a price of tax exemption oil and vessel force and international oil prices and exchange rates. And this analysis also drew the use of a tax exemption oil by 2000 after set up the scenario using an estimation method drawn. For the use of the estimated tax exemption oil analyzed to decrease within about 81 percent of the present(2020), It should be considering a stability plan for tax exemption oil for fishery in future.

The purpose of this paper is to come up with the measures for sustainable development of the agricultural sector in store for the strengthened U.N. Framework Convention on Climate Change. We analyze the spillover effects of Methane and Nitrous Oxides taxes (carbon tax) on the Korean agricultural sector. Unlike the other sectors, the agricultural sector has a unique characteristic generating greenhouse gas in the process of production itself even without consuming much fossil fuel. In order to estimate the impacts of those taxes, non-linear optimization method has been used with various assumed scenarios. The production effect, income and' price effect, and greenhouse gas emission reduction effect in the agricultural sector have been estimated through this method. The empirical results show that the paddy sector has a bigger tax effect than the livestock sector. In the paddy sector, the carbon tax has more impacts in the suburban areas than in the rural areas, while the swine farming section in the livestock sector has a conspicuous income effect in the midst of low greenhouse gas emission effect. These results allude us to apply graded tax rates to the crop, the livestock, and the region of different kind. Even if the agricultural sector has a less tax effect when compared with other industrial sectors, an environmental tax might be an effective measure to prevent global warming.

Since the Kyoto Protocol was released in 2005, there has been a number of mechanisms about funding and how to allocate the burdens. The UNFCCC(United Nations Framework Convention on Climate Change)have discussed establishing an international fund to support the reduction of a greenhouse gas. As the availability of adaption finance for developing countries increase, it's needed for a way of prioritizing countries. This article analyzes the carbon reduction system that includes a emission trading scheme, a carbon tax and examines GCF(Green Climate Fund)'s role and needs. A solution to finance Green Climate Fund is more preferred a harmonized carbon tax that across all nations with carbon tax. Especially the role of industrialized countries is important that based on their historical responsibility for fossil fuel emission. That is, they should get more shares of the global costs than developing countries.

KOGAS(Korea Gas Corporation) uses two-type vaporizers to send customers natural gas with imported LNG. In winter season, SMVs(SubMerged combustion Vaporizers) are mainly operated due to low seawater temperature. SMVs consume the natural gas of 1,520 $Nm^3/hr$ and emit a lot of $CO_2$ in winter time. If carbon taxes are activated on climate change, the tax burden will be severely heavy. Accordingly this work carried out numerical simulation with a commercail CFX code to investigate its possibility on the practical use of pure oxygen combustion of SMVs to reduce $CO_2$ and to improve its efficiency. First, a nozzle of a SMV's combustor is modelled. The combustion characteristics of Air/Fuel and Oxygen/Fuel are analyzed under folly insulated condition. Although we couldn't find the carbon reduction and the efficient elevation when the pure oxygen/fuel type was compared to the existing air/fuel one, we need a further study to investigate the effect of $CO_2$ recirculation.
