In this paper, we empirically analyzed whether carbon leakage really happened in EU by comparing before and after the period of EU ETS. We regarded foreign direct investment outflows as indicator of carbon leakage and analyzed panel regression between production cost including environment cost and this FDI variable. Also we consider foreign market potential to analyze market oriented FDI. According to this analysis, carbon leakage was observed in some models for manufacturing industry. However carbon leakage did not prove consistently in a variety of models and it is hard to speak carbon leakage was happened in EU ETS. Notwithstanding relatively short time series of data, in the view of the fact that carbon leakage was tested in some models, Korea also should keep in mind the possibility of carbon leakage and design emission trading scheme.

국내 자발적 탄소시장을 육성하고 성공적으로 정착시키기 위해서는 일본, 영국 등의 사례를 분석하여 시행착오를 최소화시킬 수 있는 최적의 시스템을 구축하는 것이 무엇보다 중요하다고 할 수 있다. 이를 위해서는 정부의 정책 및 의지가 가장 중요하다고 할 수 있으나 기업 및 기관들의 역할도 이에 못지않게 중요하다. 또한 국내 자발적 탄소시장의 규모를 확대하고 국제시장에서 배출권에 대한 신뢰도를 제고하기 위해서는 금융기관의 적극적인 참여도 필수적이라고 할 수 있다. 결과적으로 국내 자발적 탄소시장을 확대하기 위해서는 정부, 참여기업, 금융기관이 유기적으로 공조해야 할 것으로 보인다.

An aim of this paper is to test four hypotheses on price volatility in the $CO_2$ emission markets focusing on European Climate Exchange(ECX) in the EU Emission Trading Schemes(EU ETS) and Chicago Climate Exchange(CCX). I expect that, due to an influx of market information, a differently designed exchange market would bring a different price volatility, and various types of emission permits in the same exchange market would result in the same effects on the price volatility. Major findings are that the price volatility is same regardless of the types of emission exchange markets and emission permits comparing the rate of returns. However, comparing the GARCH variance, the volatility between ECX EUAs and CCX-CFIs and the volatility between EUAs(CERs) futures and daily futures are different with the exception of the volatility between EUAs futures and CERs futures. In conclusion, the price volatility depends on the types of exchanges and the types of emission permits.

We analyze the optimal hedge ratio and hedge effectiveness with different periodic times between spot and futures on EUA and CER based on EU-ETS. The Main finding are as follows. The first, hedging model which considers the time-varying variance is not more accurate than non-time-varying hedging models. The second, optimal hedge ratios are different even though hedge effectiveness is similar for the hedging purpose. The third, hedge effectiveness has uncertainty if hedge period is short. In case of EUA it needs to over 6 weeks and CER needs to over 7 weeks. The fourth, cross hedge with CER futures is not suitable for profit ratios.

This paper proposes a Cournot model that can be used to analyze the strategic behaviors of generation companies which try to maximize their profits in an imperfectly competitive electricity and carbon markets. The proposed model consists of two parts. First, the strategic behaviors of generation companies are modeled based on the Cournot theory. Second, the market operation is modeled based on the assumption that the market operator tries to maximize the total social welfare in consideration of environmental welfare. To find the Nash equilibrium of the proposed model, the two-level optimization technique is used. The proposed method has been applied to an illustrative example of oligopolistic markets. We found that the proposed method has strong potential to analyze the influence of the strategic biddings of the generation companies and the impact of renewable generator on markets where the competitiveness of the markets is not fully developed.

Emission trading schemes, exemplified by the EU Emission Trading Scheme, have been playing active roles in mitigating greenhouse gas emissions since the Kyoto Protocol employed an emission trading as one of the cost-effective mechanisms. The objective of this study is to investigate potential integration of forestry offsets in designing an emission trading scheme in South Korea. First, the study found feasible scopes in which forestry sectors can take part by analyzing five emission trading schemes: EU Emission Trading Scheme, Chicago Climate Exchange, New South Wales Greenhouse Gas Abatement Scheme, New Zealand Emission Trading Scheme, and Regional Greenhouse Gas Initiative. The rationale of including forestry offsets in a domestic emission trading scheme was derived from the fact that forestry offset credits can provide cost-effective ways for market participants to commit their emission targets and expand abatement activities through reducing greenhouse gases in other geographical locations as well as other industrial sectors. Even though forestry offset credits have risks induced by their technical complexities in terms of accounting, additionality, and leakage, the integration of forestry offset credits into an emission trading scheme would be able to provide positive opportunities both to forestry sectors and other industrial sectors. In addition, there are technical questions which need to be answered in order to maintain these opportunities.

신재생에너지를 내연기관의 연료로 사용했을 때 나타나는 온실가스 감소량 및 디젤연료를 사용했을 때의 효율 비교, 또한 온실가스를 감소했을 때 생기는 탄소배출권으로 얻을 수 있는 경제성을 연구해보고, 다른 분산전원방식인 태양력, 풍력, 연료전지 등을 사용했을 때의 온실가스 감소량 및 효율성을 비교해 본다. 그리하여 앞으로 다가올 탄소배출권 시장 경쟁에서의 가장 효과적인 방법을 모색해본다.

우리나라는 저탄소 녹색성장을 위한 국가 온실가스 감축목표 즉 2020년까지 BAU 대비 30% 감축을 달성하기 위해 총량제한 배출권거래제를 도입하는 "온실가스 배출권의 할당 및 거래에 관한 법률"이 2012년 5월 14일 제정됨에 따라 2015년 1월 1일부터 온실가스 배출권거래제가 본격 시행된다. 배출권거래제를 통해 기업은 온실가스 감축에 소요되는 비용부담을 줄일 수 있고 그 만큼 산업경쟁력 확보가 가능하게 된다.

We analyze the learning-by-doing effects of the allowance pricing system on the Korea's emission trading scheme. The price of allowance (Korean Allowance Unit) is influenced differently by internal market factors and economic conditions variables in the first (January 2015 to June 2016 ) and the second commitment year(January 2016 to June 2017). The prices and transaction volumes of complementary credits (KCU and KOC) as well as economic conditions variables (such as call rate, exchange rate, stock price) are statistically significant only for the second commitment year. Thus, the learning-by-doing effect makes the market participation decision on K-ETS market more efficient in the second commitment year, adopting the previous experience and knowledge in the K-ETS market. The factors estimated significantly in both commitment periods include the institutional binary variable for requiring the submission of the emissions verification reports issued both on February and March.

This article compares two different auction designs for $CO_2$ emission allowances, namely uniform pricing and multiple pricing, in view of market efficiency. Experimental economic method of Buckley et al. (2004) is applied in this analysis. As a result of this analysis as expected, multiple pricing method brings out Winner's curse. It means that uniform pricing method is more efficient than multiple pricing method.
