Abstract

Abstract: An empirical research was made on the carbon market risk measurement of the European Union emissions trading scheme. Based on the analyses of carbon price volatility, the conditional variance and extreme value theory were incorporated into the VaR framework to develop an integrated GARCH-EVT-VaR model for the carbon market. It is applied to estimate market risks of the EU ETS, and empirical results indicate that the GARCH-EVT-VaR model makes more accurate risk measurement of the carbon market than the traditional model. The EUA (Europe Union Allowance) and CER (Certificated Emission Reduction) are exposed to the same level of market price, in spite of differences in their policy risk, legal risk and credit risk. Market risks of EUA and CER are significant correlated, which can be used to make risk management strategies for the carbon market.

Key words: carbon market, risk measurement, price volatility, GARCH-EVT-VaR

摘要： 对欧盟碳市场风险进行实证研究, 在分析碳市场价格波动特征基础上, 将条件方差和极值理论纳入 VaR 计量框架, 建立量化碳市场价格波动风险的GARCH-EVT-VaR 模型。应用该模型对欧盟碳排放交易市场(EU ETS)进行实证研究, 结果显示: 碳市场价格波动具有尖峰、厚尾、自相关、波动性聚类和条件方差等典型特征, EUA 和CER 价格波动呈现显著同步性; 碳市场存在显著的极端价格波动风险, GARCH-EVT-VaR 模型能够更准确地量化碳市场风险, 从而为应对极端事件预留充足的风险储备。
