Based on the analysis of the dynamics of carbon price volatility, this article proposes to develop a combined extreme value theory and conditional variance based Value-at-Risk model (GARCH-EVT-VaR) for short-term risk measurement and estimation of the carbon spot market under the European Union Emission Trading Scheme (EU ETS). The model is implied to the EUA spot market and compared with the traditional GARCH-VaR model, the empirical results show that the GARCH based model underestimates market risks by overlooking the great price shocks, but the GARCH-EVT based model has the ability to take those extreme jumps into its risk estimations.
