Faculty Online Seminar – “Price Stabilization Mechanisms in Emissions Trading Schemes: Design and Performance of China’s Pilot” by Prof. Wang Banban

Following the experience of high price instability and unpredictability in the European Emissions Trading Scheme (ETS), the management of carbon prices is a key concern for Chinese authorities. The objective is to avoid excessive price volatility in daily trading and stabilize the intrinsic price trend. Building on environmental economics and financial market theories, this study reviews the design of carbon price stabilization mechanisms in China’s seven pilot ETSs and assesses their performance. The pilot ETSs have incorporated most price stabilization mechanisms recommended in the literature, including price ceiling–floor, intensity-based allocation, ex-post adjustment of allowances, intertemporal flexibility, and daily trading risk management. By examining this wide range of mechanisms, the analysis helps understand the different design options available to stabilize carbon prices. Furthermore, by decomposing carbon price data in the different pilot ETSs, the analysis helps evaluate the effectiveness of these mechanisms. However, we are cautious about the desirability of regulatory intervention for influencing carbon market prices.
