A real options study on cook stove CDM project under emission allowance price uncertainty

Abstract

South Korea is one of the countries that have been actively involved in reducing greenhouse gas emissions and global climate action as a party to the Paris Agreement. As the national emissions reduction target has been getting reinforced, an increasing number of South Korean firms have been participating into the Clean Development Mechanism (CDM) projects to secure CER credits, one of which is the ‘improved energy-efficient cook-stove distribution project’ in developing countries. The purpose of this paper is to develop a real options model to analyze investment decisions on cook-stove distribution CDM project in Myanmar, where we estimate the optimal threshold CER price that makes the investment economically feasible. We also analyze the sensitivity of the threshold price across the investment parameters. The results show that our project was economically feasible at the time the project was launched, as the KOC prices were generally higher than the investment threshold price. The sharp decline of the KOC prices in 2020, however, deteriorated the economic feasibility of the project. The results suggest that various risk factors should be incorporated before making investment decisions.
