Efficient Allocation of CO2 Emissions in Selected OPEC Member Based on Zero Sum Gains (ZSG-DEA) Data Envelopment Analysis Model

As the result of increasing importance of global CO2 emissions and balance between economic development and these gases emission, cooperation between all countries is necessary. The equity in allocation of emission allowances have a significant impact on efficiency of this system. Based on Zero sum gains data envelopment analysis (ZSG-DEA) allocation model and given the premise of fixed CO2 emissions, this paper attempts to determine optimal emissions allocation and creating conditions for cooperation among selected OPEC members. The results show that after initial emission rights were allocated in accordance with the ZSG-DEA model, optimal distribution in these selected countries differs from their current state. Also, Consider to the energy consumption indices, capital formation, population, gross domestic production and CO2 emissions, the optimal emissions in our country is higher than the current level. While Saudi Arabia, Iraq, Kuwait, Qatar and the UAE should reduce their CO2 emissions.
