While creating a new energy organization, it was decided to utilize the framework of the OECD, as it had experience in dealing with oil and other energy questions, had expertise in economic analysis and statistics, had established staff, physical facilities, legal status and privileges and immunities, and was the principal organization of the industrial countries. However, the OECD has a rule of unanimity, and not all member states were ready to participate. Therefore, instead of an integrated approach, an autonomous approach was chosen.
