The highest decision-making organ of OPEC is the Conference. The Conference is made up of oil ministers from the member countries and meets twice a year to determine production quotas and other important policies related to the oil market. Its decisions have a significant impact on the global oil industry, as OPEC is responsible for producing a large percentage of the world's oil supply. The Special Fund is a financing mechanism for development projects in member countries, while the Board of Governors oversees the management of OPEC's financial and administrative affairs. The Secretariat is responsible for implementing the decisions of the Conference and for providing technical and administrative support to the organization.
