Natural gas constitutes about 24 percent of the world’s total energy consumption and it is considered the second most significant primary energy source, after oil. Among the main objectives of the summit are to coordinate the efforts of producers, to promote the gas industry worldwide, to open up opportunities for exchange of experiences and co-operation in developing advanced technologies, to further expand the utilization of natural gas worldwide and to ensure supplies diversification and reliability through close cooperation among producers. The Gas Exporting Countries Forum (GECF) was established in Tehran, Iran, in 2001. The GECF is an intergovernmental organization of some of the world\'s leading natural gas producers. GECF members together control over 64 percent of the world\'s natural gas reserves, 38 percent of the pipeline trade and 85 percent of the liquefied natural gas (LNG) production. The three largest reserve-holders in the GECF -- Russia, Iran and Qatar -- alone hold about 57 percent of global gas reserves. The GECF members are Algeria, Bolivia, Egypt, Equatorial Guinea, Iran, Libya, Nigeria, Qatar, Russia, Trinidad and Tobago, and Venezuela. Kazakhstan, Norway and the Netherlands are observers.
