Such an agreement would need to achieve four things : fix a realistic new overall ceiling on opec ' s annual production ( which means 16 million barrels a day or less ) ; be sufficiently flexible to allow output to adjust to the sharp seasonal swings in world oil demand ; see that individual countries ' production quotas are both observed and effectively policed and look like lasting whatever happens to non - opec output 這樣一個協(xié)議應(yīng)當(dāng)解決四個方面的問題:一是,從總體上為歐佩克制定一個新的、切實的年度產(chǎn)量上限(意味著每天1600萬桶或更少) ;二是,在世界石油需求季節(jié)性劇烈波動面前給予充分的靈活性,允許對產(chǎn)量進(jìn)行調(diào)整;三是,確保每個國家均按照配額生產(chǎn)并且得到有效的監(jiān)控;四是,不論非歐佩克成員國的石油輸出如何變化,恒守自己的原則。
