在西班牙巴塞罗纳举行的国际气候会议进入最后一天，但是各国官员未能就新的气候公约框架达成共识。与会代表已经进行了一周的会议，以制定出一个初步计划，为超过190个国家下月在哥本哈根签署该协议扫清道路。
但是联合国气候变化框架公约行政秘书星期五表示，要正式出台一份具有法律效力的文件恐怕还需要一年的时间。谈判代表们下个月在丹麦首都哥本哈根商讨新公约的框架，正式的公约会在2012年最终敲定。现有的京都议定书 国际气候公约将于2012年期满失效。
Senior officials from countries around the world have entered the last day of a climate conference in Barcelona (Spain) without an agreement on a blueprint for a new climate treaty.Delegates have been meeting in the Spanish coastal city for a week to work out a plan that would clear the way for more than 190 nations to sign an accord next month in Copenhagen.
But a United Nations official (UN executive secretary of the Framework Convention on Climate Ivo de Boer) said Friday it may take another year to put in place a legally binding document. He said negotiators will meet in the Danish capital to try to agree on a framework for the treaty, which would be finalized in 2010.The current climate treaty, the Kyoto Protocol, expires in 2012.
