聯合國氣候變化會議重點討論京都議定書及新的全球氣候協議

Representatives from nearly 200 nations have begun two weeks of talks aimed at agreements on how to limit greenhouse gas emissions.

Delegates at the U.N. climate change conference in Doha, Qatar will chiefly tackle extending the Kyoto Protocol. The pact, which expires this year, binds developed countries to cut emissions by 5 percent below 1990 levels.

Major greenhouse gas emitters like the United States and China are not part of the deal, while Russia, Japan and Canada say they do not want to be part of an extension to the Kyoto agreement. That would leave only about 15 percent of the world's greenhouse gas emissions covered under a continuation of the pact.

The conference will also include talks on crafting a new global climate deal that would be finalized by 2015 and go into effect in 2020.來自將近200個國家的代表開始舉行爲期兩天的會議，旨在就如何限制溫室效應氣體排放量達成協議。

各國代表在卡塔爾城市多哈舉行聯合國氣候變化會議，重點在於解決京都議定書延長期效問題。京都議定書將在今年期滿失效，該議定書規定發達國家要將溫室效應氣體排放量從上世紀90年代水平削減5%。

美國和中國等溫室效應氣體排放大國沒有簽署京都議定書，而俄羅斯、日本和加拿大表示，不打算簽署延長期效的京都議定書。這將使延長期效的京都議定書只涵蓋全球溫室效應氣體排放量的大約15%。

本次會議還將討論制定一項新的全球氣候協議，該協議將在2015年最後敲定，於2020年生效。
