Row over 2020 emissions goal sours Bali climate talks

The European Union took a veiled swipe at the United States at climate talks in Bali on Tuesday over Washington's efforts to remove tough 2020 emissions guidelines for rich nations from draft text.

U.N. climate talks in Bali have become dominated by disputes about whether a final text, or Bali roadmap, should omit any reference to scientific evidence that rich nations should axe greenhouse gas emissions by 25 to 40 percent below 1990 levels by 2020.

Any watering down or outright removal of this non-binding range would anger developing nations, who are demanding rich nations do more to cut their own greenhouse gas emissions.

The row has overshadowed a separate finance ministers meeting in Bali and 10th anniversary celebrations for the Kyoto Protocol.
