All top emitters back Copenhagen climate deal: U.N.

OSLO (Reuters) - About 110 nations including all major greenhouse gas emitters led by China and the United States back the non-binding Copenhagen Accord for combating climate change, according to a first formal U.N. list on Wednesday.

The list, helping end weeks of uncertainty about support for the deal, was issued by the U.N. Climate Change Secretariat three months after the pact was agreed at an acrimonious summit in the Danish capital.

The accord, falling short of a binding treaty sought by many nations, sets a goal of limiting global warming to below 2 degrees Celsius (3.6 Fahrenheit) but does not spell out what each nation has to do.
