The U.S. signed on to the Copenhagen Accord to slow climate change, following through with its pledge to support an agreement widely criticized for being non-binding.
The biggest economy aims to cut greenhouse-gas emissions about 17 percent by 2020, the U.S. said in a letter late yesterday to United Nations Framework Convention on Climate Change Executive-Secretary Yvo de Boer, repeating a vow made in December while brokering the accord in Denmark’s capital.
