The Copenhagen Accord on Tuesday became a part of United Nations climate negotiation, but as an option.

The United Nations Framework Convention on Climate Change (UNFCCC) in December 2009 had only taken note of the accord, an agreement between 26 rich and influential countries, and refused to endorse it.
Over 80 nations, including India, had associated with the accord, which US considers its acceptance by the global community and wants it to be “formally” part of future climate talks.
India and China have opposed the move saying negotiations should be conducted only on two existing UN tracks — Kyoto Protocol and Long term Cooperative Action (LCA) — but agreed to incorporate some elements of the Copenhagen accord in the LCA text.
On Tuesday, the UNFCCC secretariat came with a new draft on LCA having elements of the Copenhagen Accord as alternative options for the nations to agree. The text will be discussed at a 12-day conference of climate negotiators of 193 nations starting in Bonn, Germany from May 31.
