The Copenhagen Accord , a political agreement  struck by world leaders at the 2009 U.N. Climate Change Conference in Copenhagen, calls on participating countries to pledge specific actions they will undertake to mitigate greenhouse gas emissions. This represents the first time ever that all of the world’s major economies have offered explicit international climate pledges.
In the case of Annex I (developed) countries, the nonbinding Accord calls for quantified economy-wide emission targets for 2020. In the case of non-Annex I (developing) countries, it calls for “nationally appropriate mitigation actions,” but does not specify what form they should take. (Least developed and small island countries “may undertake actions voluntarily and on the basis of support.”)
As of May 24, 2010, 99 parties (counting the 27 member states of the European Union as a single party) had filed submissions with the U.N. climate change secretariat :

In the Copenhagen Accord, countries agree that “deep cuts in global emissions are required… so as to hold the increase in global temperature below 2 degrees Celsius…” To date, nearly 50 parties (counting the European Union as a single party) have submitted specific mitigation pledges under the Accord. Several analyses (summarized here ) have assessed whether these pledges are consistent with the goal of limiting global temperature increase to 2 degrees Celsius.
Our review of these analyses finds that:
