A draft deal from the ongoing UN climate meeting in the Mexican resort city Friday called on rich countries to cut greenhouse gas emissions by 25 to 40 percent compared with 1990 levels.

"Achieving the lowest levels assessed by the Intergovernment Panel on Climate Change (IPCC) would require the parties as a group to reduce in a range of 25 percent to 40 percent," said the draft being discussed at the 16th Conference of the Parties to the United Nations Framework Convention on Climate Change (UNFCCC).

The document urged the parties to raise their own level of emissions reduction and make contribution to the global target.

The commitment of the UNFCCC parties falls around 40 percent short of what is needed to keep the average global temperature 2 degrees Celsius lower than the pre-industrial level, according to a United Nations Environment Program report released last month.

The previous climate conference had reached consensus on the commitment in Copenhagen, Denmark, last year.

The document also unveiled the emissions reduction targets that developed nations wish to reduce via land use changes

and reforestation activities.

In the document, the European Union pledged to reduce emissions by 283.2 megatons of carbon dioxide equivalent (Mte), followed by Canada with 105.4 Mte. Russia also promised to lower its emissions by 89.1 megatons.
