Union Environment Minister Jairam Ramesh said, "The Danish draft was totally unacceptable."
"We are never going to take on a peaking year for absolute emissions. This is not on the horizon," Ramesh was quoted by media as saying.
The draft document was circulated to a few countries ahead of the Dec 7-18 summit in Copenhagen, which is supposed to draw up an agreement for controlling emissions of carbon dioxide and other gases causing global warming.
According to media report, the Danish document suggests 2025 as the year India reaches its maximum level of emissions before they begin to decline.
