Singh will join United States President Barack Obama and over 100 world leaders at the summit with the likelihood increasing of a consensus on a new global deal to replace the Kyoto Protocol which expires 2012.
"We want to be seen as a deal-maker and not a deal-breaker. We have already set our four non-negotiable positions, including no legally binding emission cuts and no peaking year for the emissions as demanded by certain quarters," Union Environment Minister Jairam Ramesh said.
He categorically stated that India's negotiation position remains intact and there were no rifts between the government and the negotiators, Chandrasekhar Dasgupta and Pradipto Gosh, who had initially decided to opt out of the team going to Copenhagen.
Ramesh said he had 'necessary and productive' discussions with them and they will be the part of the delegation to attend the 12-day summit at Denmark.
But it would be tough negotiations with the rich nations, who are planning to table Danish draft which seeks peaking years for all the emerging economies and thus blurring the difference between the industrialised and countries like India and China.
The move is expected to be strongly opposed by India which has, in association with other key emerging countries like Brazil, South Africa, China (BASIC), drafted a proposal to be part of the negotiations, demanding adherence to the Principles of equity as per Kyoto Protocol.
Ramesh while asserting that the Danish draft was totally unacceptable and would lead to stalemate, has nevertheless said that they were going to Copenhagen in a positive frame of mind, prepared to be flexible.
"We want a comprehensive and equitable agreement. We are realistic enough to know such an agreement may not materialise, but we have worked with like-minded countries, with China, and with others, to ensure there is a comprehensive and equitable arrangement," Ramesh said.
Ahead of the crucial negotiations, Chinese foreign ministry spokesperson Qin Gang, in a statement, made clear that any attempt to go against the principles of 'common but differentiated responsibilities' as enshrined in Kyoto Protocol will be no cause for optimism for the deal.
The bloc of the developing countries are seeking for binding emissions cut commitments from industralised nations, technology transfer and capacity-building assistance to developing nations and no legal binding emissions cuts.
Gang added, "We demand that the developed countries fulfill their promises with actions. The Copenhagen conference lies in whether we can adhere to the UNFCCC and its Kyoto Protocol seeking "Common but differentiated responsibilities."
China, which is the second largest polluter has also announced plans for a 20 to 25 percent carbon emission cut by 2020.
Brazil proposes for voluntary reductions of 38-42 per cent by 2020, asking the developed nations to contribute funds and share green technology if they want developing and poor nations to take adequate steps to protect the climate.
Ramesh said the carbon intensity reduction target was voluntary and not binding.
"We have to be the part of the solution and not a deal-breaker. Of course we would ensure that our national interest are kept intact, which revolves round the principles of not taking legal emission cuts," the environment minister added.
