India does not endorse efforts to dilute expectations from the Copenhagen climate summit and is pushing for a "legally binding substantive" outcome, a matter that will be discussed during Prime Minister Manmohan Singh talks with US President Barack Obama. Coinciding with the Copenhagen meet, India is considering a legislation incorporating all its action plans and national missions aimed at reducing dependence on coal based fuels and "improving" the environment by 20 per cent by 2020.

During their meeting on Tuesday, Singh and Obama will discuss what kind of outcome is expected from Copenhagen meet beginning on December 7, sources said.

India and a number of developing countries want "legally binding substantive outcome" from the meet and do not endorse the recent statement by the US and other APEC nations that a mere political declaration would do.

The sources said that India does not want the world to give up with regard to Copenhagen meet, as is being done by some countries.

India feels that there is still time for Copenhagen conference, particularly its high-level segment beginning on December 16, and efforts should be made to push the negotiations for an outcome mandated by United Nations Framework Convention on Climate Change and Bali action plan.
