With three days left to seal a deal at Copenhagen, climate change champion Al Gore has called on developed and developing countries to reach "compromises" on their key differences for the sake of future generations.
The former US Vice President and Nobel Laureate called for transparency in the contentious issue of financial commitments by developed countries and monitoring of domestic actions that developing nations are resisting.
"If their id transparency to both of these measures then it has a feeling of fairness and equality," he said.
"The world community should know the pledges (financial) are not going to result of the repositions of the old pledges."
At the same time it is difficult for me to understand why the world should not also ask for the ability for itself whether or not the pledges of mitigation from the largest global warming polluters in the work are in fact being honoured for mitigation that is supported and unsupported," he added.
Emerging economies India and China have made it clear that thy will not allow international scrutiny of their national voluntary measures taken that count as "unsupported action" (not backed by funds or technology from outside).
"All evaluation for unsupported action will be done domestically and unaccountability will be with our Parliament and nobody else," India Environment Minister Ramesh said on his third day at the Copenhagen Climate Change Conference where he is currently attending ministerial meetings.
