Denmark is to host the Climate Change Conference in December The UN Secretary General stressed that the long term price of inaction on cutting carbon emissions far outweighs the short term cost of action. Ruling out failure as an option at the Copenhagen meeting Mr Ban Ki Moon said there is no plan B and the world must sign the deal at Copenhagen.The choice is between sustainable growth and economic turmoil, a choice between inclusive global markets and trade anarchy, a choice between a healthy planet and environmental catastrophe.Summing up the deliberations among world leaders, Mr. Ban noted that there was convergence on five key issues, including enhanced measures to help the most vulnerable and poorest adapt to the impact of climate change as well as setting emission reduction targets for industrialized countries. Heads of State and government also agreed on the importance of developing countries taking mitigation actions with necessary support; scaling up financial and technical resources; and setting up an equitable governance structure.The High level Meeting on Climate Change held on the sidelines of the UN General Assembly provided an opportunity for developing countries to articulate their position on the climate change issue. Developing countries like India which are vulnerable to and are already suffering from the impact of climate change have an important stake in establishing a truly global, transparent and rule based and equitable climate change regime based on the principles of UNFCCC which takes into account the imperatives of poverty reduction and economic development of the developing countries and the historical responsibility of developed countries.

He said the Indian Environment Minister Jairam Ramesh has announced that while India's per capita emission is much lowerthan developed countries they will even look at a per capita emission plus. India was represented by Foreign Minister S M Krishna and Environment Minister Jairam Ramesh at the Summit.The Indian negotiators stressed that India's per capita emissions are only around 1 tonne of Carbon di oxide equivalent per annum, which is a quarter of the global average and half that of the developing countries as a whole.
