Environment Minister Prakash Javadekar said that the convention should not be "rewritten" and appealed to the nations to make the Paris conference an event for celebration of a universal yet differentiated new agreement, where every country takes action which it determines on its own.

"We should not forget that what will lapse is the Kyoto Protocol and not the United Nations Framework Convention on Climate Change (UNFCCC). We should not try to rewrite the convention. Annexes are part of the convention's basic structure stemming from historical responsibility of countries.

"Let Paris be an event for celebration of a universal, yet differentiated new agreement, where every country takes action which it determines on its own. Such collective action will address the challenge of climate change," Javadekar said while making an intervention at the Major Economies Forum on Energy and Climate Change at Luxembourg today.

He was reacting to suggestions from some countries that "Annexes" should not be reflected in the new agreement as Intended Nationally Determined Contributions (INDCs) will themselves result in differentiation through self differentiation.

He cautioned "the developed world that for the success of Paris and for giving a chance to the action under INDCs, no new agenda should be introduced at this late hour."

He said that earlier many countries were not mandated to take any action and the new "climate awareness" made all countries to commit to some action.

"The World moved forward when it decided in Durban that every country will take action on climate front. In Warsaw, it was decided that countries will formulate their INDCs. Each country will chalk out its actions as per its capacity, available resources and support.

"Nationally Determined Contribution concept has a far reaching impact for mitigating the challenge of climate change. This will lead to a better world as it is an evolved mechanism and not a forced one," he said.

Javadekar was referring to the Common But Differentiated Responsibilities (CBDR) principal which is one of the basic foundations of the UNFCCC under which the Paris agreement is being negotiated. The UNFCCC had placed a group of about 40 rich and industrialised countries in Annex-1 which were mandated to take green house cuts.

The countries not named in Annex-1 were called non Annex countries and they did not have any obligations. Ahead of Paris negotiations every country is submitting its climate action plan based on its own capabilities. Developed countries are arguing that this sort of mechanism itself brings in differentiation. Therefore there is no need for going into another sort of differentiation.
