A global deal to curb carbon emissions must recognise each country's right to develop, France's foreign minister said in New Delhi on Thursday, as the host of this year's U.N. climate change talks seeks to win India's backing for a global deal, Reuters reported. Laurent Fabius said that efforts to reach an agreement, which is due at the United Nations summit in Paris in December, would fail if any country believed it would hurt their economic prospects. India, the world's third-largest emitter of greenhouse gases, often acts as the voice of the developing world in climate change talks, and winning its support is seen as crucial if countries are to reach a deal. "An agreement that would leave some countries to consider their growth hampered by its provisions will not be accepted," Fabius told an audience at an annual sustainable development summit. Fabius, who was due to meet Indian Prime Minister Narendra Modi later on Thursday, said he understood "the constraints of India" as it seeks to grow its economy.
