Climate change emerged as a serious diplomatic concern for India in the early 1990s. India has since been a staunch champion of the developing world in multilateral climate negotiations; from playing a key role in establishing the principle of common but differentiated responsibility and respective capabilities, to forging alliances with countries with shared developmental concerns. Faced with the growing impact of climate change and changing geopolitics, India’s foreign policy on climate change has undergone significant shifts during two decades of multilateral climate talks: First, India’s willingness to undertake domestic climate action as a result of its changing economic status and, second, the role of the political leadership—since Prime Minister Narendra Modi came to power in 2014—in shaping the climate discourse both in the country and abroad. India has, in recent years, shed its defensive, naysayer strategy at climate negotiations and led several multilateral initiatives for climate action. As India celebrates 75 years of its Independence, it is forging a new, confident leadership on issues of climate change. While there is continuity in India’s traditional stance on finance and technology transfer during negotiations, Indian foreign policy has begun to display a marked change in the strategic use of climate change to assert greater power at the global stage.
