India’s negotiations over climate issues have been a major key agenda of India’s foreign policy since 2014, under the NDA-led Modi government. India’s engagement has also been reflected through its bilateral and multilateral actions, while attending several global climate summits and formulating the climate agenda with global leaders. The Narendra Modi government has therefore introduced several ranges of climate agendas on these global platforms while conducting India’s climate diplomacy as a key aspect of India’s foreign policy. This not only shows India’s evolving role in global climate dialogue but also an increasingly leading role to strengthen global financial institutions, the industrial potential of states, and technologically advanced world governments to combat climate change. Thus, the foreign policy of India is, in fact, paying serious heed while putting India’s domestic agenda in front of the global climate regime. Although India's role cannot be undervalued as a pioneer country, to raised its voice to settle global climate issues like climate justice, carbon equity, and sustainability on the global platform from time to time. Moreover, the problem of clean energy, International Solar Alliance (ISA), and technology sharing and innovation are a few important areas of India’s emerging climate diplomacy in its foreign policy. However, focusing on energy security, climate finance, circular economy, and green building techniques begins a new phase of India’s modern climate diplomacy. Hence, the study tries to examine the historical growth of India’s climate diplomacy in terms of its foreign policy, along with the changing agenda of India’s climate diplomacy under the Narendra Modi government, and its new priorities that remain inadequate to fulfil the primary objective of India’s foreign policy. At the end, the major issues and challenges of India’s climate diplomacy have been critically examined in the course of India’s foreign policy. Priorities have also been extended to understand Modi’s bold step to make India a responsible state to lead the COP summit and influence the current World Climate deliberations.
