In a significant policy shift, President Donald Trump has ordered the United States' withdrawal from 66 international organizations, including the India-led International Solar Alliance (ISA) and the foundational UN Framework Convention on Climate Change (UNFCCC). This decision, announced through a presidential memorandum on January 7, 2026, comes as part of a broader rollback of US participation in global institutions during what is framed as his second presidential term. The move specifically targets climate and environmental bodies, aligning with Trump's 'America First' agenda, which prioritizes domestic interests over multilateral agreements and questions the fairness of global institutions. The ISA, co-founded by India and France in 2015 and headquartered in Gurugram, Haryana, aims to mobilize $1 trillion in solar energy investments by 2030 to combat climate change. This withdrawal represents a reversal of previous US policy. Under the Biden administration, the US had officially rejoined the Paris Agreement on February 19, 2021, after Trump's initial withdrawal in November 2020. Furthermore, the US became the 101st member of the International Solar Alliance in November 2021, under the Biden presidency, signaling a commitment to global solar energy deployment. The current withdrawal from the ISA and UNFCCC effectively signals a re-withdrawal from the Paris Agreement as well, given that the UNFCCC is its implementing body. Credible sources like the Los Angeles Times, DD News, The Economic Times, The Tribune, India Today, and The New Indian Express have all corroborated this story, reporting the withdrawals on January 7-9, 2026. While the US exit may pose challenges, particularly for collaborative efforts in clean energy, India and other ISA members are expected to continue strengthening the alliance's work, which currently boasts 125 member and signatory countries.
