The United States has withdrawn from the International Solar Alliance (ISA) as part of its exit from more than 60 international organisations, following a memorandum signed by the US President Donald Trump.

The memorandum, ‘Withdrawing the United States from International Organisations, Conventions, and Treaties that are Contrary to the Interests of the United States’, directs the US government departments and agencies to initiate withdrawal from 66 United Nations and non-UN bodies.

“…After deliberating with my Cabinet, [I] have determined that it is contrary to the interests of the United States to remain a member of, participate in, or otherwise provide support to the organisations listed in section 2 of this memorandum,” Trump said, informing that the ISA is listed under the same section.

The ISA, a multilateral initiative launched by India and France to promote solar energy deployment, is among the 35 non-UN organisations listed in the order. The list also includes several UN entities such as the Intergovernmental Panel on Climate Change and the UN Department of Economic and Social Affairs.

According to the memorandum, withdrawal entails ceasing US participation in or funding of the listed organisations, to the extent permitted by law.

The ISA, headquartered in India, works with member countries to mobilise investments, support technology collaboration and facilitate large-scale solar energy deployment, particularly across tropical regions.
