US Withdraws from International Solar Alliance Amid Broader Exit from Global Bodies

The United States has officially left the International Solar Alliance (ISA), a multilateral initiative spearheaded by India to promote widespread adoption of solar energy worldwide. This withdrawal forms part of a larger U.S. decision to disengage from 66 international organizations.

Officials from India’s Ministry of New and Renewable Energy (MNRE) confirmed that the government is aware of the move. “The ISA today represents 125 members or signatory countries. ISA remains focused on its objective of supporting member countries in collectively addressing key common challenges to scaling up of solar energy, in line with their needs, to achieve universal energy access,” an MNRE official stated.

The official emphasized that the alliance will persist in its efforts, adding, “ISA will continue to work with member countries, particularly Least Developed Countries (LDCs) and Small Island Developing States, in development and deployment of solar energy, mobilising finance, building capacity, and reducing risk perceptions.”

Established in 2015 at the COP21 climate summit in Paris and co-founded by India and France, the ISA is headquartered in Gurugram. It now includes 125 member and signatory nations, focusing on overcoming barriers to solar expansion to ensure universal energy access.

The U.S. departure stems from a presidential memorandum instructing agencies to exit various multilateral entities deemed misaligned with American priorities. These span climate, energy, and development sectors, including UN-affiliated and independent groups.

Despite discussions prompted by the decision regarding international climate collaboration, authorities noted no immediate effects on the ISA’s current programs or partnerships with participating nations.

The United States had become the ISA’s 101st member in November 2021, with the accession announced by then-U.S. Special Presidential Envoy for Climate John Kerry during the COP26 summit. At that time, the U.S. expressed commitment to hastening global solar uptake and aiding solar-driven energy shifts, especially in developing regions.

Launched as a platform for solar financing, policy guidance, and technical support—primarily in Africa, Asia, and Latin America—the ISA continues its mission undeterred.
