The departure of the United States out of the International Solar Alliance (ISA) is a major blow to the climate diplomacy in India that challenges the strength of the leadership on the issue of renewable energy cooperation in the world arena.
US Pullout of ISA: A Multilateral Climate Action Blow.
In January 2026, the US president Donald Trump issued an executive order withdrawing the country out of 66 global organisations, including the India-led International Solar Alliance ISA Firstly, the ISA, which was co-created by India and France in 2015, was seen as an alliance of countries with high solar potential influencing the timeline of implementing solar power, lowering the expenses of this technology, and facilitating funding of clean energy initiatives. In November 2021, at COP26, the US became the 101st member of the alliance.
The choice made by Trump is indicative of his greater America first agenda, doubting multilateral institutions and placing national sovereignty above international co-operation. The action highlights a backlash of climate multilateralism by Washington, and it will be worrying how the future of collective action against climate change will be.
Why It Matters for India
It is presently under the presidency of India and co-presidency of France in the ISA. Now 125 member countries are represented by the alliance, among these the Least Developed Countries (LDCs) and Small Island Developing States (SIDS) which ISA support in terms of capacity building, reduction of risks, and fund solar projects.
The US withdrawal is significant to India in a number of aspects:
Diplomatic credibility: India has established itself as the world leader in renewable energy. The US withdrawal undermines the international influence of the ISA.
Financing issues: US was supposed to play the role of mobilising fund and technology transfer. Its exit can decelerate the projects in the weak countries.
Geopolitics: The action underscores increased inconsistency between the climate leadership of India and US policy, which may make collaboration between the two countries on clean energy difficult.
Resilience test: India should now mobilize other members particularly the EU and emerging economies to carry on with ISA without the support of the US.
India’s Response
Though it was a setback, the Indian government has reiterated that the ISA is still resolved in its mission. According to officials, the alliance will remain committed to help the member countries to scale up solar energy, and to have universal access to energy.to India, this is the question of keeping the momentum, finding alternative funding and strengthening the alliance with other countries who still believe in climate action. This exit of the US can be a setback to the progress, but on the other hand, India can showcase its leadership by maintaining the alliance on the trump .
