Who We Are
Let’s Build the
Future Together
The International Solar Alliance (ISA) is a global intergovernmental organisation dedicated to accelerating the deployment of solar energy as a pathway to energy access, energy security, and sustainable development. Established in 2015 as a joint initiative of India and France on the sidelines of the COP21 Paris Climate Conference, ISA was created to mobilise collective action against climate change through the widespread adoption of solar energy solutions.
Today, ISA has evolved into a global platform for international cooperation on solar energy. Following an amendment to its Framework Agreement in 2020, membership is open to all Member States of the United Nations, enabling countries across the world to collaborate in accelerating solar deployment.

History of ISA
The International Solar Alliance (ISA) is an action-oriented, member-driven, collaborative platform for increased deployment of solar energy technologies as a means for bringing energy access, ensuring energy security, and driving energy transition in its Member Countries.
The International Solar Alliance was conceived as a joint effort by India and France to mobilize efforts against climate change through deployment of solar energy solutions. It was conceptualized on the sidelines of the 21st Conference of Parties (COP21) to the United Nations Framework Convention on Climate Change (UNFCCC) held in Paris in 2015. With the amendment of its Framework Agreement in 2020, all member states of the United Nations are now eligible to join the ISA. At present, 119 countries are signatories to the ISA Framework Agreement, of which 99 countries have submitted the necessary instruments of ratification to become full members of the ISA.
The ISA Framework Agreement was opened for signature during the COP22 at Marrakesh on 15 November 2016.
