International Solar Alliance (ISA) is an intergovernmental organisation aimed at promoting solar energy deployment and supporting a global transition to clean and renewable energy.
What is ISA?
- Launched in 2015 at the UN Climate Change Conference (COP21), Paris.
- Jointly initiated by India and France.
- Operates as an action-oriented, member-driven platform to scale up solar energy worldwide.
- Guided by the “Towards 1000” strategy.
Vision and Mission
- Vision: Let us together make the sun brighter.
- Mission: Every home, no matter how far away, will have a light at home.
- Headquarters: Located at the (NISE), Gurugram, India.
Membership
- Initially limited to sun-rich countries lying between the Tropic of Cancer and Tropic of Capricorn.
- After the 2020 amendment, all UN member states are eligible.
- Over 110 countries are signatories; around 90 are full members.
Core Objectives
- Facilitate 1000 GW of global solar capacity by 2030.
- Mobilise USD 1 trillion in solar investments by 2030.
- Provide clean energy access to 1 billion people.
- Reduce 1 billion tonnes of CO₂ emissions annually.
- Promote affordable, reliable, and sustainable solar solutions.
Priority Areas of Action
- Analytics and Advocacy
- Capacity Building
- Programmatic Support
- Readiness and Enabling Activities
