At the World Future Energy Summit (WFES) held in Abu Dhabi in January 2018, the Indian government announced the creation of a $350 million solar development fund to enable the financing of solar projects. Isa aligns with its “Towards 1000″ strategy, which aims to mobilize $1 trillion in investment in solar energy solutions by 2030, while providing 1,000 million people with access to energy with clean energy solutions and leading to the installation of 1,000 GW of solar energy capacity. This would help reduce global solar emissions by 1,000 million tonnes of CO2 per year. To achieve these objectives, the ISA adopts a programmatic approach. Currently, the ISA has 9 comprehensive programs, each focusing on a specific application that could help advance the use of solar energy solutions. Activities under the programs focus on 4 priority areas – analysis and advocacy, capacity building, programmatic support, and preparedness and enabling activities, which help create an enabling environment for solar energy investments to gain a foothold in the country. The International Solar Alliance (ISA) is an action-oriented collaborative platform focused on members and the increased use of solar energy technologies as a means to access energy, ensure energy security and promote the energy transition in its member countries. Riccardo Puliti, Senior Director and Head of the World Bank`s Global Energy and Extractive Industries Practice, said: “The World Bank is seeing an increase in our customers` interest in solar energy due to the dramatic cost reductions of recent years. We hope that the World Solar Atlas will help make the crucial planning and investment decisions that need to be made over the next decade to move to more sustainable forms of energy. Piyush Goyal, India`s Minister of Energy, said: “This new tool will help governments and investors get a first indication of the potential of solar resources before making their own more detailed analysis. The Alliance is a treaty-based intergovernmental organization.  The International Solar Alliance Framework Agreement was opened for signature in November 2016 in Marrakech, Morocco, on the margins of the Marrakesh Climate Change Conference (the twenty-second session of the Conference of the Parties or COP 22).
The first day (15. Sixteen countries have signed the agreement: India, Brazil, the Democratic Republic of Congo, the Dominican Republic, the Republic of Guinea, Mali; Nauru; Niger; Tanzania; Tuvalu; Cambodia; Ethiopia; Burkina Faso; Bangladesh and Madagascar.  On 17 November, Guinea-Bissau, Fiji and France also signed the agreement.  On November 6, 2017, Indian Foreign Minister Sushma Swaraj met with Guinean Foreign Minister Mamady Touré. During this meeting, Mamady Touré presented Guinea`s certificate of membership in the International Solar Alliance (ISA) initiated by India. Vanuatu and Liberia have also signed the agreement.  The launch of the International Solar Alliance (ISA) was announced by H.E.M. Narendra Modi, the Honourable Prime Minister of India, and H.E.M. François Hollande, former Honourable President of the France, on 30 November 2015 during the 21st Edition of France. Meeting of the Conference of the Parties to the United Nations on Climate Change (COP-21) in Paris, France.
Former UN Secretary-General Ban Ki-moon attended the launch, alongside heads of state and government from about 120 countries, who reaffirmed their participation in the alliance to focus on promoting solar energy. The following countries are the potential members of this alliance that have signed the framework. Countries marked with a plus have also ratified the framework.  Afghanistan, Bahrain, Belarus, Belgium, Belize, Bhutan, Botswana, Brunei Darussalam, Bulgaria, Cameroon, Congo, Denmark, El Salvador, Grenada, Guatemala, Haiti, Ireland, Jamaica, Liberia, Luxembourg, Maldives, Myanmar, Oman, Paraguay, Philippines, Romania, Saint Lucia, Saint Vincent and the Grenadines, Samoa, Thailand and Trinidad and Tobago is the newest member of this alliance. The alliance is also called the International Agency for Solar Energy Policy and Application (IASPA).  For India, the possible additional benefits of the Alliance could include strengthening relations with major African countries and increasing goodwill for India.   Subsequently, 107 other countries joined the agreement, including all major countries between the tropics of Cancer and Capricorn, including Mexico, Peru, Chile, Paraguay, Brazil, India, Argentina, Australia, New Zealand and China. On November 30, 2015, a conclave began for the sun group, InSPA (International Agency for Solar Policy & Application).  The ISA was conceived as a joint effort by India and France to mobilize efforts against climate change through the use of solar energy solutions.
It was built on the edge of the 21. Conference of the Parties (COP21) to the United Nations Framework Convention on Climate Change (UNFCCC), held in Paris in 2015. With the amendment of the Framework Agreement in 2020, all UN Member States now have the right to join the ISA. At present, 101 countries are signatories to the ISA Framework Agreement, of which 80 countries have submitted the instruments of ratification necessary to become full members of the ISA. Allianz has partnered with the World Bank to present the World Solar Atlas at an ISA event at the World Future Energy Summit in Abu Dhabi. Global Solar Atlas is a free online tool that displays the average annual solar energy potential anywhere in the world, identifying potential locations for solar power generation. The World Bank announced: “This tool will help governments save millions of dollars on their own research and provide solar investors and developers with an easily accessible and unified platform to compare resource potential across sites in a region or countries.”  India, with the support of the France, invited nations to facilitate infrastructure for the implementation of solar projects. The alliance has committed a trillion dollars as an investment and is committed to making the cost of solar energy more affordable for remote and inaccessible communities. The alliance will help India achieve its goal of generating 100 GW of solar power and 175 GW of renewable energy by 2022. Countries support each other in research and development and other high-level activities.  The initiative was launched by Prime Minister Narendra Modi at the India-Africa Summit and a meeting of member countries ahead of the 2015 UN Climate Change Conference in Paris in November 2015.
  The International Solar Alliance Framework Agreement was opened for signature in November 2016 in Marrakech, Morocco, and 200 countries have acceded to it. Apart from these, there are 56 other members, which corresponds to a total of 122 members of the alliance. Recently, Eritrea, Luxembourg, St. Kitts join the International Solar Alliance, the number of members rises to 84 It is also considered by developing countries as an alliance to form a united front and conduct research and development activities for the production of solar energy systems in developing countries.  The ISA strives to develop and deploy cost-effective and transformative solar energy solutions to help member countries develop low-carbon growth pathways, with a focus on achieving impacts in least developed country (LDC) and small island developing states (SIDS). .
