If the United States joined the agreement, it would be technically necessary to implement an NDC within 30 days. On 12 December 2015, after 21 years of negotiations, the United Nations presented a universal and legally binding agreement on climate change. In 2013, at COP 19 in Warsaw, the parties were invited to make their “nationally planned contributions” (INDC) to the Paris Agreement in due course prior to COP 21. These bids represent the mitigation targets set by each country for the period from 2020. The final CNN was submitted by each party after their formal ratification or adoption of the agreement and recorded in a UNFCCC registry. To date, 186 parties have submitted their first NCCs. The Paris Agreement (the Paris Agreement)  is an agreement within the framework of the United Nations Framework Convention on Climate Change (UNFCCC) that deals with the reduction, adaptation and financing of greenhouse gas emissions and was signed in 2016. The language of the agreement was negotiated by representatives of 196 States Parties at the 21st UNFCCC Conference of parties held at Le Bourget, near Paris, France, and agreed on 12 December 2015.   Since February 2020, all 196 UNFCCC members have signed the agreement and 189 have left.  Of the seven countries that are not parties to the law, Iran and Turkey are the only major emitters. France, in conjunction with the UN and the World Bank, hosted a climate summit on 12 December 2017, two years after the adoption of the Paris Agreement.
In particular, the One Planet Summit will focus on boosting countries` climate finance efforts. In addition to formal intergovernmental negotiations, countries, cities and regions, businesses and civil society members around the world are taking steps to accelerate climate cooperation efforts to support the Paris Agreement as part of the Global Climate Agenda. To contribute to the goals of the agreement, countries presented comprehensive national climate change plans (national fixed contributions, NDC). These are not yet sufficient to meet the agreed temperature targets, but the agreement points to the way forward for further measures. INDE has addressed the challenges of eradicating poverty while reducing greenhouse gas emissions. About 24% of the world`s population without access to electricity (304 million) lived in India. Nevertheless, the country planned to “reduce the intensity of its GDP emissions by 33-35% by 2030” from 2005 levels. The country has also attempted to buy about 40% of its electricity from renewable energy sources, not fossil fuels by 2030. INDC found that implementation plans would not be affordable from national resources: it estimated that it would take at least $2.5 trillion to implement climate change measures by 2030. India would achieve this through the transfer of technology (transfer of capacity and equipment from the most developed countries to less developed countries [LDCs]) and international funding, including support from the Green Climate Fund (an end-to-end investment support program in low-emission technologies and the development of populations vulnerable to the effects of climate change). Although the Paris Agreement has entered into force, its implementation has yet to be clarified by numerous enforcement decisions. These are marked by the publication by each party of their long-term climate strategy.
The implementation of the climate plan in July 2017 by Nicolas Hulot, then Minister of Ecological and Inclusive Transition, ensured the implementation of the Paris Agreement at the national level. The adoption of the Paris Agreement is part of a long-standing effort by the scientific community to combat climate change. Negotiations on the Paris regulatory framework at COP 24 proved to some extent to be more difficult than those that led to the Paris Agreement, as the parties faced a combination of technical and political challenges and, in some respects, applied more to the development of the general provisions of the
