The negotiations on the Paris regulatory framework at COP 24 proved in some respects to be more difficult than those that led to the Paris Agreement, as the parties faced a mix of technical and political challenges and, in some respects, increased engagement in trying to develop the general provisions of the agreement through detailed guidelines. Delegates adopted rules and procedures on reduction, transparency, adaptation, financing, periodic inventory and other Paris provisions. However, they were unable to agree on the rules of Article 6, which provides for voluntary cooperation between the parties in the implementation of their NCPDs, including through the use of market-based approaches. From 30 November to 11 On 22 December 2015, France received representatives from 196 countries at the United Nations Climate Change (UN) Conference, one of the most important and ambitious global meetings ever organized. The goal was nothing less than a binding and universal agreement to limit greenhouse gas emissions to a level that would prevent global temperatures from rising more than 2°C (3.6°F) above the temperature level set before the start of the Industrial Revolution. The Paris Agreement provides a sustainable framework that guides global efforts for decades to come. The aim is to create a continuous cycle that feeds pressure on countries to increase their ambitions over time. In order to promote growing ambition, the agreement defines two interconnected processes, each in a five-year cycle. The first is a “comprehensive inventory” to assess collective progress towards the long-term objectives of the agreement. The parties will then submit new NDCs “informed of the results of the global inventory”.
On June 1, 2017, President Trump announced his intention to withdraw the United States from the agreement. In response, other Governments strongly reaffirmed their commitment to the agreement. ==Cities, states and other non-state actors also reaffirmed their support for the agreement and pledged to further intensify their climate efforts. The United States officially began its withdrawal from the agreement on November 4, 2019; the withdrawal became effective on 4 November 2020. President-elect Biden has promised to return to the Paris Agreement after taking office. Although mitigation and adaptation require increased climate finance, adjustment has generally received less support and mobilized less private sector action.  A 2014 OECD report indicated that in 2014, only 16% of global funds were devoted to climate change adaptation.  The Paris Agreement called for a balance between climate finance between adaptation and mitigation and highlighted in particular the need to increase support for adaptation to parties most vulnerable to the effects of climate change, including least developed countries and small island developing states.
