To promote the integrated approach it is implementing, France continues to be committed to maintaining the momentum created by COP21. It therefore actively participated in COP23 held in Bonn (Germany) from 6 to 17 November. States met to work on formulating the rules for implementing the Paris Agreement and discuss raising the level of ambition of national climate commitments. Finally, France, together with the United Nations and the World Bank, organised a climate summit on 12 December 2017, two years after the adoption of the Paris Agreement. The One Planet Summit will focus in particular on giving new impetus to countries` climate finance efforts The Paris Agreement has a « bottom-up » structure, unlike most international environmental treaties, which are « top down » and are characterized by internationally defined standards and objectives to be implemented by States.  Unlike its predecessor, the Kyoto Protocol, which sets commitment targets that have the force of res judicata, the Paris Agreement, focused on consensus-building, allows for voluntary and national targets.  Specific climate objectives are therefore more politically encouraged than legally linked. Only the processes governing reporting and verification of these objectives are prescribed by international law. This structure is particularly notable for the United States – in the absence of legal targets for reduction or funding, the agreement is considered an « executive agreement and not a treaty ». Since the 1992 UNFCCC treaty has received Senate approval, this new agreement does not require further laws of Congress for it to enter into force. The Paris Agreement is a pioneering environmental agreement that was adopted by almost all nations in 2015 to combat climate change and its negative effects. The agreement aims to significantly reduce global greenhouse gas emissions in order to limit the increase in global temperature to 2 degrees Celsius above pre-industrial levels during this century, while pursuing ways to limit the increase to 1.5 degrees. . . .
