Domestic Processes for Joining the Paris Agreementby and -
The Paris Agreement will enter into force when at least 55 Parties to the United Nations Framework Convention on Climate Change (UNFCCC) accounting for at least 55 percent of global greenhouse gas emissions deposit their instruments of ratification, acceptance, or approval with the UN Secretary-General and formally join the Paris Agreement.
WRI assessed the national constitutions of the top 100 greenhouse gas emitters to understand the process by which each country is authorized to deposit its instrument of ratification, acceptance, or approval and join the Paris Agreement as a Party. The extent and breadth of domestic political support that each country will need in order to join the Paris Agreement will depend, at least in part, on its type of process for joining the Agreement. This analysis forms the basis of the Domestic Approval Map within WRI’s Paris Agreement Tracker.
