Entry into force of the Paris Agreement: The legal process
The Paris Agreement on climate change is an international legal instrument by which states have established rights and obligations to address the causes and impacts of climate change. According to Article 21, the agreement will enter into force on the 30th day after the date on which at least 55 parties to the United Nations Framework Convention on Climate Change have deposited their instruments of ratification, acceptance, approval or accession with the Secretary-General of the United Nations, who will act as the depositary of the agreement. These parties must account in total for at least an estimated 55 per cent of total global greenhouse gas emissions. There are a number of key steps that need to be followed to bring the agreement into force.
