The Paris Agreement goes into force on the thirtieth day after the date on which at least 55 Parties to the Convention accounting for at least an estimated 55 percent of the total global greenhouse gas emissions have deposited their instruments of ratification, acceptance, approval or accession with the United Nations Depositary. Currently, 61 Parties have ratified, accounting for 47.79 percent of global greenhouse gas emissions.1China and the United States have ratified (although the United States has not gotten approval from the Senate), but Russia, the third largest emitter of greenhouse gases, has not. And India, the fourth largest emitter of greenhouse gases, intends to ratify next month.2 That said, however, there is no enforcement mechanism in the agreement, so there is no way to force non-complying countries to comply.
