Communication of first NDCs

By its decision 1/CP.21, paragraph 22, the Conference of the Parties (COP) invited Parties to communicate their first NDC no later than when the Party submits its respective instrument of ratification, acceptance, approval or accession of the Paris Agreement. In the same paragraph, the COP further stated that if a Party has communicated an INDC prior to joining the Agreement, that Party shall be considered to have satisfied the provision of decision 1/CP.21, paragraph 22, unless that Party decides otherwise.

The following Parties have deposited an instrument of ratification, acceptance, approval or accession, and are therefore considered to have satisfied the provisions of 1/CP.21, paragraph 22. The INDCs of these Parties are available on the INDC platform.

More information about the status of communicated NDCs can be found on the NDC interim registry.
