Intended Nationally Determined Contributions (INDCs)

Further to the negotiations under the Ad Hoc Working Group on the Durban Platform for Enhanced Action (ADP), the Conference of the Parties (COP), by its decision 1/CP.19, invited all Parties to initiate or intensify domestic preparations for their INDCs towards achieving the objective of the Convention as set out in its Article 2, without prejudice to the legal nature of the contributions, in the context of adopting a protocol, another legal instrument or an agreed outcome with legal force under the Convention applicable to all Parties.

The Conference of the Parties (COP), by its decisions 1/CP.19 and 1/CP.20, invited all Parties to communicate to the secretariat their INDCs well in advance of COP 21 (by the first quarter of 2015 by those Parties ready to do so) in a manner that facilitates the clarity, transparency and understanding of the INDC. In decision 1/CP.20 the COP also invited all Parties to consider communicating their undertakings in adaptation planning or consider including an adaptation component in their intended nationally determined contributions.

In pdf-icon decision 1/CP.20 it is further specified that in order to facilitate clarity, transparency and understanding, the information to be provided by Parties communicating their intended nationally determined contributions may include, as appropriate, inter alia, quantifiable information on the reference point (including, as appropriate, a base year), time frames and/or periods for implementation, scope and coverage, planning processes, assumptions and methodological approaches including those for estimating and accounting for anthropogenic greenhouse gas emissions and, as appropriate, removals, and how the Party considers that its intended nationally determined contribution is fair and ambitious, in light of its national circumstances, and how it contributes towards achieving the objective of the Convention as set out in its Article 2.

By decision 1/CP.21, paragraph 13, the COP reiterated its invitation to all Parties that have not yet communicated their INDC, to do so as soon as possible and well in advance of COP 22. In paragraph 22, the COP also 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 accordance with paragraph 30, all communicated NDCs have been made available on the public NDC interim registry
