The Nationally Determined Contribution (NDC) mechanism was established at the Paris Climate Change Conference in 2015, requiring Parties to take a bottom-up approach to set climate change targets with reference to national circumstances. This paper summarizes the 164 submitted Intended Nationally Determined Contributions (INDCs) as the former version of NDCs, generalizes a common framework of the documents, and delivers the statistical analysis focusing on the four characteristics of national mitigation and adaptation goals, conditions and fairness. Results show significant differences in the text of INDCs of each Party. Although a common text framework is developed, different choices are made in specific demonstration of target, coverage of economic sectors and gases, implementation conditions and fairness. In addition, the climate change negotiation position has a significant impact on the choices of content and form of commitment made by Parties.
