The NDC Portal exists to alleviate the challenge of information asymmetry that currently plagues the international community in respect to UNFCCC Parties Nationally Determined Contributions (NDCs).

This app follows an API-first design, and is intended to provide interested parties with the information needed to analyze the similarities and differences between Nationally Determined Contributions. Using data compiled by the German Development Institute / Deutsches Institut für Entwicklungspolitik (DIE), each NDC is evaluated by 138 ranking qualifiers and metrics, which practitioners can utilize to gain insights, assess progress, gauge ambition levels, and craft policy.

For more information, please visit the NDC List for a general overview, view the fully-browsable API, and refer to the Documentation Page for a detailed overview of the API. For information about data usage and license, please visit the Data License page.
