Setting a Common Time Frame for Nationally Determined Contributions

The paper examines the operationalization of the Paris Agreement by exploring options for aligning the duration of Nationally Determined Contributions (NDCs) into a common time frame. It argues that a five-year time frame, with the option to indicate a ten-year time frame, would best enhance climate ambition and predictability.

• The Paris Agreement's ambition mechanism relies on individual efforts being communicated every five years and based on assessments of collective progress.
• The author argues that the most effective approach to support the Paris Agreement's ambition cycle and implementation is a five-year time frame that allows for the additional indication of a 10-year time frame.
