What mechanism does the Paris Agreement rely on for countries to set and update their climate actions?

• A. International weather quotas set by a central authority.
• B. Nationally Determined Contributions (NDCs) and climate finance.
• C. Mandatory emission caps set by UN every five years.
• D. Technology transfer agreements only.

Answer: (B)

The Paris Agreement relies on each country deciding its own climate actions through Nationally Determined Contributions. These NDCs describe how a country will reduce emissions and adapt to impacts, and they are meant to be updated at least every five years to raise ambition. A transparency framework and global stocktake track progress, helping countries review and strengthen their plans. Climate finance supports implementation, especially in developing nations. There is no central authority forcing quotas, nor mandatory UN emission caps, and technology transfer alone isn’t the mechanism.
