On June 18, 2018, the National Assembly of Benin adopted Law No. 2018-18 to regulate climate change in the Republic of Benin. This law was promulgated and passed into law as Law No. 2018-18 on August 6, 2018. Its adoption by the National Assembly placed Benin among the first countries to adopt national legislation on climate change. Benin is now able to prevent, protect, and manage the consequences of climate change, as well as support the development of short- and long-term climate programs. Many ask if this law is necessary or is it, in fact, a tactic to conform to international debates on climate change concerns. The current chapter analyzes the law's relevance, originality, innovation, and perspectives. In the time where people all over the world increasingly call for defining action to tackle climate adversity, and save the world from climate disaster and threat, the world leaders in the countries are recommended to replicate the climate law initiative as a proof of political will to implement the Paris Agreement.
