Cuba's initial environmental legal framework was founded on the Constitution of 1976. Article 27 stipulated that all citizens and cognizant government agencies are to take measures to ensure a clean environment.
Cuba's current Constitution was enacted in 1992: Article 27 of the new Constitution states:
“The State protects the environment and the natural resources of the country. It recognizes their close connection with sustainable social and economic development, so as to make human life more rational and ensure the survival, well being and safety of the current and future generations. It is the responsibility of the cognizant State or-gans to apply this policy. It is the duty of all citizens to contribute to the protection of the waters and the air, and to preserve the soil, theflora, the fauna, and all of nature's rich potential.”
The Cuban National Assembly passed the first environmental law enacted by Cuba's socialist government in 1981 - Law 33, known as the "Law on Environmental Protection and the Ra-tional Use of Natural Resources."
