The Rio Declaration on Environment and Development, often shortened to Rio Declaration, was a short document produced at the 1992 United Nations Conference on Environment and Development (UNCED), informally known as the Earth Summit.
The Rio Declaration consisted of 27 principles intended to guide countries in future sustainable development.
Subsequently, the international community has met twice to assess the progress made in implementing the principles of the document; first in New York City in 1997 during a General Assembly Session of the UN, and then in Johannesburg in 2002.
[1] Referring to the "integral and interdependent nature of the Earth, "our home", the Rio Declaration proclaims 27 principles.
The Rio Declaration expresses a positive view of traditional ecological knowledge.
