Understanding the Rio Declaration on Environment and Development

The question asks about the specific year in which the Rio Declaration on Environment and Development was approved by the United Nations. This declaration is a landmark document in the field of international environmental law and sustainable development.

The Rio Declaration was a key outcome of the United Nations Conference on Environment and Development (UNCED), often referred to as the Earth Summit. This major conference brought together leaders from around the world to address pressing environmental and developmental challenges.

Let's examine the options provided and consider the historical context:

• 2018: This year is too recent for the approval of the foundational Rio Declaration.
• 2002: This was the year of the World Summit on Sustainable Development (also known as Rio+10) held in Johannesburg, which reviewed progress since the Earth Summit, but was not when the declaration was initially approved.
• 1992: This is the year the United Nations Conference on Environment and Development (Earth Summit) was held in Rio de Janeiro, Brazil. The Rio Declaration was one of the principal documents adopted at this conference.
• 2012: This was the year of the United Nations Conference on Sustainable Development (also known as Rio+20) held in Rio de Janeiro, which marked the 20th anniversary of the Earth Summit, but was not the year of the declaration's approval.

Based on the historical record, the Rio Declaration on Environment and Development was indeed approved at the Earth Summit in Rio de Janeiro in 1992.
