Protecting biodiversity

International policy

The Earth Summit held in Rio de Janeiro in 1992 is one of the most significant global environment conferences.

Crucially, it was attended by 172 governments, who recognised that the conservation of biological diversity is "a common concern of humankind."

By the end, 10,000 on-site journalists relayed the following agreements to a waiting world:

• The Rio Declaration on Environment and Development
• The Convention on Biological Diversity
• The Convention on Climate Change
• Agenda 21

The summit message - that a major shift in attitudes was needed to bring about change – had been heard loud and clear.
