Agenda 21 was adopted in Rio de Janeiro on 14 June 1992 by a global partnership of participating nations. Like the Basel Convention, POPs are not directly addressed under Agenda 21. However, it is important to consider the implications of the Agenda with respect to a wide range of global environmental issues, including the sound management of toxic chemicals and hazardous wastes. Chapters 19 and 20 of Agenda 21 address these two issues respectively. The underlying principle of Agenda 21 is to recognise and take actions on the need for a sustainable and integrated global approach to environmental and developmental issues. Agenda 21 continues to be one of the most significant drivers for sustainable development strategies at the national level.
