This strategy features in the framework of Agenda 21 as formulated at UNCED (Rio de Janeiro, 1992), now coordinated by the United Nations Commission on Sustainable Development and implemented through national and local authorities.
Agenda 21 recommends that countries should strengthen existing advisory bodies or establish new ones for public environment and development information, and should coordinate activities with, among others, the UN, non-governmental organizations and important media. They should encourage public participation in discussions of environmental policy and assessment. Governments should also facilitate and support national to local networking of information through existing networks.
