Prepared by the International Institute for Sustainable Development (IISD), the Sustainable Development Timeline traces milestones in the shifting relationship between the environment and development from 1967 to 1997. The Timeline is divided into five year blocks, each of which features milestones in four spheres of interest: Public Awareness; Institution Building; Reports and Publications; and International Meetings and Agreements. Links to related sites and charts of five key statistics are also provided. An HTML Timeline is available, although it is less comprehensive and ends in 1992.
