In 1987, the Brundtland Report gave priority to sustainable development. In particular, it made reference to the "interrelated crises" of the future global challenge, including poverty, unequal development, environmental degradation, resource depletion, economic crises and non-sustainability. Subsequently, the identification and improvement of institutional gaps were prioritized, while emphasis was placed on energy and environmental objectives, and in particular international cooperation, institutional reform and joint management of resources. Finally, and after consideration, regarding Amendment No. 106, the United Nations General Assembly was invited to transform this report into a United Nations Programme for Sustainable Development.
