Abstract
One of the main characteristics of international organizations is that very few of them have the power toapprove binding legal texts. After years of experience in implementing agreements and the gradual occurrence of changes and developments, it is necessary to examine their impact on the protection of the environment and the sustainable exploitation of natural resources. In this regard, ways to modify the contentof legal instruments in order to achieve their goals should also be examined and, if necessary, be addressedby providing an amendment or addition of a supplementary legal instrument to make them more effective.The study examines the role of the United Nations in the development of international environmental law,including UN actions for the environment, in the form of statements and declarations and resolutions of the United Nations.
