Review and implications of the international conference on the developed and sustainable environment of the world

Environmental education has become a priority at the international level, the United Nations invited member countries to increase their commitments to the people and create capable citizens to do it.  Environment is one of the main components of sustainable development and requires education.  Meetings in this field have been held since the 1970s and some of them are of special importance due to their influence on the formulation of laws, design and implementation of education programs.

 International environmental law has tried to provide solutions to problems by establishing binding and non-binding regulations.  Sustainable development reduces the tensions caused by the conflicting visions that emerged in the 1970s regarding the limits of growth, and with the interaction between the three economic, social and environmental dimensions, it has moved towards international law, the Stockholm Declarations of 1972, Rio 1992 and  Johannesburg, 2002, emphasize environmental protection and achieve development as the key to solving problems.  The Rio+20 summit can be a suitable platform for a set of policies that support the transition to a green economy.  This research examines international legal approaches to protect the environment.  In terms of comparing the achievements of the above summits, it can be acknowledged that the Rio 1992 summit has more favorable results than other summits in terms of the efficiency of international legal approaches to protect the environment and accept international obligations.
