The guidelines for an AED are defined by the participating countries. The United Nations and the World Trade Organization are important intergovernmental organizations for forging and implementing agreements. Australia is known for its wide diversity of animal species and diverse environment, which encompasses beaches, deserts and mountains, and climate change is a major problem. The country is under the largest hole in the world`s ozone layer, which has an impact on the environment. Australia`s proximity to Antarctica raises concerns about sea level rise and changes in ocean currents that affect the climate. The main international instruments that enable countries to cooperate on a wide range of global environmental challenges are international conventions and treaties on the environment and natural resources, also known as multilateral environmental agreements (EAs). How we see the effectiveness of the protocols depends on what we expect from them. With little administrative or real authority, the protocols increase government concern, improve the contractual environment and increase capacity by transferring assets. But as long as sovereignty is intact, environmental protocols will not have an impact on changes in relation to public or public apathy, guarantee national measures or materialize overnight. The progress of international environmental law could be, as wiener suggests, like the turtle, slow but constant.  An international environmental agreement or sometimes an environmental protocol is a kind of treaty of international law that allows them to achieve an environmental objective. In other words, it is an “intergovernmental document that is designed as legally binding and is primarily aimed at preventing or managing the human impact on natural resources.”  The use of multilateral environmental agreements began in 1857, when a German agreement regulated the flow of water between Lake Constance and Austria and Switzerland. International environmental protocols were put in place as part of environmental policy following the widespread perception of cross-border environmental problems in the 1960s.  In all these areas, the Union is a strong supporter of international environmental action and cooperation and an active player committed to promoting the concept of sustainable development around the world.
