An agreement between two nations is called a bilateral agreement on the environment. If the agreement is reached between three or more nations, it is called the Multilateral Agreement on the Environment (MEA). Such agreements, first concluded by the United Nations, deal with issues such as atmospheric policy, freshwater policy, waste and hazardous substances policy, the marine environment, the protection of nature, noise pollution and nuclear safety.  How we see the effectiveness of 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.  Australia is known for its wide diversity of animal species and diverse environment, which includes 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 themes covered in these agreements are very broad: biodiversity and nature protection, climate change, protection of the ozone layer, desertification, chemical and waste management, cross-border water and air pollution, environmental policy (including impact studies, access to information and public participation), work accidents, maritime and river safety, environmental responsibility. Because of these barriers, environmental protocols become an obvious goal for several critical points, such as slow production.
B of the desired effects (due to the ratification process of the Convention), the maintenance of the lowest common denominator and the lack of monitoring and implementation. They can also be criticized for taking a progressive approach in which the principles of sustainable development indicate that environmental concerns must be taken into account in a coherent manner. In 2002, the EAC Heads of State and Government Summit decided that regional and multilateral issues should be negotiated in bulk. The draft framework for joint participation and implementation of regional and multilateral environmental agreements (MEAs) has been finalised. The objective of this framework is to guide EAC partner countries in the implementation of various multilateral environmental agreements to which partner states belong. 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).
