These strategic objectives can only be achieved if a number of important international environmental agreements are actively supported and properly implemented, both at EU and global level. Global environmental issues that MEAs are expected to address include biodiversity loss, the adverse effects of climate change, ozone depletion, hazardous waste, organic pollutants, marine pollution, trade in endangered species, destruction of wetlands, etc. The EU has already ratified many international environmental agreements, whether at the global level (multilateral agreements negotiated under the auspices of the United Nations) and at the regional level (for example. B within the framework of the UNITED Nations Economic Commission for Europe or the Council of Europe) and at the sub-regional level (for example. B for the management of seas or cross-border rivers). 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. Global political systems, differences and conflicts are obstacles to the development of environmental protocols. First, maintaining sovereignty means that no country can be forced to participate, but is simply invited to participate. Therefore, as French says, “international law has the force of moral evocation, but few real teeth.”  Second, the North-South conflict can block cooperation and provoke conflict.
The countries of the world`s South, considered the poor, generally regard the countries of the North, the rich, as the need to take responsibility for environmental degradation and to effect significant changes in their way of life, both of which the North considers reasonable. The South maintains that the North already had the opportunity to develop and to have already been heavily polluted during its industrial development. The World Trade Organization participated in the ACCORD negotiations because of the trade impact of the agreements. The organization follows trade and environmental policies that promote the protection and preservation of the environment. The aim is to reduce trade barriers and coordinate trade actions with environmental policies.  Because MEAS protects and protects the environment, they can help ease trade restrictions.  THE WTO principles are based on non-discrimination, free trade by removing trade barriers and fair competition, and THE MEAs have been rejected because they are not in line with the organization`s principles. The WTO collaborates and implements more than 350 MEAS worldwide. [Citation required] Most of the agreements cover five key countries working to improve the environment and free trade.  WTO members are legally bound to respect the negotiated removal of trade barriers.  However, conflicts have arised as a result of trade restrictions.
 Finally, countries may not be motivated to change their environmental policies because of conflicts with other interests, including economic prosperity. If environmental protocols cause economic hardship or damage to one country, it may escape protocols, while other countries comply with them, resulting in a classic problem of parasitism. In addition, environmental protocols can be criticized for scientific uncertainty or, at the very least, for a lack of synthesis of scientific information that can be used for “conflicting interests and disaster”.  This can now be seen as an excuse defined as skepticism about climate change.
