Finally, countries may not be motivated to change their environmental policy 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. Most environmental problems are cross-border and often global and can only be effectively addressed through international cooperation. That is why the Lisbon Treaty stipulates that one of the main objectives of the EU`s environmental policy is to promote action at the international level to address regional or global environmental problems, and in particular to combat climate change. The EU is actively involved in the development, ratification and implementation of multilateral environmental agreements. Between 1857 and 2012, 747 multilateral agreements on the environment were concluded.  After the Intergovernmental Conference in Stockholm in 1972, the creation of international environmental agreements multiplied.  The United Nations has made MMAs popular, most MMAs have been implemented since 1972 at the United Nations Conference on the Human Environment (also known as the Stockholm Conference).  The Stockholm Declaration was adopted by the 113 countries attending the conference and was the first major universal document in an environmental issue.
 A detailed table of international environmental agreements, to which the EU is already a party or signatory, has been drawn up. 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). In addition to examining the link between specific trade commitments in environmental agreements and WTO rules, the negotiations also examined procedures for MEA secretariats and regular WTO information exchange committees. 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). 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.”  These negotiations aim to reaffirm the importance of cooperation between trade and environmental policies for the benefit of both. They focus on how WTO rules apply to WTO members who are parties to environmental agreements, including clarifying the link between certain trade measures taken under environmental agreements and WTO rules.
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 principles of the WTO are based on non-discrimination, free trade by abolishing obstac
