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.  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 assessments, access to information and public participation), work accidents, maritime and river safety, environmental responsibility. 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.
In addition, the main light reference agreements have also been grouped according to general environmental themes according to the structure of the situation plan. The use of multilateral environmental agreements began in 1857, when a German agreement regulates the flow of water between Lake Constance and Austria and Switzerland.  International environmental protocols were introduced into environmental policy following widespread perception of cross-border environmental problems in the 1960s.  The action programme also contains a horizontal priority objective to help the EU more effectively address international environmental and climate challenges. It recalls that the Union intends to achieve good results in terms of accession to multilateral environmental agreements (MEAs) and calls on the EU and its Member States to participate proactively in international negotiations on new and emerging issues.
