An international environmental agreement or, sometimes, an environmental protocol is a kind of legally binding treaty that allows them to achieve an environmental goal. In other words, it is “an intergovernmental document intended to be legally binding with a stated primary objective of preventing or managing human effects on natural resources”.  These policy objectives can only be achieved if a number of important international environmental agreements are actively supported and properly implemented, both at Union level and globally. The use of multilateral environmental agreements began in 1857, when a German agreement regulated the flow of water from Lake Constance to Austria and Switzerland.  International environmental protocols became a supporting function in environmental policy, after cross-border environmental problems were widely taken into account in the 1960s.  Canada`s multilateral environmental agreement includes air, biodiversity and ecosystems, chemicals and waste, climate change, environmental cooperation, sea and oceans, and meteorology.  Canada took an initiative because of the diversity of the country`s natural resources, climatic zones and populated areas, all of which can contribute to pollution. A detailed table has been drawn up listing the international environmental agreements to which the Union is already a party or signatory. In addition, the main agreements to facilitate the overview have also been grouped according to general environmental issues, in accordance with the structure of the site plan.
How we see the effectiveness of protocols depends on what we expect from them. With little or no administrative power, protocols increase government concerns, improve the contracting environment, and increase capacity by transferring assets. But as long as sovereignty is intact, environmental protocols will not influence any change in the face of state or public state apathy, guarantee national measures, or materialize overnight. Progress in international environmental legislation, as Wiener suggests, could be slow but steady, as the turtle suggests.  A total of 747 multilateral environmental agreements were concluded between 1857 and 2012.  After the Stockholm Intergovernmental Conference of 1972, the creation of international agreements on the environment stagnated.  MEAS were popularized by the United Nations and the majority of MEAs 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 participating in the conference and was the first major universal document on an environmental issue.  Finally, countries may lack the motivation to change their environmental policies due to conflicts with other interests, including economic prosperity. If environmental protocols cause economic hardship or damage to a country, it may escape the protocols, while other countries comply, resulting in a classic problem of parasitism.
In addition, environmental protocols can be criticized for scientific insecurity or, at the very least, for a lack of synthesis of scientific information that can be used to “block interests and do harm.”  This can now almost be seen as an excuse, defined as skepticism about climate change. MEAS are state-to-state agreements that can take the form of a “soft-law,” which establish non-binding principles that parties must consider when taking action to address a particular environmental problem, or “hard-law,” which set legally binding measures to achieve an environmental goal. . . .
