Climate changes are one of the results of human interaction with the surrounding environment. The result is an increase in global warming of our planet, which has many impacts on the environment, animals and humans. Therefore, the international action agenda was interested in including the issue of combating climate change, especially in an organization at the United Nations and in many conferences that emerged from the United Nations Framework Convention to confront climate change, the most recent of which was the Conference of the Parties held in Sharm El-Sheikh in its 27th session to confront the phenomenon of climate change Cop27, and its release to the world. With the aim of "moving from the planning stage to the implementation stage." Perhaps the most important feature of combating climate change in international action is that it is originally based on framework principles, that is, in the concept of general international law, which are not binding. In addition, its effectiveness is determined according to the principle of good faith in implementing international obligations, which depends on the will of its parties. Therefore, in this scientific paper, we address two basic ideas that determine the contemporary and future international legal system to combat climate change. They are preceded by an introductory study in which we know what is meant by climate change and the development of the legal system. To combat it. The first: the idea of carbon tariffs as one of the most important ways for the international community to combat climate change. We will examine its meaning, its role, and evaluate this method in the coming period and its feasibility. The second: We address the idea of establishing an independent international organization concerned with combating climate change, and which will be responsible for following up on the commitments of its members towards combating climate change.
