Abstract: The subject of this research is the legal regulation systems for reducing greenhouse gas emissions in Russia and France. In this article, the Author examines the characteristics of the legal regulation systems for reducing greenhouse gas emissions and provides a comparative legal analysis, assessing their level of anthropogenic impact. The Author reveals the existing legal regulation, analyzes the existing positions in the legal literature regarding the pros and cons of the chosen strategy for limiting greenhouse gases, and the prospects for its implementation. Within the framework of this article, the Author addresses the issues related to the implementation of domestic and French strategies for combating greenhouse gases and concludes on the most significant and effective methods for reducing greenhouse gases while touching upon the supranational European regulatory level. In preparing this research, the author employed formal-legal, comparative-legal methods, as well as induction, deduction, and analysis methods. The main conclusions of the research include the Author's findings on the most effective and rational methods for combating greenhouse gas emissions, as well as conclusions regarding the problems associated with the implementation of the relevant strategies for reducing greenhouse gas emissions. Thus, the Author identifies monitoring and measurement systems for greenhouse gas emissions as some of the most important tools for reduction, while also highlighting a method characteristic of the Russian Federation, which is the use of natural ecosystems. In his research, the Author also evaluates the necessity of introducing a carbon market in the Russian Federation, analyzes the experience of European Union countries, and concludes about the enormous commercial potential and prospects of introducing this market in the Russian Federation. The novelty of the research lies in the comparative legal analysis of the systems in Russia and France in this area.
