Abstract: The author studied in detail the aspects of cooperation between Russia and Brazil in the field of green energy. In this context, Russia and Brazil, as countries with vast territories and rich natural resources, have a special potential for developing the green energy sector both within the framework of each country's energy policy separately and in bilateral cooperation. Both countries are expanding the possibilities of using various types of renewable energy sources, and therefore cooperation between these two states can become an important factor in promoting this direction in global realities. The countries are actively strengthening cooperation within the framework of the BRICS, because one of the relevant topics on the agenda of the association is precisely cooperation in the field of green energy and the economy. The partnership between the two countries not only contributes to achieving carbon neutrality, but also creates favorable conditions for further economic growth. The main research method is system analysis, which reveals the components of the countries' cooperation policies in the field of green energy, and the green energy of Russia and Brazil are considered separately. A geo-economic approach was also used to identify the dependencies of the development of low-carbon markets in Russia and Brazil on the common agenda of such an association as the BRICS. The scientific novelty of the study lies in an extensive analysis of cooperation between the Russian Federation and Brazil in the field of green initiatives, including the creation of low-carbon markets, the use of renewable energy sources, as well as the promotion of climate and carbon-neutral initiatives of the two countries through the BRICS. The article examines this aspect of cooperation between the two countries, since when analyzing energy cooperation between Russia and Brazil, researchers more often focus on carbon energy resources. The two countries are strengthening cooperation in the field of green innovation, creating joint projects in the field of nuclear and hydrogen energy and contributing to the sustainable development of the two countries. The countries are actively strengthening cooperation within the framework of the BRICS, because one of the relevant topics on the agenda of the association is precisely cooperation in the field of green energy and the economy. The partnership between the two countries not only contributes to achieving carbon neutrality, but also creates favorable conditions for further economic growth.

Abstract: The subject of the study is the migration situation in EU. Against the background of global socio-economic transformations, the EU is facing multifaceted problems in managing migration processes, acting as one of the most attractive areas of modern migration. Mass migration flows are a natural companion of globalization and the policy of openness promoted by many States. The purpose of this article is a comprehensive analysis of migration processes in the EU, focusing on the theoretical foundations, dynamics and current issues. Special attention is paid to the transformation of migration legislation in the EU member states in the period 2020-2023. The revealed data on new migration projects in the EU countries make it possible to trace the dynamics of changes in official EU legislation on this issue and formulate proposals for resolving the crisis situation. The methodological basis of the research is a systematic approach and the theory of multilevel management. The systematic approach was used in the work to identify the causes and consequences of the transformation of EU migration legislation within the framework of an integrated set of migration processes. The theory of multilevel management considers the issue both at the national level and at the level of the European Union. The novelty of the research lies in the development of scientific discourse on migration processes in the European Union. An in-depth analysis of migration dynamics in the EU, and as a result, the reasons for the transformation of migration legislation, expands the understanding of migration control mechanisms, and also evaluates the participation of EU member states in the formation of migration policy. The research contributes to the awareness of the interactions between migration and other socio-economic processes, which is significant for the academic community and the creation of educational programs. The practical significance of the study lies in its contribution to the formation and improvement of the EU migration policy. Based on the collected data and analytical conclusions, recommendations can be made to improve the current mechanisms of migration management, strengthen integration processes and maintain social balance.
