The article updates the issue of the transition to a green economy. It emphasizes that the green economy policy faces a number of contradictions and problems that make its implementation a difficult task. The tools and mechanisms for implementing the transition to a green economy are substantiated, taking into account the theoretical foundations of the ecological economy. These include economic, regulatory, and informational tools and international/interregional cooperation. The interpretation of the concepts of green economy and green growth is presented. The tools and mechanisms for implementing the transition to a green economy in the context of the Green Growth Strategy are defined, namely: economic, regulatory, and informational tools, international/interregional cooperation, the development of green innovations, and raising the environmental awareness of the population. The essence and main tasks of the European Green Deal are considered. Attention is focused on the consideration of financial instruments, the use of which will make it possible to mobilize the necessary investments in order to transform various sectors of the EU economy to reduce emissions into the atmosphere. The necessity and possibilities of the transition to a green economy in Ukraine are substantiated. Directions and measures for increasing the efficiency of ecological development of the regions of Ukraine are proposed: development of new and improvement of existing tools, introduction of incentives for the use of ecological development tools, raising awareness and involvement of the public in the processes of ecological development, strengthening the institutional capacity for the implementation and monitoring of environmental policy, and minimizing threats to agriculture. The article notes that the green economy is still a relatively new phenomenon, so many researchers and political circles oppose the implementation of its initiatives, including economic liberals, conservatives, and certain industrial groups. The main reasons for non-acceptance of a number of initiatives of the European Green Course by the farmers of European countries are identified.
