One of the main objectives of the economic policy of the European Union is to reduce the differences in the development levels of its member states or a process of real convergence to ensure balanced and sustainable economic development and growth in the EU countries. Each country strives to contribute to its prosperity. The authors analyse and compare the dynamics of green economy development in the EU countries in the period 2015 -2019 to clarify whether there is convergence or divergence, and this way, answering the question of whether disparities in the green economy development between the EU member states increase or decrease during this period. The study used logical analysis and synthesis, monographic and analytical research of economic, theoretical, and empirical sources (at the international level), statistical analysis methods, Barro regressions, and a cartographic method.
