Aim. Comparative analysis of the progress of achieving sustainable development by Maghreb countries (among them Libya, Tunisia, Algeria, Morocco, Mauritania) according to the indices developed by international organizations and scientific institutions, as well as ranking the countries according to the level of sustainable development in the region.Objectives. To analyze the regulatory framework governing sustainable development in the Maghreb countries; to assess the level of sustainable development of the countries under consideration according to international environmental, social and economic indices in 2018–2023; to apply a universal methodology for assessing sustainable development based on basic statistical data of each country; to identify common achievements and unique challenges faced by countries in the process of implementing sustainable development programs.Methods. The analysis is based on the comparison of statistical data, publications and reports of international organizations on the success of the implementation of sustainable development programs in the Maghreb countries. Comparative and analytical approaches to assessing the level of sustainable development were applied, and attention was paid to factors affecting successes and obstacles to achieving sustainable development.Results. Maghreb countries are at different levels of sustainable development. The article traces the differences in the countries’ strategies for implementing national sustainable development programs. The analysis of the level of sustainable development in Maghreb countries showed that Morocco has the highest position. Libya has the lowest level of sustainable development. The poverty rate in the region is decreasing, although in Libya, it remains high. Countries are showing progress in renewable energy development, with Morocco in particular implementing solar energy programs. Despite the successes, the countries face significant challenges. Inequality in access to resources and income, along with high unemployment, especially among youth, remains a pressing problem in the region. Political instability in Libya, non-cooperation between Morocco and Algeria hinder economic development and the realization of the Sustainable Development Goals.Conclusions. Regular monitoring of the level of sustainable development in the Maghreb countries, as well as timely adjustment of actions, serves as a necessary step to achieve prosperity and well-being in the region. Despite many challenges, Libya, Tunisia, Algeria, Morocco and Mauritania have great potential for sustainable development. However, realizing the Aim. requires considerable effort, political will and effective cooperation, both within the region and internationally. It is necessary to continue to invest in development, strengthen regional cooperation and utilize innovative technologies to achieve a sustainable future.
