Abstract
The article explores the use of sustainability index ratings as key tools for establishing mechanisms of interaction between government authorities and the public in implementing the concept of sustainable development. It analyses trends in civil society both globally and in Ukraine. The study examines quantitative and qualitative indicators of public participation in societal processes, as well as indices that could improve the quality of information support for civil society organisations. The article discusses the methodology of international rankings regarding the sustainability of civil society. It also investigates the characteristics of civil society organisations and compares the effectiveness of the activities of government bodies and institutions with those of public associations that carry out similar tasks in the social, economic, and environmental spheres. Various scientific approaches to evaluating the activities of non-commercial sector entities are analysed. The importance of applying a program-targeted approach to the accounting and analytical support of the management of civil society organisations is justified, as this could become a tool for implementing Ukraine’s national strategy for promoting the development of civil society. A system of performance indicators is proposed, taking into account the environmental, social, and economic orientation of organisations. Additionally, the application of expert assessments in evaluating the activities of a public organisation under conditions of uncertainty is demonstrated.
