The concept of sustainable development has been widely analyzed in scientific literature and is understood as a process aimed at balancing human activities with the environment. Sustainable agricultural systems generate economic value, manage natural resources responsibly, and support rural development. Modern agricultural production, however, faces challenges across these dimensions, making their assessment essential for the long-term viability of farms. This paper introduces indicators of economic, ecological, and social sustainability for agricultural holdings, using the FADN (Farm Accountancy Data Network) database as a foundation. The structured nature of FADN allows for consistent analysis of sustainability, while additional indicators assess the impact of agricultural policy on farm performance. Together, these provide a comprehensive framework for understanding and improving farm sustainability. The main contribution of the study is the establishment of a set of feasible indicators that can be derived from the FADN database to support comprehensive sustainability assessments.
