Organic agriculture is becoming an increasingly significant segment of agricultural production, providing a sustainable alternative to conventional methods. This thesis explores the challenges and opportunities faced by accredited control bodies in the process of monitoring and certifying organic products in Croatia. The main emphasis is placed on adapting to new technologies, harmonizing with European regulations, and maintaining the trust of consumers and producers. Key challenges, such as low digital literacy among users and frequent regulatory changes, were analysed through interviews with representatives of control bodies, as well as opportunities, such as expanding into new areas of accreditation and improving business through modern technologies. The results show that the challenges are mostly related to adapting to the requirements of new legislation and the need for user education, while opportunities lie in expanding accreditation areas and enhancing cooperation with international institutions. The introduction of modern technologies has been identified as a significant, but not critical factor for the efficiency of certification. This research emphasizes the importance of continuous education and transparency in the work of control bodies in order to ensure the sustainability of organic production in Croatia.
