An increasing number of companies is becoming aware that only long-term thinking based on the respect for the environment (natural and social) can provide long-term success on the market. Since corporations have a particularly large impact on the environment, it is of utmost importance that their management opt for sustainable development. In order to make quality decisions in the short and long run, it is essential that the management have all the relevant information. Strategic accounting, especially its subsystem sustainable accounting, is a valuable source of information from internal and external sources. It is for this very reason that new instruments, methods and techniques of strategic accounting are being developed in both theory and practice, which contributes to the quality of information and provides a tool for measuring the realization of strategic goals and for reporting on the level of sustainable development. The problem is the absence of standardized reporting on sustainable development and the unwillingness to do such reporting when it is not required. Various initiatives (GRI guidelines, the Global Compact, the EU Guidelines ESG, CSR Index, etc.) have appeared worldwide, Croatia included, with the aim of improving the reporting on sustainable development, as well as its credibility, so as to provide higher quality information for all stakeholders. This paper researches the level of reporting on the sustainability of Croatian companies so that the results based on successful practice, as well as its theoretical premises, could be applied while developing a model of managing the sustainable development of a tourist destination which at the same time leans on corporate managing principles. In Croatia the practice of sustainable development is not yet at a satisfactory level but in comparison with some previous studies, it does show a positive trend. Major companies, predominantly exporters or those that are a part of multinational corporations, however, already have a high level of sustainability reporting. The economic component of sustainability development is still what interests Croatian managers the most. Very few of them implement the procedures and processes aimed at environmental protection more than the legislation requires, while the social component is being increasingly recognized. It is possible to manage the sustainable development of a tourist destination by implementing the optimal practices of corporate management, which means that a destination’s management need to have access to all the relevant information from both internal and external sources in order to make quality long and short-term decisions. Sustainability accounting has the task of using the instruments and methods of strategic accounting to ensure quality reports about the achievement of the destination’s strategic goals and its level of sustainability.
