The world economy is constantly undergoing changes; these transformations affect the tourism industry in general and the development of tourist destinations in particular. The processes that are taking place today are related to the digitization and environmentalization of processes taking place at all levels: from the activities of individual tourists, tourism enterprises and destinations to world tourism. The systemic approach to these changes is based on gradual increase in the impact of digital innovations on economic, social and environmental processes. The purpose of the article is to analyze the impact of the introduction of digital innovations on the development of various areas of management. To achieve this goal, the concept of environmentalization of the economy was clarified. Modern digital innovations that influence the environmentalization of tourist destinations have been monitored. The authors' approach to assessing the mutual impact of digitalization on the environmentalization of tourist destinations is presented using the matrix method, which allows monitoring at the regional or national level. The tourist destination digitalization index has been adapted, taking into account the costs of environmental activities through digital innovation. Application of this approach will enable regional and federal authorities, tourism management and business owners in the tourism and hospitality industry to improve the efficiency of environmental activities, provide competitive advantages to tourist areas, and simplify adaptation to changing environmental conditions.
