The proposals are based on an analysis of the current state and methodologies of corporate risk management with an emphasis on management according to internationally recognized ISO 3100X standards and their revision, as well as the requirements of revised ISO standards for quality management, environment, safety, etc. related to risk management. The Deming cycle (Plan-Do- Check-Act) of continuous improvement is a methodological tool for building a management system, whether for a partial aspect or integrated, which greatly facilitates the integration process. Significant support for the integration of management systems is a unified element structure of the latest revisions of ISO standards according to Annex SL for quality ISO 9001, environment, ISO 14001, occupational health and safety ISO 45001, information security ISO 27001, but also others. When implementing management systems according to these standards, it is recommended to use the latest ISO standard 31000: 2019 Risk Management - Guidance in connection with the management of individual risks. Although this standard does not have a 10-chapters structure according to Annex SL as well as other standards, it is fully integrated into the system. It has 6 chapters and chapters 4. Principles, 5. System, 6. The process contains recommendations that can be integrated with the requirements of the chapters of the ISO standards for environmental management, quality, safety and health at work, health and safety, information security. The identification and evaluation of aspects of impacts and risks is an input to building management systems of an organization according to internationally recognized standards, whether for partial aspects or an integrated system. The most important aspects impacts and risks, whether technical, economic, environmental, safety, information and others are reflected in the management system in policies and objectives. In this context, it is useful to draw up a Register of Aspects, Impacts and Risks for organizational processes, and if it is an integrated management system, an integrated register is needed. As part of our research, a generally applicable guide to the preparation of a more exact integrated register was proposed as a basis for building an integrated management system. The register form includes 10 columns with their specification and quantification and was applied in the operating conditions of the Vojany thermal power plant in the implementation of the quality and environmental management system according to the relevant international standards. At the end of the paper, the presented solution specifies possible benefits from the implementation of an integrated management system built according to internationally recognized ISO standards.
