Business progress and human development are linked to the efficient management of energy resources. The research in this paper contributes to the generalized application of good practices that reduce the vulnerability of companies. The research focuses on energy efficiency through comprehensive management systems (CMS), and “thought based on risks and opportunities”, considering the discussion about the revision of ISO 50001:2018, the basic approach of the model and the route to implement CMS for quality, safety and health in the workplace, environmental management, energy efficiency, and other risk components. This implementation route, with the acronym CMS QHSE3+, places special emphasis on the functions of strategic planning, operational and risk management, and controls, as well as on deliverables and references to examples, templates, standards, and documents, to facilitate its application general in small and medium enterprises and in the management of energy efficiency.

The future of business development relies on the effective management of risks, opportunities, and energy and water resources. Here, we evaluate the application of best practices to identify, analyze, address, monitor, and control risks and opportunities (R/O) according to ISO 31000 and 50000. Furthermore, we shed light on tools, templates, ISO guides, and international documents that contribute to classifying, identifying, formulating control, and managing R/O parameterization in a comprehensive management system model, namely CMS QHSE3+, which consists of quality (Q), health and safety (HS), environmental management (E), energy efficiency (E2), and other risk components (+) that include comprehensive biosecurity and biosafety. By focusing on the deployment of R/O-based thinking (ROBT) at strategic and operational levels, we show vulnerability reduction in CMS QHSE3+ by managing energy, efficiency, and sustainability.

Business progress and human development are linked to the effective management and saving of energy resources. The ISO 50000 family of standards provides practices for the utilization, savings, efficiency and continuous improvement in energy performance, while the ISO 50001 establishes the requirements for an energy management system (EnMS). This document presents i) the main topics of the ISO 50001:2018 and other areas not included in its review; ii) the need for organizations to have a comprehensive model with a risk focus for the rational implementation of management systems that fulfil the practices of energy efficiency, in conjunction with quality, safety, health at work and environmental management, among others; iii) the proposed focus for the conceptual model and the implementation route of a comprehensive management system, "QHSE3+" (Q = quality management (ISO 9001: 2015), HS = health and safety at work (ISO 45001: 2018), E = environmental management (ISO 14001: 2015), E2 = energy efficiency (ISO 50001: 2011) and + = other components of risk), which contributes to the sustainable success of organizations by reducing the vulnerabilities and risks associated with the categories in the acronym QHSE3+..
