ISO 50001:2018 EnMS standard, like any other Management System standard from the ISO, is a process-based standard, and involves all the processes in the business/system, and involves the needs and expectations of all relevant interested parties from an internal employee to an external supplier/vendor or customer or end-user or Government, or society as a whole. The ISO 50001 EnMS standard involves all the processes right from procurement to manufacturing to deliveries.


The ISO 50001 standard is specifically based upon the PDCA concept of ISO Management standards:




PLAN– The Organization must

  • Do an energy review & establish a baseline for your energy consumption.
  • Set objectives and targets you want to reach in your energy usage.
  • Develop action plans to take advantage of energy opportunities.
  • Define your Energy Performance Indicators (EnPIs).


DO- The Organization must

  • Delegate tasks to relevant team members.
  • Implement the action plans you created in the planning stage.


CHECK- The Organization must

  • Monitor your processes and measure your energy usage.
  • Check your results against the targets and objectives you set.
  • Report and communicate the results (particularly with key decision-makers).


ACT- The Organization must

  • Take actions as in Corrections, Corrective Actions and Preventive Actions including the effectiveness of Operational Controls (Mitigations, Contingencies and Strategic actions).
  • If the business hasn’t achieved, determine why and take action to fix the issues.


Implementing ISO 50001:2018 EnMS by the Organization isn’t just a way to reduce operating costs and other costs, it’s also a great way to contribute to your business’ overall sustainability plan. No true successful environmental sustainability plan is complete without a having a thorough energy consumption reduction element, though not hampering the production or other product quality-related yields, including the introduction of quality, environmental and energy key performance indicators (KPIs).


Using ISO 50001 EnMS can surely help the organization with adopting the best plan for maximizing the (if available) renewable energy sources or finding more energy-efficient equipment to complete the same tasks. Even if the organization hasn’t reached a stage where it is ready to start making those changes, using ISO 50001 EnMS will give concrete energy usage data (through documented information)- and this is mandatory, that makes for great sustainability report material and is useful during the decision-making process at all levels of Management.


ISO 50001 EnMS can also have a dynamic effect on air emissions and greenhouse gas (GHG) emissions if the organization uses it to reduce the overall energy usage or switch to more renewable sources. The Organization will be able to reduce GHGs associated with energy providers and that can make a big difference when it comes to carbon footprint reporting, both mandatory and voluntary from regulatory perspectives or individually. Also, ISO 50001 also helps to manage the energy consumption related to the entire supply chain from procurement of raw materials to design/development, to production, assemblies, to storages and deliveries. Creating a more sustainable supply chain is one of the most efficient ways of transforming your business into a more sustainable enterprise.

There is a stronger emphasis on the role of top management and management at all levels as well, as it is important to instilling an organizational culture change. It is also now aligned with ISO’s Annex SL requirements for management system standards, making it easier to integrate into an organization’s existing management systems. The most important aspect then is sustainability.


While trying to implement the sustainable clause of the Energy Management System, the organization must adopt to develop a Strategic Business Plan (SBP) at the initial stages.


The main objective of the SBP is to provide a concise and up-to-date overview of the organization’s work in a user-friendly format for interested stakeholders. The types of stakeholders to be addressed in the SBP may include:

  • The management layer of organizations and companies making a contribution to standardization;
  • Standards developers and standards developing organizations;
  • Regulators;
  • Users of standards;
  • The interested public.
  • Employees
  • Suppliers / Vendors / Contractors / Sub-Contractors
  • Customers
  • End-Users
  • Society
  • Neighbours


The SBP should provide an analysis of important business, technological, environmental and social trends in the field addressed by the work of the ISO/TC. It should also explain the linkages between these trends and the priority areas in the standards development work of the committee.


Sustainable development, energy efficiency and energy management fundamentals, a detailed analysis of the energy management systems standard ISO 50001:2018 EnMS is required to be carried out from the viewpoint of sustainable development, by the Organization. The purpose of the analysis should be to assess the effectiveness of its implementation, to identify the existence of gaps and to develop improvements capable of fulfilling the identified gaps. The effectiveness and the results of ISO 50001:2018 EnMS implementation, combined with the construction of an ideal energy management system allowed the identification of gaps/ lacunas. The contribution to the sustainable development of these gaps should be determined by the Organization. A detailed framework analysis of the identified gaps to be followed, reviewing the associated ISO 50001:2018 standard requirements and converting them into potential improvements. These are some ways wherein organizations can implement sustainable energy effectiveness.


The Organization shall strive to optimize both the environmental and energy policies in the company and takes on even greater shared responsibility for people and the environment. The careful use of resources is a key point of the Organization’s energy policy. The environmental effects and savings on raw materials and energy are taken into account to the best possible extent in the planning of processes and systems and projects resulting in ultimate product deliverables as well as during the procurement of equipment and services. The continuous collection of environmental and energy consumption data forms the foundation for comprehensive resource savings thus sustenance.


The energy conservation initiatives are part of the Management and Organization’s vision for sustainability​ with achievable goals for reducing its environmental impact for a particular period. Examples of those goals include:


  • Reduce energy intensity by 25%,
  • Promote state-of-the-art pollution control technologies,
  • Reduce spent generation by 30% and to reuse/recycle spent materials used in the relevant process to achieve zero-landfill disposal,
  • Reduce water consumption by 80%.
