Energy is critical to organizations, but often represents a significant cost – both to them and the environment.
An energy management system helps organi - zations better manage their energy use, thus improving productivity. It involves developing and implementing an energy policy, setting achievable targets for energy use, and design - ing action plans to reach them and measure progress.
This might include implementing new energy-efficient technologies, reducing energy waste or improving current processes to cut energy costs. ISO 50001 gives organizations a recognized framework for developing an effective energy management system.
Like other ISO management system standards, it follows the “ Plan-Do-Check-Act ” process for continual improvement. ISO 50001 provides a set of requirements that enable organizations to :
• Develop a policy for more efficient use of energy
 • Fix targets and objectives to meet that policy
 • Gather data to better understand and make decisions concerning energy use
 • Measure the results obtained
 • Review the effectiveness of the policy
• Continually improve energy management
 
The benefits:
ISO 50001 is designed to help your organization improve its energy performance through making better use of its energy-intensive assets. Improved energy performance can provide rapid benefits for an organization by maximizing its use of energy sources and energy-related assets, reducing both cost and consumption. ISO 50001 is used by large and small organizations all over the world. Its benefits can take many forms. For some, it is about reducing the environmental impact and enhancing reputation; for others, the aim is to drive down costs and improve competitiveness.
