International standard ISO 50001 for energy management systems

General information on ISO 50001

There is now a new international standard for energy management systems. On June 15, 2011, ISO 50001 was published. The objective of the standard is to continually improve the energy performance of an organization or a company, so that costs can be lowered and greenhouse gas emissions and other environmental loads reduced.

The ISO international describes the requirements to introduce, implement, maintain and improve an energy management system. The content of DIN EN 16001 with identical wording has been included in ISO 50001.


An energy management system in conformance with the ISO international can be implemented, independent of existing management systems, as well as integrated into existing management systems. As the ISO 50001 regarding the structure lines up with the DIN EN ISO series of standards ISO 9001 and especially ISO 14001 for environmental management systems, the latter is possible without any high associated costs. The currently valid and relevant laws, regulations and ordinances must be observed.

Tax advantages

For "energy intensive operations" according to 2003/96/EC, the introduction of a certified ISO 500001-compliant energy management system is also recommended for tax reasons. In Germany, from 2013, tax incentives for the energy and electricity tax (ecotax) in industry is firmly coupled to implementing an energy management system. 2011/2012 can be used as a transition phase for the introduction. Here, Siemens is admirably positioned as supplier of high-efficiency products and integrated solutions.
