can help to verify that the energy management system is functioning properly and generating the planned results. The processes are monitored with regard to legal and other requirements (customer requirements, internal policies) as well as to the objectives of the energy management of the organization. The results are documented and reported to top management. Act: The top management prepares a written valuation based on the internal audit. This document is called the management review. The results will be evaluated on their performance level. If necessary, corrective or preventive actions can be initiated. Energy-relevant processes are optimized and new strategic goals are derived. Certification Certification proves that the energy management system meets the requirements of ISO 50001. This gives customers, stakeholders, employees and management more confidence that the organization is saving energy. It also helps to ensure that the energy management system is working throughout the organization. Another advantage of a certification is its emphasis on continual improvement. The organization will continue to get better at managing its energy. Additional cost savings can be generated over several years. Furthermore, certifying an organization shows your public commitment to energy management. UKAS, the certification bodies' accreditation scheme in UK, accredits certification bodies to carry out certification of business energy management systems to ISO 50001. In July 2018, there were 15 UK bodies with the necessary accreditation to carry out independent audits and issue Energy Management Systems Certification to ISO 50001. Impact ISO reported that the standard was warmly received by the market when it was first published. To the end of January 2012, around 100 organizations in 26 countries had already achieved certification to ISO 50001. ISO also listed several users who had reported significant early cost savings and benefits. In China, Delta Electronics, a provider of power and thermal management solutions, reported reducing power consumption by 10.51 million kWh as compared to the same period in 2010. This is equivalent to a reduction of 10.2 thousand tons of carbon emissions and a saving of CNY 8 million ($1.2m). In India, the Dahanu Thermal Power Station in Maharashtra expected to accrue annual savings of about INR 96.4 million ($1.7m) from raised energy efficiency and management. In Austria, the municipality of Bad Eisenkappel, with 2,400 inhabitants, expected its consumption of energy to be reduced by nearly 25 per cent, with the main savings achieved by updating the waste water plant and reducing energy consumption
