ISO 50001:2018 Energy Management Systems
TQS conducts certification audits for ISO 50001:2018, evaluating your energy management system for performance, consumption controls, greenhouse gas reduction, and alignment with sustainability objectives.
What is ISO 50001?
ISO 50001:2018 is the international standard for energy management systems (EnMS). It sets out requirements that enable organisations to establish policies, set targets, and use data to drive decisions about energy consumption. Any organisation that relies on significant energy inputs -- whether in manufacturing, commercial property, logistics, or public services -- can pursue ISO 50001 certification to demonstrate continuous improvement of its energy performance.
During the audit, TQS auditors evaluate benchmarking of energy use, measurement and documentation of improvements, and reporting of projected greenhouse gas (GHG) reductions. The standard is directly relevant to organisations preparing for CBAM compliance and broader sustainability reporting. TQS conducts ISO 50001 certification audits working with ASCB, EIAC and IAF, with certificates issued by QRS.
