ISO 50001 offers tremendous potential to contribute to international, national, and corporate energy and climate emissions reduction goals.


The ISO 50001 Impact Estimator Tool (IET 50001) empowers governments and organizations to estimate energy and emissions savings potential from the implementation of ISO 50001 in a country or region.


A scenario with 50% of projected global industrial and service sector energy consumption under ISO 50001 management by 2030 would generate cumulative primary energy savings of approximately 105 EJ, cost savings of nearly US $700 billion (discounted to 2016 net present value), and 6500 million metric tons (Mt) of avoided CO2 emissions. The avoided annual CO2 emissions in 2030 alone are equivalent to removing 210 million passenger vehicles from the road.

The report contains more details about the methodology and its assumptions.

Use the Tool Today!

  • Access the IET 50001 to calculate avoided energy consumption, energy cost savings, and associated emissions reductions in your country. Send an email with your contact information (name, affiliation, and email address) to to receive the tool. 
  • Once you’ve completed the IET 50001, use the Reporting Template to share the results with policy-makers, stakeholders, and others. 
  • For additional instructions, view the IET 50001 User Guide and Methodology.
  • The ISO 50001 Global Impacts Research network developed the methodology that is detailed in the report.


The annual and cumulative results generated by the tool are based on generic regional energy consumption, energy prices, percent ISO 50001 uptake and percent energy savings attributable to ISO 50001. (The default values can be overridden if more region-specific data is available.)

  • The EMWG’s ISO 50001 Global Impacts Research Network developed this methodology for use at the national or regional level to predict, quantify, and demonstrate the value of ISO 50001.
  • The EMWG supports the Energy Management Campaign that aims to achieve 50,001 global certifications to ISO 50001 by 2020.
  • Complementary to the IET 50001, the EMWG has also developed a tracking tool, the Energy Performance Database (EPD), which is designed to collect quantitative data that will provide a more detailed understanding of EnMS drivers, barriers, and benefits.
