In 1999, the European Commission established different efficiency classes for electric motors to reduce energy consumption and to create awareness among various industries to the importance of a more sustainable environment. These efficiency classes were called the EFF standards. However, in 2008 these EFF standards changed to the current IEC standards for electric motors to overcome the international inconsistencies in regulations between electric motor standards and efficiency classes. For example, the US established the NEMA standards for electric motors, which differed a lot from the EU standards. These standards were set by a new commission called the International Electrotechnical Commission (IEC).
