Case Study
3M cuts energy costs by 15.2% with ISO 50001


3M Company, the US Chemicals company, implemented a successful energy management system (EnMS) at its Brockville production plant in Canada. In 2012, the Brockville plant obtained certification of the ISO 50001 global EnMS standard.

Accredited certification has achieved significant operational cost savings. 3M’s Brockville plant achieved a 15.2% improvement in energy intensity relative to 2010 since the EnMS was formally set up.

This was made up of:

  • an overall 3% energy intensity improvement per year
  • a 12% reduction in the energy use of its compressed air system.
  • a 30% energy cost reduction per unit of product ($/m2 ) since the EnMS has been implemented
  • a 42% energy intensity reduction (BTU/m2) since November 2011
