ISO 50001 is an internationally recognized standard for energy management systems, to help companies manage and continually improve their energy use in a systematic manner. It has proven to increase energy efficiency, reduce costs, improve competitiveness and reduce greenhouse gas emissions. Since its implementation in Canada (2011), ISO 50001 has helped companies save up to $2M per plant in energy costs. The Office of Energy Efficiency leverages and enhances ISO 50001 uptake by industry nationally, in collaboration with other levels of government. In June 2016, at the San Francisco Clean Energy Ministerial (CEM7), Canada, along with Mexico and the U.S., sponsored the Energy Management Campaign: A Drive to 50,001 Energy-Saving Partners. The Campaign was endorsed by fifteen CEM member countries and a number of private sector and international stakeholders.We continue to work trilaterally to identify areas of cooperation to meet a North American target and to build capacity for greater uptake of ISO 50001. This includes joint development of training and certification programs, case studies showcasing best practices and business benefits, coordination of technical assistance to industry, recognition and awards programs, and financial support for energy management systems implementation. Finally, in collaboration with other ISO member countries, Canada (through NRCan) is a member of ISO/Technical Committee 301 (Energy management and energy savings), actively engaged in efforts to update and improve the standard and its reach worldwide. In 2018, NRCan's funding incentive to implement ISO 50001 was expanded beyond the industrial sector to the certification was expanded to include the commercial and institutional buildings C/I sector.
