In 2003, CalPortland was approached by the US Environmental Protection Agency’s (EPA) ENERGY STAR® programme, recruiting it to become an ENERGY STAR partner. The ENERGY STAR partnership provides a variety of tools for assisting with the building and operation of an effective energy-management programme. This programme is officiated by the building of a proper structure, as defined by the ENERGY STAR assessment matrix, defining a management structure, tracking and monitoring energy, and recognising energy-management achievements.
