The ENERGY STAR® is the national symbol for protecting the environment through superior energy performance. To qualify for the award, a plant must score at least 75 of a possible 100 on the Energy Performance Indicator (EPI), used by the EPA to measure energy efficiency in cement plants. In addition, the plant must have a three-year history of environmental compliance.
