World’s Best MEPS: Tracking Leaders in Appliance Energy Efficiency Standards

The World’s Best MEPS Toolkit by CLASP is a comprehensive benchmarking tool designed to evaluate and compare the stringency of Minimum Energy Performance Standards (MEPS) for six high-impact appliance categories: lighting, air conditioners, refrigerators, electric motors, water heaters, and space heating equipment. It assesses MEPS across ten of the world’s highest carbon-emitting economies—such as the U.S., China, the EU, and India—against international best practices and targets like those from the United for Efficiency (U4E) initiative. The toolkit identifies which economies are leading, lagging, or approaching optimal efficiency thresholds, offering a clear picture of global progress toward energy-efficient appliances
