The Global Efficiency Medal (GEM) competition, a cornerstone activity of the Super-efficient Equipment and Appliance Deployment (SEAD) Initiative, is an awards programme that encourages the development, production and sale of super-efficient products. SEAD is a voluntary multinational government collaboration of the Clean Energy Ministerial. This winner-takes-all competition recognises energy-efficient products, guides purchasers towards energy-efficient product choices, and demonstrates the levels of energy efficiency achievable by commercially available and emerging technologies. It is designed to complement existing national and regional appliance and product labelling programmes, and to advance comparable and transparent international test methods that support minimum energy performance standards. This paper summarises the findings from the fourth Global Efficiency Medal competition, which focused on super-efficient lighting products in four regions around the world.
