MEPS and energy labels, if well designed and implemented, are among the fastest and most effective approaches to transition markets toward more energy-efficient products. While many countries have MEPS and/or labels for refrigerating appliances, few developing and emerging economies have them for commercial refrigeration equipment. Inadequate MEPS and labels leave markets vulnerable to being dumping grounds for products that cannot be sold elsewhere. These Guidelines address the following aspects of commercial refrigeration equipment: - energy efficiency and functional performance, - product information reporting and labelling, - demonstration of compliance, and - market surveillance and enforcement.
