Abstract

This study proposes a smart energy efficiency label (smart label) using blockchain technology to ensure secure access, traceability, validation, and certification of all information related to the energy performance of labeled equipment. The methodology involves mapping the process of using the PROCEL (National Electric Energy Conservation Program) label on a typical household appliance within the Brazilian Labelling Program (PBE), showing the application of blockchain technology throughout the process. With the PROCEL label, blockchain can document the entire lifecycle of the equipment, tracking every step until it reaches the consumer. This allows consumers to trace and verify the results of tests the equipment has undergone, make comparisons between various products, understand the ecological impact of the product's development, and ensure that the product is not counterfeit. Labels, logos, and quality descriptions reduce information asymmetry regarding product quality, providing consumers with greater confidence in their purchases. Blockchain technology addresses each of these aspects by enabling traceability, certification, verification, and security of the information presented on the equipment. The smart label holds significant potential to enhance agility, transparency, security, interoperability, auditability, reliability, and product traceability, thus benefiting both consumers and manufacturers by fostering trust and promoting the production of more energy-efficient products.
