Rio Tinto, a metal and mining company, has launched START, a sustainability label for aluminum based on blockchain technology. According to Rio Tinto, START will help customers meet consumer demand for transparency about where and how the products they buy are made. The aim is to enable end users to make informed decisions about the products they buy in order to contribute to a sustainable future and to differentiate end products based on their environmental, social and governance qualifications.

Customers receive a digital sustainability label – similar to a nutrition label on food and beverage packaging – with secure blockchain technology. It contains important information about the location where the aluminum was responsibly produced and covers 10 criteria: carbon footprint; Water consumption; recycled content; Energy sources; Community investment; Security deposit; Diversity in leadership; Business integrity; Legal compliance; and transparency.

The START sustainability label is now available for aluminum purchased from Rio Tinto’s global operations.

Via START, Rio Tinto will also provide technical expertise through a sustainability advisory service and support to customers who want to build their sustainability offerings, evaluate and improve performance, support procurement goals and gain access to green finance.
