Entry last updated on 21 October 2025

SUSTAYNR is a rating agency that provides sustainability data on products, enabling shoppers to make better-informed purchasing decisions.

Our core product is the ESG score – a standardized measure that objectively compares the sustainability of products on a scale of 0 to 100. This allows online shops and procurement systems to sort products by sustainability – just as easily and simply as filtering by price, manufacturer, color, and other selection criteria.
