Treecard offers a debit card that allows users to support environmental causes through their everyday spending. The card, issued by Sutton Bank under a Mastercard license, rewards users with points for purchases, especially from sustainable brands and for eco-friendly activities like using public transport or walking. Users can redeem these points for rewards that promote sustainability, such as eco-friendly travel and refurbished tech products. Treecard differentiates itself by focusing on ethical spending and partnering with Ecosia, a search engine that plants trees with its revenue, contributing to the planting of 150 million trees globally. The goal of Treecard is to make it easier for consumers to make a positive environmental impact while managing their finances.
