According to Mastercard, “the Mastercard Sustainable Materials Directory aims to help issuers offer more eco-friendly cards to consumers” and they have issued a sustainability badge to identify cards that have been certified through the program as meeting current industry benchmarks. CPI encourages Mastercard issuers purchasing Second Wave and Earthwise rPVC cards to add the Mastercard Sustainable Card Badge to their debit or credit cards. Since 2020 CPI has also been a proud member of the Greener Payment Partnership (GPP) formed by Mastercard and other major card manufacturers with a goal to reduce first-use PVC plastic in card manufacturing. In January 2023, the GPP collectively authored A Guide to Issuing Sustainable Cards.
