DO Black

DO Black is the first credit card with a CO2 emission limit that allows users to monitor the environmental impact of their transactions.

Conceived as a tool to combat climate change, DO Black combines three main functions: it can measure the carbon impact of transactions, set a CO2 emission limit calculated per country or per person, and overrides an account’s financial credit level based on the limit.

The function, although integrated into the credit card, can also be applied to existing bank accounts internationally.
