H+K Sweden worked with Doconomy and RBK Communications to create DO Black: a carbon emission limit credit card that is an innovative solution addressing the climate crisis. It’s the first card with a CO2-emission limit, stopping you from overspending, not based on available funds but on the impact caused by your consumption.

The innovation combines three functions. The ability to measure the impact of every transaction (Åland Index), the set CO2-emission limit calculated per country/capita, and the payment system integration of CO2-emission limit overriding the accounts financial credit level.

The technology blocks transactions exceeding the CO2 limit, disables the credit card and notifies the cardholder. Take a look at the video below to find out more.
