Many things contribute to the world’s carbon expenditure–including our consumer shopping habits. The problem is, most people don’t have an easy way to track their spending’s negative impact on the environment. That’s where Sweden’s Doconomy comes in. The company’s DO White credit card tracks the CO2 emissions generated from cardholder’s purchases. Released to the Swedish market in 2020, the DO White card is powered by the company’s Åland Index–a cloud-based service for climate impact calculations. With every purchase made on the card, Doconomy’s Åland Index (which partners with banks in 14 countries) calculates its CO2 impact and generates a score, which the user can then offset by buying units in UN-certified climate-friendly compensation projects in developing countries. Within months of its mid-2020 launch the DO card attracted 20,000 customers in Sweden.
