Doconomy: Do Black
Doconomy, a Swedish fintech startup, tasked Rbk Communication with creating a radical solution to help consumers reduce their carbon footprint. They needed to move beyond awareness into behavioral change, targeting conscious spenders who wanted to align their consumption with the Paris Agreement goals but lacked the tools to track their real-time impact at the point of sale.
Creative Idea
A credit card that blocks transactions once the user exceeds their personal carbon budget.
Doconomy launched the world's first credit card with a carbon limit instead of a financial one, turning every transaction into a climate decision by physically blocking purchases once the user's CO2 budget for the year was reached.
The Credit Card That Stops Spending for the Planet
From Exhaust to Ink
To ensure the physical product matched its radical message, RBK Communication utilized Air Ink for the card's printing. This specialized ink is created by capturing carbon soot from vehicle exhausts and industrial chimneys, effectively turning pollution into a design tool. The card itself was manufactured from bio-sourced materials, moving away from traditional PVC to minimize the environmental footprint of the hardware.
A Shift to Impact Tech
The campaign’s success fundamentally altered Doconomy’s business trajectory. While the "DO Black" card was eventually discontinued in 2022, it served as a high-profile proof-of-concept that transformed the startup into a B2B powerhouse. The Åland Index, the underlying technology developed with Ålandsbanken, became a banking industry standard. It is now utilized by global giants like BNP Paribas, Klarna, and Standard Chartered, while Mastercard integrated the carbon calculator for its 2.9 billion cardholders worldwide.

The Paris Agreement at the POS
Creative leaders Mathias Wikström and Johan Pihl designed the card to flip the traditional banking model. Instead of rewarding high spending with points or increased credit, the card enforced a "carbon budget" aligned with the Paris Agreement goal to halve emissions by 2030. As CEO Nathalie Green noted, the tool was designed to remove excuses by making the urgency of the climate situation tangible at the point of sale.
Viral Conspiracy Theories
Years after its 2019 launch, the campaign took an unexpected turn in the cultural zeitgeist. In 2022 and 2023, it became a focal point for "Great Reset" conspiracy theories. Misinformation spread across social media, with some claiming the card was a tool for totalitarian government control over personal travel and diet.
