In 2018 Doconomy launched a service called DO, a mobile banking service linked to a payment card, creating a profile of a user’s consumption-based climate impact relevant all commerce. This profile is created by applying an impact value to categorized products and services (using Åland Index). The platform allows the user to track, measure and offset their impact through a number of United Nations Certified Green Projects, while providing data driven insights to support behavior changes and take climate action through conscious consumption.

The brief was to position Doconomy with limited resources in a crowded fintech environment, as a credible and unique agent for change.

The objectives was to make Doconomy perceived as a helpful solution, resulting in awareness, user adoption and productive partnerships.


There’s a definite, data substantiated, emotional driver connected to climate change, but there’s a lack of concrete solutions and tangible tools that engage and activate consumers.

DO Black is a radical new tool against climate change. 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. Adapting 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 intention is to make a tangible solution, resulting in awareness, user adoption and productive new partnerships impacting every transaction.

This simple yet tangible idea of a CO2-emmission limit will forever change the payment solution industry. Injecting responsibility at the core of consumption.


Data gathering:

The strategy was to gather public data from UNFCCC and Our World in Data (Oxford), for a scalable solution, that created undeniable individual relevance as well as precision compliant with the regulations and restrictions in the financial services industry.

Data interpretation

Third party verification of CO2-impact per transaction provided by the Åland Index with leading ESG-data (Thomson Reuters and Sustainalytics) and CO2-emission limit per capita interpreted and verified by leading sustainability consulting expertise.

• Targeting

Strictly individual in real time.


DO Black scales with ease and CO2-limit per country is calculated with public data connected to the global platform of Mastercard.

Over 40 banks from all over the world are already in contact to discuss collaborations/white label solutions, and other credit card companies have reached out to discuss a potential collaboration to implement the idea.

Placement only in earned media and with partners communication.
