89 :Credit card as personal CO2 calculator

Problem:

There were a total of 1.06 billion credit cards in 2017 and the projection for 2022 is close to 1.2 billion. Cards are made of several layers of plastic laminated together. The core is commonly made from a plastic resin known as polyvinyl chloride acetate (PVCA). This resin is mixed with opacifying materials, dyes, and plasticizers to give it the proper appearance and consistency. This bodes badly for landfills.

Solution:

A personal CO2 calculator.


In 2008, Discover launched a “green” credit card made of biodegradable PVC, 99 % of which can be absorbed back into the environment given the right conditions. Discover contended that, with exposure to soil, water, compost, and other microorganisms, the card will degrade completely within nine months to 5 years.

But can a biodegradable card do more than facilitate purchases? Having worked for nearly ten years in Sweden’s banking and insurance section, when Nathalie Green was faced with the inertia of large institutions to respond to the climate change emergency, she decided to leave her post and dedicate all her energy to the creation of products to accelerate the ecological transition.

Founding a company called Doconomy, Nathalie conceived “Do”, a mobile application that measures CO2 emissions from our purchases. From there on, Doconomy has progressed to the Do-Card, incorporating technology from the Ålands Bank Index, a Finnish financial tool that uses big data to match every purchase with the most accurate estimation of CO2 emissions related to its production and consumption.

Specifically, each time the card is used, its owner receives an alert that indicates the carbon footprint of the purchase. For example, at a checkout, he will know that the purchase of jeans is 70 lb (32 kg) of CO2. Those who sign up to DO will receive access to a free savings account that helps them understand their carbon footprint, learn about UN-certified climate compensation projects, and discover investment funds that have a positive impact on people and the planet.

The card itself is made of bio-sourced material and is printed with Air-Ink, which was our Solution #6  and with no magnetic strip is the first of its kind in the world. For this solution, Doconomy is working with Mastercard via their global network, reaching and levering the power of consumers all over the world and direct capital towards sustainable initiatives. In October 2020 when Mastercard launched the expansion of the Priceless Planet Coalition to support planting 100 million trees, Doconomy was one of the 33 banking partners.

What you can do: Buy and use a Do-Card and tell your friends about it.
