Compte CO2 is a climate-focused financial service that aims to help households reduce emissions through everyday payments and greener projects. Its central idea is the “green euro,” a unit of money linked to a reduction in CO2 emissions. The company says this approach can direct money toward a less carbon-intensive economy and reward actions that lower household emissions.

Customers can use a CO2 payment account and card, supported by an iOS and Android app. The app offers real-time balance updates and transaction notifications, contact-based money transfers, and controls for card limits, PIN settings, security options, and access methods. The service also encourages users to reduce emissions at home or in transport by replacing high-carbon equipment with lower-carbon alternatives.

To support eligible projects, Compte CO2 offers a carbon bonus paid into an account, subject to a loyalty condition, and loans advertised at around 0.5%. Its website also explains how green euros work and provides articles, customer support, and information about the company.
