The City Of Lahti Enables Personal Carbon Trading

How do you involve your citizens in becoming carbon-neutral and give them control in achieving this goal? The Finnish city of Lahti, European Green Capital in 2021, set out to do just that. Its goal is to be a carbon-neutral city by 2025, meaning ten years earlier than, for example, the Finnish state and most other cities. In this blog, we describe how a billing platform became a key instrument to give citizens control.

Customer-Centric Service For The Good Cause

The city of Lahti wanted to involve its citizens in an experiment to reduce their carbon footprint. They decided to develop a system that enables personal emissions tracking, crediting, and trading mechanisms for personal emissions. Lahti citizens using the system can benefit from reducing their emissions from mobility. They can receive various incentives on the platform marketplace if they reduce emissions.

CitiCAP: the Carbon Trading platform project

The system called CitiCAP, automatically identifies what is the mode of transportation of its user and tracks emissions from mobility. Mobility is tracked by a mobile app that can identify the means of transport using an intelligent algorithm. The data is sent to the billing platform which converts the data to emission credits and maintains user-specific credit balance. The rating and billing platform also maintains a budget for the user. If the user remains below budget, virtual credits are accumulated and exchanged for various products and discounts on the application marketplace.

Good Sign as the flexible engine for the carbon trading platform

For the service, Lahti needed a modern and flexible platform to enable carbon trading. The original plan was to develop a custom platform for that specific use. However, after evaluating the capabilities of Good Sign, Lahti was convinced by its flexibility and the ability to enable fast to market. The Good Sign platform with its standard configuration tools was chosen.
