Die Swisscom Climate Challenge: MOTIONTAG Technologie hinter der Klimaschutz-App von Swisscom, Postfinance, Migros Pioneer Fund und EnergieSchweiz



Meeting the global goal of cutting CO2 emissions roughly in half by 2030 and ensuring climate neutrality by 2050 is a major challenge for all of us. In this context, Swisscom has launched the Swiss Climate Challenge initiative in cooperation with Engagement Migros, Energie Schweiz, and the South Pole. It aims to raise awareness and motivate the population to use more climate-friendly modes of transport. To do this, the company needed a technology that would make it possible to track participants’ mobility patterns and subsequently calculate their CO2 emissions.


Die Lösung mit Hilfe der MOTIONTAG Technologie


MOTIONTAG’s SDK solution was integrated into the existing Swiss Climate Challenge app and tracks the users’ mobility behavior via location and movement data that the smartphone automatically logs after an active opt-in. The advantage of the app is that it can be used not only by Swisscom customers. 


In addition, the solution helps app users to learn about their behavior concerning the climate in a playful way and to compare Their performance with that of others. A reward system provides incentives to improve one’s carbon footprint. Users collect so-called Green Coins and Green Points, which they receive by achieving certain challenges. Some of these are activated directly after opting in, while others require a separate registration in the corresponding area for challenges.


The Green Points are received by the user after completing the task and offer the opportunity to compare themselves with others. They have no material value but can support a charitable project after all participants have been added. This is financed by the initiators of the Swiss Climate Challenge or additional sponsors.


Contrarily, the Green Coins have a material value and are provided by sponsors. Here, a task is defined for certain groups, e.g., a company, a city, or a municipality, and a monetary amount is provided by the sponsor for the solved task.


Herausgegeben werden die Green Coins von der PostFinance AG und haben den Wert von einem Schweizer Franken. Sie können auf dem Marktplatz für nachhaltige Produkte, Dienstleistungen oder Spenden eingelöst werden. Das Ziel hier ist, größere Gruppen für ein klimafreundliches Verhalten zu belohnen.


How does it all work in the background? To register, users provide either their email address or mobile number to ensure re-identification. Only after the opt-in has been granted the location and movement data can be accessed. The information is recorded and stored pseudonymously on the MOTIONTAG servers and enables MOTIONTAG to evaluate the mobility behavior and CO2 emissions of the user. The distances traveled per the mode of transport, the CO2 emissions and the impact on the climate are calculated using the pseudonymized data and stored in the user’s app. In addition, Swisscom conducts a further data assessment.


Der Nutzer hat außerdem die Möglichkeit weitere klimarelevante Daten freizugeben, damit er sich mit anderen Teilnehmenden vergleichen kann und somit einen weiteren Ansporn hat, seine Mobilität klimafreundlicher zu gestalten. Dabei werden für jeden Kontakt die Mobilfunknummer und eine Identifikationsnummer in die App-Cloud von Swisscom hochgeladen und pseudonymisiert gespeichert. Um den Vergleich mit anderen Teilnehmern zu ermöglichen, ist diese Vorgehensweise nötig. Die Entscheidung zur Teilung der Daten liegt allein beim Nutzer.


Wichtig ist, dass es bei allen erfassten Daten keine Möglichkeit zur Rückverfolgung auf einzelne Personen gibt.




Es sollten in der Challenge 100.000 Green Points gesammelt werden, am Ende kamen sogar 165.000 zusammen. Somit spendete Swisscom CHF 100.000 an zwei Klimaprojekte.
