The story about the card game Climate Call (Klimatkoll in Swedish) begins at the address Doktor Bex gata 5 in Gothenburg, Sweden, in 2009. This is when David Andersson moves in with Jonas Karlén, a former football coach. David is soon hired as a PhD student at the Department of Energy and Environment at Chalmers University of Technology, where he begins conducting research on sustainable consumption. David and Jonas become close friends and run the amateur bar “Guldhedens Biblioteksbar” together, where Jonas mixes cocktails and David makes hot sandwiches. David also raises Jonas’ climate awareness by constantly pointing out when he takes too long showers, forgets to turn off the light, or eats meat for dinner.

– Energy!, says David.

– Okay!, says Jonas.

Seven years later, in 2016, Jonas enrolls in a university course titled “Games and Simulations as Tools for Learning” at the University of Gothenburg. During the course, Jonas gets an idea: a card game where players rank activities based on their climate impact. Excitedly, he shares this concept with David, who immediately starts working on it. 

A simple prototype is developed and showcased at a lunch seminar at the Department of Energy and Environment at Chalmers. Both students and professors get excited about the idea! But the real spark happens when David’s colleagues, Erik Sterner, a pedagogy and climate physics enthusiast, and Stefan Wirsenius, a world-renowned expert in climate impacts from food and land use, get on board.

The prototype is further developed and tested at middle and high schools. The students and their teachers also like the game, and David, Jonas, Erik and Stefan decide to form the company Klimatkoll Guldheden AB, with the aim of spreading the game to a larger audience.

Today, our team has gained new members, we have developed many more games besides Climate Call, and expanded our operations to many more countries, but our core mission remains: to create engaging educational experiences and contribute to a more sustainable future.
