What do you think causes the largest climate impact? A flight across the Atlantic, eating one steak per day for a year, or heating a house? Find out how everyday activities affect the climate by playing Climate Call! The game is fun, engaging, informative and it typically leads to lively discussions and eye-opening discoveries! One round takes about 15 minutes to play. The game is ideal for a group of 2 to 6 players, 12 years or older. The climate impacts have been estimated using a calculation model developed by researchers at Chalmers University of Technology, Sweden. 

Climate Call is published by Klimatkoll Guldheden AB in Sweden.

“It’s fun and educational at the same time.”

“It’s kind of like being tricked into learning, you know!”

These are the words of some students who have played Climate Call in the school.


The Climate Call game is an excellent resource for everyone who teaches about climate and sustainable development to students aged 12 and above. The game can be used as an effective and educational tool to educate, inspire and engage students within the framework of climate and sustainable development education. As of the year 2023, approximately 50 000 games have been distributed and/or sold, and played by an estimated 500 000 people in total. In Sweden alone, more than 30 000 students have played the card game, and 500 teachers and teacher students have been trained in how the game can be used as an educational tool. 

Our educational initiative began in Sweden in 2020, thanks to funding from Formas – a research council for sustainable development. In 2023, our educational initiative is continuing and expanding to several countries in the Baltic Region thanks to financial support from the Swedish Institute and the Nordic Council of Ministers and fruitful partnerships with local educational organizations. The new project, “Empowering Teachers, Inspiring Pupils: A Transnational Approach to Fun and Engaging Climate Education”, aims to capture the interest and engagement of young people in the climate issue and equip teachers with effective and curriculum-aligned learning resources.

Climate Call can be used by all teachers who teach subjects related to climate and sustainable development, such as natural science, technology, geography, social studies, and home economics. 

Are you a teacher looking for fun and engaging ways to incorporate the topic of climate change into your teaching? Exercises, lesson plans, classroom toolkits and other learning resources can be found under “Teaching Resources”. If you need any further assistance, you are always welcome to reach out to us at, and we’ll be happy to assist you!


Are you curious about how we have calculated the emissions associated with the activities on the cards? Detailed explanations for a selection of cards are available under “Card Calculations”!

If the cards in your deck don’t match the cards for which we provide calculation explanations, you’re probably playing with an older edition of the game. Click on “Different editions of the game” for more information about the differences between the various editions.
