New York, Tokyo or Rio de Janeiro - in KEEP COOL mobil, players take on the leadership of global metropolises. They shape the growth path of their economy and take part in research projects on technologies such as wind power, photovoltaics and energy storage. They deal with political demands, e.g. from environmental organisations and citizens, and influence the decisions of international climate conferences. Cities are dramatically affected by the consequences of climate change; adaptation and protection measures can go some way to preventing this. Starting in the year 2000, the players must constantly weigh up the economic interests of their own city against the global climate protection goal over the course of 100 years - the temperature display in the game shows whether the balance has been achieved. The game design was originally developed by Prof Dr Klaus Eisenack, Nils Marscheider and other project participants at the Humboldt University in Berlin for use in schools, for example.
Playfully exploringCO2 emissions trading
‘With additional elements, individual topics can be flexibly incorporated and discussed in an economic context with a high degree of practical relevance,’ reports HNU Professor Gutiérrez.[GM1] He has repeatedly used the game as a programme item in his current practical week, this time with parallel interaction in Zoom. As an additional component, Prof Gutiérrez has developed a concept forCO2 emissions trading, which was carried out via Zoom. The actual determination of a market price for theCO2 certificates and the submission of offers to sell and buy took place in the main Zoom session. For individual negotiation processes, students were able to retreat to the breakout sessions or use the chat. Even if certain simplifications were naturally necessary in the context of a game onCO2 emissions trading, the implementation nevertheless made it possible to experience the current discussion on the pricing ofCO2 in a playful way. By limiting the quantity of certificates in particular, it was possible to delay reaching the 1.5 degree mark in the game until around 2055 and ultimately limit the simulated global warming to 1.8 degrees in 2100.
