Keep Cool (board game)

Keep Cool is a board game about global warming created by Klaus Eisenack and Gerhard Petschel-Held of the Potsdam Institute for Climate Impact Research and published by the German company Spieltrieb in November 2004. It is both a serious game and a negotiation game: three to six players represent groups of the world's countries, such as the United States, Europe, the Former Soviet Union, OPEC and the Developing Countries, balancing their economic interests against the climate. Each player must meet an economic target of owning enough factories and a secret target dealt on a card; green factories stand for renewable power and black factories for fossil fuels, and the carbometer tracks warming. Greenhouse cards bring regional disasters whose severity depends on the warming reached. The game sold out within four months and has been used by schools, universities and NGOs.
