Goal: The Wedge Game is an activity of the Carbon Mitigation Initiative (CMI) of the Princeton Environmental Institute. Permission to use the activity is granted with the caveat that data be shared with CMI. The goal and purpose of the activity as stated by CMI is:

• “To provide hands-on experience with the challenges involved in cutting emissions, CMI developed the “Stabilization Wedge Game” in 2004. It was first used for CMI’s annual meeting, where it was played by 50 players from industry, academia, and the non-profit sector. Subsequent games have been carried out with players from a variety of backgrounds, and the game is adaptable for use with different audiences.”
• “The goal of the game is to build a plausible and politically acceptable portfolio of strategies to keep global carbon emissions flat for the next 50 years. Teams can choose to use each strategy more than once, but must consider the potential physical and economic limitations of each strategy.”

Note: The activity can be used as it is written by CMI or as it has been modified in the lessons link below.
