Description: Borrowing from Gamification theory and using R Shiny coding we developed an app that puts students in the driver’s seat of decarbonization. The app gives students direct access to information on emissions by sector, over time, by country, and as a function of what we get from activities driving those emissions – wealth, energy, food, etc. This emphasis on not just emissions but the activities that incur emissions helps focus student’s attention on examining what’s important, what’s possible, and what it might cost for a country to decarbonize. This culminates in a mock negotiation where students present the decarbonization plans for their countries and try to negotiate deals to reduce emissions. The app presents a unique tool for teaching of decarbonization as well as research opportunities focused on how plans are developed and what may be pathways for global decarbonization.
