The Climate Change Conference is a five-party, multi-issue, in-class negotiation simulation that requires no software or other digital means. The exercise develops an understanding of the complex landscape of global climate change mitigation and adaptation measures across various constituencies. At the core of the simulation, students take the roles of representatives from Developed Countries, Developing Countries, the Organization of the Petroleum Exporting Countries (OPEC), Fossil Fuel Companies, and Electric Vehicle (EV) Firms, with each stakeholder having distinct priorities and interests. In a highly interactive small- and large-group negotiation process, participants navigate through three critical issues: (1) securing global net-zero emissions by mid-century by keeping the goal of a maximum 1.5℃ average global temperature rise within reach through (a) meeting emissions reduction targets, (b) coal phase-out, (c) methane reduction, and (d) halting deforestation; (2) protecting communities and natural habitats; and (3) mobilizing climate finance.
