This course aims to address the whole complexity of climate change, by bringing together the science of climate change, the analysis of impacts, and the economic and engineering strategies to reduce emissions.  In this class, students will be actively engaged in exploring the scientific and economic issues underlying the threat of global climate change and the institutions engaged in negotiating an international response.  Students will also work directly on the City of Atlanta Climate Action Plan through different steps: (i) Assessing the current state of the plan; (ii) Updating mitigation strategies for meeting emissions reduction targets and assessing the feasibility, mitigation contribution, and costs; (iii) Estimating Atlanta Policy cost and overall contribution to the global climate issue.
