This project will evaluate the political feasibility for signatories of the Paris Agreement under the United Nations Framework Convention on Climate Change (UNFCCC) to effectively implement and iteratively improve their Nationally Determined Contributions (NDCs) such that the rise of global temperature is limited to 2° Cabove pre-industrial levels (or less). We view implementation of countries’ current and future revisions to NDCs to be best characterized as a series of nested collective decision-making processes (CDMPs). As such, we intend to apply the KAPSARC Toolkit for Behavioral Analysis (KTAB) to simulate the domestic CDMP within the top 5emitters, as well as the global CDMP among Paris Agreement signatories.
