The aim of this project is to understand how transnational forums, which have been established in recent years to address climate change, affect the discussion, selection and convergence of climate change policies. For this purpose, the research group investigates policy preferences and perceptions of policy measures of different groups of actors (bureaucrats, civil society and business actors) in Argentina, Chile and Mexico as well as impacts of cross-level learning on policy convergence. Further, questions of representation of included and excluded actors will be examined. In this project, an interdisciplinary team of researchers from geography, linguistics, political and social sciences will decipher the mechanisms through which transnational forums on climate governance are both influenced by national positions on climate change policy and, conversely, influence changes and harmonisation of national responses to climate change.
