COST Action CA17132, European Network for Argumentation and Public Policy Analysis (henceforth: APPLY) sets out to “improve the way European citizens understand, evaluate and contribute to public decision-making on such matters of common concern as climate change or energy policies”. It does so by addressing potential discursive gaps that exist between policymakers, citizens and scholars on matters of public policy from a perspective of argumentation, which permits a descriptive and evaluative approach. The task of working group 1 (henceforth: WG1) within APPLY is collecting and annotating existing datasets concerning argumentation and policymaking, organizing them in a pan-European database, which is currently under construction. The present report is an integral part of WG1 efforts to provide a comprehensive overview of existing data on argumentation and policymaking in Europe.
