Environmental activism has emerged as a critical force in shaping legislative agendas, yet the precise mechanisms by which protest movements translate public sentiment into policy remain underexplored. This study investigates the relationship between environmental protests and legislative response in Austria, the Czech Republic, Germany, Denmark, the Netherlands, New Zealand, Spain, Sweden, and the United Kingdom, quarterly from 2000-2020. The independent variable, environmental protest, is constructed using the GDELT Realtime Event Database. The dependent variable, government response, is multidimensional in nature, leveraging the ParlSpeech V2 Dataset and Climate Policy data from the Grantham Institute Climate Change Laws of the World database. These techniques allow us to quantify the responsiveness of parliamentary rhetoric to protest activity. Using Callaway and Sant’Anna's (2021) staggered treatment difference-in-differences methodology, we first capture how the emergence of environmental protests impacts rhetorical signaling in parliamentary settings. We then instrument these predicted values to capture their effect on the actual implementation of environmental policy and apply gradient descent optimization to identify the words, tones, and linguistic features from parliamentary speeches most strongly associated with government responsiveness to environmental protests. This research design allows for rigorous examination of legislative response across these nine democratic states, and we construct a comprehensive framework for understanding how environmental movements influence political decision-making. This analysis promises to provide empirical insights into the mechanisms of democratic responsiveness to environmental challenges, bridging existing gaps in understanding between public mobilization and legislative action.
