Despite the central role of committees in shaping the European Parliament’s responses to emerging policy challenges, we lack a clear understanding of how they build consensus on appropriate responses. This is in a large part due to a lack of consistent, large-scale data on committee deliberations and the policy decisions that result. To address this gap in our understanding, we introduce a new corpus of EP committee deliberations and linked policy decisions relating to the effects of global megatrends (deglobalisation / climate change / ageing / digitalisation /automation / urbanisation) between 2009-2024. We then explore how these committees debate and shape policy responses to these challenges. Our findings provide new insights into the policy-making process in the EP and the way in which they meet these large-scale challenges.
