Ideological drivers of climate obstruction and delay: political parties and public opinion in Spain

Abstract This study contributes to the growing body of international research examining how political actors strategically resist or slow down climate action despite scientific consensus. It combines a cross-sectional public opinion survey with a systematic analysis of political party manifestos. The study identifies clear ideological differences between parties and their supporters in regard to how climate change is framed and addressed. While most respondents acknowledge anthropogenic climate change and express support for stronger government action, significant segments resist lifestyle changes and consider resource extraction to be unavoidable. Left-leaning voters tend to emphasize collective responsibility and call for stronger public intervention. In contrast, conservative and far-right voters are more likely to downplay human causation, prioritize economic growth, and frame climate disruption as being driven by natural forces. Party programs across the political spectrum indeed mirror these tensions by promoting incremental rather than transformative measures. The Far-right nationalist narratives of sovereignty and securitization further serve to delegitimize mitigation efforts. The Old and New Right parties try to avoid regulations and thus oppose decisive government intervention in environmental matters. The findings show that political polarization plays a central role in shaping attitudes towards climate policy in Spain, in line with broader European trends whereby far-right parties promote climate delay narratives. The research also identifies that climate delay is a structural phenomenon, rooted in the intersection of ideologies such as capitalism, nationalism, and patriarchy, rather than a purely partisan one.
