Attclimate dataset

The ATTCLIMATE Survey is a four-wave panel study of the Spanish population fielded between 2023 and 2025. It tracks citizen attitudes towards climate change and support for a broad range of mitigation policies over time, enabling the analysis of opinion dynamics in response to real-world climate events and political developments.

The ATTClimate project is publicly available through the CORA (Consorci de Serveis Universitaris de Catalunya) research data repository. The data are deposited at doi.org/10.34810/DATA3567.
