Dataset and research materials: Repeated cross-sectional study on social acceptance of biorefineries in the Community of Madrid (2022-2024)

This repository contains the complete dataset and methodological materials from a repeated cross-sectional study on social acceptance of biorefineries in the Community of Madrid (2022-2024), developed within the eCOMCIENCIA project (PID2021-127019OB-I00) and the Community of Madrid projects BIVALIA-CM (TEC-2024/BIO-177) and BIOTRES-CM (S2018/EMT-4344). It provides detailed information on public attitudes and acceptance of sustainability, biofuels, and biorefineries in the Madrid region.
The repository includes:

• Detailed methodological document with theoretical foundation and statistical analysis procedures
• Complete questionnaire with 22 questions (Spanish and English versions)
• Full dataset with 1,068 valid surveys from two independent waves (October 20-31, 2022, n = 532; November 1-5, 2024, n = 536) in .csv and .sav formats
• Codebook with description of all variables
• .spv files with statistical analysis outputs for each questionnaire item
• Detailed analysis reports by thematic block (sociodemographic, sustainability attitudes, waste separation and treatment perceptions, biofuels acceptance, and biorefineries acceptance)
• Python code used to verify the reported results (S3_analysis_code)

The data were collected through a CAWI survey of residents of the Community of Madrid aged 18 and older, recruited from a non-probability online panel (SurveyMonkey) with gender and age quotas, and have been anonymized to ensure compliance with data protection regulations. See readme.txt for coding notes, in particular the treatment of non-responses and the change in the number of options in Q20 between waves. This material constitutes a valuable resource for researchers interested in social acceptance of energy technologies, renewable energies, and sustainable energy transition.
