Conducted by IPEC, this survey engaged 2,600 respondents aged 18 and above from all five regions of Brazil between November 25, 2022, and January 26, 2023. Utilizing the Computer Assisted Telephone Interview (CATI) system, the interviews were conducted via telephone with the aid of an electronic questionnaire.
The electronic questionnaire employed for data collection was a translated and adapted version of the national climate perception survey in the United States administered by the Yale Program on Climate Change Communication. To align with Brazilian realities, supplementary questions were incorporated into the survey. These inquiries touched upon subjects such as the Amazon region’s wildfires, public expectations regarding the new government’s actions, and matters concerning the recently established Ministry of Original Peoples and the demarcation of indigenous territories.
IPEC calculated weighting factors to rectify population quotas, drawing from data sourced from PNAD-IBGE. The survey’s sample is a representative cross-section of the Brazilian population aged 18 and above, ensuring a geographically segmented analysis of results. With a 95% confidence level, the margin of error for the total sample stands at two percentage points.
