Study title

We collected data in five East African countries (Kenya, Tanzania, Uganda, Ethiopia and Rwanda) on public opinions about different policy instruments to reduce the use of fossil fuels in the transport sector. The questionnaire also included questions on the dependency on fossil fuels, the level of concern about different environmental challenges, trust in others and in government institutions and socio-demographic characteristics.

Before conducting the interviews, the enumerators completed a two-day training session on the topics in the questionnaire and various techniques for collecting data using the CATI method. A pilot study was conducted in January 2022 with 200 respondents in each of the five focal countries to test the reliability and content validity of the questionnaire. Additionally, the pilot study enabled refining the questionnaire with feedback from both the enumerators and respondents. The company used its existing national databases of respondents involved in earlier investigations to recruit survey respondents in each of the five countries. Screening questions were used to recruit samples that were representative of the adult population in terms of age, gender and area of residence in the five countries. In total, 7,622 respondents were contacted. Following three reminders, a total of 4,766 responses with complete...
